Fire stopping across Tulse Hill

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

Our process

Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. All of Greater London is in the ULEZ, and kerbside space in Tulse Hill can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. We start with your penetration schedule, drawings or specification.
  2. Access, permits and the order of areas are agreed with the site team.
  3. We compare every service penetration with its tested detail before sealing.
  4. Unsuitable material is removed and the opening cleaned first.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

Getting the site ready

  • Share the asbestos register for older buildings
  • Agree which areas must stay open
  • Share your working hours and any access restrictions

Advice

How we handle fire stopping in Tulse Hill

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, ring 01277 525 020 or email the details over with the schedule or marked-up drawings and the specified product data. Tell us what records you need and we’ll confirm with the quote. Most enquiries involve damaged fire seals in risers and voids and unsealed openings around new pipes and cables, across small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and pipe penetrations. For commercial sealant work in Tulse Hill, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

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’ll confirm with the quote.

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

Doing it in-house

Putting right a botched joint often costs more than sealing it well at the start, 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 we can’t put right

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Writing the fire-stopping specification
  • Construction that lacks the fire resistance the seal relies on
  • Large openings beyond what any sealant detail covers

If in doubt, ring 01277 525 020 or email drawings and photos and we will say what we think before you book.

Where we work in Tulse Hill

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

Fire stopping in Tulse Hill: the local picture

With tenants changing and fit-outs following, London buildings see service routes altered again and again. Penetrations are sealed with the specified product, to its tested detail, under the building’s own permit rules. There are a good number of hotels within about 2 miles of Tulse Hill. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail.

Workshops and IT rooms at colleges like William Booth College (to the north-east of Tulse Hill) are re-serviced often, leaving penetrations to seal. For a hospital such as Lambeth Hospital, 1.5 miles to the north-west of Tulse Hill, penetration sealing is normally phased ward by ward, with infection-control rules agreed first. Residences at universities like King's College London (1.8 miles north-east of Tulse Hill) have compartment walls that must be resealed whenever services change.

Tulse Hill is about 1 mile north-east of Streatham, in Greater London. Any commercial site in Tulse Hill is covered, whether it’s a single job or part of a planned programme. Our Greater London coverage takes in 764 places, large and small.

Building owners, agents and FMs in Tulse Hill

Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

Looking after the joints

Regular inspection catches problems early. Specifically:

  • Put resealing into every M&E and fit-out package
  • Foam or ordinary sealant is never a fire-seal repair
  • Agree the fire-stopping specification before services go in
  • Check with the data sheet before painting over fire sealant

Once the seals are in, tell other trades they exist and must not be disturbed. If a seal has to be opened for a new service, it should be reinstated to the same detail.

On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned, and the work runs in step with the M&E.

Why act early in Tulse Hill

Open penetrations multiply: each new service adds to the list. A schedule that is dealt with regularly stays manageable and avoids a much larger catch-up later. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.

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 fixed quote when you are ready.
