Fire stopping in Crawley
On a fit-out or refurbishment, we follow the services contractors floor by floor. We work from your penetration schedule or marked-up drawings. Tell us what records you need and we will confirm with the quote. If you are dealing with penetration schedules that need working through and hidden openings found during inspections, we can help. For commercial sealant work in Crawley, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
A job near Crawley is typically planned around one visit, with the specification and photographs sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.
Our workmanship is guaranteed for 12 months, in Crawley as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Our process
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes a single visit for a short list of penetrations, or a phased programme for a whole building, and we clear our waste as we work. Rural sites near Crawley may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- Each opening is checked for wall or floor type, service, gap and depth.
- Foam, ordinary sealant and debris come out first.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Before we start on site
- Confirm the product named in the specification
- Share the asbestos register for older buildings
- Arrange parking or a loading space
Quotes
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Places near Crawley

Compartment walls and floors in Crawley
Central London is about 62 miles from Crawley. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. Our part stays the same: the specified product, installed to its tested detail.
Where a unit on an estate such as Beeches Industrial Park, which lies south-east of Crawley, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. For a site team at a college like Sparsholt College Hampshire, which lies south of Crawley, fire-rated sealing is best scheduled after the summer works. For a building such as Church of St Mary, new heating or data runs are the usual reason penetrations need sealing.
Crawley is about 5 miles north-west of Winchester, in Hampshire.

- Reviewing a building’s overall fire safety
- Writing the fire-stopping specification
- Large openings beyond what any sealant detail covers

Where we work in Crawley
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Cable penetrations
Different surfaces, different methods
Metal pipes
Sealant details often cover copper and steel pipework. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail, so we check each one.
Risers and ceiling voids
Service risers and the voids above ceilings are where openings collect. Access is often tight, so we agree it with you in advance.
For managing agents and facilities managers
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Common questions from Crawley clients
Is Crawley off your patch?
No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Crawley?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Can you handle several sites?
Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also ring 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
Doing it in-house
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Why it’s worth doing now in Crawley
Open penetrations multiply: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable. Around Crawley, it’s better to renew all the failing joints at once. Send photos of each area and we will quote for the lot.
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
