The most common problems we see are:
- Gaps between new skirting and floors
- Sealant that never bonded to the surface
- Gaps behind new kitchen upstands
- Plot mastic for developers ahead of handover
For new homes near Crowborough station, it’s worth checking the sealant early, while snags are still fresh.

What else we do in Woolbridge
How to look after the new joints
To keep the joints looking good and working properly:
- Photograph failed sealant before it’s redone
- Avoid scourers and strong chemicals on sealant
- Resist patching a failed seal with a tube from the DIY shop
- Wait for the cure time before using a resealed shower
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and the new finishes intact.
Landlord and commercial work in Woolbridge
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.
We work for landlords and agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
How the job changes by surface
Kitchens
Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. We reseal them with a flexible sealant.
Skirting and floors
As timber and screed dry, skirting and floors shift. Caulk cracks; a flexible sealant moves with it painted or coloured to suit.
What new build mastic looks like in Woolbridge
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Why deal with it now?
The builder is generally the first port of call while the snagging or warranty period runs. If it keeps failing or is not dealt with, we can reseal it properly. Older cottages and farmhouses around Woolbridge can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
