About our fire stopping in Wembley
A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, and they are easy to forget. We close the openings listed on your schedule, using the specified sealant and detail. We work on linear gaps at wall heads, small duct penetrations where the tested detail allows and cable penetrations, and what we are called in for most is seals disturbed by maintenance and left open and unsealed openings around new pipes and cables. Facilities teams, main contractors and managing agents in Wembley tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
London has many occupied offices, blocks and mixed-use buildings where services are added and rerouted all the time. Where the specification names fire-rated sealant, it goes in exactly as the manufacturer’s test evidence shows for that wall or floor.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Compartment walls and floors in Wembley
Two care or nursing homes sit less than 2 miles from Wembley. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. We install fire-rated sealant to the tested detail where it is specified. Every new tenant in a London building tends to bring new cabling, and with it new holes through compartment walls. Where fire-rated sealant is specified, we install it to the tested detail under the building’s permit-to-work arrangements.
For an estates team at a campus like Westminster University (1.7 miles north-west of Wembley), summer M&E works are normally followed by a round of penetration sealing. Theatres, wards and plant rooms at sites like Northwick Park Hospital (to the north-west of Wembley) all have compartment walls crossed by services.

Common problems we fix in Wembley
Most open service penetrations are left by later work. New cabling, rerouted pipework or a data route drilled through a riser leaves an opening that nobody returns to. Over a few years of fit-outs, a wall can collect a lot of these.
Look out for the following:
- Head-of-wall gaps with no fire seal
- Hidden openings found during inspections
- Penetration schedules that need working through
- Damaged fire seals in risers and voids
Colleges such as Regent College (0.7 miles south of Wembley) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.
What to look for in a quote
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Proof of insurance
- How the existing material will be dealt with
- Are they CHAS accredited or on Constructionline?
How the job changes by surface
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. Each gap is measured where it is widest so we know it sits within the tested range, and any that don’t are flagged.
Risers and ceiling voids
Risers and ceiling voids hold most of a building’s service penetrations. Access is often tight, so we agree it with you in advance.
Questions we’re asked in Wembley
Can you seal penetrations in a hotel in Wembley after a refit?
Yes, where the specification calls for fire-rated sealant. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.
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. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
Can you quote from photographs?
It depends on the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs usually get a visit.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
What do you charge?
We don’t publish prices, as every site differs. Send photographs or drawings and we will price it at a fixed figure.
Can the building stay open while you work?
Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.
On site: what to expect
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes anything from one day to a planned run of visits, depending on the number of seals and the access, and our waste is bagged and taken away as we go. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- The specification and schedule come first, so we know which details apply.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out so the seal starts clean.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
Preparing the site
- Tell us what induction or permit system the site runs
- Tell staff and tenants when we’ll be in
- Agree which areas must stay open

Building owners, agents and FMs in Wembley
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Site staff or a sealant specialist?
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.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Leave it or put it right?
An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail, so it makes sense to get it right first time. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.
