How we handle sand mastic in Rosewell
A silicone bead around a sash window can look out of place and doesn’t suit the building. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. We work on timber door frames, tenement windows and sash and case windows, and common reasons people get in touch are tired mastic found when preparing windows for paint and cement or filler used on old window joints that has cracked.
Outdoor sealant needs a dry surface, so window work around Rosewell is planned around the weather. Tell us about access to all the windows and doors, upstairs included.
Big or small, you get the same one-year guarantee in Rosewell and across Midlothian.

Why it’s worth doing now in Rosewell
Not every filler suits an old window surround. Sand mastic matches what was there and that can be important for listed homes. 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.
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear price for the lot.

How the visit works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It generally takes a few hours per window, depending on the condition of the joints. Outside jobs in Rosewell 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 isn’t affected.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Tell us about access, such as stairs, a lift or high-level joints
- Try not to wet indoor joints just before the visit

Advice
Looking after it afterwards
So the new joints stay in good condition:
- Check with your local planning authority if your home is listed
- Take care around the mastic when scraping paint
- Inspect the joints round the windows every year or so
- Don’t run silicone over sand mastic
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.
When something else is needed
We won’t take on work that will not last, so here’s what sealant cannot put right:
- Whether work needs listed building consent
- Sashes that need overhauling
- Decayed frames that need repair

Rosewell questions
Is Rosewell in your area for sand mastic?
Yes. Our work covers the whole of Scotland, and Rosewell is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
Will you come out to Rosewell?
Yes, Rosewell is covered. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Is consent needed for window work on a listed 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.
Do you offer different sealant colours?
We help you choose a colour that suits. The product needed can limit the range.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Can new sealant go over the old?
No. The old sealant always comes out first, so the new sealant bonds properly.
Can you quote for more than one area?
Of course. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Do you have insurance?
Yes. We’re fully insured for every job we do.
What the job involves on each surface
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.
Tenement and terrace windows
Where a building is shared, window work may involve neighbours so it’s worth checking responsibilities.
When to call us in Rosewell
Timber frames move with the seasons. That movement opens up the mastic joint over time.
The problems people generally mention when they call are:
- Old cement repairs round a window that have failed
- Crumbling sand mastic round a window
- Cracked mastic round a front door frame
- Modern sealant on a period surround
For site and facilities teams at buildings such as Lasswade High School Centre, its window and door frames need their mastic kept sound, just like a home’s.

What sand mastic looks like in Rosewell
Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Historic houses like Melville Castle (about 3 miles north-east) are a reminder that the area around Rosewell has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you let a flat or house near Newtongrange station, cracked sand mastic around sash windows lets in the draughts tenants complain about. For an older house near a landmark such as Rosewell Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
