Fire stopping for commercial buildings in Wimbledon Chase

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, give us a call on 01277 525 020 or email drawings and photos with the schedule or marked-up drawings. Tell us what records you need and we’ll confirm with the quote. The enquiries we see most involve openings left by services added after handover and open linear gaps along the top of fire-resisting walls, on cable penetrations, small duct penetrations where the tested detail allows and pipe penetrations. Looking for mastic applicators who cover Wimbledon Chase? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Taller residential buildings in London may fall under the Building Safety Act’s higher-risk regime, where fire-stopping records get close attention. Our part is installing the specified fire-rated sealant; tell us what records you need and we will confirm with the quote.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Questions we’re asked in Wimbledon Chase

Do you take on jobs in Wimbledon Chase where loading and access are tightly controlled?

Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry.

Could you schedule work at a campus like Kingston University Roehampton Vale Campus for the vacation?

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Will you sign off the seals for us?

No. Sign-off belongs to the designer or building control, not the installer. We will confirm the product and detail installed, and you can tell us what other records you need at quote stage.

Will you come and look before quoting?

It depends on the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.

Do you take on multi-site work?

Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.

What does an EI 60 rating mean?

In short, BS EN 1366-3 and 1366-4 are the fire tests and BS EN 13501-2 is how results are classified. An EI 60 seal kept its integrity and insulation for 60 minutes as tested; installing to the detail is what carries that across to site.

Are you insured?

Yes. We’re fully insured, and the certificate can go with your quote.

What we’re called out for in Wimbledon Chase

Some service penetrations were never sealed at all because they sat out of sight above a ceiling or inside a riser. They come to light during inspections, refits or when another trade lifts a tile.

Typical triggers for a call:

  • Improvised or mixed-product fire seals
  • Fire seals cut back for extra cables and never reinstated
  • Old intumescent sealant that has split away
  • Openings left by services added after handover

At a university such as Kingston University Roehampton Vale Campus (2.6 miles north-west of Wimbledon Chase), labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.

What your quote should include

  • How joint depth will be controlled
  • The named product and why it was chosen
  • How long is the guarantee, and what does it include?
  • How the joint faces will be prepared and primed

Questions to ask before you appoint anyone

Fire-rated sealing for Wimbledon Chase buildings

In England, Approved Document B covers fire stopping of openings and penetrations. 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. Our part stays the same: the specified product, installed to its tested detail. There are plenty of hotels within about 2 miles of Wimbledon Chase. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with the specified product.

For a unit at a site such as Nelson Trading Estate (0.8 miles east of Wimbledon Chase), new power or data runs between office and warehouse can breach a compartment wall. For a site team at a college like Wimbledon College of Arts, under half a mile north of Wimbledon Chase, fire-rated sealing is best scheduled after the summer works.

Wimbledon Chase is about 1 mile south of Wimbledon, in Greater London. Anywhere in SW19, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 764 places in Greater London. For work in that direction, see our London page, about 8 miles away.

If you need fire stopping in SW19, SW20 and SM4, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. Buildings on Edna Road, Manor Road and Dorien Road are within our area for service penetrations. Close to Wimbledon Chase, our area also takes in Merton Park (1 mile east), Bushey Mead (1 mile west), Cannon Hill (1 mile south), Wimbledon (1 mile north) and Raynes Park (1 mile south-west). A short drive away, we cover London (8 miles north-east), City of Westminster (8 miles north), Marylebone (8 miles north), Kensington (6 miles north), St Pancras (9 miles north-east) and Shoreditch (10 miles north-east).

Maintenance after handover

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Agree the fire-stopping specification before services go in
  • Don’t let anyone top up a fire seal with the wrong product
  • Flag new cables with no seal around them
  • Make fire stopping part of every scope that crosses a fire-resisting wall

Don’t patch a fire-rated seal with anything outside its tested detail. A repair should use the original product, installed the same way.

Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small; found late, it can be one of many.

Our process

Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.

  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.

Getting the site ready

  • Send any specification or drawings in advance
  • Flag any permit to work we will need
  • Point out any areas we must not close

Quotes

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

When it isn’t the sealant

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:

  • Large openings beyond what any sealant detail covers
  • Reviewing a building’s overall fire safety
  • Approving the work on behalf of building control

Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

Joints and surfaces we work on

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

Site staff or a sealant specialist?

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Why act early in Wimbledon Chase

The longer openings stay, the more there tend to be: each new service adds to the list. A schedule that is dealt with regularly stays manageable, rather than turning into a full building survey and reseal. Getting scaffold, permits or access booked in Wimbledon Chase takes effort, so it makes sense to deal with every failing joint while access is in place.

A quote for service penetrations depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.
