Fire rated sealant near Gun Hill

Surface by surface

Door frames

Frame gaps are usually hidden behind the architrave. We seal any open gap to the product’s tested details so the architrave can be refitted.

Service penetrations

Service penetrations are where new gaps often appear. Old or unsuitable filler comes out before the right sealant goes in with backing where the detail needs it.

How we handle fire rated sealant in Gun Hill

We often work from an action list drawn up by a fire risk assessor for buildings in Gun Hill. Send us the list or the survey and we’ll quote for the fire-rated sealant work on it. We’re often asked to deal with gaps filled with a product that isn’t fire-rated and gaps flagged on a fire risk assessment, across flats & HMOs, pipe & cable gaps and door frames.

In a village or hamlet like Gun Hill, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

Our work is backed for twelve months, in Gun Hill and everywhere else we cover.

Common questions in Gun Hill

Is Gun Hill within the area you cover?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Is there a guarantee on fire rated sealant in Gun Hill?

Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.

Do I have to be there?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Will there be a smell?

There can be a smell while the sealant cures. Opening a window helps.

Do you work in flats, HMOs and commercial buildings?

Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Let us know the building’s hours and we’ll plan the work to suit.

How long will you be here?

As a guide, most jobs take anything from a few hours to several days, depending on how many gaps there are. Bigger jobs take longer.

Do you have insurance?

Yes. We are fully insured, and we’ve been doing sealant work for more than 20 years.

Can you seal over the old sealant?

No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.

How the visit works

A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. Most jobs take a few hours for a handful of gaps, and longer for a whole building. Somewhere like Gun Hill needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. Before starting, we go through the specification or action list with you.
  2. Each gap is measured and its substrate and service noted.
  3. Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
  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.

Getting ready for the visit

  • Plan for the work area to be out of bounds to pets and children
  • Tell us about any water getting in
  • Tell us if parking is tricky

Advice

Do you need fire rated sealant in Gun Hill?

Door frames are a common weak spot. The gap between the frame and the wall is hidden behind the architrave, so it can be left open when a door is replaced.

Most people get in touch after spotting one of these:

  • Unsealed gaps around fire door frames
  • Seals cut through by electricians, plumbers or data installers
  • Gaps filled with a product that is not fire-rated
  • Gaps around pipes and cables through fire-resisting walls

For jobs in and around Gun Hill, choosing the right material for each joint is as important as a tidy finish.

What fire rated sealant looks like in Gun Hill

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

In and around Gun Hill, as anywhere, good fire rated sealant starts with a clean, dry, properly prepared joint.

Why act early in Gun Hill

For some gaps, sealant isn’t the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. We’ll say so if a gap needs something other than sealant. Where a wall is exposed, as many are in small places like Gun Hill, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

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 the work is at height. We take all of that into account in your quote.

DIY sealant or a professional job?

Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

Keeping the joints in good condition

Joint life depends on how it’s used and looked after. We suggest:

  • Check risers, ceiling voids and cupboards during building checks
  • Ask which product was used before you paint
  • Allow for resealing whenever new services are run
  • Store the list of sealed gaps with your building paperwork

Don’t drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.

Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.
