Common questions in Coombe Hill
Do you work for landlords with property near Norbiton station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Do you cover Coombe Hill for fire rated sealant?
Yes. Our work covers London and the South East, and Coombe Hill is part of that. You can call 0345 464 0079 or send us an email and let us know what needs doing.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Can new sealant go over the old?
No, it will not last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
What do you need from me for a quote?
A short description and the location, with pictures by email if possible. If we need more, we’ll ask.
Will we have a record of what was sealed?
Yes. Every gap we seal is listed with the product used.

Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through, so we work to the manufacturer’s details. Common call-outs are for holes left by a change of layout and unsealed gaps around fire door frames, on linear gaps, pipe & cable gaps and service penetrations.
In London, a commercial job often starts with access: loading bays, building rules and lifts. For a building in Coombe Hill, we agree timings and access before anything starts, and room-by-room programmes can be planned where needed.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Surface by surface
Door frames
Behind most architraves is a gap between frame and wall. Where it’s open, we seal it to the product’s details for that gap size so the architrave can be refitted.
Plasterboard walls
Many fire-resisting walls in flats, offices and conversions are plasterboard. We use a product tested in that kind of wall for each gap size.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Include hidden areas like risers in routine checks
- File the fire-stopping record where your assessor can find it
- Flag any open gap you spot round a pipe or cable
- Include fire stopping when you schedule refits
Any fire seal that’s cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.
Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.
What we do, step by step
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes anything from a few hours to several days, depending on how many gaps there are, including the tidy-up. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- We plan the order of work and access, floor by floor or flat by flat.
- Old, damaged or unsuitable sealant is removed.
- Gaps are cleaned of dust and loose material.
- We apply and tool the sealant to the product’s tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Preparing for the visit
- Mention any tricky access
- Tell us about any water getting in
- Mention any parking rules near the property

What affects the cost of fire rated sealant
We quote each job individually. This is what makes a difference:
- The product the joint needs
- How much old sealant there is and how hard it is to remove
- How many areas need sealing
- How much there is to do
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
Asking for a quote
Before you ask for a quote, have a think about:
- The problem you’ve noticed
- If someone has resealed it before
- The address or postcode of the job
- Photos by email, if that is easy

For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Why act early in Coombe Hill
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. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Coombe Hill.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will go through it with you.

Fire rated sealant around Coombe Hill
Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed. 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.
For buildings such as St John the Baptist, older buildings that have had new heating or wiring often have service gaps worth checking. Coombe Hill is in London, so parking needs planning: let us know about parking bays, permits or a driveway. Letting a property close to Norbiton station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
