How we handle new build mastic in Whistley Green
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. If you’re dealing with leaking shower tray seals in a new home and untidy sealant flagged on a snagging list, we can help, whatever the surface.
Older homes in small places like Whistley Green often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
Whatever the size of the job, it’s backed by our one-year guarantee.

What we cannot put right
Some problems need a builder, plumber or other trade rather than us:
- Movement caused by a poorly fitted tray or bath
- Cracked trays, tiles or worktops
- Your warranty claim itself, which is between you and the builder
If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.

What the job involves on each surface
Kitchens
Sink joints are wet all the time. We use a sealant suited to kitchens.
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out and baths are filled before sealing.
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Avoid running a DIY bead over the old one
- Record problems with dated photos
- Wipe joints with warm soapy water
- Don’t wait for the house to settle if water is getting through
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers to help keep mould away.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small.
Why it’s worth doing now in Whistley Green
A tube of sealant from the DIY shop won’t fix the cause: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. Around Whistley Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
