Fire stopping in Rushmoor, done properly
A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, and they are easy to forget. We close the openings listed on your schedule, using the specified sealant and detail. We work on linear gaps at wall heads, joints between fire-resisting walls and floors and cable penetrations, and the usual reasons a site gets in touch are fire-rated sealant that has cracked or shrunk back and service penetrations left open after M&E works. A single leaking joint is often how a building in Rushmoor first comes to us: we look at the rest while we’re there and tell you what we find.
For a smaller site near Rushmoor, we plan to do all the penetrations in one go, with the specification and photos sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Should maintenance staff do it?
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
Why deal with it now?
An unsealed opening affects more than fire safety: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first and the building feels the difference. One visit to deal with every failing joint makes more sense than several trips to a place like Rushmoor. Photos of every joint help us quote for the whole job.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

When it isn’t the sealant
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Openings that need collars, wraps, batts or boards rather than sealant
- Reviewing a building’s overall fire safety
- Designing or specifying fire stopping, which sits with the designer or fire engineer
If you are not sure, just phone 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.
Surfaces we seal

From enquiry to sign-off
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself usually taking longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Smaller jobs around Rushmoor can be grouped with others nearby. You will have a fixed quote before work starts.
- We start with your penetration schedule, drawings or specification.
- We plan the sequence of floors, risers and voids with you.

Advice
Fire stopping around Rushmoor: what changes locally
In England, Approved Document B covers fire stopping of openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. At about 37 miles from central London, Rushmoor is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls.
For a hospital such as Haslemere and District Hospital, 4.9 miles to the south of Rushmoor, penetration sealing is usually phased ward by ward, with infection-control rules agreed first.
Rushmoor is about 4 miles south-east of Farnham, in Surrey. Anywhere in GU10, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Rushmoor is one of 379 places we cover in Surrey for service penetrations. For work in that direction, see our Reading page, about 22 miles away.
Anyone looking for fire stopping in GU10 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. Buildings on Sandy Lane, Lowicks Road and Tilford Road are within our area for service penetrations. If your building is just outside Rushmoor, we cover Tilford Common (1 mile north), Pitch Place (1 mile south-east), Crosswater (1 mile south-west), Thursley (2 miles east) and Green Cross (2 miles south). Nearby towns on our patch include Guildford (10 miles north-east), Woking (13 miles north-east), Camberley (12 miles north), Farnham (4 miles north-west), Frimley (11 miles north) and Haslemere (5 miles south).

Do you need fire stopping in Rushmoor?
Most open service penetrations are left by later work. New cabling, rerouted pipework or a data route drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.
Typical triggers for a call:
- Penetration schedules that need working through
- Old intumescent sealant that has split away
- Builders’ foam or ordinary silicone in compartment walls
- Unsealed joints where partitions meet the slab
Residences at universities like University for the Creative Arts, 4.7 miles north-west of Rushmoor, have compartment walls that must be resealed whenever services change.

Common questions from Rushmoor clients
Could you schedule work at a campus like University for the Creative Arts for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
What does the BS 476 change mean for fire-rated sealant in Rushmoor?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Can the building stay open while you work?
Usually, yes. Phased work can be planned so areas stay in use.
Can you quote from photos?
It depends on the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs typically get a visit.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Keeping the joints sound
A few simple habits keep the new joints working:
- Have penetrations checked while they can still be seen
- Ask the designer to confirm details early on refits
- Keep general-purpose fillers away from compartment walls
- Put resealing into every M&E and fit-out package
Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Look for cracks, unsealed new cables and gaps that have been enlarged.
Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.
