New build mastic in Prestonville
Across Prestonville, we work for both new-home owners and the builders handing those homes over. Whether it’s one en suite or a run of plots, the method is the same: remove, clean, prime where needed, then a neat new bead. We work on plot handovers, windows & doors and kitchens, and the jobs we see most are smeared, uneven beads picked up at snagging and skirting joints opening in the first winter.
Homes around Prestonville 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. The sealant at skirtings and thresholds has to suit the floor it meets.
All of our work is guaranteed for twelve months.

Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Raise failed sealant with the developer while you’re covered
- Keep water off fresh sealant until it has cured
- Wipe joints with warm soapy water
- Resist patching a failed seal with a tube from the DIY shop
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.

Joints and finishes in Prestonville homes
Prestonville is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Around Prestonville, as everywhere, new build mastic is only as good as the preparation behind it. For new homes near Preston Park station, it’s worth checking the sealant early, while snags are still fresh.

Landlord and commercial work in Prestonville
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Why act early in Prestonville
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot. In an older home around Prestonville, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and agree the price before starting.
Why us?
- An ARBOMaster approved applicator
- Old sealant always removed completely
- Anti-fungal silicone where joints get wet
- White, clear, grey or another colour, product permitting

How the job changes by surface
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens, food-safe where it’s needed.
Windows and doors
