Fire stopping around Hook: how the place shapes the job
Hook has several hotels close by, all within 2 miles. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit 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 hotel such as The White Hart Hotel, which lies south-west of Hook, penetration seals are worth checking after any refit or services upgrade. For a building at a site such as Murrell Green Business Park (1 mile east of Hook), a check of penetration seals after each fit-out is good practice. Hospital estates such as Fleet Community Hospital, 4.7 miles east of Hook, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.
Hook is about 5 miles west of Fleet, in Hampshire. Anywhere in RG27, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. 723 places across Hampshire fall within our area, Hook among them. Reading is covered too, some 11 miles away.
If you need fire stopping in RG27, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee.

Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We hold no 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. Site teams most often ask us about unsealed penetrations discovered above suspended ceilings and open linear gaps along the top of fire-resisting walls, across linear gaps at wall heads, service gaps in risers and cable penetrations. For commercial sealant work in Hook, you deal with one contact from quote to sign-off, whether it’s one building or several.

Commercial clients in Hook
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules.
Your questions answered
Is Hook too far out for you?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Can you seal around new services in a hotel near Hook?
Yes, where the specification calls for fire-rated sealant. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Can you quote from photos?
That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs normally get a visit.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
How long does a typical visit take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
On site: what to expect
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Several jobs near Hook can be grouped on one trip. Tell us your site hours and we will plan around them.
- We ask for the product and detail your designer has specified.
- Openings are measured and grouped by detail.
- 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.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Preparing the site
- Tell us your opening times and when work is allowed
- Point out parking and an unloading spot
- Let building users know which areas are affected

Advice
Cost factors for service penetrations
Before we quote, we look at:
- How much there is to seal
- Which sealant the job calls for
- Whether the work must be split into stages
- Location, for remote and island sites
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
Before you send an enquiry
Diagnosis starts before we arrive. Let us know:
- Whether an asbestos survey exists
- Specification clauses that apply
- A wide shot and a close-up of the area
- What the building is and how it’s used
The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or speak to us on 01277 525 020 or use the quote form if you’d rather talk the job through.

What else we do in Hook
What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Reviewing a building’s overall fire safety
- Plastic pipes whose detail calls for a collar or wrap
- Construction that lacks the fire resistance the seal relies on
If in doubt, give us a call on 01277 525 020 or send photos by email and we will say what we think.
What we seal
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Service gaps in risers
- Pipe penetrations
- Cable penetrations
What the job involves on each surface
Cables and cable bundles
Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. The detail limits bundle size and the gaps between and around cables and we work within those limits.
Small ducts
Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Bigger ducts and fire-resisting ductwork are normally handled with other products, and we’ll say if that applies.
What happens if it’s left?
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. Putting it right is typically a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Small buildings around Hook suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
