Fire stopping across Egham

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Why it’s worth doing now in Egham

Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. For businesses and landlords in Egham, a tidy, sound joint also matters for appearance. Fresh sealant makes a building look maintained.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Why appoint us

  • Our applicators hold CSCS cards
  • Public liability insurance in place
  • Sealing commercial buildings since 2005
  • Specification-led, product-correct work

About our fire stopping in Egham

Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. We use sealant where it is the specified product, and we tell you when a detail calls for something else. We work on service gaps in risers, cable penetrations and linear gaps at wall heads, and what we are called in for most is unsealed penetrations discovered above suspended ceilings and open linear gaps along the top of fire-resisting walls. Most enquiries from Egham start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Many town-centre buildings in places like Egham have had layer upon layer of new services, with gaps around pipes and cables left after each change. Our applicators follow the product’s published detail for that wall or floor whenever fire-rated sealant is the chosen seal.

Work we carry out in Surrey comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or email us and we’ll come back to it.

Fire stopping around Egham: points for this area

Plenty of hotels sit less than 2 miles from Egham. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. Egham is about 20 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls.

For an estates team at a campus like Royal Holloway University (0.8 miles west of Egham), summer M&E works are usually followed by a round of penetration sealing. In a hotel such as The Runnymede Hotel on Thames, 0.7 miles north-east of Egham, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.

When to call us in Egham

When a seal departs from its tested detail, the evidence no longer covers it. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are what we find most often.

Typical triggers for a call:

  • Openings found when ceilings come down for a refit
  • Fire-rated sealant that has cracked or shrunk back
  • Expanding foam used as fire stopping
  • Damaged fire seals in risers and voids

At a healthcare site like Ashford Hospital, 3.5 miles east of Egham, new services through compartment walls are a constant, and each needs the specified seal.

What your quote should include

  • Health and safety accreditation such as CHAS
  • Will failed sealant be removed rather than covered?
  • Is the sealant right for the movement and the substrate?
  • How joint depth will be controlled

Questions to ask before you appoint anyone

Egham: questions and answers

Could you schedule work at a campus like Royal Holloway University for the vacation?

Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Egham?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

Can you quote from photographs?

That depends on the size and complexity of the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.

Is it fine to apply new sealant on top of old?

No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

When something else is needed

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Approving the work on behalf of building control
  • Walls or floors that aren’t fire-resisting to begin with
  • Large openings beyond what any sealant detail covers

If you’re not sure, just call 01277 525 020 or use the quote form and we will give you a straight answer before you book.

What we seal

  • Linear gaps at wall heads
  • Joints between fire-resisting walls and floors
  • Service gaps in risers
  • Small duct penetrations where the tested detail allows
  • Pipe penetrations
  • Cable penetrations

What affects the price in Egham

Your fixed quote is built from the real scope. It takes account of:

  • How much existing material needs removing
  • Phasing around occupants
  • Specialist products, such as fire-rated or hygienic sealants
  • Distance, for remote addresses

There’s no price list, since every building and every scope is different. Call for a quote.

Details that help us quote

The more we know, the firmer the quote. Helpful details to send:

  • Where the site is, with the postcode
  • Whether an asbestos survey exists
  • What the building is and how it’s used
  • A wide shot and a close-up of the area

Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. The easiest way is to phone 01277 525 020 or email us.

Aftercare for building managers

After handover, these steps help:

  • Leave fire sealant to cure fully before covering it
  • File the specified details where the next contractor can find them
  • Agree the fire-stopping specification before services go in
  • Check risers and ceiling voids after each round of works

Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t.

Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.

How a job runs

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes a single visit for a short list of penetrations, or a phased programme for a whole building, and our waste is bagged and taken away as we go. For a town like Egham, we try to group jobs for the same client into one visit, with one quote covering them. Give us your access times and we’ll fit the work in.

  1. First we go through the drawings, schedule or specification for the seals.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Getting the site ready

  • Let us know about inductions and permits
  • Confirm the product named in the specification
  • Point out any areas we must not close

Ask for a quote

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call 01277 525 020 or send photos by email with what you know.
