Fire stopping in Crowdhill, done properly
Most of our fire stopping work happens after the building is up. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, and they are easy to forget. We close the openings listed on your schedule, using the specified sealant and detail. We work on joints between fire-resisting walls and floors, pipe penetrations and linear gaps at wall heads, and the failures we are asked to look at most are fire-rated sealant that has cracked or shrunk back and openings left by services added after handover. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Crowdhill, that means joint design, primers and backing rod as standard.
Smaller places such as Crowdhill 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.
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 are upfront about that.

What we can’t put right
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Construction that lacks the fire resistance the seal relies on
- Fire doors, dampers or other fire safety equipment
- Openings that need collars, wraps, batts or boards rather than sealant
If you’re not sure, just call the office on 01277 525 020 or email the details over and we’ll give you a straight answer.
Surfaces we seal
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Cable penetrations
Our process
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Rural sites near Crowdhill may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- On site, each opening is checked against the tested detail it is meant to follow.
- Unsuitable fillers and loose debris are taken out of each opening.
- We fit the backing the detail asks for, to the stated depth.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
Getting the site ready
- Arrange parking or a loading space
- Confirm the product named in the specification
- Move anything stored against the joints

Advice
Work for main contractors and building owners
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Where services cross fire walls in Crowdhill
Crowdhill is about 63 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls, and the gaps need sealing with the specified product. For England, the fire stopping of penetrations is dealt with in Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.
For a hospital such as Wessex Hospital, 2.8 miles north-west of Crowdhill, penetration sealing is typically phased ward by ward, with infection-control rules agreed first. Office fit-outs on sites such as Vicarage Farm Business Park, under half a mile south-east of Crowdhill, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.
Crowdhill is about 2 miles north-east of Eastleigh, in Hampshire. Crowdhill sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Crowdhill is one of 723 places in Hampshire on our list. For work in that direction, see our Southampton page, about 6 miles away.

Why deal with it now?
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. One visit to deal with every failing joint makes more sense than several trips to a place like Crowdhill. Send photos of each area and we will quote for the lot.
The price depends on the quantity of joints, what has to come out first and the access. Call for a quote once you have the details.

FAQs: Crowdhill
Could you schedule work at a campus like Eastleigh College - Desborough Campus for the vacation?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Is Vicarage Farm Business Park, near Crowdhill, within your area?
Yes. Estates, retail parks and business parks around Crowdhill, Vicarage Farm Business Park among them, are all within reach. Photos and a short description are enough for a first look.
Is sealant suitable for all service openings?
No. Each fire-rated sealant is tested for particular services, gap sizes and substrates. Outside that, a different product is needed.
Do you need to see the site first?
It depends on the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs normally get a visit.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Can you send site paperwork?
Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.
How long does a job like this take?
It depends on the scope, but the work normally takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. For bigger or phased jobs, we will set out a timescale with the quote.

What we’re called out for in Crowdhill
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.
Look out for the following:
- Improvised or mixed-product fire seals
- Builders’ foam or ordinary silicone in compartment walls
- Old intumescent sealant that has split away
- Head-of-wall gaps with no fire seal
In a retail centre such as Cannons Retail Park, 2.9 miles to the west of Crowdhill, any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail.
Comparing quotes
- Which product they’ll use, and why it suits the joint
- Whether old or failed sealant will be cut out, not overlaid
- Proof of insurance
- Do they follow the manufacturer’s priming guidance?
Aftercare for building managers
Your facilities or cleaning team can help the joints last. Share these points with them:
- Settle who seals which penetrations at the start of a project
- Don’t let anyone top up a fire seal with the wrong product
- Have penetrations checked while they can still be seen
- Make fire stopping part of every scope that crosses a fire-resisting wall
Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original, or a new specification from the designer.
Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts.
