How we handle fire rated sealant in South Holmwood

We can work through a building room by room or floor by floor, with each location and product recorded. It gives you a list to keep with the building’s fire safety documents. If you are dealing with old fire sealant that has split or come away and sealant items on a fire risk assessment action list, we can help, on plasterboard & masonry, door frames and service penetrations alike.

Somewhere as small as South Holmwood, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

All our work is covered by a one-year guarantee, wherever you are in Surrey.

How it works

Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours for a handful of gaps, and longer for a whole building. Somewhere like South Holmwood needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. Before starting, we go through the specification or action list with you.
  2. We measure every gap and note what it’s in and what passes through.
  3. Unsuitable material such as ordinary foam or silicone is cut out.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. Every location is recorded with the product used for your files.

Preparing for the visit

  • Mention any leaks or damp you’ve noticed
  • Clear the area around the work
  • Mention any tricky access

Surface by surface

Door frames

A door can only do its job if the gap behind its frame is sealed too. We seal that gap with a fire-rated sealant suited to the frame and wall.

Service penetrations

Service penetrations are where new gaps often appear. We clean out what’s there and reseal to the right depth over any backing the detail calls for.

What we can’t put right

We will not take on work that won’t last, so these are the limits:

  • Large holes that need a different fire-stopping system
  • Issuing a fire rating or certificate for a building
  • Deciding what fire stopping a building needs

If you are not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.

How we quote for fire rated sealant

Your quote is based on your job. We look at:

  • How much there is to do
  • Whether the work is at height
  • Any mould that needs treating
  • How much old sealant there is and how hard it is to remove

A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Helping us quote

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • What the problem is, such as mould, gaps, leaks or cracking
  • A few photos by email, if you can
  • The type of property
  • How we’d reach the joints

Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we will talk you through the work and send you a clear quote.

Commercial buildings in South Holmwood

In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

For buildings such as Church of St Mary Magdalene, gaps around pipes and cables are worth checking after any building work there. Managing a site like The Priory CofE Voluntary Aided School? Then gaps opened by contractors for new cabling are a common finding in schools and offices. For landlords with property near Holmwood station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

For landlords and businesses

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can be quoted together.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.

FAQs for South Holmwood

Can you help a landlord with a rental near Holmwood station?

Yes, we work for letting agents and landlords. Just call 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.

Can you do fire rated sealant in South Holmwood?

Yes, South Holmwood is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing.

Can you tell me which gaps need fire stopping?

No. That is for a fire risk assessor, designer or building control. Our job is applying the sealant to their specification.

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.

Is there any odour?

There can be a smell while the sealant cures, but it fades. Opening a window helps.

Do I need to be at home?

It depends on the job. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.

We’re a Crawley-based firm. Our area covers South East England, London and Scotland.

Aftercare tips

Looking after new joints is easy, and it makes a real difference:

  • Store the list of sealed gaps with your building paperwork
  • Ask every contractor to reseal any fire stopping they disturb
  • Do not paint over fire sealant until it has cured
  • Keep photos of seals that will be hidden

Do not add foam, filler or ordinary sealant over a fire seal. If it needs repair, use the same type of product. We can tell you which product we used.

When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.

What happens if it’s left?

If an assessor has flagged gaps, it makes sense to close them before the next review. Getting them done and written up means you can show the action was taken. Where a wall is exposed, as many are in small places like South Holmwood, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Call for a quick quote and we’ll go through it with you.
