What affects the quote in Kingston Lisle
We quote each job individually. These are the things that affect it:
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
- The amount of work
- Whether the work is at height
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or email us and we will give you an honest view and a quote.
What to tell us for a quote
When you call or email, it’s useful to know:
- Photos by email, if that is easy
- The problem you’ve noticed
- Roughly how big the job is
- Any access issues, like height or stairs
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we will talk you through the work before giving you a price.

If you are dealing with sealant items on a fire risk assessment action list and linear gaps at the head of walls, we can help, on linear gaps, door frames and flats & HMOs alike.
If you have holiday lets, a converted barn used for business or a community building near Kingston Lisle, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

Different surfaces, different methods
Door frames
The gap between a door frame and the wall around it needs sealing as well as the door itself. We seal that gap with a fire-rated sealant suited to the frame and wall.
Plasterboard walls
Plasterboard partitions are common in flats, offices and conversions. The sealant has to be one tested in plasterboard for each gap size.
Workplaces and buildings in Kingston Lisle
In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details. There are hotels and other places to stay in and around Kingston Lisle. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.
Community buildings like Church of St John the Baptist are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. In and around Kingston Lisle, as anywhere, good fire rated sealant starts with a clean, dry, properly prepared joint.

FAQs for Kingston Lisle
Can you do fire rated sealant in Kingston Lisle?
Yes, Kingston Lisle is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.
Do you work for hotels and guest houses in Kingston Lisle?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
Can I choose the sealant colour?
Usually, yes. Sealants come in white, clear, grey and other colours for many products, and we will agree it with you first.
Do you provide details of the products used?
Yes. Locations and products are written up when we finish. Tell us if your assessor needs it in a particular format.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
How long does fire rated sealant take?
Most jobs take a few hours for a handful of gaps, and longer for a whole building. We’ll confirm how long when we quote.
Are you insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Can I use normal mastic around a pipe through a fire wall?
No. Standard sealants aren’t made or tested to stop fire. We cut it out and reseal with a fire-rated product.
DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Honest limits
It helps to know what we cannot do too:
- Fire risk assessments, which need a qualified assessor
- Sign-off of the building, which sits with building control or your assessor
- Construction that does not provide fire resistance on its own
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before booking.
What we seal

Why it’s worth doing now in Kingston Lisle
Squirting in whichever sealant is nearest doesn’t make a fire seal. Fire-rated products are tested in set gap sizes, depths and substrates, which is why we match the product and the method to each gap. Where a wall is exposed, as many are in small places like Kingston Lisle, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost reflects the work involved, not guesswork. That is why we ask about the job first.
