Fire stopping in Hampstead Norreys
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, matching the product and detail it names. Where there isn’t one, the designer or fire engineer needs to set one first. If you are dealing with old intumescent sealant that has split away and seals disturbed by maintenance and left open, we can help. A single leaking joint is often how a building in Hampstead Norreys first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Smaller places such as Hampstead Norreys still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Owners, agents and contractors
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
How the quote is worked out
Quotes vary with the job. Expect it to depend on:
- Access and working height
- The site’s rules and procedures
- Specialist products, such as fire-rated or hygienic sealants
- Removal of failed or old sealant
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Before you send an enquiry
It doesn’t need to be a full survey. These details are enough to start:
- The postcode of the building
- Asbestos survey details if the building is older
- Any dates the work must fit around
- The type of building and who uses it
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 photos and a few notes.
Diagnose, treat, sign off
Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. If others near Hampstead Norreys need work, visits can be combined. A fixed quote is given before anything starts.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- Where the detail needs backing, it goes in at the stated depth.
- 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.
Preparing the site
- Move anything stored against the joints
- Share the asbestos register for older buildings
- Let building users know which areas are affected
Ask for a quote
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or email a schedule or drawings.

What the job involves on each surface
Plastic pipes
Plastic pipes soften and collapse in a fire. Some intumescent sealants are tested on smaller plastic pipes. We confirm material and size first and tell you if sealant isn’t the right product.
Metal pipes
Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on, so we check each one.
What else we do in Hampstead Norreys
Looking after the joints
Problems stay small when the joints are checked regularly. In particular:
- Treat an open penetration as a priority repair
- Keep general-purpose fillers away from compartment walls
- Get seals inspected before ceilings and boxing close
- Put resealing into every M&E and fit-out package
Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Look for cracks, unsealed new cables and gaps that have been enlarged.
Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small compared with dozens found at once.
Compartment walls and floors in Hampstead Norreys
In England, Approved Document B covers fire stopping of openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. At about 49 miles from central London, Hampstead Norreys is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product.
At a healthcare site like West Berkshire Community Hospital, which lies south-west of Hampstead Norreys, new services through compartment walls are a constant, and each needs the specified seal. Older community buildings such as Church of St Mary that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
Hampstead Norreys is about 6 miles north of Thatcham, in West Berkshire. Across the RG18 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed.

What we’re called out for in Hampstead Norreys
Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it, so it has to come out.
Clients normally get in touch after noticing something like this:
- Open linear gaps along the top of fire-resisting walls
- Snag lists that include open service penetrations
- Builders’ foam or ordinary silicone in compartment walls
- Openings found when ceilings come down for a refit
For a school such as Hampstead Norreys C.E. Primary School, penetration sealing fits best at the end of the summer works.

Hampstead Norreys: questions and answers
What happens to BS 476 references for fire stopping in Hampstead Norreys?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
