Fire stopping for Mytchett sites

Common problems we fix in Mytchett

A common fault is a product that was never fire-rated in the first place: builders’ foam or ordinary silicone used to fill a hole. The opening looks sealed but has no fire test evidence behind it, so it has to come out.

Things that usually lead to an enquiry:

  • Seals that don’t match their tested detail
  • Old intumescent sealant that has split away
  • Builders’ foam or ordinary silicone in compartment walls
  • Fire-stopping items raised at inspection or handover

For a hotel such as Lakeside International Hotel, which lies north of Mytchett, penetration seals are worth checking after any refit or services upgrade.

About our fire stopping in Mytchett

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. Before we seal anything, we check the opening against the detail it is meant to follow, and we say so if it doesn’t fit. We work on service gaps in risers, linear gaps at wall heads and joints between fire-resisting walls and floors, and what we’re called in for most is penetration schedules that need working through and unsealed penetrations discovered above suspended ceilings. Whoever orders the work in Mytchett, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Converted and extended buildings around places like Mytchett can mix old and new construction, so the wall or floor a service passes through isn’t always what the drawings assume. The right product depends on the wall or floor and the services passing through, and we will tell you if the detail calls for something other than sealant.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Maintenance after handover

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Keep general-purpose fillers away from compartment walls
  • Agree the fire-stopping specification before services go in
  • Arrange inspection before areas are covered up
  • File the specified details where the next contractor can find them

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.

A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate, which saves guesswork.

Site staff or a sealant specialist?

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Common questions from Mytchett clients

Is Mytchett too far out for you?

No. Places such as Mytchett are covered as much as the big towns. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.

What happens to BS 476 references for fire stopping in Mytchett?

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes 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.

How do I request a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.

When can you be on site?

We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

Can weather delay the job?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

For managing agents and facilities managers

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

What we can’t put right

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Reviewing a building’s overall fire safety
  • Construction that lacks the fire resistance the seal relies on
  • Signing off or certifying a building’s fire stopping

Not sure which it is? You can call the office on 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

Surfaces we seal

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

On site: what to expect

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. For a site in Mytchett, 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. We compare every service penetration with its tested detail before sealing.
  4. Unsuitable material is removed and the opening cleaned.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

What we need from you

  • Let building users know which areas are affected
  • Explain the parking and delivery arrangements
  • Tell us your opening times and when work is allowed
