Fire stopping in Brockham, done properly

No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. Before we seal anything, we check the opening against the detail it is meant to follow. The enquiries we see most involve penetration schedules that need working through and open linear gaps along the top of fire-resisting walls, across service gaps in risers, linear gaps at wall heads and pipe penetrations. Facilities teams, main contractors and managing agents in Brockham tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

A job near Brockham is typically planned around one visit, with the specification and photos sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or use the quote form and we will arrange a return visit.

What sets the cost

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • Induction, permit and paperwork requirements
  • Any access equipment needed
  • Removal of failed or old sealant
  • How much there is to seal

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Details that help us quote

Whether it’s one area or a whole building, the same details help:

  • Clear photos of the problem areas
  • Rough lengths or quantities, or drawings if you have them
  • Where the site is, with the postcode
  • Whether an asbestos survey exists

Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we’ll return a fixed quote you can plan around. For a chat about it beforehand, speak to us on 01277 525 020 or use the quote form.

For managing agents and facilities managers

As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first.

Questions we are asked in Brockham

Can you work on a hospital site such as Dorking Community Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Can you work in a care home near Brockham with residents in?

Yes. We agree rooms and times with the manager and work a few areas at a time. We follow the home’s own procedures throughout.

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

Do you hold third-party fire-stopping installer certification?

No, and we won’t imply otherwise. Some clients require third-party installer schemes even though the law doesn’t. If it doesn’t require one, we can install the specified fire-rated sealant to its tested detail.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.

What does an EI 60 rating mean?

Penetration seals are tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. Results are classified under BS EN 13501-2. The rating applies to the product as tested.

Diagnose, treat, sign off

At the end of each section, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. Smaller jobs around Brockham can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. The specification and schedule come first, so we know which details apply.
  2. We plan the sequence of floors, risers and voids with you.
  3. We compare every service penetration with its tested detail before sealing.
  4. Unsuitable material is removed and the opening cleaned so the seal starts clean.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

Getting the site ready

  • Tell us your opening times and when work is allowed
  • Send any specification or drawings in advance
  • Let us know about inductions and permits

Ask for a quote

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.

When to call us in Brockham

Most open service penetrations are left by later work. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser leaves an opening that nobody returns to. Over a few years of fit-outs, a wall can collect a lot of these.

Common reasons buildings call us in:

  • Snag lists that include open service penetrations
  • Fire-rated sealant that has cracked or shrunk back
  • Seals disturbed by maintenance and left open
  • Improvised or mixed-product fire seals

For a hospital such as Dorking Community Hospital, which lies west of Brockham, penetration sealing is typically phased ward by ward, with infection-control rules agreed first.

Comparing quotes

  • Whether old or failed sealant will be cut out, not overlaid
  • Which product they’ll use, and why it suits the joint
  • How they’ll work around occupants
  • How the joint faces will be prepared and primed

Fire stopping around Brockham: what changes locally

For England, the fire stopping of penetrations is dealt with in Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. The 2 miles around Brockham include two care or nursing homes. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail.

Offices at parks like Chesterfield Business Park, 2.2 miles east of Brockham, are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. Holiday works at schools like North Downs Primary School often leave service openings to seal before pupils return.

Brockham is about 2 miles east of Dorking, in Surrey. Anywhere in RH3, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. 379 places across Surrey fall within our area, including Brockham. Sites around London have their own page, about 20 miles away.

When to bring in a specialist

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

After the work

After handover, a little attention goes a long way:

  • Check risers and ceiling voids after each round of works
  • Keep general-purpose fillers away from compartment walls
  • Report damaged or disturbed seals as soon as they’re spotted
  • Get seals inspected before ceilings and boxing close

New services after handover are a common way fire stopping gets breached. A short check at the end of each job saves a long hunt later.

Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job; found late, it can be one of many.
