New build mastic in Elphinstone, done properly
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a seal that’s letting water through needs doing now. We work on skirting & floors, show homes and windows & doors, and people most often call us about sealant applied over dusty or wet surfaces and internal frame sealant that has split.
Work in a place like Elphinstone is planned ahead, journey included. Inside work goes ahead in any weather; outside mastic needs a dry day.
All of our work is guaranteed for twelve months, in Elphinstone and everywhere else we cover.

When to call us in Elphinstone
Sealant is often one of the last jobs before handover. Joints are not always cleaned of dust or primed, so the bead never bonds properly.
Most people get in touch when they notice one of these:
- Gaps between new skirting and floors
- Shower seals failing in the first year or two
- Sealant that never bonded to the surface
- Gaps behind new kitchen upstands
Around Elphinstone, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before you book
- How the joint is cleaned and prepared
- How long the guarantee is
- How the colour is chosen
- How long to leave it before use
DIY versus a professional finish
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, and the work is guaranteed for a year.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Joints and finishes in Elphinstone homes
Elphinstone is within about 3 miles of the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.
If you’ve bought a new home near Prestonpans station, the sealant around baths, showers and frames is worth checking in the first year or two.

Aftercare tips
So the new joints stay in good condition:
- Keep water off fresh sealant until it has cured
- Wipe joints with warm soapy water
- Open a window or run the fan after bathing
- Put sealant faults on your snagging list early
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
How the job changes by surface
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. They get a flexible, water-resistant sealant.
Plot handovers
Send us the schedule and any sealant specification and we’ll quote. We seal bathrooms, kitchens, frames and floors as agreed.
