New Build Mastic in Blackwood

- Plot mastic for developers ahead of handover
How we handle new build mastic in Blackwood
We never seal over a failed new-build bead. Fresh silicone cannot bond to the old layer, so the joint is cut out, cleaned, dried and resealed. We work on windows & doors, show homes and kitchens, and the jobs we see most are gaps behind new kitchen upstands and skirting joints opening in the first winter.
Timber frame is common in newer Scottish homes, and it settles over the first years, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
You get a 12-month guarantee, the same in Blackwood as everywhere else we work.

For landlords and businesses
For anyone letting property in or around Blackwood, several properties can be quoted together. Send us the addresses and the work at each.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
What the job involves on each surface
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens suited to the job.
Why act early in Blackwood
A quick bead over the top of the old sealant can look fine at first, but it will not bond to the old layer. A lasting seal starts with removing the old one completely. In an older home around Blackwood, damp from a failed joint can get into timber and plaster.
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Avoid scourers and strong chemicals on sealant
- Watch for new gaps as the house dries out
- Don’t seal over failed sealant yourself
- Follow the cure time we give you
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing so moisture does not sit on the sealant.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
