For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Sand mastic in Cathkin, done properly
Across Cathkin, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. We work on timber door frames, brick reveals and period & listed homes, and common reasons people get in touch are tired mastic found when preparing windows for paint and old cement repairs round a window that have failed.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Big or small, it’s backed by our one-year guarantee.

What affects the cost of sand mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How easy the joints are to reach
- Whether old sealant or filler has to be cut out
- The number of rooms or windows
- The amount of work
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
Asking for a quote
Photos help, but a description is a good start. Please mention:

- Any access issues, like height or stairs
- Where the property is

Windows and doors in Cathkin
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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Letting a property close to Burnside station? Then older sash windows in a rental need their mastic kept sound to keep the weather out. Managing a site like Fernhill School? Then larger buildings have plenty of frames, and the mastic around each one ages.

How it works
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. It usually takes anything from a few hours to a full day, depending on how many windows. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Mention any tricky access
- Mention any sign-in or site rules at work premises

What happens if it’s left?
Filling over old, loose mastic doesn’t last. We remove the loose material first so the new mastic stays put. Around Cathkin, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, send an email to info@mrmastic.co.uk and we’ll give you an honest view and a quote.

DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
When to call us in Cathkin
Paint, silicone or cement used over old mastic causes problems. They do not suit the joint and we normally remove them.
Any of these means the joints need attention:
- Modern sealant on a period surround
- Old sand mastic that has cracked, crumbled or fallen out
- Gaps round a timber door in stone or brick
- Patchy fillers round a sash window
Provand's Lordship, about 4.4 miles north-west, is one of the historic houses in the wider area around Cathkin, and older homes nearby need a sealant that suits their walls.

Common questions in Cathkin
Is Cathkin within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Burnside station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
Is sand mastic better than silicone for my windows?
We will help you decide. Sand mastic suits many period homes, and modern sealants suit newer frames.
Are you fully insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
What do you need from me for a quote?
Let us know what needs doing and where. If we need more, we will ask.
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.
Should I check with the council before work on a listed or conservation-area home?
Yes, it’s worth checking. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
