How we handle sand mastic in Dalkeith
Sand mastic does not last for ever and gaps open up round the frame. Renewing it closes the gap and tidies the surround. If you have cracked mastic round a front door frame and open joints round the window box, we can put it right, whatever the surface.
Harled walls are common in Scottish towns like Dalkeith, and sealing a frame against rough harling takes a sealant that grips and moves. A bead that sits on top of the harling rather than in the joint soon lets water in.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
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.
How to look after the new joints
A little care helps the new joints last. Our advice:
- Go gently near the mastic when preparing windows
- Make sure water runs off the sill
- Ask a joiner to look at soft timber first
- Renew mastic before redecorating the windows
Leave the new mastic unpainted, as traditional guidance advises. If you’re redecorating, ask us first.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall so early renewal protects both.
The process
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and tidy away. Most jobs take a few hours for a single window, longer for several. Parking around Dalkeith is rarely difficult, though older streets in the centre can be tight. If you’re in a flat with a shared stair or a door entry system, let us know when you book.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Getting ready for the visit
- Let us know about parking restrictions
- Tell us about any water getting in
- Keep pets and children clear of the area while we work

Dalkeith: your questions answered
Do you work for landlords with property near Eskbank station?
Yes, rental work is part of what we do. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we will send you a clear quote.
What guarantee comes with sand mastic in Dalkeith?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
When will the new mastic be hard?
Not right away. It skins first and hardens fully later, and we will tell you what to expect.
Is consent needed for window work on a listed home?
It’s best to ask your local planning authority first. Like-for-like sand mastic is often the preferred finish, but they decide.
Is it possible to take out silicone and use sand mastic instead?
In most cases. The silicone is cut out and the joint cleaned before the sand mastic goes in.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Whether work needs listed building consent
- Crumbling stone or brickwork round the window
- Sash cords, weights and draught-proofing of the sashes
If you’re not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer.

Do you need sand mastic in Dalkeith?
Water gets into small cracks in the mastic and pushes it out. Windows facing the weather tend to go first.
Most people get in touch after spotting one of these:
- Old sand mastic that has cracked, crumbled or fallen out
- Mastic round period door frames that has failed
- Open joints round the window box
- Mastic worn away on windows facing the weather
Rented homes near Eskbank station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

Frames and glazing around Dalkeith
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, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
If you live in an older home near East Kirk, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Managing a site like Dalkeith High School? Then larger buildings have plenty of frames, and the mastic around each one ages.
