Fire stopping near Whitehill

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Honest limits

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Deciding what a wall or floor needs, which belongs to the designer
  • Large openings beyond what any sealant detail covers
  • Walls or floors that aren’t fire-resisting to begin with

If in doubt, phone 01277 525 020 or email us and we’ll say what we think before you book.

Where we work in Whitehill

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

Fire stopping in Whitehill

We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance in Whitehill and nearby. We work on joints between fire-resisting walls and floors, linear gaps at wall heads and cable penetrations, and the usual reasons a site gets in touch are fire-stopping items raised at inspection or handover and seals disturbed by maintenance and left open. One point of contact handles commercial sealant work in Whitehill from the first photos to the final walk-round, whether it’s one building or several.

For a smaller site near Whitehill, we plan to do all the penetrations in one go, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.

Work we carry out in Kent comes with a 12-month guarantee. Should something we installed fail, call the office on 01277 525 020 or use the quote form and we’ll come back to it.

Signs you need fire stopping in Whitehill

Head-of-wall joints and wall-to-wall junctions are frequent weak points. Movement in the frame or slab can open the joint, and the wrong product can split as a result. The tested detail for a linear joint states the width and movement it covers.

It’s worth sending us details if you spot any of the following:

  • Damaged fire seals in risers and voids
  • Fire-stopping items raised at inspection or handover
  • Fire-rated sealant that has cracked or shrunk back
  • Fire stopping installed outside its tested range

Older community buildings such as Church of St Peter and St Paul that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Before you book anyone

  • Are they CHAS accredited or on Constructionline?
  • Whether their applicators hold CSCS cards
  • How joint depth will be controlled
  • Do they follow the manufacturer’s priming guidance?

Questions to ask before you appoint anyone

Whitehill: questions and answers

Is Whitehill too far out for you?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can you seal around new services in a hotel near Whitehill?

Yes, to the specification and the product’s tested detail. We match the product to the wall or floor and the services, and say if something other than sealant is needed.

Are you insured?

Yes. We’re fully insured, including public liability cover.

How do we ask for a quote?

You can use the quote form on this site; alternatively, call 01277 525 020 or email a schedule or drawings. Photos, drawings or a joint schedule help us quote quickly.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Do you take on multi-site work?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

Can the building stay open while you work?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

Our process

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Whitehill, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  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. We compare every service penetration with its tested detail before sealing.
  4. Foam, ordinary sealant and debris come out so the seal starts clean.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

What we need from you

  • Flag any permit to work we’ll need
  • Tell us your opening times and when work is allowed
  • Explain the parking and delivery arrangements

Advice

When to bring in a specialist

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Redoing a failed joint normally 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 Whitehill

Whitehill is about 44 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.

Schools such as Ospringe Church of England Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. In a hotel such as Premier Inn Faversham Hotel (0.5 miles north-east of Whitehill), new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.

Whitehill is about 1 mile south-west of Faversham, in Kent. We cover Whitehill and the rest of Kent, with the same fixed quotes and 12-month guarantee as everywhere else. Whitehill is one of 931 places we cover in Kent. London is covered too, some 44 miles away.

What sets the cost

To price the job, we consider:

  • Travel to remote or island sites
  • How much there is to seal
  • The site’s rules and procedures
  • Whether old sealant has to be cut out first

A quote for service penetrations depends on quantities, condition and access. Ask us for a fixed quote.

Before you send an enquiry

A few photos plus some basic facts will normally do. It helps to include:

  • Your programme or deadline
  • Specification clauses that apply
  • Clear photos of the problem areas
  • Anything awkward about access or site hours

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 drawings and photos.

Why it’s worth doing now in Whitehill

Open penetrations multiply: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable and avoids a much larger catch-up later. Halls, stores and units around places like Whitehill may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.
