Sand mastic in Brechin
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. We work on sash and case windows, brick reveals and tenement windows, and the jobs we see most are mastic dropping out of the joint and patchy fillers round a sash window.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill.
There’s a 12-month guarantee on every job, whatever its size.

How the visit works
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for a single window, longer for several for a typical job. For a place like Brechin, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Before we arrive
- Let us know about stairs, lifts or work at height
- Keep children and pets away from the work area
- Let us know about parking restrictions

Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. We renew it the same way as on windows.
Period and listed homes
A traditional finish suits a period property, and sand mastic is one of them.
Why deal with it now?
If you are redecorating, renew the mastic first. Painting over failed mastic does not seal it, and the new mastic is traditionally left unpainted. Around Brechin, 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.
What you pay reflects the work, not guesswork. That’s why we ask about the job first.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Brechin homes and the weather
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
Schools such as Brechin High School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. In and around Brechin, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

FAQs for Brechin
Is there a guarantee on sand mastic in Brechin?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Is Brechin within the area you cover?
Yes. Brechin is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
I rent my home. Can I book you?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will tell you what we are using.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures.
How much does sand mastic cost in Brechin?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Is it possible to take out silicone and use sand mastic instead?
Yes. We remove the silicone and clean the joint before the sand mastic goes in.
Is it messy?
We keep the work tidy. We protect what’s around the joints, and we clear up when we are done.
When it isn’t the sealant
A few problems are outside what sealant work can do:
- Broken panes
- Crumbling stone or brickwork round the window
- Whether work needs listed building consent
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly.
Surfaces we seal
- Tenement windows
- Timber door frames
- Brick reveals
- Stone surrounds
- Sash and case windows
- Period & listed homes
Aftercare tips
After the cure time, these simple habits help:
- Take care around the mastic when scraping paint
- Get any rot dealt with first
- Look over the window mastic once a year
- Don’t paint over the new mastic
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
What affects the cost of sand mastic
The quote reflects the job in front of us. We look at:
- Whether old sealant or filler has to be cut out
- The number and length of the joints
- How many areas need sealing
- The product the joint needs
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
