New-build mastic & snagging in Clo Mhuillin, Highland
Specialist new build mastic for Clo Mhuillin: the right sealant, proper preparation and a neat finish. Ask us for a quick quote.
- Cracks appearing as a new home settles
- Frame joints opening as the plaster dries
- Untidy sealant flagged on a snagging list
Why deal with it now?
Small cosmetic gaps can wait for the house to settle, but water getting through can’t. If you’re unsure which you have, send an email to info@mrmastic.co.uk with pictures and we will give you a straight answer. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.

- An ARBOMaster approved applicator

New build mastic in Clo Mhuillin, done properly
Snagging sealant properly means taking the failed bead out completely. New silicone won’t bond to old silicone, so the joint is cut out, cleaned, dried and resealed. Common call-outs are for untidy sealant flagged on a snagging list and plot mastic for developers ahead of handover, across kitchens, windows & doors and plot handovers.
Timber frame is common in newer Scottish homes, and it settles over the first years, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

What new build mastic looks like in Clo Mhuillin
Clo Mhuillin is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.
Around Clo Mhuillin, as everywhere, new build mastic is only as good as the preparation behind it. Whether the job is in Clo Mhuillin itself or nearby, the right material for each joint matters as much as a neat finish.

How it works
You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the work takes anything from a few hours to several days, depending on the number of plots in most cases. For a place like Clo Mhuillin, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.

Advice
Different surfaces, different methods
Show homes
Tired or marked sealant in a show home can be renewed. We cut it out and reseal neatly.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant that suits the frame.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Looking after it afterwards
After the cure time, these simple habits help:
- Keep photos and emails about snagging items
- Follow the cure time we give you
- Check bath and shower seals every few months as the house settles
- Clean sealant with mild detergent, not abrasives
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry and can be resealed later.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.
Clo Mhuillin: your questions answered
Is Clo Mhuillin within the area you cover?
Yes, we do. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What guarantee comes with new build mastic in Clo Mhuillin?

What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. Then send an email to info@mrmastic.co.uk.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Do you have insurance?
Yes. Mr Mastic is fully insured.
Do you remove the old sealant?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Do you work through snagging lists?
Yes. Send us the sealant items on the list, with photos if you can and we’ll give you a quote. We’ll flag anything that needs another trade.
Can you reseal over the builder’s sealant?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before we start.
What sealant work can’t fix
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Plumbing faults behind the sealant
- Structural cracks in walls or ceilings
- Deciding who is responsible under a builder’s warranty
If you’re not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer before booking.
