Fire stopping in Maidenhead, done properly
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. If the detail calls for something other than sealant, we say so rather than force sealant into it. Site teams most often ask us about service penetrations left open after M&E works and unsealed joints where partitions meet the slab, on linear gaps at wall heads, small duct penetrations where the tested detail allows and cable penetrations. One point of contact handles commercial sealant work in Maidenhead from the first photos to the final walk-round, for single jobs and planned programmes alike.
Towns the size of Maidenhead have plenty of buildings with compartment walls: schools, care homes, surgeries, offices and blocks of flats. Whenever new services go through those walls, the gaps need sealing with the specified product.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Signs you need fire stopping in Maidenhead
Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it.
Things that typically lead to an enquiry:
- Fire sealant pulled out of the opening
- Fire-stopping items raised at inspection or handover
- Unsealed openings around new pipes and cables
- Improvised or mixed-product fire seals
Hotels such as Bear Hotel, 0.6 miles to the east of Maidenhead, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.
What your quote should include
- The named product and why it was chosen
- How long is the guarantee, and what does it include?
- What level of public liability insurance do they hold?
- Will failed sealant be removed rather than covered?
What the job involves on each surface
Cables and cable bundles
New data and power cables are the most common breach we see. We reseal around them to the specified detail, and any bundle too large for sealant alone is flagged.
Drylining partitions
Plasterboard partitions are tested as a specific construction. We check that the product’s detail covers that partition type and board thickness before sealing.
Diagnose, treat, sign off
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Town-centre premises in Maidenhead may have limited parking, so tell us what’s nearby. Industrial and business units normally have yard or car park space.
- First we go through the drawings, schedule or specification for the seals.
- On site, each opening is checked against the tested detail it is meant to follow.
- 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.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
What we need from you
- For older buildings, check the asbestos register before work
- Share your working hours and any access restrictions
- Clear stock, furniture or equipment away from the joints

Why it’s worth doing now in Maidenhead
Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first. For businesses and landlords in Maidenhead, a tidy, sound joint also matters for appearance. Fresh sealant makes a building look maintained.
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

Where services cross fire walls in Maidenhead
Plenty of hotels sit less than 2 miles from Maidenhead. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail. Maidenhead is about 27 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal.
Schools such as Claires Court Schools often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. Wherever services are added at a hospital such as St Mark's Hospital (to the north-west of Maidenhead) the compartment line has to be made good with the specified product.

Doing it in-house
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
After the work
Problems stay small when the joints are checked regularly. In particular:
- Flag new cables with no seal around them
- Don’t let anyone top up a fire seal with the wrong product
- Get seals inspected before ceilings and boxing close
- Brief every trade that openings they make must be sealed
Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.
On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned.
Common questions from Maidenhead clients
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Maidenhead?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is 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 take on work at healthcare sites like St Mark's Hospital?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
How much does the work cost?
Every job gets its own fixed quote. For yours, phone 01277 525 020 or send details through our quote form with a description of the work.
What happens if old sealant might contain asbestos?
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 if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Do you guarantee your work?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.
Can staff carry on working while you are here?
In the majority of cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.
