How we handle new build mastic in Wanborough
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly. If you’re dealing with kitchen sealant that has pulled off the wall and beads laid onto grit and dust from the build, we can help, on windows & doors, kitchens and plot handovers alike.
Older homes in small places like Wanborough often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Every job is covered by a 12-month guarantee, wherever you are in Surrey.

How to look after the new joints
Aftercare is simple:
- Avoid scourers and strong chemicals on sealant
- Report sealant problems to your builder during the snagging period
- Watch for new gaps as the house dries out
- Ventilate bathrooms well, especially in the first year
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents, which can damage the surface.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left.
For landlords and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll quote.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.

Surface by surface
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. A proper reseal keeps water in the tray.
Windows and doors
On new builds, external frame sealant can be patchy. It’s resealed with an exterior sealant suited to the frame and wall.
What we cannot put right
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Leaking fittings rather than failed sealant
- Deciding who is responsible under a builder’s warranty
- Baths and trays that move too much for sealant to cope with
If you are not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.

Do you need new build mastic in Wanborough?
On many sites, sealant goes on in the final rush before handover. Joints aren’t always cleaned of dust or primed, so the bead never bonds properly.
Any of these means the joints need attention:
- Smeared, uneven beads picked up at snagging
- Internal frame sealant that has split
- Cracks appearing as a new home settles
- Sealant work across a run of new homes
In and around Wanborough, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
