New build mastic in Glyndebourne
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly. If you are dealing with gaps between new skirting and floors and joints pulling apart as timber shrinks, we can put it right.
In a village or hamlet like Glyndebourne, 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.
You are covered for a year from the day we finish. If anything is not right with it, phone 0345 464 0079 or email us.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Look at the sealant regularly in the first couple of years
- Act quickly if a seal starts to leak
- Avoid running a DIY bead over the old one
- Keep pictures and emails about snagging items
Avoid standing on the rim of the bath or the edge of the tray. If a bath or tray moves when you stand in it, get it looked at.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and the new finishes intact.
What happens on the day

All told, the work takes anything from a few hours to several days, depending on the number of plots.

- We cut out every bit of the failed or messy sealant.

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Will you come out to Glyndebourne?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.
Why has my new-build shower seal failed already?
Lots of new homes see sealant crack early as timber and plaster dry out. Poor preparation at handover adds to it.
Can you match the sealant colour to my new kitchen or bathroom?
Most bathroom joints are white or clear, but other colours are available. We match the colour to the finish.
How long does new build mastic take?
As a guide, most jobs take a few hours in a single home. Larger jobs naturally take longer, and we will tell you how long to expect.
Can tenants book the work?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Will there be a smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
