Kingston Vale New Build Mastic
Plot mastic for developers and snagging failed sealant in new homes for homes and businesses in Kingston Vale and across Greater London. Fully insured, ARBOMaster approved and guaranteed for a year.
- Internal frame sealant that has split
- Cracks appearing as a new home settles
- Second-fix sealing on new plots
How we handle new build mastic in Kingston Vale
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that is reasonable, but a failed shower or bath seal shouldn’t wait. If you are dealing with frame joints opening as the plaster dries and worktop and upstand sealant coming away, we can help, whatever the surface.
Across London, commercial floors have movement joints that break down under heavy foot traffic, while new homes need a neat, sound finish around frames, baths and kitchens before handover.
There’s a 12-month guarantee on every job, large or small.

New build mastic in Kingston Vale: local notes
Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
As a London address, Kingston Vale can be tricky for parking: let us know about parking bays, permits or a driveway.

Why it’s worth doing now in Kingston Vale
Small cosmetic gaps can wait for the house to settle, but water getting through can’t. Not sure whether yours can wait? You can ring 0345 464 0079 or send us an email with a few photos and we will give you a straight answer. In a flat in Kingston Vale, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before work begins, so you know where you stand.

What we’re called out for in Kingston Vale
When the heating goes on in the first winter, the house dries fast. Gaps open along skirting, frames and worktops and cracked sealant shows up.
Common reasons people contact us include:
- Plot mastic for developers ahead of handover
- Kitchen sealant that has pulled off the wall
- Cracked sealant around new window and door frames
- Skirting joints opening in the first winter
If you’ve bought a new home near Raynes Park station, the sealant around baths, showers and frames is worth checking in the first year or two.

Aftercare tips
After the cure time, these simple habits help:
- Resist patching a failed seal with a tube from the DIY shop
- Raise failed sealant with the developer while you are covered
- Act quickly if a seal starts to leak
- Photograph failed sealant before it’s redone
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers so moisture doesn’t sit on the sealant.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and protects the rest of the house.

What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes a few hours for most snagging lists, longer for a run of plots, including the tidy-up. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children
How to get a quote
