Problem with your window and door surrounds in Melrose? We remove the old material, prepare the joints and seal them properly.
- Old cement repairs round a window that have failed

When to call us in Melrose
Paint, silicone or cement used over old mastic causes problems. They don’t suit the joint and we normally remove them.
People normally contact us when they notice one of these:
- Weathered mastic on the most exposed windows
- Modern sealant on a period surround
- Tired mastic found when preparing windows for paint
- Gaps between timber frames and stone or brick
In and around Melrose, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

Sand mastic for homes and businesses in Melrose
We renew sand mastic around sash windows and doors set in stone or brick. The old mastic is raked out, and new mastic is applied and shaped by hand. Common call-outs are for window mastic to renew ahead of painting and failed mastic on an exposed elevation, across stone surrounds, sash and case windows and period & listed homes.
In and around a place like Melrose, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
There’s a 12-month guarantee on every job, whatever its size.

Looking after it afterwards
A little care helps the new joints last. We recommend:
- Avoid patching sand mastic with silicone
- Check with your local planning authority if your home is listed
- Inspect the joints round the windows every year or so
- Ask us before painting near the mastic
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Cracked or broken glass
- Planning or listed building consent (your local planning authority decides)
- Sash cords, weights and draught-proofing of the sashes
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly.

Your questions about sand mastic in Melrose
Is Melrose in your area for sand mastic?

Can you help a landlord with a rental near Tweedbank station?

How long does the job take?
It depends on the size of the job, but as a guide it takes a few hours per window, depending on the condition of the joints. We’ll tell you when we quote.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
Are you an approved applicator?

Do you guarantee sand mastic work?

What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Is sand mastic better than silicone for my windows?
That depends on your windows. Period windows in stone or brick usually suit sand mastic, while modern frames normally get a flexible sealant.
What happens on the day
You do not need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the work takes anything from a few hours to a full day, depending on how many windows for a typical job. Somewhere like Melrose may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Mention any sign-in or site rules at work premises
- Mention any tricky access
- Keep children and pets away from the work area

What sand mastic looks like in Melrose
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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
If you let a flat or house near Tweedbank station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Around Melrose
The closest station to Melrose is Tweedbank station, about 1.5 miles west of the centre. Other landmarks nearby include Commendators House Museum (under half a mile east) and Castle Holydean (2.4 miles south). For a walk, there’s Eildon Hill North and Bemersyde Moss.
Why act early in Melrose
An open joint round the frame lets weather in. Left, water can reach the timber and the wall so renewing it early protects the window. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.
