Sand mastic for homes and businesses in Waterside
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It suits period and listed homes, where modern sealant can look out of place. We work on sash and case windows, timber door frames and period & listed homes, and the jobs we see most are cracked mastic round a front door frame and failed mastic on an exposed elevation.
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.
Each job carries a 12-month guarantee, whatever its size.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Get any rot dealt with first
- Ask the planning authority about consent for listed or conservation-area homes
- Make sure water runs off the sill
- Avoid heavy scraping on the mastic joint
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.

For anyone letting property in or around Waterside, several properties can go on one quote. Send us the addresses and the work at each, and pictures by email help.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
When something else is needed
In fairness, there are a few things sealant will not fix:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Cracked or broken glass
- Damaged stone surrounds

Why deal with it now?
New mastic over crumbling mastic will not hold. Raking out and preparing the joint gives it a sound base so the new work lasts. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll go through it with you.

What we are called out for in Waterside
Some old mastic was never deep enough. Mastic that’s too thin cracks and drops out so we make sure the new mastic is the right thickness.
It’s worth asking for a quote if you see:
- Draughty sash windows at the surround
- Mastic round period door frames that has failed
- Silicone on a period window that looks wrong
- Failed mastic on an exposed elevation
For site and facilities teams at buildings such as Kirkintilloch High School, the mastic around its windows and doors needs looking after like any other building’s.

What we do, step by step
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes anything from a few hours to a full day, depending on how many windows from start to finish. Outside jobs in Waterside need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Getting ready for the visit
- Clear the area around the work
- Let us know about parking restrictions
- Let us know if you’ve seen damp or leaks

Is it possible to paint over sand mastic?

How long does sand mastic take to go off?
It forms a skin fairly soon, then hardens over a longer period. Timing depends on the weather and the joint.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.

Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
