Common problems we fix in Amisfield
Most of it is simply age. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.
The most common problems we see are:
- Gaps where the frame meets the masonry
- Tired mastic found when preparing windows for paint
- Patchy fillers round a sash window
- A silicone bead on a sash window that spoils the look
For an older house near a landmark such as Tinwald Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What sand mastic looks like in Amisfield
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Letting a property close to Dumfries station? Then any sash windows need sound mastic to keep draughts and rain out.

Can you do sand mastic in Amisfield?
Yes. Our work covers the whole of Scotland, and Amisfield is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we’ll give you a clear price.
Will you come out to Amisfield?
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.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
How long does sand mastic take?
Typically it takes anything from a few hours to a full day, depending on how many windows. Bigger jobs take longer, and we’ll say how long yours will take.
Where are you based?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do you have insurance?
Yes. We are fully insured, and we can confirm the details when we quote.
Does someone need to be in?

How to look after the new joints
So the new joints stay in good condition:
- Renew mastic before redecorating the windows
- Don’t run silicone over sand mastic
- Check the mastic when you check the paintwork
- Take care around the mastic when scraping paint
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.
Leave it or put it right?
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. In a place like Amisfield, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.
