Lightning Protection | J Lacey http://www.jlacey.com/blog Fri, 26 Feb 2016 09:00:34 +0000 en-GB hourly 1 http://wordpress.org/?v=4.2.2 What is the purpose of a church steeple? http://www.jlacey.com/blog/what-is-the-purpose-of-a-church-steeple/ http://www.jlacey.com/blog/what-is-the-purpose-of-a-church-steeple/#comments Fri, 26 Feb 2016 09:00:34 +0000 http://www.jlacey.com/blog/?p=344 Steeples are commonly seen on Christian churches because they enhance the lines of the building and create an aesthetically pleasing effect. The shape and design is also said to have been created to naturally attract attention and draw the eyes heavenward, encouraging a sense of spirituality and religious contemplation.

The steeple also makes the structure stand out from surrounding buildings. This was important for three reasons. Firstly it was believed that the steeple could be used to help people tell the time by noting the position of the sun. Secondly it would house the bells and ensure they were elevated above other buildings so the sound wouldn’t be blocked and would therefore travel further. Finally, the height of the structure meant people would see it so they would know where to go to worship, even if they were new to the area.

Unfortunately the height of the steeples can also cause potential problems. The size means they tower above the rest of the building, leaving them exposed to all weather conditions. It also makes it tricky to monitor wear and tear and carry out repairs. As a result the building materials can get worn and damaged, potentially putting the stability of the whole spire at risk.

Inspecting and repairing church steeples takes a lot of skill and experience. The height and difficulty of accessibility mean that a safe, secure solution is needed. Typically this will be scaffolding but it could also involve abseil or platform access if it is possible. It is crucial to choose the right option for each specific property, accounting for the stability of the structure and maximising safety.

At J Lacey Steeplejacks Contractors we regularly take on church restoration projects, alongside a wide range of other industrial services including masonry repairs, lead work and even repairing weathervanes. No matter what kind of project we are working on, we will work hard to maximise safety for all parties. This can include installing netting to offer protection against falling debris.

If you would like to arrange a professional inspection for a church steeple please contact us. We will provide a clear assessment of the condition and give you recommendations of work we feel is needed to repair and stabilise the structure.

Bird proofing that won’t leave a bad impression http://www.jlacey.com/blog/bird-proofing-that-wont-leave-a-bad-impression/ http://www.jlacey.com/blog/bird-proofing-that-wont-leave-a-bad-impression/#comments Wed, 24 Feb 2016 09:00:49 +0000 http://www.jlacey.com/blog/?p=342 In urban settings, property owners can face many challenges when it comes to managing birds. Ledges and roofs will be attractive perches to them and also make handy locations for nests, leading to droppings, feathers and other debris. If left unmanaged the presence of the birds can lead to health concerns as they can carry various bacteria, viruses and parasites that can be harmful to humans.

Bird proofing systems can help to tackle the problem, particularly when they are designed to effectively deter birds from landing on the structure. There are a number of options to choose from so you can select the right one for your particular setting. When deciding which type of system to use, it is important that it does not harm the birds or detract from the aesthetics of the property.

One of the best options on the market is Avishock. The system is very discreet so it can be added to any property without risking marring the facade, which means it can be successfully installed on modern and heritage structures alike. It is also incredibly flexible so it can be installed on all manner of facades, including flat and curved surfaces.

Avishock works in a similar way to electric fences for livestock, albeit with a much smaller current. It delivers a small, harmless shock to the birds that touch it in order to deter them from landing, roosting or nesting on a structure. This encourages the birds to adjust their behaviour and keep away from your property.

At J Lacey Steeplejacks Contractors we are proud to offer the market leading Avishock system to property owners across the UK. We can help them to tackle their bird problems whilst also being very careful to protect the aesthetics of the structure. We will install systems in the most discreet manner so they are unobtrusive and don’t spoil the appearance of the property. If you would like further information about the system or want to discuss costs with us, we would be happy to advise you. Please contact us for details.

Carrying out comprehensive concrete repairs http://www.jlacey.com/blog/carrying-out-comprehensive-concrete-repairs/ http://www.jlacey.com/blog/carrying-out-comprehensive-concrete-repairs/#comments Mon, 22 Feb 2016 09:00:52 +0000 http://www.jlacey.com/blog/?p=340 When concrete begins to degrade, it can lead to major problems for the building. Once a crack appears in a concrete structure, it is important that it is repaired at the earliest possible point. When cracks are left unresolved they can escalate and lead to large scale and expensive repair jobs.

There are many contributing factors to foundation cracks, including low quality workmanship and material use during construction, the location and age of the premises, and several other natural and sometimes unavoidable issues. There are some areas that are inherently vulnerable to excessive weather conditions, changing temperatures and shaking ground and all buildings are susceptible to wear and tear as the years go on. Concrete can also begin to degrade after exposure to fire, bacterial corrosion and damage from chemicals and force or impact.

It is crucial to use a professional company for all concrete repairs, as it is possible for cracks to appear during the original construction phase which may require specialised repair work. Concrete repair materials dry quickly which can make the process challenging. As professional steeplejacks, we are able to carry out high quality repairs that ensure optimal results.

We can complete all concrete remedial tasks swiftly and effectively. We make use of the finest materials and we can carry out work to the highest possible standards. Once all work is complete, we will inform you when the repaired materials can be used, and our customers can always be assured of the quality of our work.

Our team have vast experience in a wide range of areas from industrial roofing, cleaning and fencing to the installation of bird proofing, debris netting and lightning and surge protection systems. We use safe methods to access all high rise structures and we operate in accordance with every established health and safety standard. If you need any kind of work carrying out on a high structure, please do not hesitate to get in touch and find out how we can provide the ideal service for you.

Repairing and restoring 19th century churches http://www.jlacey.com/blog/repairing-and-restoring-19th-century-churches/ http://www.jlacey.com/blog/repairing-and-restoring-19th-century-churches/#comments Fri, 19 Feb 2016 09:00:54 +0000 http://www.jlacey.com/blog/?p=337 There was a huge increase in the number of churches being constructed around the country throughout the 19th century. This was due to population increases and general revivalism in the Church of England. The return to ancient forms of worship brought about the need for new furnishings and equipment within the church. The new manufacturing areas such as London and the North of England had high volumes of people wanting to attend church, but not enough churches to accommodate them.

There were 10,000 churches in the UK at the beginning of the 19th century, but a survey taken in 1872 revealed that a further 3,204 churches had been built by that time. Additionally, 925 existing churches had been rebuilt entirely. The dioceses of England were required to report how many churches had been restored or built at a cost of more than £500. The total cost equates to approximately £1.2 billion in today’s money.

In almost 150 years since the construction and rebuilding of many of the UK’s churches, several have fallen into severe decline. There are currently over 1000 churches in desperate need of restoration. Churches play a crucial role within many communities, and we know the importance of maintaining their condition.

As experienced steeplejacks we are able to offer a safe and high quality church restoration service. We have spent many years at the forefront of the sector and we can access all high rise structures and carry out comprehensive and efficient restoration work.

We use only state of the art materials and equipment and we strictly adhere to all relevant health and safety regulations. On site safety is of paramount importance to us, and we can be trusted to carry out the most professional and reputable work. Our team are able to complete all high rise access projects including weather vane adjustment, flag poles, lead work and full masonry repairs.

Once the roof of a church has been secured, it offers long term security and durability. Churches are used for events and meetings for local schools, groups and charitable organisations. They are multi-functional venues and a stable roof can offer a warm and sheltered environment for over a century.

We are committed to providing carefully devised remedial plans and high quality workmanship to assist the problem of the failing churches throughout the country. We offer a comprehensive and cost-effective service that also includes building services, industrial cleaning, concrete repairs and the installation of lightning protection systems.

Protecting gutters from acid rain damage http://www.jlacey.com/blog/protecting-gutters-from-acid-rain-damage/ http://www.jlacey.com/blog/protecting-gutters-from-acid-rain-damage/#comments Wed, 17 Feb 2016 09:00:02 +0000 http://www.jlacey.com/blog/?p=335 Many of us have made efforts to live in a more environmentally friendly way over the last few decades, and many of these steps have had a significant and very beneficial effect. One of the clearest ways this can be seen is in the dramatic reduction of acid rain levels we now experience in the UK. A push to reduce sulphur and nitrogen emissions has seen a fall in man made contributions towards acidity in rainwater, with the measured level currently 90% lower than it was in the 1980s. However, the reality is that neither we nor the rest of the world can ever be completely free of acid rain. This is something which must be kept in mind when arranging cleaning services for roofs and gutters.

Whether falling as storms or as snow, rainwater has a natural acidic quality to it. Even if we ceased all human activates which contribute to it, the natural release of sulphur and nitrogen oxides from forests, volcanoes and the oceans would mean acid rain remained a part of life. While the work to reduce acid rain has been both admirable and essential, we have to accept that this kind of rain is always going to be with us in some form.

It is easy to see when a storm has brought acid rain as we will be left with dirty looking marks or streaks across our windows after a storm passes. While in the majority of cases these windows can be washed and no lasting harm is caused to the glass, the same is not always true of gutters. Traces of acid rain may be left soaking into gutters, causing damage and eroding their normal lifespan.

As part of our industrial services, we can carry out thorough and professional gutter cleaning to combat the damage caused by the presence of acid rain. Our team of roofers and steeplejacks are qualified to use the SkyVac system, the world class gutter cleaning technology which is widely viewed as the very best available. In addition to ensuring all debris and blockages are cleared, our use of SkyVac will significantly limit the damage caused to your gutters by acid rain.

The measures we have taken to reduce man made pollution have been significant and effective. While there is little we can do about stopping natural causes of pollution, our gutter cleaning services can help you ensure the damage is limited.

Food businesses are vulnerable to bird problems http://www.jlacey.com/blog/food-businesses-are-vulnerable-to-bird-problems/ http://www.jlacey.com/blog/food-businesses-are-vulnerable-to-bird-problems/#comments Mon, 15 Feb 2016 09:00:13 +0000 http://www.jlacey.com/blog/?p=332 Nuisance birds have always been an issue, but in recent years the numbers of birds causing problems by nesting on top of buildings has risen substantially. Species such as starlings, sparrows and feral pigeons are constantly on the hunt for water, shelter and food and they are extremely resourceful when creating nests atop and inside buildings.

Urban bird control has become a necessity for many buildings, including warehouses and other industrial and commercial facilities. It is essential to protect professional premises, their contents and the people that work inside them. Pigeons, gulls and sparrows are just a few of the nuisance birds that have become a serious problem in industrial settings, and pigeons can be a particularly big problem as they tend to mate for life and will not readily vacate a nest.

Pest birds can also cause substantial problems for food establishments such as restaurants, cafes and takeaways. They have incredible vision and are able to distinguish between ultraviolet and infrared in the UV spectrum. They can easily identify food and heat, which will of course draw them to any place where food preparation is going on.

When birds identify a food source they will build a nest and begin to leave droppings. Their excrement causes contamination, spreads germs and leads to a greater insect presence. The major issue with their faeces is the acidic content as it stains roofs and leads to surface deterioration. Once this occurs it can cause a whole new set of problems. Furthermore, their droppings and feathers can get trapped in chimneys and ventilation shafts leading to the risk of fire and the spread of disease.

If you need help to alleviate this issue, we can offer you high quality bird proofing solutions. You can select from netting, bird spikes and electronic systems that have been specially designed to deal with the destructive presence of birds. Our quality Avishock system offers harmless bird management and determent and an effective solution to the problem of nesting birds on, around and inside buildings.

Protecting buildings from spring and summer storms http://www.jlacey.com/blog/protecting-buildings-from-spring-and-summer-storms/ http://www.jlacey.com/blog/protecting-buildings-from-spring-and-summer-storms/#comments Fri, 12 Feb 2016 09:00:44 +0000 http://www.jlacey.com/blog/?p=330 The National Oceanic and Atmospheric Administration National Weather Service estimates that there are approximately 1,800 thunderstorms in occurrence at any given time. This translates to around 16 million thunderstorms every year. The average thunderstorm will last around 30 minutes and usually measure about 15 miles in diameter.

The two biggest threats presented by thunderstorms are flash floods and lightning, and as they depend on moisture and warmth, it stands to reason that they will occur more in the warmer seasons. The higher humidity and warmer temperatures together create moist air that rises and results in a thunderstorm.

Clouds can be seen as giant generators. They are filled with millions of ice particles and water droplets. Evaporation produces droplets that collide with other moisture, knocks off electrons and creates a charge separation. The electrons collect at the base of the cloud and provide it with a negative charge and the rising moisture without an electron carries a positive charge to the top.

The rising moisture freezes at this elevated point, and the unfrozen droplets become positively charged. The charge separation has an electric field associated with it, and just like the cloud, it is negative in the lower region and positive at the top. As the collisions and freezing continue, the electric field becomes more intense and surface electrons are sent deeper into the earth by the negative charge at the lower portion of the cloud. As electrons are repelled it causes the surface of the earth to acquire a strong positive charge. The electric field then creates a conductive path through the air and results in lightning.

Spring and summer are just around the corner, so now is widely considered the best time to equip vulnerable buildings with lightning protection systems. We can help our clients to keep their properties, inhabitants and electrical equipment safe by installing state of the art lightning and surge protection solutions. We can advise you on all aspects of protection and recommend the best systems for your specific needs.

British people have a deep love for their churches http://www.jlacey.com/blog/british-people-have-a-deep-love-for-their-churches/ http://www.jlacey.com/blog/british-people-have-a-deep-love-for-their-churches/#comments Wed, 10 Feb 2016 09:00:41 +0000 http://www.jlacey.com/blog/?p=328 The National Churches Trust recently carried out a survey which showed more than half of adults in Britain think that more Government funding should be provided to churches. This news comes at a time when it has been announced that Shrewsbury Cathedral will receive a £750,000 renovation, which will be partly enabled by Government funds. It is hoped that this will signal more new investments into the future of Britain’s churches.

The survey reflects the deep respect and affection that people have for the churches in the UK. These buildings are significant not only to people with religious beliefs, but to everyone in the community. They are the sites of some of the most important events in our lives, including Christenings, marriages and funerals, and are places where people come together and are unified. Besides this, they are often also beautiful and historically significant examples of architecture which have stood for many decades, if not centuries.

However, due to age, many of them have unfortunately fallen into disrepair, and in some cases this has rendered them unsafe to use. In these instances, professional restoration can reverse the damage and help to preserve these important buildings for future generations. We completely understand the significant role that churches play in their local communities, and we strive to ensure that they can continue by providing professional and skilled church restoration services.

When it comes to churches, it is important to know that the work is being carried out by highly skilled professionals who have a deep respect for the building. When our services are being used, there are no such concerns. All our steeplejacks are fully trained in different aspects of church restoration and know how to access high areas using the safest and most suitable techniques. Besides restoring existing damage, we can also install systems to safeguard against potential future hazards, such as lightning strikes.

Installing proactive lightning protection http://www.jlacey.com/blog/installing-proactive-lightning-protection-2/ http://www.jlacey.com/blog/installing-proactive-lightning-protection-2/#comments Mon, 08 Feb 2016 09:00:13 +0000 http://www.jlacey.com/blog/?p=326 In matters of safety it is always better to be proactive and put preventative measures in place than to react only when a problem arises. This is particularly true when it comes to lightning protection because it is very difficult to predict when it will occur and where it will strike. An efficient lightning protection system will protect the property, its contents and inhabitants, and will give you peace of mind even if it is never needed.

When we are designing a lightning protection system we always keep in mind that the current can enter a property by striking it directly, by flowing through pipes in the ground, or via cables. Once it enters the structure it can travel through the electrical system, plumbing, air conditioning and even the rebar in the walls or floors. All of these possibilities need to be considered in order to maximise safety.

The best lightning protection systems consist of a grounding system to prevent lighting from striking the property directly and surge protection to stop the current from flowing through cabling. The grounding will consist of a series of conductors to carry the current away from the property, creating a single unobstructed path or several routes so the current can make its way to rods driven into the ground. This allows safe dispersion of the current into the earth. The ground rods need to be positioned carefully to ensure the current can’t jump to any cables or pipes buried in the ground if the system is called into action.

Grounding and surge protection can also help to reduce the risk of fire in the event of a lightning strike. If the current strikes an unprotected property the huge amount of energy can cause conductors to heat up to incredible temperatures, potentially igniting any flammable materials touching them. This is particularly problematic with cables because it could lead to a fire at any point along the wiring.

We have extensive experience with Coventry lightning protection and can create bespoke systems for all properties, ensuring they are protected as effectively as possible. If you have any questions or would like to arrange a consultation please contact us and we will be happy to help.

Churches can sustain serious damage from strikes http://www.jlacey.com/blog/churches-can-sustain-serious-damage-from-strikes/ http://www.jlacey.com/blog/churches-can-sustain-serious-damage-from-strikes/#comments Fri, 05 Feb 2016 09:00:05 +0000 http://www.jlacey.com/blog/?p=322 Churches are the heart of many towns and communities, but due to age and lack of funding many of them are in decline. A further problem facing churches is their susceptibility to lightning strikes. When a church is struck by lightning, it can suffer considerable damage, leading to even further disrepair.

An unprotected church is five times more likely to be damaged by a strike than one with a protection system in place. Prevention is always better than cure, so it’s advisable to take every possible step to defend a church building from possible lightning strikes. The installation of a quality system equips a church with the protective solutions it needs and ensures that the electrical energy within a strike can be directed safely to the ground.

Protection systems are concerned with direct strikes, a strike in the vicinity of the structure, a strike to the service cable that supplies the structure or a strike close to a power or telephone cable. Overall, once a system is installed it offers protection to the structure itself, the surrounding environment and the people and electrical equipment inside.

When systems are installed there should always be sufficient separation between the lightning conductors and other conducting material, particularly the wiring system. As experienced steeplejacks and leading suppliers of protective systems, we are able to provide all churches with optimal defence from dangerous lightning strikes.

Once your system has been installed, we can offer a comprehensive testing and maintenance service. Our Coventry steeplejacks have plenty of experience in high rise access projects and can carry out safe and efficient installations. We know that all structures differ in their protection needs, so we ensure each church is fitted with the right system. We serve customers on a nationwide basis and provide an affordable and professional service.
