Your questions answered
Is a smaller place like Hawthorn Hill outside your area?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
What happens to BS 476 references for fire stopping in Hawthorn Hill?
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.
Is your workmanship covered by a guarantee?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.
How long will the new sealant last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Is any job too small?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
How do we ask for a quote?
The quote form is the simplest route, though you can also give us a call on 01277 525 020 or email us. Include photos or drawings if you have them.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
How we handle fire stopping in Hawthorn Hill
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, speak to us on 01277 525 020 or email the details over with the schedule or marked-up drawings. Tell us what records you need and we’ll confirm with the quote. Site teams most often ask us about expanding foam used as fire stopping and fire seals cut back for extra cables and never reinstated, across service gaps in risers, pipe penetrations and small duct penetrations where the tested detail allows. A single leaking joint is often how a building in Hawthorn Hill 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.
For a smaller site near Hawthorn Hill, we plan to do all the penetrations in one go, with the specification and photographs sent in advance. 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: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Looking after the joints
Cleaning and maintenance staff play a part too. Pass these on to them:
- Arrange inspection before areas are covered up
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Keep product data and details in the fire safety file
- Check risers and ceiling voids after each round of works
Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t, and the data sheet says which.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job; found late, it can be one of many.
From enquiry to sign-off
Site rules come first: signing in, inductions and any permit to work. 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. Rural sites near Hawthorn Hill may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- The specification and schedule come first, so we know which details apply.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out so the seal starts clean.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
Preparing the site
- Tell us which areas need to stay in use
- Share the asbestos register for older buildings
- Clear stock, furniture or equipment away from the joints
Getting a fixed quote
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to call 01277 525 020 or email the details over.
Advice
Doing it in-house
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Fire stopping around Hawthorn Hill: how the place shapes the job
At about 28 miles from central London, Hawthorn Hill is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. Fire stopping of openings and penetrations in England falls under Approved Document B. 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.
For a hospital such as Heatherwood Hospital, 4 miles to the south-east of Hawthorn Hill, penetration sealing is normally phased ward by ward, with infection-control rules agreed first. For a school such as Holyport College, penetration sealing fits best at the end of the summer works.
Hawthorn Hill is about 3 miles north of Bracknell, in Windsor and Maidenhead. We cover Hawthorn Hill, with the same fixed quotes and 12-month guarantee as everywhere else. We work across 60 places in Windsor and Maidenhead, large and small. There’s a separate page for Reading, about 10 miles away.

When something else is needed
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:
- Large openings beyond what any sealant detail covers
- Issuing fire ratings or certificates for seals
- Gaps in walls that were never built as compartment walls
If you are not sure, just ring 01277 525 020 or email a schedule or drawings and we will give you a straight answer.
Surfaces we seal
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Cable penetrations
- Service gaps in risers
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
When to call us in Hawthorn Hill
When a seal departs from its tested detail, the evidence no longer covers it. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are the usual culprits.
If one of these sounds familiar, it’s time for a closer look:
- Fire-stopping items raised at inspection or handover
- Old intumescent sealant that has split away
- Damaged fire seals in risers and voids
- Seals that don’t match their tested detail
At a college such as Newbold College of Higher Education, 3 miles south-west of Hawthorn Hill, checking penetration seals after summer M&E works is good practice.
What your quote should include
- How the joint faces will be prepared and primed
- Their approach to joint depth and backing
- Their public liability cover
- How long is the guarantee, and what does it include?

Different surfaces, different methods
Plastic pipes
Plastic pipes soften and collapse in a fire. Some intumescent sealants are tested on smaller plastic pipes. We check the pipe material and diameter against the detail before we start.
Cables and cable bundles
Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. Bundle size, cable type and the space between cables all matter, so we check before sealing.
