Your questions about sand mastic in Tolastadh bho Thuath
Does living near the coast affect sand mastic in Tolastadh bho Thuath?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Can you do sand mastic in Tolastadh bho Thuath?
Yes. We work across all of Scotland, and Tolastadh bho Thuath is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
What guarantee comes with the work?
Our 12-month guarantee applies on every job.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Are you insured?
Yes, we’re fully insured for domestic and commercial work.
Can I choose the sealant colour?
We’ll suggest a colour to suit the surroundings. The product needed can limit the range.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we’re using and why.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.

What sand mastic looks like in Tolastadh bho Thuath
Tolastadh bho Thuath is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Tolastadh bho Thuath is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out.
Around Tolastadh bho Thuath, as everywhere, sand mastic is only as good as the preparation behind it. For jobs in and around Tolastadh bho Thuath, choosing the right material for each joint is as important as a tidy finish.

What we do, step by step
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes anything from a few hours to a full day, depending on how many windows, depending on the size of the job. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Before we arrive
- Let us know about earlier repairs to the joints
- Let us know if you’ve seen damp or leaks
- Tell us if parking is tricky

Looking after it afterwards
Aftercare is simple:
- Ask us before painting near the mastic
- Get any rot dealt with first
- Sort the mastic before the decorators arrive
- Check the mastic when you check the paintwork
Avoid painting over the new mastic, which is the traditional advice. If you are redecorating, ask us first.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
If you do try it yourself, take your time over the 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.
Different surfaces, different methods
Period and listed homes
Period homes look their best with traditional materials.
Stone surrounds
The stone is treated with care when the old mastic comes out.
