- Leaking shower tray seals in a new home
- Gaps between new skirting and floors
- Kitchen sealant that has pulled off the wall
Looking after it afterwards
Looking after new joints is easy:
- Follow the cure time we give you
- Watch for new gaps as the house dries out
- Avoid scourers and strong chemicals on sealant
- Use the extractor fan every time you shower
Keep photos of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in saves a harder job later.
New build mastic in Mountain Street
Snagging sealant properly means taking the failed bead out completely. Fresh silicone can’t bond to the old layer, so the joint is cut out, cleaned, dried and resealed. We work on kitchens, show homes and bathrooms & en suites, and people most often call us about cracked caulk along new skirting and cracks appearing as a new home settles.
Somewhere as small as Mountain Street, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
Every job is covered by a one-year guarantee.

Signs you need new build mastic in Mountain Street
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
Most people get in touch after spotting something like this:
- Plot mastic for developers ahead of handover
- Kitchen sealant that has pulled off the wall
- Leaking shower tray seals in a new home
- Cracked caulk along new skirting
For new homes near Chilham station, it’s worth checking the sealant early, while snags are still fresh.

Why it’s worth doing now in Mountain Street
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Older cottages and farmhouses around Mountain Street can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and agree the price before starting.
Why book with us
- A choice of colours where the product allows
- Old sealant always removed completely
