What sand mastic looks like in Killen
Killen is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Whether the job is in Killen itself or nearby, the right material for each joint matters as much as a neat finish.

Sand mastic in Killen, done properly
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. We work on brick reveals, stone surrounds and timber door frames, and common reasons people get in touch are weathered mastic on the most exposed windows and gaps round a timber door in stone or brick.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
What happens if it’s left?
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad and new mastic seals them. 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.
Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.

Killen questions
Is sand mastic in a coastal place like Killen any different?
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.
Do you cover Killen for sand mastic?
Yes. We work across all of Scotland, and Killen is part of that. You can email us at info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear quote.
How do I get a quote for sand mastic in Killen?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Where do you work from?
Our base is Crawley. We work across South East England, London and Scotland.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Is consent needed for window work on a listed home?
Speak to your local planning authority before work starts. Sand mastic is often favoured as like for like but the decision is theirs.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Do you have insurance?
Yes. We are fully insured.
