Fire stopping for commercial buildings in Crowthorne
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. Those on your schedule are closed with the specified product. The enquiries we see most involve fire seals cut back for extra cables and never reinstated and builders’ foam or ordinary silicone in compartment walls, across joints between fire-resisting walls and floors, linear gaps at wall heads and pipe penetrations. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Crowthorne is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Towns the size of Crowthorne have plenty of buildings with compartment walls: schools, care homes, surgeries, offices and blocks of flats. New cabling or pipework through a fire-resisting wall leaves a gap that has to be made good with the specified product.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

Your questions answered
What does the BS 476 change mean for fire-rated sealant in Crowthorne?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Do you cover business parks and estates near Crowthorne, such as Wellington Business Park?
Yes. Our area takes in Crowthorne and its surroundings, with estates and business parks such as Wellington Business Park included. A few photos and the unit address let us price the work.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Do you offer coloured sealant?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards, which many sites require.
Do you guarantee your work?
Yes. The 12-month guarantee covers our preparation and application, though not damage or work by other trades.
Will you quote for a small job?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
What we can’t put right
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Approving the work on behalf of building control
- Openings that need collars, wraps, batts or boards rather than sealant
- Designing or specifying fire stopping, which sits with the designer or fire engineer
If in doubt, call 01277 525 020 or send details through our quote form and we’ll say what we think.
Joints and surfaces we work on
- Pipe penetrations
- Cable penetrations
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Service gaps in risers
- Small duct penetrations where the tested detail allows
When to bring in a specialist
Some joints are best left to specialists: for instance 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.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Compartments and services around Crowthorne
In England, Approved Document B covers fire stopping of openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail. There are several hotels within about 2 miles of Crowthorne. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.
Hospital estates such as Broadmoor Hospital (to the east of Crowthorne) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. Schools such as Crowthorne Church of England Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. Tenant changes at parks like Wellington Business Park, 1 mile south-west of Crowthorne, bring new data and services, and openings through fire-resisting walls need the specified seal.

What else we do in Crowthorne
Different surfaces, different methods
Risers and ceiling voids
Openings above suspended ceilings are easy to miss. We work through the areas on your schedule methodically and tell you about openings outside the list.
Metal pipes
Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on, so we check each one.
On site: what to expect
We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Parking and loading for town-centre jobs in Crowthorne are worth mentioning when you send details. Industrial and business units typically have yard or car park space.
- We start with your penetration schedule, drawings or specification.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned first.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Before we start on site
- Send asbestos survey details if the building is pre-2000
- Tell staff and tenants when we’ll be in
- Point out parking and an unloading spot

Why it’s worth doing now in Crowthorne
Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme which is why earlier is better. In a town such as Crowthorne, a lot of buildings are older and have been altered over time, so joints between old and new are often the first to go. Renewing them before water gets in protects the fabric.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.
