New build mastic in An Tairbeart, done properly
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. We are often asked to deal with plot mastic for developers ahead of handover and beads laid onto grit and dust from the build, on skirting & floors, show homes and windows & doors.
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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
For landlords and businesses
Landlords and agents in An Tairbeart can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll give you a quote.
Why deal with it now?
The builder is generally the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. 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.

Your questions about new build mastic in An Tairbeart
Will you come out to An Tairbeart?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Arrochar & Tarbet station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we will send you a clear quote.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Will you just run a new bead over the existing one?
No. New silicone won’t bond to old silicone, so sealing over the top fails quickly. The old sealant always comes out first.
How long does new build mastic take?
A typical job takes a few hours in a single home, including preparation and clearing up. Your quote will say how long we expect yours to take.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover An Tairbeart.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
What does new build mastic cost?
Size, access and the old material all affect the cost. Call for a quick quote and we’ll talk you through it.

Advice
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Record problems with dated photos
- Clean sealant with mild detergent, not abrasives
- Look at the sealant regularly in the first couple of years
- Wait for the cure time before using a resealed shower
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.
