Fire stopping for businesses in Bisham
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Our process
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work normally takes a single visit for a short list of penetrations, or a phased programme for a whole building. For work around Bisham, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.
- We ask for the product and detail your designer has specified.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- 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.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Before we start on site
- For older buildings, check the asbestos register before work
- Tell staff and tenants when we’ll be in
- Clear stock, furniture or equipment away from the joints

About our fire stopping in Bisham
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 joints where partitions meet the slab and fire-stopping items raised at inspection or handover, across service gaps in risers, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors. Whoever orders the work in Bisham, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
Around smaller places like Bisham, 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.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Fire stopping around Bisham: what changes locally
Approved Document B is the English guidance that covers fire stopping around 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. Either way, we install the specified product to its tested detail. A good number of hotels sit less than 2 miles from Bisham. In hotels, bedroom and corridor walls are typically fire-resisting, so services added in a refit need sealing with the specified product.
For a building at a site such as Globe Business Park (1.2 miles north-east of Bisham), a check of penetration seals after each fit-out is good practice. On a hospital site such as Marlow Community Hospital, 1.1 miles north of Bisham, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
Bisham is about 1 mile south of Marlow, in Windsor and Maidenhead. We cover Bisham and the rest of Windsor and Maidenhead, with the same fixed quotes and 12-month guarantee as everywhere else. Bisham is one of 60 places in Windsor and Maidenhead on our list for service penetrations. There’s a separate page for Reading, roughly 11 miles from Bisham.
Work on service penetrations is covered throughout SL7, whatever the building. If your site is on Bisham Court, Marlow Road and Vansittart Road or close by, we can quote for service penetrations. Nearby places we also cover include Temple (1 mile south-west), Marlow (1 mile north), Cookham Dean (1 mile east), Pinkneys Green (2 miles south) and Cookham (2 miles east). Bigger towns within reach include Maidenhead (3 miles south-east), Windsor (8 miles south-east), Boyn Hill (4 miles south-east), Dedworth (8 miles south-east), Broomhall (13 miles south-east) and South Ascot (12 miles south).

When to call us in Bisham
Mixing products or improvising a detail breaks the link with the test evidence. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are the usual culprits.
Most enquiries start with one or more of the following:
- Builders’ foam or ordinary silicone in compartment walls
- Fire-rated sealant that has cracked or shrunk back
- Unsealed joints where partitions meet the slab
- Fire seals cut back for extra cables and never reinstated
For a hotel such as The George And Dragon Hotel (0.8 miles north of Bisham), penetration seals are worth checking after any refit or services upgrade.
What your quote should include
- Can the work be phased to keep areas open?
- How the joint faces will be prepared and primed
- The named product and why it was chosen
- Their approach to joint depth and backing
Questions we’re asked in Bisham
How does the move away from BS 476 affect penetration seals in Bisham?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Do you seal service penetrations in hotels around Bisham?
Yes, where the specification calls for fire-rated sealant. Each seal follows the tested detail, and rooms are done in turn.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
How do I request a quote?
The quote form is the simplest route, though you can also give us a call on 01277 525 020 or send details through our quote form. Include photographs or drawings if you have them.
How many days will you need on site?
It depends on the scope, but the work normally takes anything from one day to a planned run of visits, depending on the number of seals and the access. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
When can you be on site?
We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.
Maintenance after handover
A few simple habits keep the new joints working:
- Don’t let anyone top up a fire seal with the wrong product
- Record which product was used where
- Have penetrations checked while they can still be seen
- Ask which product is in place before decorating
After every round of M&E works, check that the openings created have been sealed. Building it into each contractor’s sign-off keeps the walls intact.
Keep a register of where seals are and what they are made of. It tells the next contractor exactly what to reinstate.
Why deal with it now?
An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. Putting it right is usually a modest job when the openings are accessible. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Around Bisham, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we will quote for the lot.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

How the job changes by surface
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on and we confirm each before sealing.
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Small sizes are sometimes covered by an intumescent sealant detail, but many need a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.
For managing agents and facilities managers
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
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.
