Fire stopping across West Silvertown

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

How the job changes by surface

Risers and ceiling voids

Service risers and the voids above ceilings are where openings collect. Access to these areas is planned with you in advance.

Masonry and concrete

Block walls and concrete floors are common substrates for penetration seals. Dust and debris are cleared from the opening, so the sealant and any backing sit properly.

How we handle fire stopping in West Silvertown

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. If you are dealing with penetration schedules that need working through and unsealed openings around new pipes and cables, we can help. One point of contact handles commercial sealant work in West Silvertown from the first photos to the final walk-round, 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. We install what the designer or fire engineer has specified, and if you need records of the work, tell us 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.

Fire stopping in West Silvertown: the local picture

West Silvertown has a good number of hotels close by, all within 2 miles. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with the specified product. Fire stopping of openings and penetrations in England falls under 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. What we install is set by the specification, and it goes in to the tested detail.

Where a unit on an estate such as Greenshields Industrial Estate, less than half a mile south-west of West Silvertown, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. For a unit at a centre such as Brocklebank Retail Park, which lies south of West Silvertown, penetration seals are worth checking after each shop fit.

How a job runs

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For a job in West Silvertown, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we’ll schedule to suit.

  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 so the seal starts clean.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

Before we start on site

  • Send asbestos survey details if the building is pre-2000
  • Move anything stored against the joints
  • Have the specification and drawings to hand

Request a quote

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call the office on 01277 525 020 or email a schedule or drawings with what you know.

Leave it or put it right?

Fire stopping is a regular point raised at inspections and handover. Late discoveries can delay handover while openings are reopened and resealed. In West Silvertown, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

Why appoint us

  • Joints cleaned back to sound surfaces
  • CSCS-carded applicators
  • Specification-led, product-correct work
  • CHAS accredited

Read our cost guide and our accreditations and insurance.

When something else is needed

Honesty saves time and money. Fresh joints won’t solve:

  • Signing off or certifying a building’s fire stopping
  • Fire risk assessments, a job for a competent assessor
  • Deciding what a wall or floor needs, which belongs to the designer

If in doubt, speak to us on 01277 525 020 or use the quote form and we will say what we think.

Where we work in West Silvertown

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

Do you need fire stopping in West Silvertown?

Physical damage is another reason seals stop doing their job. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe and the opening isn’t always resealed.

It’s worth sending us details if you spot any of the following:

  • Old intumescent sealant that has split away
  • Unsealed openings around new pipes and cables
  • Open linear gaps along the top of fire-resisting walls
  • Builders’ foam or ordinary silicone in compartment walls

Theatres, wards and plant rooms at sites like Newham University Hospital (to the north of West Silvertown) all have compartment walls crossed by services.

What to look for in a quote

  • Will RAMS and insurance details be available?
  • Which product they’ll use, and why it suits the joint
  • The terms of the workmanship guarantee
  • Can the work be phased to keep areas open?

Questions to ask before you appoint anyone

How the quote is worked out

What shapes the price:

  • Phasing around occupants
  • Distance, for remote addresses
  • The site’s rules and procedures
  • The product specified

Pricing service penetrations depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

Before you send an enquiry

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • What the building is and how it’s used
  • Approximate linear metres or a joint schedule
  • Your programme or deadline
  • Specification clauses that apply

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.
