How we handle sand mastic in Dumbreck
Across Dumbreck, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand, finished to suit the masonry. We’re often asked to deal with cracked mastic round a front door frame and weathered mastic on the most exposed windows, on brick reveals, timber door frames and stone surrounds.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, and plenty still have them. In Dumbreck, as anywhere, the mastic between frame and wall is what stops draughts and rain getting in.
Every job is covered by a one-year guarantee, wherever you are in Glasgow.

A traditional finish suits a period property.
Frames and glazing around Dumbreck
Historic houses like Pollok House (about 1.2 miles south) are a reminder that the area around Dumbreck has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Glasgow’s tenements are largely red and blond sandstone, and porous sandstone needs a sealant that will not mark it.
Letting a property close to Dumbreck station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. Homes close to Sherbrooke St Gilbert's Church include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.

How the visit works
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes a few hours per window, depending on the condition of the joints, including the tidy-up. For a tenement in Dumbreck, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. Tell us which applies when you book.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Mention if the joints have been sealed before
- Tell us if parking is tricky

Why deal with it now?
An open joint round the frame lets weather in. Water can get to the frame and the masonry so renewing it early protects the window. For landlords in Dumbreck, damp and leaks can be a Repairing Standard issue, so it’s worth fixing failed sealant before a tenant reports it.
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.
What you get with us
- More than 20 years in sealant work
- Anti-fungal sanitary silicone in wet areas
- An ARBOMaster approved applicator
- Tidy, careful work
Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Questions from Dumbreck
How do repairs to the shared parts of a tenement in Dumbreck get organised?
It generally goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 covers the common parts where the deeds do not, and we can quote for the factor or the owners directly.
Can you do sand mastic in Dumbreck?
Yes, Dumbreck is within the area we cover. We work across all of Scotland. You can email us at info@mrmastic.co.uk and tell us what needs doing.
How long does sand mastic take to go off?
The surface skins quite quickly and it hardens fully over a longer time. Timing depends on the weather and the joint.
Do you have insurance?
Yes. We are fully insured for domestic and commercial work.
What information do you need?
A short description and the location, plus photos if you have them. We will ask anything else we need to know.
Can old silicone round a sash window be swapped for sand mastic?
Often, yes. With the silicone removed and the joint cleaned we point it with sand mastic.
Can you quote for more than one area?
Yes. Just list everything you need and we will quote it together.
Will the old sealant be removed?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Common problems we fix in Dumbreck
Paint, silicone or cement used over old mastic causes problems. They don’t move with the timber, and they generally need raking out.
It’s worth asking for a quote if you see:
- Silicone on a period window that looks wrong
- Failed mastic on an exposed elevation
- Open joints round the window box
- Old cement repairs round a window that have failed
Managing a site like Bellahouston Academy? Then its window and door frames need their mastic kept sound, just like a home’s.
