Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. Around Miabhaig, water from a failed joint in an older stone home can soak into timber and plaster.

New build mastic in Miabhaig, done properly
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. We work on skirting & floors, kitchens and show homes, and people most often call us about cracks appearing as a new home settles and leaking shower tray seals in a new home.
Around smaller Scottish places like Miabhaig, new homes tend to be single plots or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
We stand behind the work with a one-year guarantee, so you are covered after we’ve gone.

Landlord and commercial work in Miabhaig
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
Common problems we fix in Miabhaig
A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open, and sealant that cannot keep up splits.
Any of these means the joints need attention:
- Sealant that never bonded to the surface
- Shower seals failing in the first year or two
- Cracks appearing as a new home settles
- Skirting joints opening in the first winter
For jobs in and around Miabhaig, choosing the right material for each joint is as important as a tidy finish.

FAQs for Miabhaig
Is there a guarantee on new build mastic in Miabhaig?
All our work, in Miabhaig and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Do you cover Miabhaig for new build mastic?
Yes, Miabhaig is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Can you do several jobs on one visit?
Yes. Just list everything you need and you will get one quote.
Will you just run a new bead over the existing one?
No. Fresh silicone does not stick to the old layer, so it soon lifts and traps water. The old sealant always comes out first.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover Miabhaig, along with the rest of our area.
Is it worth resealing while the house is still settling?
It depends on whether water is getting through. A leaking shower or bath seal should be redone straight away, but cosmetic gaps can wait for movement to slow.
New build mastic in Miabhaig: local notes
Miabhaig is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Island jobs need planning around ferries and the weather, so the more notice, the better.
Around Miabhaig, as everywhere, new build mastic is only as good as the preparation behind it.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Open a window or run the fan after bathing
- Wait for the cure time before using a resealed shower
- Look at the sealant regularly in the first couple of years
- Avoid scourers and strong chemicals on sealant
Avoid standing on the rim of the bath or the edge of the tray. If a bath or tray moves when you stand in it, get it looked at.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Honest limits
We’d rather tell you now than do work that won’t last, so these are the limits:
- Deciding who is responsible under a builder’s warranty
- Structural cracks in walls or ceilings
- Leaks from pipes, valves or wastes, which need a plumber
If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer.
What we seal
- Skirting & floors
- Bathrooms & en suites
- Windows & doors
- Plot handovers
- Kitchens
- Show homes
