New build mastic for homes and businesses in Inverkeithing
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. In both, preparation makes the difference. If you are dealing with messy sealant that spoils new finishes and sealant that never bonded to the surface, we can help, whatever the surface.
Many newer homes in Scotland are timber-framed and settle as they dry out, so skirting and floor joints can open up. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
Our work is backed for twelve months.

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Open a window or run the fan after bathing
- Wipe joints with warm soapy water
- Don’t wait for the house to settle if water is getting through
- Follow the cure time we give you
Follow the cure time we give you before the area gets wet. Most silicones need around a day.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small and the new finishes intact.
What the job involves on each surface
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Each joint is cleaned and primed where needed to keep callbacks down.
Skirting and floors
New homes often develop a gap between skirting and floor. We seal it with a flexible sealant that copes with the movement.
Honest limits
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Leaks from pipes, valves or wastes, which need a plumber
- Cracking that points to a structural problem
- Disputes or warranty claims with your builder
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly.
Surfaces we seal

Questions from Inverkeithing
Do you cover smaller places like Inverkeithing?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is Inverkeithing in your area for new build mastic?
Yes. Our work covers the whole of Scotland, and Inverkeithing is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
Is it worth resealing while the house is still settling?
It depends on whether water is getting through. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
How long does the job take?
Most jobs take a few hours in a single home, including the preparation. Your quote will say how long we expect yours to take.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Is it normal for sealant to crack in a new home?
Lots of new homes see sealant crack early, because the house is drying and settling. Poor preparation at handover adds to it.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.

Should I try it myself first?
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. Everything old must be removed first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
