Need fire stopping in Upton?
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
From enquiry to sign-off
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before the next one starts. Work in places the size of Upton is planned as a single visit where we can. Clear photographs and measurements help us bring the right products.
- 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.
- Foam, ordinary sealant and debris come out so the seal starts clean.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Tell us which areas need to stay in use
- Send any specification or drawings in advance

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Fire stopping in Upton, done properly
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4 and the results are classified to BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. If you’re dealing with seals disturbed by maintenance and left open and expanding foam used as fire stopping, we can put it right, whatever the surface. Most enquiries from Upton start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Fire-rated sealing in a place like Upton is normally a single building at a time. Send the specification, drawings or photographs of the openings and we’ll quote to suit.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Common questions from Upton clients
Do you take on work at healthcare sites like Upton Hospital?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
Does your area include sites such as Slough Interchange Industrial Estate, near Upton?
Yes, sites like Slough Interchange Industrial Estate are within our area, along with the rest of Upton. Send details of the unit and the work through our quote form for a quick quote.
Do you cover Upton?
Yes. We take on work across Upton, with one number for every area we cover.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Can you send site paperwork?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
How long does a typical visit take?
That varies with the scale of the job, but the work usually 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 will give you a timescale with the quote.
Do you design or specify fire stopping?
No. Deciding what is needed sits with the designer, fire engineer and building control. Our role is fitting the specified fire-rated sealant, following the maker’s tested details.
When it isn’t the sealant
We check first that sealant really is the fix. It isn’t the answer for:
- Fire doors, dampers or other fire safety equipment
- Deciding what a wall or floor needs, which belongs to the designer
- Approving the work on behalf of building control
If you’re not sure, just phone 01277 525 020 or send photos by email and we’ll give you a straight answer.
Joints and surfaces we work on
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Cable penetrations
- Pipe penetrations
- Service gaps in risers
- Linear gaps at wall heads
Keeping the joints sound
Regular inspection catches problems early. In particular:
- Keep general-purpose fillers away from compartment walls
- Settle who seals which penetrations at the start of a project
- Include service cupboards in routine inspections
- Check with the data sheet before painting over fire sealant
Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.
A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate.
Fire-rated sealing for Upton buildings
Approved Document B is the English guidance that covers fire stopping around 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. We install whatever has been specified, to the product’s tested detail. A 2-mile radius around Upton takes in a good number of hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.
Workshops and IT rooms at colleges like Slough & Langley College (2 miles east of Upton) are re-serviced often, leaving penetrations to seal. In a hotel such as Skyways Hotel, which lies east of Upton, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. On estates like Slough Interchange Industrial Estate (0.6 miles north of Upton), the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

Surface by surface
Risers and ceiling voids
Voids hide a lot of unsealed openings. We follow your schedule area by area.
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. The gap is measured at the widest point so we know it sits within the tested range, and any outside it are raised with you.
Leave it or put it right?
An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. Sealing them to the specified detail deals with the fire risk first. In a smaller place such as Upton, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.
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 fixed quote.
