Fire stopping in Silchester

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

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:

  • Openings that need collars, wraps, batts or boards rather than sealant
  • Walls or floors that aren’t fire-resisting to begin with
  • Fire doors, dampers or other fire safety equipment

If you’re not sure, just speak to us on 01277 525 020 or email us and we will give you a straight answer before you book.

What we seal

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

Fire stopping in Silchester, done properly

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate and we’d rather say that up front. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. If you have service penetrations left open after M&E works and openings found when ceilings come down for a refit, we can put it right, on cable penetrations, pipe penetrations and linear gaps at wall heads alike. Facilities teams, main contractors and managing agents in Silchester tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

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

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

From enquiry to sign-off

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes a single visit for a short list of penetrations, or a phased programme for a whole building, and we clear our waste as we work. Smaller jobs around Silchester can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. First we confirm the product and tested details named in the specification.
  2. Openings are measured and grouped by detail.
  3. Old or wrong materials are cut out.
  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. Completed areas are checked with you, with the records agreed when we quoted.

Before we start on site

  • Warn occupants and staff about the work
  • Point out any areas we must not close
  • Share the asbestos register for older buildings

Quotes

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.

Advice

Silchester: questions and answers

Do you take on work at healthcare sites like Basingstoke and North Hampshire Hospital?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Is Silchester off your patch?

Not at all. Silchester is within our area. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.

Which standards are fire seals tested to?

BS EN 1366-3 covers penetration seals and BS EN 1366-4 covers linear joints. Results are classified under BS EN 13501-2, where E is integrity, I is insulation and the number is minutes, as in EI 60. That rating only holds when the product is installed to its tested detail.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

What’s the quickest route to a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

What site paperwork can you supply?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

Compartments and services around Silchester

Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. Silchester is about 45 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal.

On a hospital site such as Basingstoke and North Hampshire Hospital, 5.1 miles to the south of Silchester, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. Holiday works at schools like Silchester Church of England Primary School often leave service openings to seal before pupils return.

Silchester is about 2 miles east of Tadley, in Hampshire. We send applicators to Silchester for service penetrations, handled exactly as we handle every other area. Silchester is one of 723 places we cover in Hampshire for service penetrations. We also cover Reading, around 8 miles from Silchester.

Building owners, agents and FMs in Silchester

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Silchester. Several sites can go on one quote, so there’s one set of paperwork to deal with.

When to call us in Silchester

Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is when untested combinations creep in, which then have to be put right.

These are often picked up first by site or facilities staff:

  • Old intumescent sealant that has split away
  • Improvised or mixed-product fire seals
  • Hidden openings found during inspections
  • Head-of-wall gaps with no fire seal

Where a unit on an estate such as Stacey Industrial Park, which lies west of Silchester, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.

  • Their pre-qualification and accreditations

  • Their plan for phasing and protecting the area

Choosing a commercial sealant contractor

Why it’s worth doing now in Silchester

Open penetrations multiply: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable. Around Silchester, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote once you have the details.

Why clients in Silchester choose us

  • CSCS-carded applicators
  • Sealing commercial buildings since 2005
  • Fully insured, including public liability cover
  • Products installed to the manufacturer’s instructions

See our cost guide and our accreditations.

How the job changes by surface

Metal pipes

Sealant details often cover copper and steel pipework. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail and we confirm each before sealing.

Small ducts

Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Bigger ducts and fire-resisting ductwork are normally handled with other products.
