Fire stopping in Crabtree, done properly
Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail rather than guesswork. Site teams most often ask us about seals that don’t match their tested detail and seals disturbed by maintenance and left open, on small duct penetrations where the tested detail allows, pipe penetrations and linear gaps at wall heads. Facilities teams, main contractors and managing agents in Crabtree tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Smaller places such as Crabtree still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

When to call us in Crabtree
Mixing products or improvising a detail breaks the link with the test evidence. 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.
Look out for the following:
- Snag lists that include open service penetrations
- Improvised or mixed-product fire seals
- Hidden openings found during inspections
- Old intumescent sealant that has split away
In a school such as Newells Preparatory School, fire-rated sealant goes in around service penetrations where it is specified.

How a job runs
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence, and we clear our waste as we work. If others near Crabtree need work, visits can be combined. A fixed quote is given before anything starts.
- 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.
Before we start on site
- Tell us what induction or permit system the site runs
- Tell us which areas need to stay in use
- Let building users know which areas are affected

Advice
FAQs: Crabtree
Can you work at a site such as Brook Farm Business Park, by Crabtree?
Yes. Our area takes in Crabtree and its surroundings, with estates and business parks such as Brook Farm Business Park included. Photos and a short description are enough for a first look.
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Crabtree?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s 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.
Which sealant will you use?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, tell us and we will confirm them with the quote.
Penetration seals near Crabtree
Crabtree lies roughly 34 miles out from central London. 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. 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. Our part stays the same: the specified product, installed to its tested detail.
For a hotel such as South Lodge Hotel, less than half a mile to the north-west of Crabtree, penetration seals are worth checking after any refit or services upgrade. For a building such as Old Church House the Glebe, new heating or data runs are the usual reason penetrations need sealing.

What happens if it’s left?
Fire stopping is a regular point raised at inspections and handover. Finding unsealed or improvised openings late can hold up a programme, so earlier action pays back. Converted and older buildings near places like Crabtree tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Honest limits
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Writing the fire-stopping specification
- Walls or floors that aren’t fire-resisting to begin with
- Openings that need collars, wraps, batts or boards rather than sealant
If you’re not sure, just call 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.
What we seal
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Linear gaps at wall heads
- Pipe penetrations
- Cable penetrations
What the job involves on each 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.
Plastic pipes
Plastic waste pipes through slabs come up often. Whether sealant alone is acceptable depends entirely on the tested detail.
