Questions from Kilsyth
Do you work for landlords with property near Croy station?
Yes, rental work is part of what we do. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before any work starts.
Will you come out to Kilsyth?
Yes, we do. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Is consent needed for window work on a listed home?
Yes, it’s worth checking. Your local planning authority can say if consent is needed for work on a listed home or in a conservation area.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we are using and why.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Can old silicone round a sash window be swapped for sand mastic?
Yes, we do this often. The old silicone has to come out completely so the mastic can sit properly.
Do you guarantee sand mastic work?
There’s a 12-month guarantee on every job, sand mastic included.
Sand mastic in Kilsyth
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. We are often asked to deal with wind and rain getting in round a sash window and patchy fillers round a sash window, on timber door frames, brick reveals and tenement windows.
In and around a place like Kilsyth, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
There’s a 12-month guarantee on every job, large or small.

Sand mastic in Kilsyth: local notes
Kilsyth is in the west of Scotland, which is wetter than the east, which means the mastic around older windows and doors has to cope with a lot of rain. 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.
For landlords with property near Croy station, older sash windows in a rental need their mastic kept sound to keep the weather out.
Kilsyth is about 3 miles north-west of Cumbernauld, in North Lanarkshire. Whether you are in the middle of Kilsyth or further out, sand mastic is available for homes and businesses alike. Our North Lanarkshire coverage runs to 89 places, Kilsyth among them. Our Glasgow page covers work nearby (12 miles or so).
All of G65 is covered for sand mastic, from the main roads to the quietest streets. Local streets include Main Street, Market Street and Station Road. Kilsyth sits on or near the A803 and B802, so getting to you is simple. Neighbouring places we cover for sand mastic include Auchinstarry (1 mile south), Croy (1 mile south-east), Queenzieburn (1 mile west), Craigmarloch (2 miles south-east) and Dullatur (2 miles east). We also work in nearby towns such as Motherwell (13 miles south), Cumbernauld (3 miles south-east), Coatbridge (9 miles south), Airdrie (8 miles south), Wishaw (15 miles south) and Bellshill (11 miles south).

What’s near Kilsyth
For rail, the closest station is Croy station, about 1.7 miles south-east of the centre. Well-known places in the area include Antonine Centre (3.3 miles south-east) and Kilsyth Victoria Cottage Hospital (0.5 miles west). The countryside around Kilsyth includes Antermony Loch and Bar Hill.
DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Timber that has rotted
- Damaged stone surrounds
- Putty and glazing repairs
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before booking.
What we seal
- Sash and case windows
- Brick reveals
- Tenement windows

How we quote for sand mastic
Every job gets its own quote. These are the things that affect it:
- How many rooms, windows or areas are involved
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
- Access and height
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Asking for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Roughly how big the job is

- Where the job is, and your postcode
- Any previous sealing or DIY work

What we do, step by step
We keep the work tidy and contained to the area we are working on. The job usually takes a few hours per window, depending on the condition of the joints, and we tell you how long to leave it before we go. Somewhere like Kilsyth may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We look at the surrounds with you and agree the joints to renew.
- 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.
- The surface is finished to suit the stone or brick.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints
- Where the joints are inside, avoid wetting them before we arrive

What happens if it’s left?
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new work lasts. In a place like Kilsyth, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please drop us a line at info@mrmastic.co.uk and we will talk you through it.

When to call us in Kilsyth
Rain on the window surround works into any crack and pushes it out. Windows facing the weather tend to go first.
If you can see any of these, it’s time to have the joints looked at:
- Gaps where the frame meets the masonry
- Modern sealant on a period surround
- Patchy fillers round a sash window
- Crumbling sand mastic round a window
Homes close to Kilsyth Parish Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What your quote should include
- When the joint can take water or movement
- How the joint is cleaned and prepared
- The length of the guarantee
