Fire stopping for commercial buildings in Wraysbury
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, often unnoticed. We close the openings listed on your schedule, using the specified sealant and detail. We work on cable penetrations, small duct penetrations where the tested detail allows and service gaps in risers, and the usual reasons a site gets in touch are fire seals cut back for extra cables and never reinstated and openings left by services added after handover. One point of contact handles commercial sealant work in Wraysbury from the first photos to the final walk-round, whether it’s one building or several.
Around Wraysbury, penetration and linear seals tend to be one-building jobs. With the specification and photographs of the gaps, we can give a fixed quote and bring the right products.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Our process
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes anything from one day to a planned run of visits, depending on the number of seals and the access, and we clear our waste as we work. For a site in Wraysbury, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- Where the detail needs backing, it goes in at the stated depth.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- Completed areas are checked with you, with the records agreed when we quoted.
Before we start on site
- Share the asbestos register for older buildings
- Point out any areas we must not close
- Clear stock, furniture or equipment away from the joints

Common questions from Wraysbury clients
Is Portland Business Park, near Wraysbury, within your area?
Yes. Our area takes in Wraysbury and its surroundings, with estates and business parks such as Portland Business Park included. Send details of the unit and the work through our quote form for a quick quote.
Can you seal penetrations in a hotel in Wraysbury after a refit?
Yes. We install fire-rated and intumescent sealant where it is specified. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, let us know and we’ll send them with the quote.
Can the building stay open while you work?
Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.
How many days will you need on site?
It depends on the scope, though a typical visit typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. For bigger or phased jobs, we’ll set out a timescale with the quote.
Different surfaces, different methods
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, and we work within it.
Masonry and concrete
Many seals are made in blockwork, brickwork or concrete slabs. Dust and loose debris are cleared out of the opening, so the sealant and any backing sit properly.
Where services cross fire walls in Wraysbury
The area within 2 miles of Wraysbury holds several hotels. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with the specified product. Wraysbury is about 20 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.
At a healthcare site like Princess Margaret Hospital, which lies north-west of Wraysbury, new services through compartment walls are a constant, and each needs the specified seal. For a site team at a college like Strode's College, which lies south of Wraysbury, fire-rated sealing is best scheduled after the summer works.

Aftercare for building managers
For the best life from the joints:
- Have penetrations checked while they can still be seen
- Look above ceilings when tiles are lifted for other jobs
- Keep product data and details in the fire safety file
- Check with the data sheet before painting over fire sealant
After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.
A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, which saves guesswork.

Do you need fire stopping in Wraysbury?
Damage plays a part too. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped.
Typical triggers for a call:
- Unsealed penetrations discovered above suspended ceilings
- Unsealed openings around new pipes and cables
- Builders’ foam or ordinary silicone in compartment walls
- Fire seals cut back for extra cables and never reinstated
For a building at a site such as Portland Business Park, which lies north-west of Wraysbury, a check of penetration seals after each fit-out is good practice.
What your quote should include

Why it’s worth doing now in Wraysbury
Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.
