Fire stopping in Roehampton: the local picture

Approved Document B is the English guidance that covers fire stopping around openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. A number of hotels sit less than 2 miles from Roehampton. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.

Campus buildings at universities such as University of Roehampton (under half a mile west of Roehampton) see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. At a college such as South Thames College Wandsworth Campus, 2 miles east of Roehampton, checking penetration seals after summer M&E works is good practice.

Roehampton is about 2 miles south-west of Fulham, in Greater London. Any commercial site in Roehampton is covered. 764 places across Greater London fall within our area, including Roehampton. We also cover London, some 7 miles away.

If you need fire stopping in SW15 and SW13, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. Among the streets we cover are Rodway Road, Cortis Road and Torwood Road, and sites on any of them can send details for a fixed quote. If your building is just outside Roehampton, we cover Putney (1 mile north-east), Barnes (1 mile north), Mortlake (1 mile north-west), East Sheen (1 mile north-west) and Putney Vale (2 miles south-west). Bigger towns within reach include London (7 miles north-east), City of Westminster (5 miles north-east), Marylebone (6 miles north-east), Kensington (3 miles north-east), St Pancras (7 miles north-east) and Shoreditch (8 miles north-east).

Fire stopping for commercial buildings in Roehampton

Opened ceilings and riser doors often reveal service openings nobody sealed. If a specification already covers those walls and floors, we can reseal to it. Where there isn’t one, the designer or fire engineer needs to set one first. Site teams most often ask us about openings left by services added after handover and snag lists that include open service penetrations, across small duct penetrations where the tested detail allows, pipe penetrations and cable penetrations. For commercial sealant work in Roehampton, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

In London, higher-risk residential buildings under the Building Safety Act bring extra scrutiny of fire-stopping records. We install what the designer or fire engineer has specified, and if you need records of the work, tell us and we’ll confirm with the quote.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

How the job changes by surface

Cables and cable bundles

New data and power cables are the most common breach we see. Openings around new cables are resealed to the detail, and we tell you if the bundle exceeds what sealant covers.

Drylining partitions

Service holes through plasterboard are frequently oversized or ragged. An oversized hole may be outside the sealant’s range and we will tell you what the detail says instead.

Cost factors for service penetrations

Each job is priced on its own details. The things that drive the figure:

  • Travel to remote or island sites
  • How accessible the joints are
  • Quantities, in metres or numbers
  • The size and state of each joint

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Sending details for a quote

Good information means a firmer quote. Helpful details to send:

  • The site address and postcode
  • Photos of the joints, close up and from further back
  • Drawings or a marked-up plan, if available
  • Whether the building will be occupied during the work

Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. If you have questions first, give us a call on 01277 525 020 or email the details over.

What we are called out for in Roehampton

On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is how unsuitable products and improvised details end up in compartment walls and later need putting right.

Things that typically lead to an enquiry:

  • Unsealed penetrations discovered above suspended ceilings
  • Damaged fire seals in risers and voids
  • Unsealed openings around new pipes and cables
  • Penetration schedules that need working through

Offices at parks like Chartwell Business Park (1.9 miles east of Roehampton) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.

Our contractor checklist

On site: what to expect

Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.

  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. 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.

Preparing the site

  • Tell us your opening times and when work is allowed
  • Confirm the product named in the specification
  • Share the asbestos register for older buildings

Advice

Maintenance after handover

Once the work is signed off, these steps help:

  • Have penetrations checked while they can still be seen
  • Treat an open penetration as a priority repair
  • Ask which product is in place before decorating
  • Include service cupboards in routine inspections

Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted.

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.

Common questions from Roehampton clients

Can you work on a hospital site such as Queen Mary's Hospital?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

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

Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Do you certify or sign off fire stopping?

No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. We work to the specification and the manufacturer’s installation guidance.

Will you come and look before quoting?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

What do you charge?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote.

Do you cover Roehampton?

Yes. Sites across Roehampton are covered, and the same phone number covers every area.

Do you seal openings left by new services?

Yes. Send the schedule or marked-up drawings and the specified product details for a fixed quote. We can follow the services contractor floor by floor keeping pace with the programme.

When to bring in a specialist

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
