Common questions in Cambridge Heath
Is parking a problem for a job in Cambridge Heath?
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.
Do you work in hotels near Cambridge Heath?
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.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Cambridge Heath.
Can tenants book the work?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
How we handle fire rated sealant in Cambridge Heath
Landlords, managing agents and facilities teams use us for the sealant items on a fire risk assessment for buildings in Cambridge Heath. Send us the list or the survey and we will quote for the fire-rated sealant work on it. We work on linear gaps, door frames and plasterboard & masonry, and people most often call us about gaps flagged on a fire risk assessment and unsealed gaps around fire door frames.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. For a building in Cambridge Heath, we agree timings and access before anything starts, and room-by-room programmes can be planned where needed.
There’s a 12-month guarantee on every job.

What we do, step by step
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes from a few hours to a few days, depending on the number of gaps and the access. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Cambridge Heath. It helps if you can point us to a visitor permit or a bay close to the door.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Old or unsuitable sealant is cut out and the gap cleaned.
- Where the tested detail needs backing or fill, we fit it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Finally, we list where we worked and what we used, for your records.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children

Signs you need fire rated sealant in Cambridge Heath
Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It looks sealed, but it is not fire-rated.
Keep an eye out for these signs:
- Fire stopping disturbed by later work
- Gaps filled with a product that is not fire-rated
- Linear gaps at the head of walls
- Door frames with gaps between frame and wall
Schools such as Mowlem Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

Fire rated sealant in Cambridge Heath: local notes
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. Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed.
As a London address, Cambridge Heath can be tricky for parking: let us know about parking bays, permits or a driveway. For buildings such as St James-the-Less, gaps around pipes and cables are worth checking after any building work there.

Surface by surface
Linear gaps
A linear joint may need to allow for movement as well as fire. We choose a product and depth that suit the gap and the movement from the manufacturer’s details.
Plasterboard walls
Many fire-resisting walls in flats, offices and conversions are plasterboard. The sealant has to be one tested in plasterboard for each gap size.

Why deal with it now?
A quick fill with any sealant to hand is not fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, 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, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Cambridge Heath.

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Plan fire stopping into any work that goes through walls or floors
- Make resealing part of every contractor’s brief
- Include hidden areas like risers in routine checks
- Report cracked or damaged seals as soon as you notice them
Tell other trades that the gaps have been sealed, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.
Open gaps do not only matter in a fire: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.
