New build mastic in Brands Hill, done properly
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. Typical jobs include cracked caulk along new skirting and new-build shower sealant that has already split, across show homes, plot handovers and skirting & floors.
In a village or hamlet like Brands Hill, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Aftercare tips
After the cure time, these simple habits help:
- Avoid running a DIY bead over the old one
- Watch for new gaps as the house dries out
- Open a window or run the fan after bathing
- Clean sealant with mild detergent, not abrasives
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents as they wear the bead.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and protects the rest of the house.
Leave it or put it right?
A hairline gap at a skirting can wait, but a leaking seal can’t. Not sure whether yours can wait? You can ring 0345 464 0079 or email us with a few photos and we will give you a straight answer. Older cottages and farmhouses around Brands Hill can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not guesswork. That is why we ask about the job first.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
