Fire stopping near Crayford
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Surface by surface
Metal pipes
Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on.
Plastic pipes
Waste and drainage pipes through floors are a frequent case. The detail decides whether sealant alone is enough, and we won’t substitute it for a specified collar.
Fire stopping for commercial buildings in Crayford
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. We work on joints between fire-resisting walls and floors, cable penetrations and pipe penetrations, and the usual reasons a site gets in touch are fire seals cut back for extra cables and never reinstated and non-fire-rated filler around services. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Crayford, preparation and product choice get the time they need.
Taller residential buildings in London may fall under the Building Safety Act’s higher-risk regime, where fire-stopping records get close attention. Our part is installing the specified fire-rated sealant; tell us what records you need and we will confirm with the quote.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When something else is needed
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:
- Deciding what a wall or floor needs, which belongs to the designer
- Issuing fire ratings or certificates for seals
- Openings that need collars, wraps, batts or boards rather than sealant
If in doubt, give us a call on 01277 525 020 or use the quote form and we will say what we think.
Surfaces we seal
- Service gaps in risers
- Cable penetrations
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Linear gaps at wall heads
Do you need fire stopping in Crayford?
Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. It may look closed, but it has no tested fire performance in that position.
If one of these sounds familiar, it’s time for a closer look:
- Old intumescent sealant that has split away
- Fire seals cut back for extra cables and never reinstated
- Expanding foam used as fire stopping
- Unsealed joints where partitions meet the slab
At a retail site such as Tower Retail Park, which lies north of Crayford, walls between units may be fire-resisting, so services added in a refit need the specified seal.
What to look for in a quote
- How long is the guarantee, and what does it include?
- How the joint faces will be prepared and primed
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Is the sealant right for the movement and the substrate?

Questions about Crayford
Will you plan work around the academic year at somewhere like University of Greenwich?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Do you seal service penetrations in hotels around Crayford?
Yes. We install fire-rated and intumescent sealant where it is specified. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators.
Do you cover Crayford?
Yes. We cover Crayford, and the simplest way to start is to speak to us on 01277 525 020 or email drawings and photos.
Can the sealant be colour-matched?
It depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Who decides which product is used?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.
Quoting for work in Crayford
A fixed quote reflects the actual work. It allows for:
- Which sealant the job calls for
- How much there is to seal
- Removal of failed or old sealant
- Travel to remote or island sites
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Before you send an enquiry
There’s no need for a formal survey. A few details are enough to get going:
- Clear photos of the problem areas
- Approximate linear metres or a joint schedule
- Access details, including height
- Any specification or named product
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, ring 01277 525 020 or send details through our quote form.
Our process
Occupied buildings need a little choreography. 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. All of Greater London is in the ULEZ, and kerbside space in Crayford can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We read the specification, drawings or penetration schedule you send.
- 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.
- We fit the backing the detail asks for, to the stated depth.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Preparing the site
- Send your site hours and access windows
- Confirm the product named in the specification
- Explain the parking and delivery arrangements

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Fire-rated sealing for Crayford buildings
For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail. Every new tenant in a London building tends to bring new cabling, and with it new holes through compartment walls. Penetrations are sealed with the specified product, to its tested detail, under the building’s own permit rules.
For an estates team at a campus like University of Greenwich, 3.8 miles east of Crayford, summer M&E works are usually followed by a round of penetration sealing. At a college such as North Kent College, which lies south-east of Crayford, checking penetration seals after summer M&E works is good practice.

Keeping the joints sound
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Get seals inspected before ceilings and boxing close
- Brief every trade that openings they make must be sealed
- Settle who seals which penetrations at the start of a project
- Record which product was used where
Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t, so check the product data first.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. That way the opening is sealed while the trade and access are still there instead of being left for someone else.
