Why deal with it now?
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry so renewing it early protects the window. In a place like Kilmelford, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.

How we handle sand mastic in Kilmelford
Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties, where modern sealant can look out of place. If you have weathered mastic on the most exposed windows and gaps between timber frames and stone or brick, we can help.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Each job carries a 12-month guarantee, large or small.

Windows and doors in Kilmelford
Kilmelford is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
Homes close to Kilmelford Parish Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Kilmelford: your questions answered
Is Kilmelford in your area for sand mastic?
Yes, Kilmelford is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job, and we will send you a clear quote.
Does living near the coast affect sand mastic in Kilmelford?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can landlords and businesses book you?
Yes, we do. Domestic, commercial and hotel work are all part of what we do.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Are you insured?
Yes. We are fully insured for domestic and commercial work.
Can you match the sealant colour?
Generally, yes. White, clear and grey are common, and other colours are available, and we will agree it with you first.
Should I check with the council before work on a listed or conservation-area home?
Yes, it’s worth checking. Ask your local planning authority whether consent is needed for work on a listed home or in a conservation area.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.

What happens on the day
There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes a few hours per window, depending on the condition of the joints for a typical job. Outdoor work around Kilmelford depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not affected.

Do you need sand mastic in Kilmelford?
Previous repairs in cement or silicone often trap water or crack away. They do not move with the timber, and they normally need raking out.
Any of these means the joints need attention:
- Mastic that needs renewing before redecorating
- Gaps between timber frames and stone or brick
- Gaps round a timber door in stone or brick
- Draughts and rain around sash boxes
Around Kilmelford, as everywhere, sand mastic is only as good as the preparation behind it.
Questions to ask before you book
