About our new build mastic in Cheriton
We work in new homes and on new-build sites across Cheriton. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. We work on bathrooms & en suites, windows & doors and kitchens, and common reasons people get in touch are joints pulling apart as timber shrinks and kitchen sealant that has pulled off the wall.
Around Cheriton, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Big or small, it’s backed by our 12-month guarantee in Cheriton and across Hampshire.

What sealant work can’t fix
It helps to know what we cannot do:
- Cracking that points to a structural problem
- Your warranty claim itself, which is between you and the builder
- Leaks from pipes, valves or wastes, which need a plumber
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think.

What the job involves on each surface
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Joints are prepared properly before sealing.
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. They get a flexible, water-resistant sealant.

Is it normal for sealant to crack in a new home?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.
What happens on the day
Before we leave, we go over the finished joints with you. The visit itself normally takes anything from a few hours to several days, depending on the number of plots, depending on the amount of work. Somewhere as small as Cheriton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- 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.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Let us know about parking restrictions
- Where the joints are inside, avoid wetting them before we arrive

Related advice
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Wipe joints with warm soapy water
- Report sealant problems to your builder during the snagging period
- Keep photos and emails about snagging items
- Act quickly if a seal starts to leak
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing to help keep mould away.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.

Signs you need new build mastic in Cheriton
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and the sealant may split.
The problems people generally mention when they call include:
- Gaps opening as the house dries out and settles
- Shower seals failing in the first year or two
- Untidy sealant flagged on a snagging list
- Gaps behind new kitchen upstands
For jobs in and around Cheriton, choosing the right material for each joint is as important as a tidy finish.
