Fire stopping in Ash, 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 have old intumescent sealant that has split away and unsealed joints where partitions meet the slab, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Ash tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Fire-rated sealing in a place like Ash is usually a single building at a time. With the specification and photographs of the gaps, we can give a fixed quote and bring the right products.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Compartment walls and floors in Ash
Ash lies roughly 61 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.
For a building such as Church of St Nicholas, new heating or data runs are the usual reason penetrations need sealing. Schools such as Ash Cartwright and Kelsey Church of England Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. For a building at a site such as Birnham Farm Business Centre, 1.4 miles south-east of Ash, a check of penetration seals after each fit-out is good practice.
Ash is about 7 miles north-west of Deal, in Kent. If you are looking for fire stopping in Ash, we can help, as we do across Kent. Ash is one of 931 places in Kent on our list. Our London page has more on work in that area (61 miles or so).

Site staff or a sealant specialist?
Putting right a botched joint often costs more than sealing it well at the start, 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.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Maintenance after handover
To get the most from the new sealant:
- Have penetrations checked while they can still be seen
- Look above ceilings when tiles are lifted for other jobs
- Treat an open penetration as a priority repair
- Ask which product is in place before decorating
Once the seals are in, tell other trades they exist and must not be disturbed. Any seal cut back for a new service needs reinstating to its tested detail.
On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned.
What we can’t put right
Being straight saves everyone time. New sealant won’t cure:
- Construction that lacks the fire resistance the seal relies on
- Approving the work on behalf of building control
- Reviewing a building’s overall fire safety
If in doubt, speak to us on 01277 525 020 or email us and we’ll say what we think before you book.

Questions we are asked in Ash
Is Ash too small for you to travel to?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work at a site such as Birnham Farm Business Centre, by Ash?
Yes. Estates, retail parks and business parks around Ash, Birnham Farm Business Centre among them, are all within reach. A few photos and the unit address let us price the work.
What do BS EN 1366-3 and BS EN 13501-2 mean?
BS EN 1366-3 covers penetration seals and BS EN 1366-4 covers linear joints. Results are classified under BS EN 13501-2. The rating applies to the product as tested.
Do you design or specify fire stopping?
No, that isn’t our role. With the designer’s details in hand, we can price the sealant elements.
Can you reseal penetrations after our M&E works?
Yes. Send the schedule or marked-up drawings and the specified product details for a fixed quote. We can follow the services contractor floor by floor keeping pace with the programme.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
How long does a job like this take?
That varies with the scale of the job, but the work typically takes anything from one day to a planned run of visits, depending on the number of seals and the access. For bigger or phased jobs, we will set out a timescale with the quote.
Why deal with it now?
A seal that doesn’t match its tested detail gives false comfort. The fix is to remove it and reinstall to the detail, so it makes sense to get it right first time. For buildings in places like Ash, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Our process
Before we leave any area, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. Several jobs near Ash can be grouped on one trip. Tell us your site hours and we’ll plan around them.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- We fit the backing the detail asks for, to the stated depth.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
Getting the site ready
- Send your site hours and access windows
- Tell us which areas need to stay in use
- Let building users know which areas are affected
