New build mastic in Aith
We work in new homes and on new-build sites across Aith. One shower or a whole phase of plots, the method does not change: remove, clean, prime where needed, then a neat new bead. We work on plot handovers, windows & doors and skirting & floors, and common reasons people get in touch are new-build shower sealant that has already split and frame joints opening as the plaster dries.
New homes in smaller Scottish places are often single plots, self-builds or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
Every job comes with a 12-month guarantee.

FAQs for Aith

Yes. Aith is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland, including the islands, where work is planned around ferry crossings. Let us know about access, parking and anything unusual about getting there when you book.
Do you cover Aith for new build mastic?

Are you fully insured?
Yes, we’re fully insured for domestic and commercial work.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
Who should fix failed sealant in a new build?
While the snagging or warranty period runs, the builder should be your first contact. If it isn’t sorted, or keeps failing, get in touch with us.
How long will you be here?
Typically it takes a few hours in a single home. Larger jobs naturally take longer.
Why has my new-build shower seal failed already?
New homes dry out and move in their first couple of years, and sealant is often rushed onto dusty, unprimed surfaces. Either can make it fail early.
What should I tell you?
A short description and the location, with photos by email if possible. We will ask anything else we need to know.
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Resist patching a failed seal with a tube from the DIY shop
- Don’t wait for the house to settle if water is getting through
- Report sealant problems to your builder during the snagging period
- Keep water off fresh sealant until it has cured
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry and can be resealed later.
Early snagging is easier snagging. Small faults turn into leaks if left.
How the visit works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for most snagging lists, longer for a run of plots. For a place like Aith, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- Each joint is checked for movement before work begins.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Move anything stored near the joints
- Keep children and pets away from the work area

Related advice
What new build mastic looks like in Aith
Aith is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, 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.
Whether the job is in Aith itself or nearby, the right material for each joint matters as much as a neat finish. Around Aith, as everywhere, new build mastic is only as good as the preparation behind it.

How we quote for new build mastic
We don’t publish a price list, because no two jobs are the same. What we look at:
- The type of sealant required
- Any working-time requirements on site
- The old material and how stubborn it is
- How many areas need sealing
What you pay reflects the work, not guesswork. That’s why we ask a few questions first.
What we need to know
To help us quote quickly, please include:
- The type of property
- If someone has resealed it before
- Photos by email, if that is easy
- What the problem is, such as mould, gaps, leaks or cracking
For new build mastic in Aith, email us at info@mrmastic.co.uk. Tell us what the problem is and where, and you’ll get a clear quote before any work starts.
What sealant work can’t fix
Sealant isn’t the answer to every problem, and we’ll tell you before any work starts. It won’t solve:
- Leaking fittings rather than failed sealant
- A tray or bath that isn’t properly supported, until it’s fixed
- Deciding who is responsible under a builder’s warranty
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.

Different surfaces, different methods
Plot handovers
Send us the schedule and any sealant specification for a quote. Sealant work across the plot is covered as agreed.
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 in a matching colour.
Landlords, agents and businesses in Aith
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.
Landlords and letting agents in Aith can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
Why it’s worth doing now in Aith
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
