New build mastic for homes and businesses in Herstmonceux
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that is reasonable, but a failed shower or bath seal shouldn’t wait. We work on bathrooms & en suites, skirting & floors and kitchens, and common reasons people get in touch are leaking shower tray seals in a new home and internal frame sealant that has split.
Older homes in small places like Herstmonceux often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
All our work comes with a one-year guarantee, wherever you are in East Sussex.

What happens if it’s left?
Small cosmetic gaps can wait for the house to settle, but water getting through can’t. Not sure whether yours can wait? You can phone 0345 464 0079 or send us an email with a few pictures and we will tell you. In a small place like Herstmonceux, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Leaving a failed joint normally makes the job bigger, not smaller. If you’re not sure whether it needs doing, phone 0345 464 0079 or send us an email and we will give you an honest view and a quote.

Common problems we fix in Herstmonceux
A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart.
Any of these means the joints need attention:
- Cracked caulk along new skirting
- Sealant work across a run of new homes
- Beads laid onto grit and dust from the build
- Shower seals failing in the first year or two
For jobs in and around Herstmonceux, choosing the right material for each joint is as important as a tidy finish.

Looking after it afterwards
So the new joints stay in good condition:
- Open a window or run the fan after bathing
- Photograph failed sealant before it’s redone
- Act quickly if a seal starts to leak
- Check bath and shower seals every few months as the house settles
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents.
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.
FAQs for Herstmonceux
Is there a guarantee on new build mastic in Herstmonceux?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Do you cover smaller places like Herstmonceux?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do plot mastic on a new development?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send us the plot schedule and we’ll quote.
Can tenants book the work?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
When is the best time to reseal in a new build?
That depends on the joint. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
What do you need from me for a quote?
A short description and the location, plus pictures if you have them. If we need more, we will ask.

How the job changes by surface
Kitchens
As a new house dries, worktops and walls shift a little, which opens gaps along the back. We reseal them with a flexible sealant.
Windows and doors
A draught at a new window can be a missed or failed joint. We check and reseal the frame edges.
