Fire stopping across Middle Stoke

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Fire stopping in Middle Stoke

It helps to set out our role at the start. 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. If you are dealing with hidden openings found during inspections and fire sealant pulled out of the opening, we can put it right. A single leaking joint is often how a building in Middle Stoke first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

For a smaller site near Middle Stoke, we plan to do all the penetrations in one go, 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.

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 are clear about what is covered before work starts.

Questions we are asked in Middle Stoke

Is a smaller place like Middle Stoke outside your area?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Will you design a fire-stopping scheme for our building in Middle Stoke?

No, that sits with the designer, fire engineer or building control. We install fire-rated and intumescent sealant around service penetrations and linear gaps where it is specified, to the manufacturer’s tested detail.

Can you quote from photographs?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Are you CHAS accredited and on Constructionline?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

What do you charge?

Every job gets its own fixed quote. To get one, phone 01277 525 020 or email drawings and photos with a description of the work.

Diagnose, treat, sign off

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself normally taking longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Rural sites near Middle Stoke may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. We read the specification, drawings or penetration schedule you send and ask about anything unclear.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. Mineral wool or other backing goes in wherever the detail asks.
  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

  • Explain the parking and delivery arrangements
  • Point out any areas we must not close
  • Move anything stored against the joints

Ask for a quote

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, phone 01277 525 020 or email drawings and photos.

General trades versus a specialist

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

How the job changes by surface

Plastic pipes

Plastic waste pipes through slabs come up often. Whether sealant alone is acceptable depends entirely on the tested detail.

Masonry and concrete

Block walls and concrete floors are common substrates for penetration seals. Dust and debris are cleared from the opening.

Building owners, agents and FMs in Middle Stoke

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

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

Honest limits

Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:

  • Writing the fire-stopping specification
  • Plastic pipes whose detail calls for a collar or wrap
  • Gaps in walls that were never built as compartment walls

If you’re not sure, just call the office on 01277 525 020 or email the details over and we’ll give you a straight answer.

Joints and surfaces we work on

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

What happens if it’s left?

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach. Around Middle Stoke, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote once you have the details.

Why appoint us

  • Work to your specification and the manufacturer’s guidance
  • Fixed quotes based on photos, drawings or a visit
  • Fully insured
  • One phone line for London, the South East and Scotland

Compartment walls and floors in Middle Stoke

Central London is about 32 miles from Middle Stoke. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product. In England, Approved Document B covers fire stopping of 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.

For a building such as Church of St Peter and St Paul, new heating or data runs are the usual reason penetrations need sealing. In a school such as Stoke Primary Academy, fire-rated sealant goes in around service penetrations where it is specified.
