Fire rated sealant near Camden Town

How it works

We work through the job in order: protect, prepare, seal, tidy. Typically it takes anything from a few hours to several days, depending on how many gaps there are. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  2. Anything that isn’t fit for the job comes out, and the gap is cleaned.
  3. Where the tested detail needs backing or fill, we fit it.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Locations and products are noted so you have them on file.

How to prepare

  • Clear items away from the joints we’re working on
  • Mention any sign-in or site rules at work premises
  • Tell us about any water getting in

How we handle fire rated sealant in Camden Town

Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. If you have gaps filled with a product that isn’t fire-rated and gaps flagged on a fire risk assessment, we can help, on flats & HMOs, plasterboard & masonry and linear gaps alike.

London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. For managing agents and building owners in Camden Town, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.

There’s a 12-month guarantee on every job.

Surface by surface

Flats and HMOs

Converted houses often have gaps around old and new services. The gaps on your list are sealed with a fire-rated product and record where they are.

Linear gaps

A linear joint may need to allow for movement as well as fire. We choose a product and depth that suit the gap and the movement.

Landlord and commercial work in Camden Town

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can go on one quote.

For anyone letting property in or around Camden Town, several properties can go on one quote. Send us the addresses and the work at each.

Should I try it myself first?

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Camden Town: your questions answered

Is parking an issue for fire rated sealant in Camden Town?

London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.

Do you work for landlords with property near Camden Road station?

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

Do you cover Camden Town?

Yes. We are based in Crawley and work across South East England, London and Scotland, Camden Town included.

Do I have to be there?

Access is agreed with you when the job is booked. For inside work, that normally means someone being in.

What should I tell you?

Tell us what needs doing and where. We will ask anything else we need to know.

Will it make a mess?

We keep the work tidy. Nearby surfaces are protected.

Where do you work from?

Our base is Crawley. Our area covers South East England, London and Scotland.

Do you take out the old sealant first?

Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.

Do you need fire rated sealant in Camden Town?

In some buildings the gap was filled with the wrong thing in the first place: ordinary expanding foam, standard silicone or decorators’ caulk in a place that needed a tested fire seal. It looks sealed, but it isn’t fire-rated.

The most common problems we see are:

  • Fire stopping disturbed by later work
  • Gaps filled with a product that isn’t fire-rated
  • Gaps where walls meet ceilings or slabs
  • Holes left by a change of layout

Rented homes near Camden Road station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

What fire rated sealant looks like in Camden Town

Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed. There are hotels and other places to stay in and around Camden Town. Hotel work can be planned room by room, with out-of-hours working where needed.

For site and facilities teams at buildings such as Our Lady Roman Catholic Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. If you look after a church, hall or community building such as St Michael's Church, older buildings that have had new heating or wiring often have service gaps worth checking.

How we quote for fire rated sealant

Call for a quick quote. What matters most is:

  • Access and height
  • Mould in or behind the old joints
  • The number and length of the joints
  • The product the joint needs

A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

What we need to know

When you contact us, these details help:

  • Photos by email, if that is easy
  • Any access issues, like height or stairs
  • What the problem is, such as mould, gaps, leaks or cracking

What we can’t put right

A few problems are outside what sealant work can do:

  • A wall that is not a fire-resisting element to begin with
  • Certifying a building or signing off its fire safety
  • Openings too large for sealant, which need batts, boards or another system

If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.
