Fire rated sealant in Oxhey, done properly
Bigger jobs can be worked through in stages, flat by flat or floor by floor, noting the locations and products as we go. That record is useful for your files and for whoever looks at the building next. We are often asked to deal with old fire sealant that has split or come away and unsealed gaps where pipes and cables go through a wall, on pipe & cable gaps, linear gaps and service penetrations.
Around a place like Oxhey, halls, schools and small businesses all have washrooms and kitchens used by many people. Their sealant and fire-rated joints are as important as those in any bigger building.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Your questions about fire rated sealant in Oxhey
I let a flat near Bushey station. Can you help?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
Do you take on hotel work around Oxhey?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
Where is Mr Mastic based?
Our base is Crawley. We work across South East England, London and Scotland.
Do you have insurance?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Do you do fire sealant around door frames?
Yes. The joint between frame and wall is sealed with a fire-rated sealant. The door leaf and its hardware need a door specialist.
Will we have a record of what was sealed?
Yes. We record the locations we have sealed and the products used.
How long will you be here?
Typically it takes a few hours for a handful of gaps, and longer for a whole building. Larger jobs naturally take longer, and we will say how long yours will take.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Tell trades working in the building that fire seals must be put back
- Include hidden areas like risers in routine checks
- Allow for resealing whenever new services are run
- Get damaged fire seals looked at promptly
Do not add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. Ask us if you’re not sure which product was used.
Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole and the list grows.
How the visit works
We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. It normally takes from a few hours to a few days, depending on the number of gaps and the access. In a smaller place like Oxhey, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- 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 files.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Clear the area around the work
- Mention any tricky access

Do you need fire rated sealant in Oxhey?
Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. We see plenty of fire stopping that was hurried.
It’s worth asking for a quote if you see:
- Gaps flagged on a fire risk assessment
- Gaps around pipes and cables through fire-resisting walls
- Gaps where walls meet ceilings or slabs
- Gaps left after a refit or conversion
For landlords with property near Bushey station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
Questions to ask before booking
- Is the old sealant removed completely?
- How much experience the applicator has
- What happens if they find a problem under the old sealant
- How the surfaces are prepared before sealing
What fire rated sealant looks like in Oxhey
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 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 Oxhey. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.
Schools such as Bushey Manor Junior School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. Community buildings like Church of St James are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

- Construction that does not provide fire resistance on its own
- Large holes that need a different fire-stopping system

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 gives you evidence that the item was dealt with. Around Oxhey, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

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.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
