How we handle new build mastic in Tetsworth
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. Typical jobs include smeared, uneven beads picked up at snagging and cracked sealant around new window and door frames, on windows & doors, show homes and kitchens.
In a village or hamlet like Tetsworth, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Different surfaces, different methods
Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it.
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. The joint is stripped back before the new bead goes in.
Leave it or put it right?
Small cosmetic gaps can wait for the house to settle, but a leaking seal can’t. If you’re unsure which you have, call 0345 464 0079 or email us with pictures and we’ll tell you. Around Tetsworth, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Looking after it afterwards
After the cure time, these simple habits help:
- Open a window or run the fan after bathing
- Record problems with dated photos
- Put sealant faults on your snagging list early
- Clean sealant with mild detergent, not abrasives
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant.

Where do you work from?

Can new sealant go on top of the old bead?
No. Fresh silicone does not stick to the old layer, so it soon lifts and traps water. The old sealant always comes out first.
