About our sand mastic in Newbridge
Sand mastic does not last for ever and gaps open up round the frame. We rake it out and renew it so the surround looks right again. If you have gaps where the frame meets the masonry and silicone on a period window that looks wrong, we can help, whatever the surface.
Mastic can only go onto a dry joint, so outside work in Newbridge depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
You are covered for a year from the day we finish. If anything is not right with it, drop us a line at info@mrmastic.co.uk.

Newbridge 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. 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.
If you look after a building such as Maxwelltown High School, larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Dumfries station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for a single window, longer for several. Around Newbridge, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Tell us about access, such as stairs, a lift or high-level joints
- For business premises, tell us about site rules or sign-in

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Renew mastic before redecorating the windows
- Avoid patching sand mastic with silicone
- Go gently near the mastic when preparing windows
- Ask a joiner to look at soft timber first
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.
For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Housing providers, facilities teams and property managers book us too in Newbridge and across Dumfries and Galloway. We can quote a run of properties together, and we are fully insured for the work.
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Do you need sand mastic in Newbridge?
Water gets into small cracks in the mastic and pushes it out. Windows facing the weather tend to go first.
The most common problems we see are:
- Failed mastic on an exposed elevation
- Mastic dropping out of the joint
- A silicone bead on a sash window that spoils the look
- Draughts and rain around sash boxes
In the older streets around Holywood Parish Church And Churchyard, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Newbridge questions
Do you work for landlords with property near Dumfries station?
Yes, rental work is part of what we do. Just email us at info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
Do you cover smaller places like Newbridge?
Yes. Newbridge is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Can I paint the new mastic?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
When will the new mastic be hard?
It takes a while. It skins first and hardens fully later and we will give you an idea for your job.
Is consent needed for window work on a listed home?
Your local planning authority is the one to ask. They’ll tell you if consent is needed for work to your windows.
Do you work for hotels and businesses?
Yes, regularly. We can plan bigger jobs in stages.
What we cannot put right
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Decisions on consent for listed homes
- Sash cords, weights and draught-proofing of the sashes
- Decayed frames that need repair
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly before you book.
What we seal
- Brick reveals
- Period & listed homes
- Sash and case windows
- Timber door frames
- Tenement windows
- Stone surrounds
Why it’s worth doing now in Newbridge
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry, so dealing with it now protects both. 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.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and send you a clear quote before we start.
