How to look after the new joints
A little care helps the new joints last. Our advice:
- Have rotten timber repaired before new mastic goes in
- Avoid heavy scraping on the mastic joint
- Renew mastic before redecorating the windows
- Make sure water runs off the sill
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.
About our sand mastic in Chapelton
Traditional burnt sand mastic blends with stone and brick surrounds. It suits period and listed homes where a modern sealant bead would stand out. If you are dealing with mastic round period door frames that has failed and window mastic to renew ahead of painting, we can put it right.
Mastic can only go onto a dry joint, so outside work in Chapelton depends on the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
Whatever the size of the job, you get the same 12-month guarantee in Chapelton and across South Lanarkshire.

Sand mastic in Chapelton: local notes
Chapelton is in the west of Scotland, which is wetter than the east, which means the mastic around older windows and doors has to cope with a lot of rain. 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.
If you let a flat or house near Hamilton Central station, older sash windows in a rental need their mastic kept sound to keep the weather out.
Chapelton is about 4 miles south of Hamilton, in South Lanarkshire. Chapelton gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee.

Do you need sand mastic in Chapelton?
Scraping and sanding before painting can loosen old mastic. Many people find it crumbling when they prepare the windows.
The most common problems we see are:
- Draughty sash windows at the surround
- Mastic worn away on windows facing the weather
- Cracked mastic round a front door frame
- Gaps between timber frames and stone or brick
For an older house near a landmark such as Chapelton, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

When something else is needed
Sealant is not the answer to every problem, and we will tell you before we start. Sealant will not put right:
- Decayed frames that need repair
- Decisions on consent for listed homes
- Cracked or broken glass
If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer before you book.

What the job involves on each surface
Sash and case windows
The mastic round a sash window is on show so we finish it carefully.
Brick reveals
An open joint at a brick reveal lets weather in. New mastic seals the gap.
Why act early in Chapelton
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic is the traditional material and blends with the stone or brick. In a place like Chapelton, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
