New build mastic in Jealott's Hill
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you are still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. Common call-outs are for kitchen sealant that has pulled off the wall and frame joints opening as the plaster dries, on show homes, windows & doors and kitchens.
Around Jealott's Hill, older homes often have timber floors that move through the year, 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.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Wait for the cure time before using a resealed shower
- Report sealant problems to your builder during the snagging period
- Avoid running a DIY bead over the old one
- Photograph failed sealant before it’s redone
Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you.

DIY versus a professional finish
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.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
How the job changes by surface
Windows and doors
A draught at a new window can be a missed or failed joint. We check and reseal the frame edges.
Kitchens
Sink joints are wet all the time. A kitchen sealant goes in there.
What we’re called out for in Jealott's Hill
Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and can tear.
Common reasons people contact us include:
- Leaking shower tray seals in a new home
- Beads laid onto grit and dust from the build
- Skirting joints opening in the first winter
- Worktop and upstand sealant coming away
In and around Jealott's Hill, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
