Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
What we can’t put right
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Deciding what a wall or floor needs, which belongs to the designer
- Construction that lacks the fire resistance the seal relies on
- Large openings beyond what any sealant detail covers
If in doubt, give us a call on 01277 525 020 or email a schedule or drawings and we will say what we think.
Surfaces we seal
- Cable penetrations
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Pipe penetrations
Fire stopping for commercial buildings in Pett Bottom
No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and raise it with you if it falls outside. If you are dealing with builders’ foam or ordinary silicone in compartment walls and penetration schedules that need working through, we can put it right. Whoever orders the work in Pett Bottom, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
Smaller places such as Pett Bottom still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Work we carry out in Kent comes with a 12-month guarantee. Should something we installed fail, call the office on 01277 525 020 or send photos by email and we will come back to it.

How a job runs
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence, and we clear our waste as we work. Jobs in and around smaller places like Pett Bottom are typically planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- 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.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- 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.
Preparing the site
- Share your working hours and any access restrictions
- Let building users know which areas are affected
- For older buildings, check the asbestos register before work

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Common questions from Pett Bottom clients
Does your area include sites such as Canterbury Business Park, near Pett Bottom?
Yes. We cover Pett Bottom and the area around it, including industrial estates, business parks and retail parks such as Canterbury Business Park. Photos and a short description are enough for a first look.
Is a hospital such as The Chaucer Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
What site paperwork can you supply?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. 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.
What does an EI 60 rating mean?
BS EN 1366-3 covers penetration seals and BS EN 1366-4 covers linear joints. Results are classified under BS EN 13501-2. That rating only holds when the product is installed to its tested detail.
Do you seal openings left by new services?
Yes. Share the penetration schedule and product details for a fixed quote. We can follow the services contractor floor by floor so areas aren’t left open.
Aftercare for building managers
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Get seals inspected before ceilings and boxing close
- Include service cupboards in routine inspections
- Put resealing into every M&E and fit-out package
- Check with the data sheet before painting over fire sealant
Once the seals are in, tell other trades they exist and must not be disturbed. If a seal has to be opened for a new service, it should be reinstated to the same detail using the same product.
On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts, and installation follows the programme.
What we are called out for in Pett Bottom
Most open service penetrations are left by later work. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser leaves an opening that nobody returns to. Over a few years of fit-outs, a wall can collect a lot of these.
Look out for the following:
- Seals that don’t match their tested detail
- Seals disturbed by maintenance and left open
- Builders’ foam or ordinary silicone in compartment walls
- Openings left by services added after handover
Holiday works at schools like Simon Langton Grammar School for Boys often leave service openings to seal before pupils return.
What your quote should include
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Is the sealant right for the movement and the substrate?
- Will CSCS-carded applicators be on site?
- Their plan for phasing and protecting the area

Why deal with it now?
Sealing behind the M&E trades area by area beats a sweep at the end. Openings are visible, access is open and nothing has to be taken down and each detail can be checked as we go. Converted and older buildings near places like Pett Bottom tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
