About our new build mastic in Wash Water
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over using the right product for each joint. We’re often asked to deal with cracked caulk along new skirting and gaps behind new kitchen upstands, across windows & doors, bathrooms & en suites and plot handovers.
Somewhere as small as Wash Water, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
Our work is backed for twelve months.

What happens if it’s left?
A hairline gap at a skirting can wait, but water getting through cannot. If you’re unsure which you have, ring 0345 464 0079 or email us with pictures and we’ll tell you. In a small place like Wash Water, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.

Signs you need new build mastic in Wash Water
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and the sealant may split.
Common reasons people contact us are:
- Shower seals failing in the first year or two
- Messy sealant that spoils new finishes
- Gaps between new skirting and floors
- Joints pulling apart as timber shrinks
In and around Wash Water, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Can you match the sealant colour to my new kitchen or bathroom?

Is there a guarantee?
Yes, for a year. If anything is not right with the work within the year, let us know and we’ll sort it.

Honest advice matters more to us than a booking, so here’s what new sealant will not do:

Aftercare tips
Good habits help new joints last longer. A few tips:
- Wait for the cure time before using a resealed shower
- Avoid running a DIY bead over the old one
- Look at the sealant regularly in the first couple of years
- Avoid scourers and strong chemicals on sealant
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small and protects the rest of the house.
What the job involves on each surface
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one that suits the frame.
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing and primer used where needed.
New homes and floors in Wash Water
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For new homes near Newbury station, it’s worth checking the sealant early, while snags are still fresh.
