About our new build mastic in Ashford Hill
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you’re still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. If you have kitchen sealant that has pulled off the wall and joints pulling apart as timber shrinks, we can help.
Somewhere as small as Ashford Hill, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
You are covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs 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.
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Raise failed sealant with the developer while you are covered
- Don’t wait for the house to settle if water is getting through
- Ventilate bathrooms well, especially in the first year
- Follow the cure time we give you
Don’t stand on the bath edge or the lip of the tray while the sealant cures. 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 affects the cost of new build mastic
The price is agreed before any work begins. It takes into account:
- The type of sealant required
- Whether old sealant or filler has to be cut out
- Whether the work is at height

A failed joint rarely gets cheaper to fix by waiting. If you are unsure, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

What we’re called out for in Ashford Hill
Sealant is often one of the last jobs before handover. Joints aren’t always cleaned of dust or primed, so the bead never bonds properly.
People generally contact us when they notice something like this:
- Smeared, uneven beads picked up at snagging
- Sealant that never bonded to the surface
- Gaps opening as the house dries out and settles
- Worktop and upstand sealant coming away
For new homes near Midgham station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before you book

- How the joint is cleaned and prepared
