About our sand mastic in New Stevenston
We work across New Stevenston renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand, finished to suit the masonry. If you have modern sealant on a period surround and gaps round a timber door in stone or brick, we can help, on stone surrounds, brick reveals and sash and case windows alike.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
You are covered for a year from the day we finish. If anything is not right with it, send an email to info@mrmastic.co.uk.

FAQs for New Stevenston
Do you cover smaller places like New Stevenston?
Yes, New Stevenston is covered. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Holytown station. Can you help?
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.
Do I need permission for sand mastic on a listed building?
It’s best to ask your local planning authority first. Like-for-like sand mastic is often the preferred finish, but they decide.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses and we are fully insured.
Is it OK to seal over old sealant?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
What does sand mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
For anyone letting property in or around New Stevenston, several properties can be quoted together. Send us the addresses and the work at each.
Leave it or put it right?
An open joint round the frame lets weather in. Water can get to the frame and the masonry, so dealing with it now protects both. In a place like New Stevenston, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, send an email to info@mrmastic.co.uk and we will give you an honest view and a quote.

Advice
What sand mastic looks like in New Stevenston
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Rented homes near Holytown station change hands often, and any sash windows need sound mastic to keep draughts and rain out. Schools such as Taylor High School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Historic houses such as Cambusnethan House, about 4.2 miles south, show how far back building around New Stevenston goes, and older homes nearby need a sealant that suits their walls.

DIY versus a professional 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.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
