Fire rated sealant in Whistley Green, done properly
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. Each gap is sealed to the product maker’s tested detail for its size and substrate. We are often asked to deal with fire stopping disturbed by later work and unsealed gaps around fire door frames, across flats & HMOs, linear gaps and service penetrations.
Work in a small place like Whistley Green is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.
All our work comes with a one-year guarantee.

I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Can you tell me how many minutes the seal will last?
We do not issue ratings or certificates ourselves. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves, and we install to them.
What fire rated sealant looks like in Whistley Green
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 are given, installing the product to its tested details.
For landlords with property near Twyford station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
Whistley Green is about 2 miles east of Woodley, in Wokingham. Jobs in Whistley Green get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. We cover 35 towns and villages across Wokingham.

What happens if it’s left?
Doing it once, properly, beats doing it twice. Work that does not follow the tested detail may have to come out again once someone inspects it. Older cottages and farmhouses around Whistley Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
When to call us in Whistley Green
Gaps also open up as buildings move: cracked or debonded sealant leaves an open route through the wall. Damage from cleaning, knocks and maintenance adds to it.
Keep an eye out for any of the following:
- Gaps filled with a product that isn’t fire-rated
- Old fire sealant that has split or come away
- Seals cut through by electricians, plumbers or data installers
- Gaps flagged on a fire risk assessment
Managing a site like St Nicholas Church of England Primary? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

What sealant work cannot fix
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Deciding what fire stopping a building needs
- Big openings where sealant alone is not the tested solution
- Sign-off of the building, which sits with building control or your assessor
If in doubt, ring 0345 464 0079 or email us and we will say what we think before you book.
What we seal
- Pipe & cable gaps
- Flats & HMOs
- Linear gaps
- Service penetrations
- Plasterboard & masonry
- Door frames

What happens on the day
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes from a few hours to a few days, depending on the number of gaps and the access. Somewhere as small as Whistley Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used for your records.
Preparing for the visit
- Mention any parking rules near the property
- Where the joints are inside, avoid wetting them before we arrive
- On commercial sites, let us know about site rules

Keeping the joints in good condition
Looking after new joints is easy:
- Photograph sealed gaps before they’re covered up
- Store the list of sealed gaps with your building paperwork
- Do not fill fire-stopping gaps with ordinary foam or silicone
- Flag any open gap you spot round a pipe or cable
Don’t drill through or remove a fire seal without putting it back properly. New services through a sealed wall should include fire stopping in the plan.
It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole.
