Pitshanger questions
Is parking an issue for new build mastic in Pitshanger?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Do you cover Pitshanger for new build mastic?
Yes. We work across London and the South East, and Pitshanger is part of that. Just ring 0345 464 0079 or email us with a few details of the job.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or send us an email.
Where do you work from?
Mr Mastic is based in Crawley. We cover Pitshanger and the rest of Greater London, along with the rest of our area.
Can you work from my snagging list?
Yes. Send it with photos and we’ll quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Is it normal for sealant to crack in a new home?
Lots of new homes see sealant crack early as timber and plaster dry out. Rushed application on dusty surfaces makes it worse.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little.
New build mastic in Pitshanger
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly instead of bonding to the dust. We’re often asked to deal with messy sealant that spoils new finishes and internal frame sealant that has split, across bathrooms & en suites, show homes and windows & doors.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, and new homes need their plot mastic finished properly before handover, in Pitshanger and beyond.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

New homes and floors in Pitshanger
Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For new homes near Castle Bar Park station, it’s worth checking the sealant early, while snags are still fresh.

What the job involves on each surface
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. They get a flexible, water-resistant sealant.
Plot handovers
Taking time over preparation reduces return visits. Dust from the build is removed first.
Landlord and commercial work in Pitshanger
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.

What sealant work can’t fix
In fairness, there are a few things sealant won’t fix:
- Deciding who is responsible under a builder’s warranty
- Leaking fittings rather than failed sealant
- Settlement cracks that need a surveyor
If you are not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer before booking.

What we do, step by step
Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours in a single home. In a London area like Pitshanger, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
How to prepare
- Mention any tricky access
- Tell us if parking is tricky
- For indoor joints, keep the area dry beforehand if you can

Leave it or put it right?
A hairline gap at a skirting can wait, but water getting through can’t. Not sure whether yours can wait? You can ring 0345 464 0079 or drop us an email with a few photos. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Pitshanger, the repair is bigger than the sealant job would have been.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
