Fire stopping for commercial buildings in Ditton
No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. Before we seal anything, we check the opening against the detail it is meant to follow. We work on small duct penetrations where the tested detail allows, pipe penetrations and cable penetrations, and what we’re called in for most is fire-stopping items raised at inspection or handover and service penetrations left open after M&E works. Facilities teams, main contractors and managing agents in Ditton tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Barn and farm-building conversions near places like Ditton often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Surface by surface
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. The gap is measured at the widest point against the detail’s limits, and any outside it are raised with you.
Drylining partitions
Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do, and the detail may call for board patching or another product.
Fire stopping in Ditton: the local picture
A 2-mile radius around Ditton takes in plenty of hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. Ditton lies roughly 20 miles out from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls.
For a unit at a centre such as Slough Retail Park, 2.8 miles north-west of Ditton, penetration seals are worth checking after each shop fit. For a site team at a college like Slough & Langley College, 1.3 miles north-east of Ditton, fire-rated sealing is best scheduled after the summer works.

Our process
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. For a building around Ditton, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- Where the detail needs backing, it goes in at the stated depth.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
What we need from you
- Arrange parking or a loading space
- Have the specification and drawings to hand
- Let building users know which areas are affected

Leave it or put it right?
Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach. Converted and older buildings near places like Ditton tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
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.

When to bring in a specialist
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
What we are called out for in Ditton
Some service penetrations were never sealed at all because they sat out of sight above a ceiling or inside a riser. Inspections, refurbishments and ceiling access normally bring them to light.
Look out for the following:
- Head-of-wall gaps with no fire seal
- Builders’ foam or ordinary silicone in compartment walls
- Fire-stopping items raised at inspection or handover
- Service penetrations left open after M&E works
For a building at a site such as Portland Business Park, which lies south-west of Ditton, a check of penetration seals after each fit-out is good practice.
Questions to ask before you book
- Do they follow the manufacturer’s priming guidance?
- Their plan for phasing and protecting the area
- Who will actually carry out the work
- Proof of insurance
Looking after the joints
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- File the specified details where the next contractor can find them
- Check with the data sheet before painting over fire sealant
- Brief every trade that openings they make must be sealed
- Have penetrations checked while they can still be seen
Once the seals are in, tell other trades they exist and must not be disturbed. Any seal cut back for a new service needs reinstating to its tested detail, by someone who knows the system.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. That way the opening is sealed while the trade and access are still there.
Your questions answered
What does the BS 476 change mean for fire-rated sealant in Ditton?
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.
Can work at a site such as Royal Holloway University fit around teaching?
Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can the building stay open while you work?
Typically, yes. We phase the work so most of the building stays in use.
Can you fit around our working hours?
Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
How long do sealant joints last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
