Fire stopping for commercial buildings in Broomershill

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate, and we won’t pretend otherwise. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. We work on linear gaps at wall heads, service gaps in risers and pipe penetrations, and the failures we are asked to look at most are builders’ foam or ordinary silicone in compartment walls and improvised or mixed-product fire seals. Looking for mastic applicators who cover Broomershill? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

A job near Broomershill is usually planned around one visit, so send the specification and photos first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

What happens if it’s left?

An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product. Converted and older buildings near places like Broomershill tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Why us?

  • Clear, fixed quotes
  • Over 20 years of commercial sealing
  • Specification-led, product-correct work
  • Old sealant cut out, never sealed over

For managing agents and facilities managers

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Broomershill can sit alongside others in a wider programme.

Looking after the joints

Keep the joints in good shape with a few simple steps:

  • Arrange inspection before areas are covered up
  • Record which product was used where
  • Check with the data sheet before painting over fire sealant
  • Ask the designer to confirm details early on refits

After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.

Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:

  • Plastic pipes whose detail calls for a collar or wrap
  • Fire doors, dampers or other fire safety equipment
  • Writing the fire-stopping specification

If you are not sure, just call 01277 525 020 or use the quote form and we’ll give you a straight answer.

Joints and surfaces we work on

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

Questions about Broomershill

What does the BS 476 change mean for fire-rated sealant in Broomershill?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

Is Broomershill too small for you to travel to?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

How much does the work cost?

Every job gets its own fixed quote. For yours, call 01277 525 020 or email the details over.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Do you offer coloured sealant?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Is it fine to apply new sealant on top of old?

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Cost factors for service penetrations

Your fixed quote is built from the real scope. It allows for:

  • Any access equipment needed
  • Removal of failed or old sealant
  • Location, for remote and island sites
  • Phasing around occupants

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

What to include in your enquiry

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • The asbestos register, for older buildings
  • Access details, including height
  • Photos of the joints, close up and from further back
  • Specification clauses that apply

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

On site: what to expect

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For work around Broomershill, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  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. Foam, ordinary sealant and debris come out.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

Before we start on site

  • Tell staff and tenants when we’ll be in
  • Have the specification and drawings to hand
  • Arrange parking or a loading space

Service penetrations in Broomershill buildings

Approved Document B is the English guidance that covers fire stopping around 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. Either way, we install the specified product to its tested detail. Broomershill lies roughly 41 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal.

Colleges such as Brinsbury College (to the north of Broomershill) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. Office fit-outs on sites such as Broomers Hill Business Park (to the north of Broomershill) add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.
