Owners, agents and contractors
Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Fire stopping for commercial buildings in Knowl Hill
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. We work on pipe penetrations, small duct penetrations where the tested detail allows and cable penetrations, and the failures we are asked to look at most are snag lists that include open service penetrations and head-of-wall gaps with no fire seal. A single leaking joint is often how a building in Knowl Hill first comes to us: we look at the rest while we’re there and tell you what we find.
Barn and farm-building conversions near places like Knowl Hill 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.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

FAQs: Knowl Hill
Can work at a site such as University of Reading fit around teaching?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Is Knowl Hill too far out for you?
Not at all. Knowl Hill is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
Do you certify or sign off fire stopping?
No. Approval sits with the designer, principal designer or building control. We will confirm the product and detail installed, and you can tell us what other records you need at quote stage.
What does an EI 60 rating mean?
Penetration seals are tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. Results are classified under BS EN 13501-2. The rating applies to the product as tested.
What will the job cost?
Each job is quoted on its own details. To get one, ring 01277 525 020 or send details through our quote form.
Do you have public liability insurance?
Yes. We are fully insured, including public liability cover.
Service penetrations in Knowl Hill buildings
Knowl Hill lies roughly 31 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls. Fire stopping of openings and penetrations in England falls under Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. We install whatever has been specified, to the product’s tested detail.
Large healthcare estates like St Mark's Hospital (3.3 miles east of Knowl Hill) change their services often, so penetration seals are worth checking after M&E work. Offices at parks like Castle End Business Park (to the south-west of Knowl Hill) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. At a college such as Berkshire College of Agriculture, 1.6 miles north-east of Knowl Hill, checking penetration seals after summer M&E works is good practice.

How the quote is worked out
Each job is priced on its own details. The main factors are:
- How much existing material needs removing
- Phasing around occupants
- How accessible the joints are
- Location, for remote and island sites
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.
What to include in your enquiry
For an accurate fixed quote, we need to understand the site. Useful things to include:
- Approximate linear metres or a joint schedule
- The type of building and who uses it
- Clear photos of the problem areas
- How the joints are reached, and at what height
Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to speak to us on 01277 525 020 or email a schedule or drawings.
Our process
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. For work around Knowl Hill, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- 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
- Clear stock, furniture or equipment away from the joints
- Tell us what induction or permit system the site runs
- Point out any areas we must not close
Ask for a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.
Advice
Why deal with it now?
The longer openings stay, the more there tend to be: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small, rather than turning into a full building survey and reseal. One visit to deal with every failing joint makes more sense than several trips to a place like Knowl Hill. Photos of every joint help us quote for the whole job.
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Surface by surface
Plastic pipes
Plastic waste pipes through slabs come up often. Whether sealant alone is acceptable depends entirely on the tested detail, and we’ll never swap a specified collar for sealant.
Cables and cable bundles
Data cabling added after handover is a regular cause of open service penetrations. We reseal around them to the specified detail, and we tell you if the bundle exceeds what sealant covers.
Looking after the joints
Keep the joints in good shape with a few simple steps:
- Include service cupboards in routine inspections
- Arrange inspection before areas are covered up
- File the specified details where the next contractor can find them
- Settle who seals which penetrations at the start of a project
Never top up a fire seal with foam, ordinary silicone or filler. A repair should use the original product, installed the same way.
Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts, and installation follows the programme.
