Fire rated sealant near Euston

Fire rated sealant for homes and businesses in Euston

Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t a fire-rated seal. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. We work on pipe & cable gaps, linear gaps and service penetrations, and people most often call us about open holes round services passing through fire walls and new service routes left unsealed after building work.

In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. In Euston, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.

All of our work is guaranteed for twelve months, in Euston and everywhere else we cover.

Can I do it myself?

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

How it works

A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. It usually takes anything from a few hours to several days, depending on how many gaps there are. In Euston, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  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. We fit backing where needed and apply the fire-rated sealant to depth.
  5. We hand over a list of locations and products for your records.

Getting ready for the visit

  • Tell us about any water getting in
  • Try not to wet indoor joints just before the visit
  • Move anything stored near the joints

Advice

Aftercare tips

Looking after new joints is easy:

  • Check whether a sealant can be painted before decorating over it
  • Keep the record of products and locations with your fire safety documents
  • Tell trades working in the building that fire seals must be put back
  • Photograph sealed gaps before they’re covered up

Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some cannot, so ask us which we used.

It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes.

Common problems we fix in Euston

Sometimes the wrong product was used from the start: ordinary expanding foam, standard silicone or decorators’ caulk in a place that needed a tested fire seal. It may look fine, but it isn’t a fire-rated seal.

Keep an eye out for any of the following:

  • Gaps around pipes and cables through fire-resisting walls
  • Gaps flagged on a fire risk assessment
  • New service routes left unsealed after building work
  • Seals cut through by electricians, plumbers or data installers

As a London address, Euston can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Questions to ask before booking

  • What guarantee comes with the work
  • Who turns up on the day
  • Whether all the old sealant comes out first
  • How long to leave it before use

Choosing a sealant specialist

Different surfaces, different methods

Service penetrations

Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. We seal it with a product tested for that service and gap size.

Door frames

Frame gaps are normally hidden behind the architrave. Where it’s open, we seal it to the product’s details for that gap size before the trim goes back.

Fire rated sealant around Euston

Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed. Euston has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.

Managing a site like UCL School of Slavonic and East European Studies? Then service openings in fire-resisting walls need checking after any refurbishment. If you let a flat or house near London Euston station, any gap left by new services in shared walls should be closed with a fire-rated product.

Leave it or put it right?

An unsealed gap lets smoke and fire get round a wall that was built to hold them back. A proper seal lets the wall do its job again, and the sealing itself is often a contained piece of work. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Euston, the repair is bigger than the sealant job would have been.

We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or drop us an email and we’ll talk you through it.
