Merton Park Fire Rated Sealant
Our applicators work in Merton Park on intumescent and fire-rated sealant around gaps, frames and service penetrations. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Holes left by a change of layout
- Fire stopping disturbed by later work
- Fire seals that have cracked with movement
Leave it or put it right?
Waiting for the next refit can leave a gap open for years. Sealing the gap now is a contained job on its own and needn’t wait for anything else. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Merton Park, the repair is bigger than a sealant job.
Doing several joints on one visit is usually more efficient than separate visits. We will send you a clear quote for the lot.
Why us?
- We never seal over old sealant
- Experience in homes, commercial sites and hotels
- 180+ five-star Google reviews
- Quality sealants from Arbo and Everbuild

Fire rated sealant for homes and businesses in Merton Park
Bigger jobs can be worked through in stages, flat by flat or floor by floor, noting the locations and products as we go. It gives you a list to keep with the building’s fire safety documents. Common call-outs are for sealant items on a fire risk assessment action list and seals cut through by electricians, plumbers or data installers, on pipe & cable gaps, service penetrations and door frames.
In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. For managing agents and building owners in Merton Park, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

Fire rated sealant in Merton Park: local notes
There are hotels and other places to stay in and around Merton Park. Hotel work can be planned room by room, with out-of-hours working 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, 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.
For landlords with property near South Merton station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Merton Park is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Can I do it myself?
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, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
FAQs for Merton Park
Do you work for landlords with property near South Merton station?
Yes. We work for letting agents and landlords as well as householders. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
Do you work for hotels and guest houses in Merton Park?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Is intumescent sealant the same as fire-rated sealant?
An intumescent material expands when it’s heated. Many fire-rated sealants work this way, but not all, and the choice depends on the gap.
Where is Mr Mastic based?
We are based in Crawley, and we work across South East England, London and Scotland.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
What does fire rated sealant cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
How long does fire rated sealant take?
Most jobs take anything from a few hours to several days, depending on how many gaps there are, including the preparation. We will confirm how long when we quote.
Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will quote.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Signs you need fire rated sealant in Merton Park
Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.
If you can see any of these, it’s time to have the joints looked at:
- Open gaps behind door architraves
- Ordinary sealant used where a fire-rated product was needed
- Fire seals that have cracked with movement
- Seals cut through by electricians, plumbers or data installers
Managing a site like Merton Park Primary School? Then fire-stopping around service openings should be restored whenever new services go in.
What your quote should include
- When the joint can take water or movement
- The length of the guarantee
- Whether VAT is included
- Who does the work, and how experienced they are
What we do, step by step
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a handful of gaps, and longer for a whole building. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Merton Park. A visitor permit or a nearby bay makes the visit run more smoothly.
- Access to each area is agreed so the work can run in order.
- Old, damaged or unsuitable sealant is removed.
- Gaps are cleaned of dust and loose material.
- 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.
How to prepare
- Let us know if you’ve seen damp or leaks
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Include hidden areas like risers in routine checks
- Keep the record of products and locations with your fire safety documents
- Plan fire stopping into any work that goes through walls or floors
- Don’t fill fire-stopping gaps with ordinary foam or silicone
File the record of locations and products with your fire safety paperwork. It helps whoever checks the building next.
Open gaps don’t only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
