Sand mastic for sash & case windows in College Milton, South Lanarkshire
Professional sand mastic in and around College Milton, with every bit of old sealant taken out first and a 12-month guarantee.
- Draughts and rain around sash boxes
- A silicone bead on a sash window that spoils the look
- Mastic worn away on windows facing the weather
Sand mastic in College Milton, done properly
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. We rake it out and renew it and tidies the surround. If you are dealing with failed mastic on an exposed elevation and mastic dropping out of the joint, we can put it right.
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.
Big or small, you get the same 12-month guarantee.

FAQs for College Milton
Do you cover smaller places like College Milton?

Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Is consent needed for window work on a listed home?
It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like but the decision is theirs.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Do you offer different sealant colours?
Most of the time, yes. We’ll explain which colours are available and agree one before we start.
Is it possible to take out silicone and use sand mastic instead?
Often, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.

Signs you need sand mastic in College Milton
Rain on the window surround works into any crack and loosens it further. Windows facing the weather tend to go first.
Any of these means the joints need attention:
- Silicone on a period window that looks wrong
- Crumbling sand mastic round a window
- Mastic that needs renewing before redecorating
- Patchy fillers round a sash window
Managing a site like Duncanrig Secondary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Aftercare tips
To keep the joints looking good and working properly:
- Make sure water runs off the sill
- Look over the window mastic once a year
- Find out about consent before window work on a listed home
- Have rotten timber repaired before new mastic goes in
Leave the new mastic unpainted, as traditional guidance advises. If you are redecorating, ask us first.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.
