Fire rated sealant in Hedsor, done properly
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. Common call-outs are for gaps where walls meet ceilings or slabs and unsealed gaps where pipes and cables go through a wall, on service penetrations, door frames and pipe & cable gaps.
For holiday lets, converted business premises or a community building near Hedsor, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

What fire rated sealant looks like in Hedsor
There are hotels and other places to stay in and around Hedsor. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. 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.
Managing a site like St Paul's Church of England Combined School? Then gaps opened by contractors for new cabling are a common finding in schools and offices. Rented homes near Bourne End station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.
Hedsor is about 3 miles south-west of Beaconsfield, in Buckinghamshire. Homes, rented property, offices and hotels in Hedsor can book us for fire rated sealant, old or new, large or small.

What the job involves on each surface
Door frames
Frame gaps are generally hidden behind the architrave. We seal any open gap to the product’s tested details.
Flats and HMOs
Conversions generally leave a mix of old and new service holes. The gaps on your list are sealed with a fire-rated product and record where they are.
What we can’t put right
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Walls or floors that weren’t built to resist fire
- Openings too large for sealant, which need batts, boards or another system
- Fire doors that need new seals, closers or hardware
If in doubt, call 0345 464 0079 or send us an email and we will say what we think before you book.
What we seal
- Plasterboard & masonry
- Pipe & cable gaps
- Linear gaps
- Door frames
- Flats & HMOs
- Service penetrations
What we’re called out for in Hedsor
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 particularly when it was the last job before handover.
Most people get in touch after spotting one of these:
- Door frames with gaps between frame and wall
- Sealant items on a fire risk assessment action list
- Unsealed gaps where pipes and cables go through a wall
- Standard silicone or caulk in a fire-stopping gap
Community buildings like Cores End United Reformed Church are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

- How the surfaces are prepared before sealing

Hedsor: your questions answered
Do you work for hotels and guest houses in Hedsor?
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.
Will you come out to Hedsor?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few photos.
What fire rating will the seal have?
We do not give ratings or certificates for our work. Your specification sets the requirement, and we apply a product tested for it, recording the locations and products.
Do you do fire sealant around door frames?
Yes, if the gap is within the product’s tested range. We seal the frame-to-wall gap, not the door itself, and we will mention anything we notice about the door.
Do you have insurance?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
Where is Mr Mastic based?
We’re based in Crawley, and we work across South East England, London and Scotland.
How long does the job take?
Typically it takes anything from a few hours to several days, depending on how many gaps there are. Bigger jobs take longer, and we’ll say how long yours will take.
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Get damaged fire seals looked at promptly
- Tell trades working in the building that fire seals must be put back
- Keep the record of products and locations with your fire safety documents
- Keep pictures of seals that will be hidden
Avoid covering a sealed gap with anything that is not part of the tested detail. If it needs repair, use the same type of product. We can tell you which product we used.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.
The process
At the end, we look at the finished work together and tell you how long to leave it. The visit itself generally takes from a few hours to a few days, depending on the number of gaps and the access, depending on how much there is to do. Somewhere as small as Hedsor, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- We measure every gap and note what it’s in and what passes through.
- Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your records.
Before we arrive
- Let us know about earlier repairs to the joints
- Keep pets and children clear of the area while we work
- Mention any parking rules near the property

Why deal with it now?
An open gap in a fire-resisting wall is a route for smoke and fire. Sealing it properly restores what the wall was there to do, and the work involved is often modest. In a small place like Hedsor, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
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.
