About our sand mastic in Quarter
Silicone on a period window often looks wrong and doesn’t suit the building. Sand mastic is the traditional choice, and we can replace one with the other. We work on period & listed homes, sash and case windows and stone surrounds, and people most often call us about cracked mastic round a front door frame and weathered mastic on the most exposed windows.
Outdoor sealant needs a dry surface, so window work around Quarter is planned around the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
Every job comes with a one-year guarantee.

What sand mastic looks like in Quarter
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. The west of Scotland is wetter than the east, which means the mastic around older windows and doors has to cope with a lot of rain.
For site and facilities teams at buildings such as Larkhall Academy, the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near Quarter Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Quarter is about 2 miles west of Larkhall, in South Lanarkshire. Wherever you are in the ML3 postcode area, we can carry out sand mastic at your property. Across South Lanarkshire, we cover 139 places, and Quarter is one of them. Glasgow is on our list too, about 12 miles from Quarter.

What the job involves on each surface
Period and listed homes
A traditional finish suits a period property, and sand mastic is one of them.
Stone surrounds
The stone is treated with care when the old mastic comes out.
How to look after the new joints
After the cure time, these simple habits help:
- Check with your local planning authority if your home is listed
- Plan mastic work ahead of painting
- Keep sills and gutters clear so water drains away
- Go gently near the mastic when preparing windows
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
Your questions about sand mastic in Quarter
Do you cover Quarter for sand mastic?
Yes. Our work covers the whole of Scotland, and Quarter is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we’ll send you a clear quote.
Can you help a landlord with a rental near Chatelherault station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear quote.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. Then send an email to info@mrmastic.co.uk.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Why deal with it now?
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic is the traditional material and finishes neatly against the masonry. In an older home around Quarter, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.
Why choose Mr Mastic in Quarter
- Homes, businesses and hotels
- Every job guaranteed for a year
- Approved under the ARBOMaster scheme

The process
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes anything from a few hours to a full day, depending on how many windows. Outside jobs in Quarter need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Mention any parking rules near the property
- Plan for the work area to be out of bounds to pets and children

Do you need sand mastic in Quarter?
Age is the main cause. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
Look out for any of the following:
- Draughty sash windows at the surround
- Silicone on a period window that looks wrong
- Mastic worn away on windows facing the weather
- Mastic dropping out of the joint
For landlords with property near Chatelherault station, any sash windows need sound mastic to keep draughts and rain out.
