New build mastic in Stone Corner, done properly
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. If you have cracked caulk along new skirting and second-fix sealing on new plots, we can help, on kitchens, bathrooms & en suites and show homes alike.
For a small place like Stone Corner, the journey and access are planned in advance, and the work itself is the same as on any site.
Big or small, it’s backed by our one-year guarantee.

Do you need new build mastic in Stone Corner?
A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart, and sealant that cannot keep up splits.
Most people get in touch when they notice one of these:
- Leaking shower tray seals in a new home
- Sealant that never bonded to the surface
- Gaps behind new kitchen upstands
- Cracked caulk along new skirting
If you’ve bought a new home near Appledore (Kent) station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before you book
- Is VAT in the price?
- How the surfaces are prepared before sealing
- Which colour the sealant will be
- Which sealant they’ll use, and why
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What the job involves on each surface
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk painted or coloured to suit.
Windows and doors
On new builds, external frame sealant can be patchy. We reseal it with a weatherproof, flexible sealant.
Landlords, agents and businesses in Stone Corner
Landlords and agents in Stone Corner can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.

Questions from Stone Corner
Is Stone Corner in your area for new build mastic?
Yes, Stone Corner is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing, and we will send you a clear quote.
Is Stone Corner within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us.
When is the best time to reseal in a new build?
Where water is getting through, do not wait. Small gaps that are just cosmetic can be resealed once movement has slowed.
Do you work for landlords and businesses?
Yes, often. Several properties can be quoted together, and between tenancies is a good time for the work.
Can you do plot mastic on a new development?
Yes. We work through plots to your schedule ready for handover. Tell us the plots and the joints involved and we will quote.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Looking after it afterwards
So the new joints stay in good condition:
- Wait for the cure time before using a resealed shower
- Wipe joints with warm soapy water
- Watch for new gaps as the house dries out
- Put sealant faults on your snagging list early
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents.
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.
The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours in a single home and we leave things clean and tidy. Somewhere like Stone Corner needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you’re given the cure time.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we’re working on
- For business premises, tell us about site rules or sign-in
