New build mastic in East Claydon
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. We work on bathrooms & en suites, windows & doors and kitchens, and people most often call us about sealant that never bonded to the surface and gaps opening as the house dries out and settles.
Older homes in small places like East Claydon often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or drop us an email.

DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Common problems we fix in East Claydon
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints are not always given time to dry before the sealant goes on.
Most people get in touch when they notice one of these:
- Cracked sealant around new window and door frames
- Gaps behind new kitchen upstands
- Gaps between new skirting and floors
- Shower seals failing in the first year or two
In and around East Claydon, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

When it is not the sealant
A few problems are outside what sealant work can do:
- Structural cracks in walls or ceilings
- Your warranty claim itself, which is between you and the builder
- Leaking fittings rather than failed sealant

Leave it or put it right?
DIY kits don’t solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Around East Claydon, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

- 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.
Before we arrive

Advice
Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Watch for new gaps as the house dries out
- Raise failed sealant with the developer while you are covered
- Record problems with dated photos
- Wipe joints with warm soapy water
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.
