Fire stopping for commercial buildings in Hamsey Green
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate, and we won’t pretend otherwise. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. Site teams most often ask us about damaged fire seals in risers and voids and improvised or mixed-product fire seals, on cable penetrations, pipe penetrations and linear gaps at wall heads. A specialist sealant contractor works differently from a general builder: on jobs in Hamsey Green, preparation and product choice get the time they need.
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.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Different surfaces, different methods
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed.
Drylining partitions
Service holes through plasterboard are frequently oversized or ragged. An oversized hole may be outside the sealant’s range and we will tell you what the detail says instead.
From enquiry to sign-off
Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. All of Greater London is in the ULEZ, and kerbside space in Hamsey Green can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
Before we start on site
- Send any specification or drawings in advance
- Tell us your opening times and when work is allowed
- Point out any areas we must not close
Request a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Leave it or put it right?
Open penetrations multiply: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable, rather than turning into a full building survey and reseal. Getting scaffold, permits or access booked in Hamsey Green takes effort, so it makes sense to deal with every failing joint while access is in place.
The price depends on the quantity of joints, what has to come out first and the access. Call for a fixed quote when you’re ready.

General trades versus a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Signs you need fire stopping in Hamsey Green
Damage plays a part too. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped, and the repair is often skipped.
Clients usually get in touch after noticing something like this:
- Non-fire-rated filler around services
- Fire stopping installed outside its tested range
- Service penetrations left open after M&E works
- Seals disturbed by maintenance and left open
For a unit at a site such as Church Walk Shopping Centre (2.7 miles south of Hamsey Green), any new service through a fire-resisting wall should be sealed to the tested detail.

Your questions answered
Could you schedule work at a campus like John Ruskin College for the vacation?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is a hospital such as Purley War Memorial Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Will you come and look before quoting?
It depends on the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also give us a call on 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.
Compartment walls and floors in Hamsey Green
Fire stopping of openings and penetrations in England falls under Approved Document B.

Either way, we install the specified product to its tested detail. Two care or nursing homes sit less than 2 miles from Hamsey Green. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal.
Colleges such as John Ruskin College, 2.4 miles to the north of Hamsey Green, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. Hotels like Selsdon Park Hotel (1.4 miles north of Hamsey Green) are refurbished in phases, and each phase can open up compartment walls.
