Need fire stopping in Banstead?

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 Banstead

Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. While the openings can be reached, sealing them is normally straightforward. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. In a smaller place such as Banstead, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

Why appoint us

  • A Constructionline member, so easy to vet
  • Over 20 years of commercial sealing
  • 12-month guarantee on workmanship
  • Work carried out by CSCS-carded applicators

How we handle fire stopping in Banstead

A fire-rated sealant is only one part of a tested system: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in, and we say so if it doesn’t fit. We work on service gaps in risers, cable penetrations and linear gaps at wall heads, and the usual reasons a site gets in touch are non-fire-rated filler around services and service penetrations left open after M&E works. A single leaking joint is often how a building in Banstead first comes to us: we look at the rest while we’re there and tell you what we find.

Buildings in a smaller place such as Banstead that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Different surfaces, different methods

Plastic pipes

Plastic waste pipes through slabs come up often. The detail decides whether sealant alone is enough.

Risers and ceiling voids

Voids hide a lot of unsealed openings. We work through the areas on your schedule methodically and tell you about openings outside the list.

General trades versus a specialist

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. Getting these wrong normally costs more in the end than doing them right.

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Compartment walls and floors in Banstead

Four care or nursing homes sit less than 2 miles from Banstead. Where new services have gone through compartment walls in a care setting, the gaps need the specified product. We install fire-rated sealant to the tested detail where it is specified. Banstead is about 13 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.

At a university such as University for the Creative Arts - Epsom, 2.8 miles west of Banstead, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. Industrial units on estates such as Ullswater Industrial Estate, 2.9 miles east of Banstead, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal. At a healthcare site like Royal Marsden Hospital, 1.4 miles to the north of Banstead, new services through compartment walls are a constant, and each needs the specified seal.

Banstead is about 3 miles west of Coulsdon, in Surrey. Any commercial site in Banstead is covered, for single jobs and planned programmes alike. We work across 379 places in Surrey, large and small. Our London page has more on work in that area.

Questions we are asked in Banstead

Is hospital work, at somewhere like Royal Marsden Hospital, something you do?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

What does the BS 476 change mean for fire-rated sealant in Banstead?

References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

Which sealant will you use?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Do you cover Banstead?

Yes. We cover Banstead, and the simplest way to start is to phone 01277 525 020 or email us.

Do you guarantee your work?

Yes. The 12-month guarantee covers our preparation and application, though not damage or work by other trades.

How the quote is worked out

Each job is priced on its own details. The things that drive the figure:

  • Joint width, depth and condition
  • Whether old sealant has to be cut out first
  • Site requirements such as inductions and permits
  • How accessible the joints are

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.

Sending details for a quote

It doesn’t need to be a full survey. These details are enough to start:

  • Rough lengths or quantities, or drawings if you have them
  • Whether an asbestos survey exists
  • Anything awkward about access or site hours
  • The product your specification calls for

For a fixed quote, call the office on 01277 525 020 or email the details over, telling us the site location and the nature of the job. Our quote form is another easy route.

Our process

Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For a site in Banstead, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  1. The specification and schedule come first, so we know which details apply.
  2. Access, permits and the order of areas are agreed with the site team.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out first.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. Anything outside the detail is reported to you rather than sealed.

Getting the site ready

  • For older buildings, check the asbestos register before work
  • Agree which areas must stay open
  • Tell us what induction or permit system the site runs

Advice

For managing agents and facilities managers

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
