Sand mastic in Braeside
We renew sand mastic around sash windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. If you’re dealing with patchy fillers round a sash window and window mastic to renew ahead of painting, we can help, on sash and case windows, tenement windows and stone surrounds alike.
Mastic can only go onto a dry joint, so outside work in Braeside depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
You’re covered for a year from the day we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

What happens on the day
The work is kept neat and contained to the area we’re working on, so you can carry on as normal. The job usually takes a few hours per window, depending on the condition of the joints. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Clear the area around the work
- Let us know if you’ve seen damp or leaks

Landlord and commercial work in Braeside
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Landlords and agents in Braeside can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Ask us before painting near the mastic
- Clear gutters so water doesn’t pour onto the windows
- Ask the planning authority about consent for listed or conservation-area homes
- Plan mastic work ahead of painting
Leave the new mastic alone while it firms up. It forms a skin fairly soon but needs longer to fully harden.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
Why it’s worth doing now in Braeside
Cement-based fillers and modern sealants don’t always suit a period 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 usually more efficient than separate visits. We will give you a clear quote for the lot.
Why book with us
- Experience in homes, commercial sites and hotels
- We’re fully insured
- An ARBOMaster approved applicator
- Any old sealant cut out fully, not covered over

Different surfaces, different methods
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. If your home is listed, ask your local planning authority about consent.
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We can do one window or several.
Questions from Braeside
Do you cover smaller places like Braeside?
Yes. Braeside 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.
Does the coastal weather in Braeside affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do I need permission for sand mastic on a listed building?
Your local planning authority is the one to ask. They decide whether consent is needed for work to your windows.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
I’m a tenant. Can you help?
We are happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Do you guarantee sand mastic work?
You get our 12-month guarantee to all our work.
Braeside homes and the weather
Braeside is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. 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.
Letting a property close to Branchton station? Then any sash windows need sound mastic to keep draughts and rain out. Ardgowan House, about 2.4 miles south-west, is one of the historic houses in the wider area around Braeside. Schools such as Inverclyde Academy are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

What sealant work can’t fix
New sealant can’t fix everything, and we’ll tell you before work begins. Sealant will not put right:
- Decayed frames that need repair
- Masonry that needs repairing
- Sash cords, weights and draught-proofing of the sashes
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think before you book.

What affects the cost of sand mastic
We don’t publish a price list, because jobs vary so much. What we look at:
- The number and length of the joints
- The number of rooms or windows
- Any mould that needs treating
- Working hours on commercial sites
The cost depends on the amount of work, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
Asking for a quote
There’s no need for technical detail. Just tell us:
- Photos by email, if that is easy
