New build mastic in Roberton
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks rather than sitting on a layer of grit. If you have new-build shower sealant that has already split and kitchen sealant that has pulled off the wall, we can put it right.
For a place like Roberton, the journey and access are planned in advance. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
A one-year guarantee comes with the work, just as it does everywhere we cover.

New build mastic around Roberton

What we’re called out for in Roberton
The first winter with the heating on dries a new home quickly. Gaps open along skirting, frames and worktops and cracks appear in the sealant.
Signs it’s time to call us include:
- Worktop and upstand sealant coming away
- Frame joints opening as the plaster dries
- Leaking shower tray seals in a new home
- Gaps opening as the house dries out and settles
Around Roberton, as everywhere, new build mastic is only as good as the preparation behind it.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep water off fresh sealant until it has cured
- Avoid scourers and strong chemicals on sealant
- Keep pictures and emails about snagging items
- Resist patching a failed seal with a tube from the DIY shop
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.
Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you, so raise it early.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Advice
Why act early in Roberton
DIY kits don’t solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.
