About our window mastic in Clo Mhuillin
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. Typical jobs include white mastic on grey or black frames and draughts coming in around windows and doors, across uPVC windows, window sills and patio & French doors.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
All our work is covered by our one-year guarantee.

Clo Mhuillin questions
Can you do window mastic in Clo Mhuillin?
Yes. We work across all of Scotland, and Clo Mhuillin is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
Does the coastal weather in Clo Mhuillin affect outside sealant?
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.
Do you guarantee window mastic?
Yes. All our work carries a 12-month guarantee, and we are fully insured.
Can you do several jobs on one visit?
Of course. Doing several areas at once is generally more efficient.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
How do I get a quote for window mastic in Clo Mhuillin?
Size, access and the old material all affect the cost. Call for a quick quote and we’ll talk you through it.
Can tenants book the work?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Can resealing stop a draught around my window?
It will if the frame joint is the problem. We find where the air is coming from before we reseal.
What we are called out for in Clo Mhuillin
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
Keep an eye out for these signs:
- Black, perished sealant on frames
- White mastic on grey or black frames
- Cracked sealant at the sill ends
- Draughty joints inside around the window
Homes close to Ardgour Parish Church include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.
Before booking anyone
- Whether you can choose the colour
- Whether they seal over old material or remove it
- What the quote includes, VAT included or not
- What preparation is included

Advice
What window mastic looks like in Clo Mhuillin
Clo Mhuillin is within about 1 mile of 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 window and door frames, especially on the side facing the sea. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
Around Clo Mhuillin, as everywhere, window mastic is only as good as the preparation behind it.

How the job changes by surface
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We seal the frame and let you know about anything else.
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. It comes out, deep gaps get backing rod and the joint is resealed.
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
