Fire-rated sealant in Chaddleworth, West Berkshire
Our applicators work in Chaddleworth on intumescent and fire-rated sealant around gaps, frames and service penetrations. Old sealant removed completely, joints prepared properly.
- Gaps filled with a product that isn’t fire-rated
- Damaged fire sealant left by other trades
- Open gaps behind door architraves
When to call us in Chaddleworth
Movement in the structure can open gaps too: cracked or debonded sealant leaves an open route through the wall. Knocks, maintenance and building work damage it further.
Signs it’s time to call us include:
- Holes left by a change of layout
- Open joints along the top of partitions
- Seals cut through by electricians, plumbers or data installers
- Gaps flagged on a fire risk assessment
For site and facilities teams at buildings such as Chaddleworth St Andrew's C.E. Primary School, fire-stopping around service openings should be restored whenever new services go in.

Fire rated sealant in Chaddleworth
Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. We cut out the wrong material and the gap is resealed with a product tested for that use. We work on linear gaps, service penetrations and door frames, and common reasons people get in touch are open joints along the top of partitions and fire seals that have cracked with movement.
Somewhere as small as Chaddleworth, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

Honest limits
New sealant cannot fix everything, and we’ll tell you before any work starts. It will not solve:
- Fire risk assessments, which need a qualified assessor
- Certifying a building or signing off its fire safety
- Openings too large for sealant, which need batts, boards or another system

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Can I do it myself?
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

The process
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes from a few hours to a few days, depending on the number of gaps and the access. In a small place like Chaddleworth, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- We put in whatever backing or fill the product detail specifies.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Finally, we list where we worked and what we used, for your records.
How to prepare
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any sign-in or site rules at work premises

Fire rated sealant around Chaddleworth
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
For buildings such as Church of St Andrew, older buildings that have had new heating or wiring often have service gaps worth checking.

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Get damaged fire seals looked at promptly
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Don’t paint over fire sealant until it has cured
- Make resealing part of every contractor’s brief
Avoid covering a sealed gap with anything that isn’t part of the tested detail. Repairs should use a matching fire-rated product. We can tell you which product we used.
An open gap is not only a fire issue: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.
Surface by surface
Linear gaps
Head-of-wall gaps are often hidden above suspended ceilings. We work along the whole run leaving no stretch unsealed.
Masonry and concrete
Preparation counts on brick, block and concrete. We brush and vacuum the gap and use backing where the detail needs it before the sealant goes in.
