Fire rated sealant for homes and businesses in Woodside
We don’t assess buildings or decide what fire stopping is needed; your assessor, designer or building control sets that out. What we do is apply the right product to that specification, properly and neatly. If you have sealant items on a fire risk assessment action list and damaged fire sealant left by other trades, we can put it right.
Work in a small place like Woodside is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.
Each job carries a 12-month guarantee, whatever its size.

Why deal with it now?
Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up means you can show the action was taken. Where a wall is exposed, as many are in small places like Woodside, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
Why choose Mr Mastic in Woodside

What should I tell you?

Can you give us a record of the work?
Yes. We note each location and the product that went in, so you have it on file.
Are you insured?
Yes. We’re fully insured for domestic and commercial work.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all.
Can you fill the gap behind a fire door frame?
Yes. Gaps behind architraves are a common job for us. Doors, seals and closers need a door specialist.
What the job involves on each surface
Door frames
The gap between a door frame and the wall around it needs sealing as well as the door itself. We fill it with a fire-rated product suited to the materials either side.
Linear gaps
Long, narrow gaps appear where walls meet slabs and ceilings. They’re sealed with a fire-rated sealant over backing where the detail calls for it.
Workplaces and buildings in Woodside
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.
Managing a site like Cranbourne Primary School? Then service openings in fire-resisting walls need checking after any refurbishment. Letting a property close to Ascot station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

When to call us in Woodside
Many open fire-stopping gaps are made after the building is finished. Electricians, plumbers and data installers drill through walls and ceilings and the hole round the new service is not always sealed again.
Signs it’s time to call us include:
- Joints picked up in a fire-stopping survey
- Seals cut through by electricians, plumbers or data installers
- Cracked or shrunken fire-rated sealant
- Open gaps behind door architraves
If you look after a church, hall or community building such as Church of St Peter, older buildings that have had new heating or wiring often have service gaps worth checking.
Questions to ask before booking
- Is VAT in the price?
- What preparation is included
- Whether you can choose the colour
- Who does the work, and how experienced they are
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Tell trades working in the building that fire seals must be put back
- Get damaged fire seals looked at promptly
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- Allow for resealing whenever new services are run
Do not drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.
Open gaps don’t only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
Landlords, agents and businesses in Woodside
Housing providers, facilities teams and property managers book us too in Woodside and across Windsor and Maidenhead. We can quote a run of properties together.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
What we can’t put right
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Deciding what fire stopping a building needs
- Big openings where sealant alone is not the tested solution
- Fire doors that need new seals, closers or hardware
If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.
