About our fire rated sealant in Caversham
Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through, so we work to the manufacturer’s details. We work on door frames, linear gaps and plasterboard & masonry, and the jobs we see most are gaps left after a refit or conversion and seals cut through by electricians, plumbers or data installers.
If you look after a school, care home, pub or office in Caversham, washroom sealant, kitchen joints and fire-rated sealant around service openings all need upkeep. Out-of-hours working is possible to arrange.
Big or small, it’s backed by our 12-month guarantee.

Can you tell me how many minutes the seal will last?
Ratings and certification sit with the product’s test evidence and whoever specified the work. Our part is installing the specified product to its tested details and giving you a record of where it went.
What does intumescent mean?
An intumescent material expands when it’s heated. Intumescent sealants are a type of fire-rated sealant and which one is used depends on the job.
Can you seal over the old sealant?
No. We remove every bit of old sealant first, so the new sealant bonds properly.
What fire rated sealant looks like in Caversham
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We work to the specification you’re given, installing the product to its tested details. Caversham has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.
Rented homes near Reading station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a building such as The Hill Primary School, service openings in fire-resisting walls need checking after any refurbishment.

Aftercare tips
To keep the joints looking good and working properly:
- Include fire stopping when you schedule refits
- Tell trades working in the building that fire seals must be put back
- Do not fill fire-stopping gaps with ordinary foam or silicone
- Store the list of sealed gaps with your building paperwork
Avoid covering a sealed gap with anything that isn’t part of the tested detail. If it needs repair, use the same type of product. Ask us if you’re not sure which product was used.
A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded so the item can be closed.

How the job changes by surface
Door frames
Behind most architraves is a gap between frame and wall. Where it’s open, we seal it to the product’s details for that gap size so the architrave can be refitted.
Service penetrations
Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. We seal it with a product tested for that service and gap size.
Why it’s worth doing now in Caversham
Doing it once, properly, beats doing it twice. If the details weren’t followed, the seal may need redoing once someone inspects it. In Caversham, as anywhere, most leaks start as a small gap in a joint, and early is when they’re cheapest and quickest to sort.
Combining jobs into one visit is generally more efficient than separate visits. We’ll give you a clear price for the lot.

How the visit works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself normally takes a few hours for a handful of gaps, and longer for a whole building, depending on the size of the job. Parking in a town like Caversham is generally straightforward, but tell us if there’s a driveway or any restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed and the gap cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products for your records.
How to prepare
- Mention any parking rules near the property
- Try not to wet indoor joints just before the visit
- Mention any leaks or damp you’ve noticed
