Fire stopping across Ash Vale

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

What we’re called out for in Ash Vale

Plenty of openings were simply never closed. They come to light during inspections, refits or when another trade lifts a tile.

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

  • Snag lists that include open service penetrations
  • Service penetrations left open after M&E works
  • Fire seals cut back for extra cables and never reinstated
  • Open linear gaps along the top of fire-resisting walls

For an estates team at a campus like University for the Creative Arts, which lies south-west of Ash Vale, summer M&E works are typically followed by a round of penetration sealing.

Questions to ask before you book

  • Whether old or failed sealant will be cut out, not overlaid
  • Will CSCS-carded applicators be on site?
  • Are they CHAS accredited or on Constructionline?
  • Whether primer will be used where the manufacturer specifies it

Questions to ask before you appoint anyone

Fire stopping in Ash Vale, done properly

Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail rather than guesswork. If you are dealing with open linear gaps along the top of fire-resisting walls and fire stopping installed outside its tested range, we can put it right, whatever the surface. For commercial sealant work in Ash Vale, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Buildings in a smaller place such as Ash Vale 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.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Your questions answered

Can you work in a care home near Ash Vale with residents in?

Yes, with the manager deciding the order and timing of rooms. Tell us about any infection-control or safeguarding requirements and we’ll work to them.

Can work at a site such as University for the Creative Arts fit around teaching?

Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Will you sign off the seals for us?

No. We don’t certify or sign off fire stopping, and we hold no third-party fire-stopping installer certificate. Our part is fitting the specified product to its tested detail, and any records you need can be confirmed with the quote.

Do you work in Ash Vale?

Yes. Ash Vale is in our area. To discuss a job, give us a call on 01277 525 020 or send photos by email.

How soon can the area be used again?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

How do I request a quote?

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

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Our process

On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work usually takes a single visit for a short list of penetrations, or a phased programme for a whole building. For a job in Ash Vale, the main thing is a clear picture of the work, so send photographs of each area. A fixed quote follows.

  1. First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  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.

Preparing the site

  • Share your working hours and any access restrictions
  • Move anything stored against the joints
  • Tell us which areas need to stay in use

Work for main contractors and building owners

CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

Why act early in Ash Vale

The longer openings stay, the more there tend to be: each new service adds to the list. Keeping on top of it after each round of works keeps the job small and avoids a much larger catch-up later. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.

The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

What you get with us

  • CSCS-carded applicators
  • Sealing commercial buildings since 2005
  • One phone line for London, the South East and Scotland
  • Health and safety: CHAS accredited

Take a look at how commercial sealant jobs are priced or our accreditations and insurance.

Maintenance after handover

To get the most from the new sealant:

  • Agree the fire-stopping specification before services go in
  • Brief every trade that openings they make must be sealed
  • Keep product data and details in the fire safety file
  • Check risers and ceiling voids after each round of works

Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted.

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

Fire stopping around Ash Vale: how the place shapes the job

The 2 miles around Ash Vale include three care or nursing homes. 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. At about 32 miles from central London, Ash Vale is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product.

In a retail centre such as Westgate Shopping Centre, 2.2 miles south-west of Ash Vale, any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail. Colleges such as Aldershot College, 1.6 miles to the south-west of Ash Vale, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.

  • Large openings beyond what any sealant detail covers
  • Writing the fire-stopping specification

If in doubt, give us a call on 01277 525 020 or email a schedule or drawings and we will say what we think.
