East Kilbride New Build Mastic

New build mastic in East Kilbride, done properly
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. Typical jobs include smeared, uneven beads picked up at snagging and cracked sealant around new window and door frames, on show homes, plot handovers and bathrooms & en suites.
In a town like East Kilbride, older streets sit alongside newer estates. Newer homes need snagging; older ones need their joints renewing.
Big or small, it’s backed by our one-year guarantee.

Why act early in East Kilbride
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. Scottish weather finds any gap, and in a town like East Kilbride, failed outside joints soon let damp into walls. Inside, a failed seal around a bath or shower lets water into floors and ceilings.
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.

New homes and floors in East Kilbride
Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up. The west of Scotland is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain.
For new homes near East Kilbride station, it’s worth checking the sealant early, while snags are still fresh.

East Kilbride questions
Is new build mastic in East Kilbride guaranteed?
All our work, in East Kilbride and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Can you help a landlord with a rental near East Kilbride station?
Yes, rental work is part of what we do. You can send an email to info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before work begins.
Where do you work from?
We work from Crawley. Our applicators cover East Kilbride.
Do you use white or clear sealant?
Most bathroom joints are white or clear, but other colours are available. We match the colour to the finish.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Can you reseal over the builder’s sealant?
No. New silicone will not bond to old silicone, so it soon lifts and traps water. We cut the old bead out completely.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints.
What the job involves on each surface
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in and baths are filled before sealing.
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens, food-safe where it’s needed.
When to call us in East Kilbride
On many sites, sealant goes on in the final rush before handover. Joints aren’t always cleaned of dust or primed, so the bead never bonds properly.
It’s worth asking for a quote if you see:
- New-build shower sealant that has already split
- Kitchen sealant that has pulled off the wall
- Joints pulling apart as timber shrinks
- Messy sealant that spoils new finishes
In and around East Kilbride, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
