New build mastic for homes and businesses in An Tairbeart
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 since hurried prep is behind a lot of new-build failures. Common call-outs are for cracked sealant around new window and door frames and leaking shower tray seals in a new home, on plot handovers, show homes and bathrooms & en suites.
Around smaller Scottish places like An Tairbeart, 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.
There’s a 12-month guarantee on every job.

DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Wipe joints with warm soapy water
- Look at the sealant regularly in the first couple of years
- Open a window or run the fan after bathing
- Get a leaking seal dealt with right away
Keep pictures of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
Your questions about new build mastic in An Tairbeart
Is new build mastic in An Tairbeart guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Do you cover An Tairbeart for new build mastic?
Yes. Our work covers the whole of Scotland, and An Tairbeart is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear quote.
What information do you need?
Tell us what needs doing and where, plus photos if you have them. If we need more, we will ask.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can you work from my snagging list?
Yes. Photos of each sealant item help us quote. If something is not sealant, we will say so.
Where are you based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
New build mastic in An Tairbeart: local notes
An Tairbeart 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. Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.
In and around An Tairbeart, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. For jobs in and around An Tairbeart, choosing the right material for each joint is as important as a tidy finish.

Leave it or put it right?
DIY kits don’t solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Call for a quick quote and we will explain what it covers.
