About our fire rated sealant in Hamsey

Deciding which gaps need fire stopping is not our role; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. Common call-outs are for standard silicone or caulk in a fire-stopping gap and gaps left after a refit or conversion, on door frames, linear gaps and plasterboard & masonry.

Work in a small place like Hamsey is planned ahead, journey included, so it can be fitted around guests, clients or events where possible.

The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or send us an email.

Leave it or put it right?

An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the sealing itself is often a contained piece of work. Where a wall is exposed, as many are in small places like Hamsey, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.

Quotes for fire rated sealant in Hamsey

You will get a clear quote before any work starts. It’s based on:

  • Whether the work is at height
  • The type of sealant required
  • The size of the job
  • How many rooms, windows or areas are involved

Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or email us and we’ll give you an honest view and a quote.

Helping us quote

Photos help, but a description is a good start. Try to tell us:

  • The rough size of the job
  • Any access issues, like height or stairs
  • Whether it’s a home or a business
  • Whether it has been sealed before

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.

Keeping the joints in good condition

To keep the joints looking good and working properly:

  • Do not fill fire-stopping gaps with ordinary foam or silicone
  • Do not paint over fire sealant until it has cured
  • Allow for resealing whenever new services are run
  • File the fire-stopping record where your assessor can find it

Do not drill through or remove a fire seal without putting it back properly. New services through a sealed wall should include fire stopping in the plan.

Open gaps do not only matter in a fire: noise, draughts and even pests can come through too. Sealing them early helps on every front.

What sealant work cannot fix

Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:

  • Assessing a building’s fire safety
  • A wall that is not a fire-resisting element to begin with
  • Problems with the door itself rather than the gap around the frame

Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly.

Surfaces we seal

  • Linear gaps
  • Flats & HMOs
  • Service penetrations

Hamsey: your questions answered

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

Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.

Do you cover smaller places like Hamsey?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Are you an approved applicator?

Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.

Do you work in flats, HMOs and commercial buildings?

Yes. We work in flats, HMOs, schools, offices and other commercial buildings, including occupied ones. The order of work and access are planned with you.

How long will you be here?

It depends on the size of the job, but most jobs take anything from a few hours to several days, depending on how many gaps there are. We will tell you when we quote.

Do you carry out fire risk assessments?

No. Your fire risk assessor, designer or building control decides that. Our job is applying the sealant to their specification.

Can you fill the gap behind a fire door frame?

Yes. The joint between frame and wall is sealed with a fire-rated sealant following the tested details. The door leaf and its hardware need a door specialist.

Does someone need to be in?

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.

What we do, step by step

All our tools and materials come with us in the van. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. For a village or hamlet like Hamsey, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. We go through the gaps on your list or survey and check each one’s size and substrate.
  2. Anything that is not fit for the job comes out, and the gap is cleaned.
  3. Where the tested detail needs backing or fill, we fit it.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. Locations and products are noted so you have them on file.

Before we arrive

  • Keep pets and children clear of the area while we work
  • For indoor joints, keep the area dry beforehand if you can
  • Let us know about stairs, lifts or work at height

Common problems we fix in Hamsey

Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. We see plenty of fire stopping that was hurried, especially where it was squeezed in at the end of a project.

Keep an eye out for these signs:

  • Fire seals that have cracked with movement
  • Open gaps behind door architraves
  • Open joints along the top of partitions
  • Unsealed gaps where pipes and cables go through a wall

For site and facilities teams at buildings such as Hamsey Community Primary School, fire-stopping around service openings should be restored whenever new services go in.

Choosing a sealant specialist

Commercial buildings in Hamsey

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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.

Rented homes near Cooksbridge station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. If you look after a church, hall or community building such as The Parish Church of St Peter, older buildings that have had new heating or wiring often have service gaps worth checking.
