New build mastic in Moulsham, done properly
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. If you’re dealing with internal frame sealant that has split and gaps behind new kitchen upstands, we can put it right.
If you’ve bought a new home in or near Moulsham, the first year or two is a good time to check the sealant. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
You get a 12-month guarantee, the same in Moulsham as everywhere else we work.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Common problems we fix in Moulsham
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly.
Common reasons people contact us are:
- Joints pulling apart as timber shrinks
- New-build shower sealant that has already split
- Smeared, uneven beads picked up at snagging
- Internal frame sealant that has split
Around Moulsham, as everywhere, new build mastic is only as good as the preparation behind it.

What happens on the day
At the end, we look at the finished work together. The visit itself generally takes a few hours for most snagging lists, longer for a run of plots, depending on how much there is to do.

- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.

Related advice
Why it’s worth doing now in Moulsham
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it won’t bond to the old layer. A lasting seal starts with removing the old one completely. Homes in smaller places like Moulsham can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.

What sealant work cannot fix
We will not take on work that will not last, so these are the limits:
- Leaking fittings rather than failed sealant
