Fire stopping in Kingswood, done properly
No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. Before we seal anything, we check the opening against the detail it is meant to follow. The enquiries we see most involve damaged fire seals in risers and voids and builders’ foam or ordinary silicone in compartment walls, across pipe penetrations, linear gaps at wall heads and service gaps in risers. Most enquiries from Kingswood start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
For a smaller site near Kingswood, we plan to do all the penetrations in one go, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Questions about Kingswood
Is Kingswood too small for you to travel to?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Could you schedule work at a campus like Canterbury Christ Church University 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.
What do you charge?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.
Do you take on multi-site work?
Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
What changes on 2 September 2029?
For buildings in England, Approved Document B removes BS 476 references from 2 September 2029. Products are then judged on BS EN 13501-2 classifications, subject to transitional arrangements. Scotland follows its own Technical Handbook, including clause 2.1.14 on service penetrations.
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 work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
Cost factors for service penetrations
These are the things that shape the price:
- Travel to remote or island sites
- Which sealant the job calls for
- Access and working height
- How much existing material needs removing
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.
What to include in your enquiry
Good information means a firmer quote. When you get in touch, include:
- Any dates the work must fit around
- The asbestos register, for older buildings
- How the joints are reached, and at what height
- Whether the building will be occupied during the work
Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to ring 01277 525 020 or send details through our quote form.
Do you need fire stopping in Kingswood?
Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it, so it has to come out.
What tends to prompt an enquiry:
- Unsealed openings around new pipes and cables
- Damaged fire seals in risers and voids
- Fire stopping installed outside its tested range
- Fire-stopping items raised at inspection or handover
On a hospital site such as KIMS hospital, 5.2 miles north-west of Kingswood, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
Before you book anyone
- The named product and why it was chosen
- Who will actually carry out the work
- How the joint faces will be prepared and primed
- Will RAMS and insurance details be available?
General trades versus a specialist
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Building owners, agents and FMs in Kingswood
Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
Fire stopping around Kingswood: what changes locally
Kingswood is about 37 miles 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. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.
On a site such as Roebuck Business Park, 2 miles to the north-east of Kingswood, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product. In a school such as Kingswood Primary School, fire-rated sealant goes in around service penetrations where it is specified.

Our process
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For a building around Kingswood, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned so the seal starts clean.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Getting the site ready
- Have the specification and drawings to hand
- Let us know about inductions and permits
- Point out any areas we must not close

- Deciding what a wall or floor needs, which belongs to the designer
- Walls or floors that aren’t fire-resisting to begin with
