Fire stopping across Pingewood

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

Aftercare for building managers

A few simple habits keep the new joints working:

  • File the specified details where the next contractor can find them
  • Look above ceilings when tiles are lifted for other jobs
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Don’t let anyone top up a fire seal with the wrong product

Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original.

Write fire stopping into the scope of any work crossing a compartment wall or floor. Then the seal goes in while the area is open, not months later.

Fire stopping in Pingewood, done properly

No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. We match each opening to that detail before any sealant goes in, and we say so if it doesn’t fit. The enquiries we see most involve unsealed openings around new pipes and cables and penetration schedules that need working through, on service gaps in risers, linear gaps at wall heads and cable penetrations. A single leaking joint is often how a building in Pingewood 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.

Rural conversions around Pingewood can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

What happens if it’s left?

An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail, so it makes sense to get it right first time. Halls, stores and units around places like Pingewood may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Why appoint us

  • 12 months’ guarantee on every job
  • One contact handling all your sites
  • Old sealant cut out, never sealed over
  • Fully insured

On site: what to expect

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For work around Pingewood, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  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. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Getting the site ready

  • Warn occupants and staff about the work
  • Arrange parking or a loading space
  • Make sure the joints can be reached

Where services cross fire walls in Pingewood

Fire stopping of openings and penetrations in England falls under Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. We install whatever has been specified, to the product’s tested detail. At about 40 miles from central London, Pingewood is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls.

Tenant changes at parks like Green Park Business Park (0.9 miles east of Pingewood) bring new data and services, and openings through fire-resisting walls need the specified seal. Large healthcare estates like Berkshire Independent Hospital, 1.9 miles north-east of Pingewood, change their services often, so penetration seals are worth checking after M&E work.

Pingewood is about 2 miles south-west of Reading, in West Berkshire. Any commercial site in Pingewood is covered, for single jobs and planned programmes alike. Pingewood is one of 140 places we cover in West Berkshire for service penetrations.

Close to Pingewood, our area also takes in Burghfield Bridge (1 mile north-west), Southcote (2 miles north), Fords Farm (2 miles north-west), Horncastle (2 miles north-west) and Trash Green (2 miles west).

When to call us in Pingewood

Plenty of openings were simply never closed because they sat out of sight above a ceiling or inside a riser. Inspections, refurbishments and ceiling access usually bring them to light.

What tends to prompt an enquiry:

  • Unsealed joints where partitions meet the slab
  • Seals that don’t match their tested detail
  • Fire sealant pulled out of the opening
  • Fire seals cut back for extra cables and never reinstated

At a college such as Integration College, 2.7 miles north-west of Pingewood, checking penetration seals after summer M&E works is good practice.

What your quote should include

  • Their pre-qualification and accreditations
  • What level of public liability insurance do they hold?
  • Will CSCS-carded applicators be on site?
  • Can the work be phased to keep areas open?

Choosing a commercial sealant contractor

General trades versus a specialist

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

What sets the cost

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • Specialist products, such as fire-rated or hygienic sealants
  • Induction, permit and paperwork requirements
  • Joint width, depth and condition
  • Whether old sealant has to be cut out first

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

What to include in your enquiry

To price the job accurately, we need to understand the site. Send us:

  • Clear photographs of the problem areas
  • Rough lengths or quantities, or drawings if you have them
  • Specification clauses that apply
  • When you need the work done

The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or call the office on 01277 525 020 or send photos by email to discuss it first.

Common questions from Pingewood clients

Will you plan work around the academic year at somewhere like University of Reading?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is Pingewood too small for you to travel to?

Not at all. Pingewood 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.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

What if there’s asbestos in the old mastic?

The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Can you seal any opening with fire-rated sealant?

No. Sealant is the right product only where the tested detail says so. Collars, wraps, batts and boards exist for openings sealant doesn’t cover, and we flag those rather than improvise.

Do you work in Scotland as well as England?

Scotland sets its own building regulations, with Technical Handbooks. Either way, we install the specified sealant to its tested detail.

Are you insured?

Yes. We’re fully insured, including public liability cover.
