How we handle fire stopping in Woodley

Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. Each seal follows the manufacturer’s tested detail rather than guesswork. Site teams most often ask us about penetration schedules that need working through and openings left by services added after handover, on pipe penetrations, joints between fire-resisting walls and floors and service gaps in risers. One point of contact handles commercial sealant work in Woodley from the first photos to the final walk-round, for single jobs and planned programmes alike.

Many town-centre buildings in places like Woodley have had layer upon layer of new services, and each change can leave unsealed holes in walls and floors. Our applicators follow the product’s published detail for that wall or floor whenever fire-rated sealant is the chosen seal.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

When it isn’t the sealant

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Construction that lacks the fire resistance the seal relies on
  • Approving the work on behalf of building control
  • Writing the fire-stopping specification

If you’re not sure, just call 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

Joints and surfaces we work on

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

When to call us in Woodley

Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. It may look closed, but it has no tested fire performance in that position.

Clients usually get in touch after noticing something like this:

  • Builders’ foam or ordinary silicone in compartment walls
  • Fire stopping installed outside its tested range
  • Fire seals cut back for extra cables and never reinstated
  • Unsealed joints where partitions meet the slab

Shop fits on retail sites such as Loddon Vale Shopping Centre (under half a mile east of Woodley) can bring new services through fire-resisting walls between units, to be sealed with the specified product.

What your quote should include

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Do they follow the manufacturer’s priming guidance?
  • Will failed sealant be removed rather than covered?
  • Who will actually carry out the work

How to choose a sealant contractor

How the job changes by surface

Masonry and concrete

Openings through concrete vary from tidy cores to rough break-outs. The gap is measured at the widest point against the detail’s limits.

Small ducts

Ducts are only sealed with sealant where the detail allows it. Dampers and ductwork systems themselves are outside our work.

Common questions from Woodley clients

Could you schedule work at a campus like University of Reading - Whiteknights Campus for the vacation?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Can you seal penetrations in a hotel in Woodley after a refit?

Yes, where the specification calls for fire-rated sealant. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we’ll tell you if the detail calls for a collar, wrap or batt instead.

Is Woodley in your area?

Yes. Woodley is in our area, within our coverage of Greater London, South East England and Scotland. For a quote, call 01277 525 020 or email drawings and photos.

Will you quote for a small job?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

Do you guarantee your work?

Yes. Workmanship is guaranteed for 12 months.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Is it fine to apply new sealant on top of old?

No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

On site: what to expect

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Parking and loading for town-centre jobs in Woodley are worth mentioning when you send details. On estates and business parks it’s typically simpler.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Improvised fillers and failed sealant are removed.
  4. Mineral wool or other backing is fitted where required.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

What we need from you

  • Send asbestos survey details if the building is pre-2000
  • Move anything stored against the joints
  • Tell us which areas need to stay in use

Ask for a quote

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, give us a call on 01277 525 020 or send details through our quote form.

For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. Woodley is about 35 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls.

At a healthcare site like Royal Berkshire Hospital, 2.7 miles west of Woodley, new services through compartment walls are a constant, and each needs the specified seal.

Should maintenance staff do it?

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

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.

Looking after the joints

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Keep general-purpose fillers away from compartment walls
  • Settle who seals which penetrations at the start of a project
  • Check risers and ceiling voids after each round of works
  • Flag new cables with no seal around 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.

Ask every contractor who works in risers or voids to report openings they create. It costs little and catches breaches early.
