About our sand mastic in Devonburn
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder and built up by hand. On older homes, it suits the building far better than silicone. We are often asked to deal with silicone on a period window that looks wrong and window mastic to renew ahead of painting, on stone surrounds, brick reveals and sash and case windows.
Outdoor sealant needs a dry surface, so window work around Devonburn is planned around the weather. Let us know about access to every frame, including any upstairs.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

Your questions about sand mastic in Devonburn
Is Devonburn within the area you cover?
Yes, Devonburn is covered. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is Devonburn in your area for sand mastic?
Yes, Devonburn 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, and we’ll give you a clear price.
Do you work for letting agents?
Yes, we do. We work in homes, commercial premises and hotels.
What do you need from me for a quote?
Let us know what needs doing and where. We will ask anything else we need to know.
Is sand mastic better than silicone for my windows?
Sand mastic usually suits period timber windows best. Modern frames normally suit a flexible sealant, and we’ll explain why.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Should I check with the council before work on a listed or conservation-area home?
Checking first is sensible. Your local planning authority can say if consent is needed for work on a listed home or in a conservation area.
Can you match the sealant colour?
We help you choose a colour that suits. The choice depends on the product the joint needs.
What affects the cost of sand mastic
For a quick quote, just ask. What matters most is:
- Access and height
- Which sealant suits the joint
- Working hours on commercial sites
- How much old sealant there is and how hard it is to remove
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, send an email to info@mrmastic.co.uk for an honest opinion and a quote.
Asking for a quote
When you call or email, it’s useful to know:
- Whether it has been sealed before
- How many joints, rooms or windows are involved
- Access, such as stairs, a lift or height
- Photos by email, if that is easy
We quote each job on its own, so the first step is telling us about yours. Just send an email to info@mrmastic.co.uk with the details and send pictures if you have them.
Honest limits
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Decayed frames that need repair
- Planning or listed building consent (your local planning authority decides)
- Broken panes
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before you book.

- Tenement windows
- Sash and case windows
- Stone surrounds
- Timber door frames
- Brick reveals
Surface by surface
Tenement and terrace windows
Where a building is shared, window work may involve neighbours so it’s worth checking responsibilities.
Stone surrounds
Old stone surrounds are often uneven, so the gap is not the same all the way round. Sand mastic is shaped by hand to suit.
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

What else we do in Devonburn
Landlords, agents and businesses in Devonburn
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
Why deal with it now?
New mastic over crumbling mastic won’t hold. Raking out and preparing the joint gives it a sound base so the new mastic stays put. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will explain what it covers.
What you get with us
- Homes, businesses and hotels
- A 12-month guarantee on all work
- An ARBOMaster approved applicator
- Neat joints and a tidy finish

Devonburn homes and the weather
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. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
For site and facilities teams at buildings such as Lesmahagow High School, the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Lanark station, cracked sand mastic around sash windows lets in the draughts tenants complain about. For an older house near a landmark such as Lesmahagow Old Parish Church, the joint between an old wall and a newer frame is usually the first place rain gets in.
