Looking after it afterwards

How long the joints last depends on use and care. Here’s what we suggest:

  • Look at the sealant regularly in the first couple of years
  • Report sealant problems to your builder during the snagging period
  • Get a leaking seal dealt with right away
  • Don’t seal over failed sealant yourself

Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it, which can damage the surface.

A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small.

New build mastic in West Kilbride

Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. Both get the same care over preparation. We work on windows & doors, bathrooms & en suites and skirting & floors, and common reasons people get in touch are frame joints opening as the plaster dries and joints pulling apart as timber shrinks.

Timber frame is common in newer Scottish homes, and it settles over the first years, which shows as gaps at skirtings and floor joints. In older homes, timber floors move through the year too.

Big or small, it’s backed by our one-year guarantee in West Kilbride and across North Ayrshire.

Why act early in West Kilbride

The builder is usually the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In a place like West Kilbride, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.

Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, send an email to info@mrmastic.co.uk and we will give you an honest view and a quote.

Around West Kilbride, as everywhere, new build mastic is only as good as the preparation behind it.

Signs you need new build mastic in West Kilbride

New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. As it does, timber shrinks and joints open.

Signs it’s time to call us include:

  • Messy sealant that spoils new finishes
  • Cracked caulk along new skirting
  • New-build shower sealant that has already split
  • Frame joints opening as the plaster dries

For new homes near West Kilbride station, it’s worth checking the sealant early, while snags are still fresh.

Should I go to my builder first?

Your builder, if you are still in their snagging or warranty period. If that doesn’t work out, we’re happy to quote.

What sealant work cannot fix

A few problems are outside what sealant work can do:

  • Leaking fittings rather than failed sealant

  • Damaged fittings that need replacing

Advice

Surface by surface

Skirting and floors

Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.

Plot handovers

We work through plots to your schedule, sealing each room ready for handover. Joints are prepared properly before sealing.
