Fire rated sealant for homes and businesses in Lower Assendon
Door frame gaps, linear joints and holes around services all have their own details. Measuring the gap and checking what it’s made of comes first, then the sealant goes in to the depth the product’s details set. If you have damaged fire sealant left by other trades and linear gaps at the head of walls, we can help, whatever the surface.
If you have holiday lets, a converted barn used for business or a community building near Lower Assendon, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of gaps, and longer for a whole building, and the area is left clean. Somewhere as small as Lower Assendon, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Access to each area is agreed so the work can run in order.
- We take out any damaged or unsuitable sealant.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area
- Mention any leaks or damp you’ve noticed

Advice
Aftercare tips
A little care helps the new joints last. Our advice:
- Never patch a fire seal with standard sealant
- Include hidden areas like risers in routine checks
- Keep photos of seals that will be hidden
- Tell trades working in the building that fire seals must be put back
Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some cannot and we will tell you which one you have.
It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes.
Work for landlords, hotels and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll quote.
Failed sealant is one of the commonest items on a check-out report. Several properties can be quoted together.
Leave it or put it right?
Squirting in whichever sealant is nearest does not make a fire seal. A fire-rated product only performs as tested when it’s installed to its tested detail, 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 Lower Assendon, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

What fire rated sealant looks like in Lower Assendon
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. There are hotels and other places to stay in and around Lower Assendon. Hotel work can be planned room by room, with out-of-hours working where needed.
Schools such as Rupert House School are buildings too, and fire-stopping around service openings should be restored whenever new services go in. For buildings such as Church of St Anne, older buildings that have had new heating or wiring often have service gaps worth checking. Rented homes near Henley-On-Thames station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Surface by surface
Service penetrations
New gaps tend to show up where services have been added. Old or unsuitable filler comes out before the right sealant goes in over any backing the detail calls for.
Plasterboard walls
Holes in plasterboard are often cut roughly for services. Gaps that are too big for sealant alone need a different detail, and we will tell you.
Your questions about fire rated sealant in Lower Assendon
Do you cover smaller places like Lower Assendon?
Yes. Lower Assendon is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you take on hotel work around Lower Assendon?
Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Where is Mr Mastic based?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
How long does the job take?
Most jobs take a few hours for a handful of gaps, and longer for a whole building. Your quote will say how long we expect yours to take.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
