Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
How a job runs
Tell us your site hours and access windows and we will plan around them. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Smaller jobs around Crowell Hill can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned so the seal starts clean.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Preparing the site
- Share your working hours and any access restrictions
- Tell staff and tenants when we’ll be in
- Have the specification and drawings to hand

Fire stopping in Crowell Hill
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate, and we won’t pretend otherwise. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. We work on cable penetrations, small duct penetrations where the tested detail allows and service gaps in risers, and the failures we are asked to look at most are old intumescent sealant that has split away and fire seals cut back for extra cables and never reinstated. Whoever orders the work in Crowell Hill, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
For a smaller site near Crowell Hill, we plan to do all the penetrations in one go, so send the specification and photographs first. Design and sign-off belong to the designer or building control; we install what’s specified.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Doing it in-house
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Service penetrations in Crowell Hill buildings
Central London is about 37 miles from Crowell Hill. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product. In England, Approved Document B covers fire stopping of openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.
For a unit at a site such as Junction 5 Bates Industrial Estate, which lies south of Crowell Hill, new power or data runs between office and warehouse can breach a compartment wall. Hotels such as Kings Hotel (to the south of Crowell Hill) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.
Crowell Hill is about 5 miles south-east of Thame, in Oxfordshire. Our applicators travel to Crowell Hill for work on service penetrations. 423 places across Oxfordshire fall within our area, Crowell Hill among them. Oxford is covered too, some 15 miles away.

If your building is just outside Crowell Hill, we cover Crowell (1 mile north-west), Kingston Blount (1 mile north-west), Oakley (1 mile north-west), Aston Rowant (2 miles west) and Lewknor (3 miles west). Bigger towns within reach include Oxford (15 miles west), Didcot (15 miles west), Thame (5 miles north-west), Henley-on-Thames (10 miles south), Benson (10 miles south-west) and Headington Quarry (14 miles north-west).
Around Crowell Hill

Why it’s worth doing now in Crowell Hill
Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme. Halls, stores and units around places like Crowell Hill may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Honest limits
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Writing the fire-stopping specification
- Large openings beyond what any sealant detail covers
- Walls or floors that aren’t fire-resisting to begin with
If in doubt, speak to us on 01277 525 020 or email the details over and we will say what we think before you book.
Joints and surfaces we work on
- Service gaps in risers
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Pipe penetrations
- Joints between fire-resisting walls and floors
Common problems we fix in Crowell Hill
Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. The opening looks sealed but has no fire test evidence behind it and has to be removed.
These are often picked up first by site or facilities staff:
- Head-of-wall gaps with no fire seal
- Seals that don’t match their tested detail
- Openings left by services added after handover
- Snag lists that include open service penetrations
In a building such as Church of the Nativity of the Blessed Virgin Mary, any service penetration through a fire-resisting wall should be sealed to the specified detail.

- Their public liability cover
- Which product they’ll use, and why it suits the joint
- Whether old or failed sealant will be cut out, not overlaid

What else we do in Crowell Hill
What the job involves on each surface
Cables and cable bundles
Single cables and small bundles are often within a fire-rated sealant’s tested detail. Bundle size, cable type and the space between cables all matter and we work within those limits.
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest against the detail’s limits.
Crowell Hill: questions and answers
Is hospital work, at somewhere like Thame Community Hospital, something you do?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
Does your area include sites such as Junction 5 Bates Industrial Estate, near Crowell Hill?
Yes. Estates, retail parks and business parks around Crowell Hill, Junction 5 Bates Industrial Estate among them, are all within reach. To start, just call the office on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Do you have public liability insurance?

How do we ask for a quote?
You can use the quote form on this site; alternatively, call 01277 525 020 or email a schedule or drawings. Include photos or drawings if you have them.
Which standards are fire seals tested to?
In short, BS EN 1366-3 and 1366-4 are the fire tests and BS EN 13501-2 is how results are classified. An EI 60 seal kept its integrity and insulation for 60 minutes as tested; installing to the detail is what carries that across to site.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Can you send site paperwork?
Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.
