Fire stopping in Clare Market
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Fire stopping in Clare Market, done properly
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, often unnoticed. We close the openings listed on your schedule, using the specified sealant and detail. If you’re dealing with non-fire-rated filler around services and old intumescent sealant that has split away, we can help, on small duct penetrations where the tested detail allows, service gaps in risers and joints between fire-resisting walls and floors alike. One point of contact handles commercial sealant work in Clare Market from the first photographs to the final walk-round, for single jobs and planned programmes alike.
In London, higher-risk residential buildings under the Building Safety Act bring extra scrutiny of fire-stopping records. Our part is installing the specified fire-rated sealant; tell us what records you need and we’ll confirm with the quote.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Why it’s worth doing now in Clare Market
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. Openings are visible, access is open and nothing has to be taken down. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Sending details for a quote
There’s no need for a formal survey. A few details are enough to get going:
- Specification clauses that apply
- Anything awkward about access or site hours
- Whether the building will be occupied during the work
- Your programme or deadline
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, call the office on 01277 525 020 or email the details over.
For managing agents and facilities managers
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Your questions answered
Can you work around term dates at a campus such as King's College London?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Is hospital work, at somewhere like Royal London Hospital for Integrated Medicine, something you do?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
What happens if old sealant might contain asbestos?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Do you take on small jobs?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Do you hold third-party fire-stopping installer certification?
No, and we won’t imply otherwise. Some clients require third-party installer schemes even though the law doesn’t, so it’s worth checking what your contract says. Where it isn’t required, we install the specified sealant to the maker’s details.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
When something else is needed
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:
- Plastic pipes whose detail calls for a collar or wrap
- Issuing fire ratings or certificates for seals
- Deciding what a wall or floor needs, which belongs to the designer
If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.
What we seal
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Cable penetrations
- Small duct penetrations where the tested detail allows
- Pipe penetrations
- Linear gaps at wall heads
After the work
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Put resealing into every M&E and fit-out package
- Leave fire sealant to cure fully before covering it
- Arrange inspection before areas are covered up
- Foam or ordinary sealant is never a fire-seal repair
Keep the product data and installation details with the building’s fire safety information. Anyone resealing later needs to know which product and detail were used.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open instead of being left for someone else.
Our process
Working in a building that stays open takes some planning. We sign and contain the area we are in, with routes through the building left open and work section by section so the rest of the building stays in use. For a job in Clare Market, access comes first. Give us the hours we can be on site and we will schedule to suit.
- 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.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Getting the site ready
- Tell staff and tenants when we will be in
- Make sure the joints can be reached
- Send asbestos survey details if the building is pre-2000

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, give us a call on 01277 525 020 or email the details over.

Compartment walls and floors in Clare Market
With tenants changing and fit-outs following, London buildings see service routes altered again and again. We install fire-rated sealant where it is specified and work within the building manager’s permit system. A 2-mile radius around Clare Market takes in plenty of hotels. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product.
