About our fire stopping in Queensbury
On a fit-out or refurbishment, we follow the services contractors floor by floor. We work from your penetration schedule or marked-up drawings. Tell us what records you need and we’ll confirm with the quote. Most enquiries involve service penetrations left open after M&E works and unsealed penetrations discovered above suspended ceilings, on pipe penetrations, joints between fire-resisting walls and floors and cable penetrations. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Queensbury is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In London, higher-risk residential buildings under the Building Safety Act bring extra scrutiny of fire-stopping records. We install what the designer or fire engineer has specified, and if you need records of the work, tell us and we’ll confirm with the quote.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

After the work
Keep the joints in good shape with a few simple steps:
- Report damaged or disturbed seals as soon as they’re spotted
- Ask which product is in place before decorating
- Ask the designer to confirm details early on refits
- File the specified details where the next contractor can find them
Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original unless the designer specifies otherwise.
Write fire stopping into the scope of any work crossing a compartment wall or floor. Then the seal goes in while the area is open instead of being left for someone else.
Questions about Queensbury
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. We allow for the ULEZ, which covers every borough
Do you cover business parks and estates near Queensbury, such as Mill Yard Industrial Estate?
Yes. Estates, retail parks and business parks around Queensbury, Mill Yard Industrial Estate among them, are all within reach. To start, just phone 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Can you seal any opening with fire-rated sealant?
No. Each fire-rated sealant is tested for particular services, gap sizes and substrates. Outside that, a different product is needed, as set out by the designer.
Do you certify or sign off fire stopping?
No. We don’t certify or sign off fire stopping, and we hold no third-party fire-stopping installer certificate. Our part is fitting the specified product to its tested detail.
Do you work in Queensbury?
Yes. Queensbury is in our area, within our coverage of Greater London, South East England and Scotland. To discuss a job, ring 01277 525 020 or send details through our quote form.
Can you tell us what fire stopping our building needs?
No, we don’t design fire stopping. With the designer’s details in hand, we can price the sealant elements.
Can you quote from photos?
Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.
Fire-rated sealing for Queensbury buildings
London’s office and residential buildings are refitted constantly, and each round of cabling or pipework can leave open penetrations. Penetrations are sealed with the specified product, to its tested detail, under the building’s own permit rules. 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. What we install is set by the specification, and it goes in to the tested detail.
Large healthcare estates like Edgware Community Hospital, 1.3 miles to the north-east of Queensbury, change their services often, so penetration seals are worth checking after M&E work. At a university such as Westminster University, which lies south-west of Queensbury, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.
Queensbury is about 2 miles south of Stanmore, in Greater London. Commercial clients in Queensbury use us for work on service penetrations, as part of our coverage of Greater London. Queensbury is one of 764 places in Greater London on our list. For work in that direction, see our London page (11 miles or so).

When to bring in a specialist
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
On site: what to expect
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- 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.
- Mineral wool or other backing is fitted where required.
- 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.
Before we start on site
- For older buildings, check the asbestos register before work
- Confirm the product named in the specification
- Tell us which areas need to stay in use
Ask for a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.

What we are called out for in Queensbury
Some service penetrations were never sealed at all. They come to light during inspections, refits or when another trade lifts a tile.
If one of these sounds familiar, it’s time for a closer look:
- Fire stopping installed outside its tested range
- Unsealed penetrations discovered above suspended ceilings
- Openings left by services added after handover
- Fire-rated sealant that has cracked or shrunk back
Hotels like Kingslamd Hotel (0.6 miles south-east of Queensbury) are refurbished in phases, and each phase can open up compartment walls.

What the job involves on each surface
Drylining partitions
Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do.
Linear joints
Head-of-wall joints often have to absorb slab deflection. We use the product and backing the detail names for that movement.
