New build mastic in Friston
We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. We work on kitchens, skirting & floors and bathrooms & en suites, and common reasons people get in touch are beads laid onto grit and dust from the build and cracked caulk along new skirting.
Homes around Friston range from older cottages to newer houses, and their floors range just as widely, from timber that moves with the seasons to tiles laid on concrete. Skirting and threshold joints need a sealant that suits the floor.
Each job carries a 12-month guarantee, whatever its size.

When something else is needed
We’ll always be straight with you, so here’s what sealant cannot fix:
- Baths and trays that move too much for sealant to cope with
- Leaking fittings rather than failed sealant
- Deciding who is responsible under a builder’s warranty

New build mastic around Friston
Friston is within about 1 mile of the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For new homes near Eastbourne station, it’s worth checking the sealant early, while snags are still fresh. In and around Friston, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

What else we do in Friston
How it works
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. It usually takes anything from a few hours to several days, depending on the number of plots. For a job in Friston, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Each joint is checked for movement before we start.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
How to prepare
- Keep children and pets away from the work area
- Tell us about any previous sealing or DIY attempts
- Mention any leaks or damp you’ve noticed

Advice
Aftercare tips
After the cure time, these simple habits help:
- Avoid running a DIY bead over the old one
- Raise failed sealant with the developer while you are covered
- Use the extractor fan every time you shower
- Avoid scourers and strong chemicals on sealant
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day to cure enough for use.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant.
Why deal with it now?
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot. Around Friston, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.
