Fire-rated sealant in Moor Park, Greater London
We cover Moor Park for intumescent and fire-rated sealant around gaps, frames and service penetrations. Old sealant removed completely, joints prepared properly.
- Gaps left after a refit or conversion
- Fire seals that have cracked with movement
- Damaged fire sealant left by other trades
Fire rated sealant in Moor Park, done properly
Door frame gaps, linear joints and holes around services all have their own details. Measuring the gap and checking what it’s made of comes first, then the sealant goes in to the depth the product’s details set. We work on door frames, linear gaps and pipe & cable gaps, and the jobs we see most are gaps filled with a product that isn’t fire-rated and fire seals that have cracked with movement.
In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. In Moor Park, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
All of our work is guaranteed for twelve months.

Common problems we fix in Moor Park
Sometimes the wrong product was used from the start: ordinary expanding foam, standard silicone or decorators’ caulk where a fire-rated seal was needed. It looks sealed, but it is not fire-rated.
People usually contact us after spotting one of these:
- Damaged fire sealant left by other trades
- Gaps filled with a product that is not fire-rated
- Gaps around pipes and cables through fire-resisting walls
- Old fire sealant that has split or come away
If you let a flat or house near Rickmansworth station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
Questions to ask before booking

Why it’s worth doing now in Moor Park
Leaving a gap until a refurbishment comes round can mean years with it open. On its own, sealing it now is a small job that does not depend on other work. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Moor Park, the repair is bigger than a sealant job.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or drop us an email.

Moor Park: your questions answered
Do you cover Moor Park for fire rated sealant?
Yes. We work across London and the South East, and Moor Park is part of that. Just ring 0345 464 0079 or email us with a few details of the job.
Is parking an issue for fire rated sealant in Moor Park?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Will it make a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
Where do you work from?
Mr Mastic is based in Crawley. We cover Moor Park and the rest of Greater London.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.
How much does fire rated sealant cost in Moor Park?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
What we can’t put right
We will always be straight with you, so here’s what new sealant won’t do:
- Fire risk assessments, which need a qualified assessor
- A wall that is not a fire-resisting element to begin with
- Large holes that need a different fire-stopping system
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.

Workplaces and buildings in Moor Park
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. Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange.
Managing a site like St Martins School Northwood? Then fire-stopping around service openings should be restored whenever new services go in. If you look after a church, hall or community building such as Holy Trinity Church, gaps around pipes and cables are worth checking after any building work there.

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Surface by surface
Linear gaps
Head-of-wall gaps are often hidden above suspended ceilings. We work along the whole run.
Door frames
Behind most architraves is a gap between frame and wall. We seal any open gap to the product’s tested details so the architrave can be refitted.
The process
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for a handful of gaps, and longer for a whole building. In Moor Park, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- We remove any old or unsuitable filler and clean the gap.
- Backing or fill is fitted where the product’s tested detail calls for it.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Finally, we list where we worked and what we used, for your records.
