New build mastic in Westwood
We never seal over a failed new-build bead. Fresh silicone cannot bond to the old layer, so the joint is cut out, cleaned, dried and resealed. We work on plot handovers, show homes and bathrooms & en suites, and common reasons people get in touch are gaps between new skirting and floors and sealant that never bonded to the surface.
In a village or hamlet like Westwood, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

New build mastic in Westwood: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Resist patching a failed seal with a tube from the DIY shop
- Follow the cure time we give you
- Ventilate bathrooms well, especially in the first year
- Report sealant problems to your builder during the snagging period
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents.
Report failed sealant to the builder while you are in the snagging period. Once it ends, the repair may be down to you, so raise it early.

Do you need new build mastic in Westwood?
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart, and sealant that cannot keep up splits.
These are the problems we are asked about most:
- Sealant work across a run of new homes
- Frame joints opening as the plaster dries
- Gaps opening as the house dries out and settles
- Gaps behind new kitchen upstands
If you’ve bought a new home near Longfield station, the sealant around baths, showers and frames is worth checking in the first year or two.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Why it’s worth doing now in Westwood
Resealing everything on a snagging list in one visit is normally simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times for the lot. Older cottages and farmhouses around Westwood can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and agree the price before starting.
Why us?
- A 12-month guarantee on all work
- Anti-fungal silicone where joints get wet
- A sealant colour to suit the surroundings
- Over 20 years’ experience
