Fire stopping across Upminster Bridge

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

What we can’t put right

Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:

  • Fire risk assessments, a job for a competent assessor
  • Deciding what a wall or floor needs, which belongs to the designer
  • Large openings beyond what any sealant detail covers

If in doubt, give us a call on 01277 525 020 or send details through our quote form and we’ll say what we think.

Where we work in Upminster Bridge

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

About our fire stopping in Upminster Bridge

A fire-rated sealant is only one part of a tested system: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and raise it with you if it falls outside. If you have seals that don’t match their tested detail and unsealed penetrations discovered above suspended ceilings, we can help, on linear gaps at wall heads, small duct penetrations where the tested detail allows and cable penetrations alike. Facilities teams, main contractors and managing agents in Upminster Bridge tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

In London, higher-risk residential buildings under the Building Safety Act bring extra scrutiny of fire-stopping records. Our part is installing the specified fire-rated sealant; tell us what records you need and we will confirm with the quote.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

For managing agents and facilities managers

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Upminster Bridge can sit alongside others in a wider programme across Greater London.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

Service penetrations in Upminster Bridge buildings

For England, the fire stopping of penetrations is dealt with in Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. London’s office and residential buildings are refitted constantly, and each round of cabling or pipework can leave open penetrations. We seal to the specification and the product’s tested detail, working within the building’s permits.

In a building such as Church of St Laurence, any service penetration through a fire-resisting wall should be sealed to the specified detail. Hotels like Devonshire Hotel, 0.8 miles west of Upminster Bridge, are refurbished in phases, and each phase can open up compartment walls. For a site team at a college like New City College, less than half a mile north-west of Upminster Bridge, fire-rated sealing is best scheduled after the summer works.

Upminster Bridge is about 3 miles south-east of Romford, in Greater London. Any commercial site in Upminster Bridge is covered. We work across 764 places in Greater London. For work in that direction, see our London page.

Commercial sites across RM14, RM11 and RM12 are covered for service penetrations. We cover commercial and managed buildings on Holme Road, Hacton Lane and Lime Avenue. Just outside Upminster Bridge, we also work in Upminster (1 mile east), Hornchurch (1 mile west), Emerson Park (1 mile north), Cranham (1 mile east) and Hacton (1 mile south). Further afield, our area takes in London (15 miles west), Shoreditch (14 miles west), Walthamstow (11 miles west), Hoxton (14 miles west), Whitechapel (14 miles west) and Orpington (13 miles south-west).

From enquiry to sign-off

We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. All of Greater London is in the ULEZ, and kerbside space in Upminster Bridge can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

  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.

Before we start on site

  • Agree which areas must stay open
  • Send your site hours and access windows
  • Tell us what induction or permit system the site runs

Advice

General trades versus a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Why deal with it now?

Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first and the building feels the difference. 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.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What you get with us

After the work

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Ask the designer to confirm details early on refits
  • Brief every trade that openings they make must be sealed
  • Keep general-purpose fillers away from compartment walls
  • Check with the data sheet before painting over fire sealant

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

The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open.

Common questions from Upminster Bridge clients

Can you cope with the access rules in a London building?

Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough

Could you schedule work at a campus like New City College for the vacation?

Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Can you quote from photos?

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

Will you quote for a small job?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day.

Do you seal openings left by new services?

Yes. Send the schedule or marked-up drawings and the specified product details. Work can run area by area behind the M&E trades so areas aren’t left open.
