Fire stopping for commercial buildings in Tinsley Green

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 in Tinsley Green and nearby. We work on small duct penetrations where the tested detail allows, service gaps in risers and pipe penetrations, and what we’re called in for most is fire seals cut back for extra cables and never reinstated and unsealed penetrations discovered above suspended ceilings. Most enquiries from Tinsley Green start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Around smaller places like Tinsley Green, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant.

Fire stopping in Tinsley Green: the local picture

Three care or nursing homes sit less than 2 miles from Tinsley Green. 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. There are plenty of hotels within about 2 miles of Tinsley Green. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product.

Colleges such as Crawley College, 2.2 miles south-west of Tinsley Green, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. On estates like Forge Wood Industrial Estate, 0.6 miles to the south-west of Tinsley Green, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal. Shop fits in centres such as County Oak Retail Park (to the south-west of Tinsley Green) can bring new services through fire-resisting walls between units, which then need the specified seal.

Doing it in-house

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Quoting for work in Tinsley Green

A fixed quote reflects the actual work. It takes account of:

  • Location, for remote and island sites
  • How much there is to seal
  • Backing rod, priming and other preparation
  • The site’s rules and procedures

A quote for service penetrations depends on quantities, condition and access, and any specification that applies. Call for a quote.

Details that help us quote

However big the job, the same details help:

  • When you need the work done
  • Whether the building will be occupied during the work
  • The asbestos register, for older buildings
  • The product your specification calls for

To get a fixed quote, give us a call on 01277 525 020 or use the quote form, telling us the site location and the nature of the job. Our quote form is another easy route.

Questions about Tinsley Green

Can you work around term dates at a campus such as Crawley College?

Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is Forge Wood Industrial Estate, near Tinsley Green, within your area?

Yes, sites like Forge Wood Industrial Estate are within our area, along with the rest of Tinsley Green. To start, just call 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

Do you have third-party installer accreditation for fire stopping?

No, and we won’t imply otherwise. Third-party schemes aren’t a legal requirement, but many clients and main contractors ask for them, so it’s worth checking what your contract says. If it doesn’t require one, we can install the specified fire-rated sealant to its tested detail.

What do you charge?

There isn’t a price list, as every site differs. Send photos or drawings and we’ll price it at a fixed figure.

Is your workmanship covered by a guarantee?

Yes. Workmanship is guaranteed for 12 months on every job.

Does the weather affect the work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Looking after the joints

Keep the joints in good shape with a few simple steps:

  • Flag new cables with no seal around them
  • Check risers and ceiling voids after each round of works
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Agree the fire-stopping specification before services go in

Never top up a fire seal with foam, ordinary silicone or filler. A repair should use the original product, installed the same way, or a new specification from the designer.

Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.

Diagnose, treat, sign off

Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. If others near Tinsley Green need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

  1. We read the specification, drawings or penetration schedule you send.
  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. We fit the backing the detail asks for, to the stated depth.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Preparing the site

  • Point out any areas we must not close
  • Tell us your opening times and when work is allowed
  • Warn occupants and staff about the work

Advice

When it isn’t the sealant

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

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Signing off or certifying a building’s fire stopping
  • Openings that need collars, wraps, batts or boards rather than sealant

Not sure which it is? You can call 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

Surfaces we seal

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