Fire stopping in Brentwood
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
How we handle fire stopping in Brentwood
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. With no specification in place, the first step sits with your designer or fire engineer, not with us. We work on cable penetrations, linear gaps at wall heads and joints between fire-resisting walls and floors, and the usual reasons a site gets in touch are openings found when ceilings come down for a refit and unsealed openings around new pipes and cables. Facilities teams, main contractors and managing agents in Brentwood tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
In a town such as Brentwood, fire-rated sealing is often needed in schools, surgeries, care homes, offices and flats above shops. Whenever new services go through those walls, the gaps need sealing with the specified product.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.
Surface by surface
Linear joints
Head-of-wall gaps, slab edges and wall junctions are linear joints. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed.
Drylining partitions
Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do, and the detail may call for board patching or another product.
Signs you need fire stopping in Brentwood
When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are what we find most often.
It’s worth sending us details if you spot any of the following:
- Fire seals cut back for extra cables and never reinstated
- Old intumescent sealant that has split away
- Improvised or mixed-product fire seals
- Fire-stopping items raised at inspection or handover
On a hospital site such as Nuffield Hospital (less than half a mile south-east of Brentwood), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
Questions to ask before you book
- Whether primer will be used where the manufacturer specifies it
- Which product they’ll use, and why it suits the joint
- How the existing material will be dealt with
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
Our process
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. If you have more than one building in Brentwood, they can often be done on the same visit, with one quote covering them. Give us your access times and we’ll fit the work in.
- We ask for the product and detail your designer has specified.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- Mineral wool or other backing is fitted where required.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
What we need from you
- Tell us what induction or permit system the site runs
- Tell us your opening times and when work is allowed
- Send asbestos survey details if the building is pre-2000
Getting a fixed quote
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.

Looking after the joints
A few simple habits keep the new joints working:
- Treat an open penetration as a priority repair
- Agree the fire-stopping specification before services go in
- Include service cupboards in routine inspections
- Put resealing into every M&E and fit-out package
Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.
A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.
Your questions answered
What does the BS 476 change mean for fire-rated sealant in Brentwood?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Can you seal penetrations in a hotel in Brentwood after a refit?
Yes, where fire-rated sealant is the specified product. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.
Can staff carry on working while you are here?
Typically, yes. Phased work can be planned so areas stay in use.
Can one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
When can you be on site?
Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
When is resealing likely to be due?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Fire stopping around Brentwood: how the place shapes the job
A number of hotels sit less than 2 miles from Brentwood. In hotels, bedroom and corridor walls are typically fire-resisting, so services added in a refit need sealing with the specified product. Central London is about 19 miles from Brentwood. Office refits around the commuter belt bring new cabling through fire-resisting walls.
Office fit-outs on sites such as Warley Hill Business Park, 1.5 miles to the south of Brentwood, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it. Hotels such as Brentwood Hotel, 0.8 miles to the south of Brentwood, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.
