What affects the cost of fire rated sealant
You will get a clear quote before work begins. It’s based on:
- How many areas need sealing
- The size of the job
- The type of sealant required
- How easy the joints are to reach
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What to tell us for a quote
To make quoting easier, please include:
- Whether it has been sealed before
- What the problem is, such as mould, gaps, leaks or cracking
- Pictures of the joints, sent by email
- The type of property
Every job is quoted individually, so the first step is telling us about yours. Simply phone 0345 464 0079 or drop us an email and describe the job and send pictures if you have them.
Fire rated sealant in Ascot, done properly
Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. If you have seals cut through by electricians, plumbers or data installers and gaps left after a refit or conversion, we can help, whatever the surface.
In a village or hamlet like Ascot, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.
We stand behind the work with a one-year guarantee.

Workplaces and buildings in Ascot
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 are given, installing the product to its tested details.
If you let a flat or house near Ascot station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Schools such as South Ascot Village Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

Ascot: your questions answered
Is Ascot within the area you cover?
Yes, Ascot is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Ascot station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Is intumescent sealant the same as fire-rated sealant?
An intumescent sealant expands when it gets hot to help seal the gap. It’s one type of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Can you seal over the old sealant?
No, it won’t last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
What do you need from me for a quote?
Let us know what needs doing and where, with pictures by email if possible. We will ask anything else we need to know.
Are you insured?
Yes. Mr Mastic is fully insured.

Why it’s worth doing now in Ascot
An open gap in a fire-resisting wall is a route for smoke and fire. A proper seal lets the wall do its job again, and the sealing itself is often a contained piece of work. In a small place like Ascot, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or email us for an honest opinion and a quote.
Why us?
- Old sealant always removed completely
- Full insurance on every job
- Experience in homes, commercial sites and hotels
- 12-month guarantee on every job

What happens on the day
We keep the work tidy and contained to the joints we’re treating. The job generally takes from a few hours to a few days, depending on the number of gaps and the access, and we tell you how long to leave it before we go. In a small place like Ascot, access is normally the main thing to plan. 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.
Before we arrive
- Clear the area around the work
- Tell us about any water getting in
- Mention if the joints have been sealed before

Signs you need fire rated sealant in Ascot
Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Out of view, damage sits unnoticed until someone inspects.
Look out for any of the following:
- Open joints along the top of partitions
- Old fire sealant that has split or come away
- Door frames with gaps between frame and wall
- Holes left by a change of layout
If you look after a church, hall or community building such as Church of All Souls, service openings in its walls need the right fire-rated sealant, as in any building.
What to look for in a quote
- What happens if they find a problem under the old sealant
- What preparation is included
- Which colour the sealant will be
- Are they insured?
Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Take photos of fire stopping before ceilings or boxing go back
- Plan fire stopping into any work that goes through walls or floors
- Check whether a sealant can be painted before decorating over it
- Look in service cupboards and ceiling voids from time to time
Let contractors know where fire stopping has been done, and make sure anything they disturb is resealed with a suitable product. A lot of damaged fire stopping comes from later work.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.
