Where services cross fire walls in Sulham
Sulham 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. Our part stays the same: the specified product, installed to its tested detail.
Shop fits in centres such as Reading Retail Park, 2.6 miles to the east of Sulham, can bring new services through fire-resisting walls between units, which then need the specified seal. Campus buildings at universities such as University of Reading, 5 miles to the east of Sulham, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified.
Sulham is about 4 miles west of Reading, in West Berkshire. Anywhere in RG8, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Our West Berkshire coverage takes in 140 places, from busy centres to rural villages.
Postcode districts covered here: RG8 for service penetrations. If your site is on Sulham Lane and Nunhide Lane or close by, send details and we will quote for service penetrations. We also cover Tidmarsh (1 mile west), Little Heath (1 mile south-east), Pangbourne (1 mile north-west), Purley on Thames (1 mile north-east) and Tilehurst (2 miles east). Further afield, our area takes in Newbury (12 miles south-west), Thatcham (9 miles south-west), Burghfield Common (5 miles south), Speenhamland (12 miles west), Fords Farm (3 miles south-east) and Shaw (11 miles west).

Fire stopping in Sulham, done properly
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. We work from your penetration schedule or marked-up drawings. Tell us what records you need and we will confirm with the quote. Site teams most often ask us about unsealed penetrations discovered above suspended ceilings and fire seals cut back for extra cables and never reinstated, on pipe penetrations, service gaps in risers and small duct penetrations where the tested detail allows. A single leaking joint is often how a building in Sulham first comes to us: we look at the rest while we are there and tell you what we find.
Around smaller places like Sulham, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

What happens if it’s left?
Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. The specified fire seal closes the gap for all of these and the building feels the difference. For buildings around smaller places like Sulham, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

- Specification-led, product-correct work
- Clear, fixed quotes

What we can’t put right
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Gaps in walls that were never built as compartment walls
- Writing the fire-stopping specification
- Reviewing a building’s overall fire safety
If you’re not sure, just call the office on 01277 525 020 or email a schedule or drawings and we will give you a straight answer.
What we seal
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Pipe penetrations
- Cable penetrations
- Service gaps in risers
- Linear gaps at wall heads

Signs you need fire stopping in Sulham
When a seal departs from its tested detail, the evidence no longer covers it. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are what we find most often.
Site and facilities staff are often the first to spot these:
- Fire-stopping items raised at inspection or handover
- Head-of-wall gaps with no fire seal
- Old intumescent sealant that has split away
- Damaged fire seals in risers and voids
For a building at a site such as Turnhams Green Business Park, 1.7 miles south of Sulham, a check of penetration seals after each fit-out is good practice.
Before you book anyone
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How the joint faces will be prepared and primed
- What the guarantee covers, and for how long
- Can the work be phased to keep areas open?
When to bring in a specialist
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Redoing a failed joint typically costs more than getting it right at the outset, 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.
Diagnose, treat, sign off
Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. If others near Sulham need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.
- First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- We fit the backing the detail asks for, to the stated depth.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
Before we start on site
- Explain the parking and delivery arrangements
- Tell us your opening times and when work is allowed
- Send any specification or drawings in advance

Questions about Sulham
What does the BS 476 change mean for fire-rated sealant in Sulham?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Do you cover business parks and estates near Sulham, such as Turnhams Green Business Park?
Yes, sites like Turnhams Green Business Park are within our area, along with the rest of Sulham. 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 take on small jobs?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Is Sulham in your area?
Yes. Sulham is in our area and the rest of West Berkshire, within our coverage of Greater London, South East England and Scotland. For a quote, ring 01277 525 020 or email a schedule or drawings.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
How long does a typical visit take?
It depends on the scope, though a typical visit typically takes a single visit for a short list of penetrations, or a phased programme for a whole building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- File the specified details where the next contractor can find them
- Settle who seals which penetrations at the start of a project
- Leave fire sealant to cure fully before covering it
- Include service cupboards in routine inspections
Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original unless the designer specifies otherwise.
A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate, and it helps at inspections.
