Sand mastic for homes and businesses in Crutherland
Sand mastic doesn’t last for ever, leaving gaps round the window. Renewing it closes the gap and tidies the surround. Common call-outs are for draughty sash windows at the surround and old cement repairs round a window that have failed, on brick reveals, stone surrounds and sash and case windows.
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.
We stand behind the work with a 12-month guarantee, so you’re covered after we’ve gone.

Why it’s worth doing now in Crutherland
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and finishes neatly against the masonry. Around Crutherland, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.

How the visit works
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours per window, depending on the condition of the joints. Outside jobs in Crutherland need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
How to prepare
- Mention any sign-in or site rules at work premises
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks

FAQs for Crutherland
Do you cover smaller places like Crutherland?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Is Crutherland in your area for sand mastic?
Yes, Crutherland is within the area we cover. Our work covers the whole of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job.
Do you offer different sealant colours?
We will suggest a colour to suit the surroundings. The product needed can limit the range.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

What does sand mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we will talk you through it.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we are using and why.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Crutherland homes and the weather
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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
Rented homes near East Kilbride station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

Do you need sand mastic in Crutherland?
Age is the main cause. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
These are the problems we’re asked about most:
- Patchy fillers round a sash window
- Crumbling sand mastic round a window
- Gaps round a timber door in stone or brick
- Gaps where the frame meets the masonry
Schools such as Mount Cameron Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Can I do it myself?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Have rotten timber repaired before new mastic goes in
- Inspect the joints round the windows every year or so
- Renew mastic before redecorating the windows
- Ask the planning authority about consent for listed or conservation-area homes
Leave the new mastic alone while it firms up. It forms a skin fairly soon, but takes longer to harden fully.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
What we cannot put right
A few problems are outside what sealant work can do:
- Planning or listed building consent (your local planning authority decides)
- Masonry that needs repairing
- Timber that has rotted
