Different surfaces, different methods
Period and listed homes
Materials matter on listed and conservation-area homes. Sand mastic is often the preferred finish.
Brick reveals
Loose mastic comes out and deep gaps are packed before pointing.
How we handle sand mastic in Longriggend
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, brick reveals and stone surrounds, and the jobs we see most are silicone on a period window that looks wrong and failed mastic on an exposed elevation.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain.
Every job comes with our 12-month guarantee, wherever you are in North Lanarkshire.

Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
We work for letting agents and landlords as well as homeowners. Resealing between tenancies keeps a property looking cared for.
What we are called out for in Longriggend
Timber swells and shrinks with the weather. That movement opens up the mastic joint little by little.
People generally contact us when they notice something like this:
- Mastic worn away on windows facing the weather
- Tired mastic found when preparing windows for paint
- Open joints round the window box
- Mastic round period door frames that has failed
Rented homes near Caldercruix station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

- Is VAT in the price?
- Are they insured?
- How the surfaces are prepared before sealing
- How the colour is chosen
How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Ask us before painting near the mastic
- Keep modern sealant off the mastic
- Renew mastic before redecorating the windows
- Clear gutters so water doesn’t pour onto the windows
Don’t run silicone over the new mastic. If you see a crack, ask us to take a look rather than patching it.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.

How the visit works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to a full day, depending on how many windows. Outside jobs in Longriggend need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Getting ready for the visit
- Let us know about parking restrictions
- Let us know about earlier repairs to the joints
- Let us know about stairs, lifts or work at height

DIY versus a professional finish
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.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
