How to look after the new joints
Good habits help new joints last longer. A few tips:
- Record problems with dated pictures
- Wait for the cure time before using a resealed shower
- Put sealant faults on your snagging list early
- Resist patching a failed seal with a tube from the DIY shop
Do not stand on the bath edge or the lip of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak over time.
New build mastic in Whitehill, done properly
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first. If you are dealing with plot mastic for developers ahead of handover and kitchen sealant that has pulled off the wall, we can help, on kitchens, plot handovers and bathrooms & en suites alike.
Homes around Whitehill range from older cottages to newer houses, and their floors range just as widely, from timber that moves with the seasons to tiles laid on concrete. Skirting and threshold joints need a sealant that suits the floor.
There’s a 12-month guarantee on every job, whatever its size.

Questions from Whitehill
Is Whitehill in your area for new build mastic?
Yes. Our work covers London and the South East, and Whitehill is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing.
Is Whitehill within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
What should I tell you?
A short description and the location, with pictures by email if possible. We’ll ask anything else we need to know.
Can you do several jobs on one visit?
Yes. Just list everything you need and we’ll quote it together.
Can you match the sealant colour to my new kitchen or bathroom?
White and clear are the most common, but other colours are available. We choose one to suit the room before we begin.
How long will you be here?
Most jobs take a few hours for most snagging lists, longer for a run of plots. We’ll confirm how long when we quote.
Do you take on second-fix sealing for builders?
Yes. We take on second-fix sealant work across new plots. We clean and prime joints properly to keep callbacks down.
Is it worth resealing while the house is still settling?
It depends on whether water is getting through. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
What the job involves on each surface
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Skirting and floors
Wet-area floor joints need a flexible seal. We seal them with a sealant suited to wet areas.
Why deal with it now?
Small cosmetic gaps can wait for the house to settle, but a leaking seal cannot. If you are unsure which you have, ring 0345 464 0079 or drop us an email with photos and we’ll tell you. Around Whitehill, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or drop us an email.
