Window mastic in Gardenhall
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. If you have white mastic on grey or black frames and gaps where the sill meets the wall, we can help, whatever the surface.
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.
A one-year guarantee comes with the work, just as it does everywhere we cover.

For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll give you a quote.
Why deal with it now?
If you are painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished. In an older home around Gardenhall, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What you get with us
- Arbo and Everbuild products
- Sanitary silicone with an anti-fungal additive in wet areas
- Fully insured
- More than 20 years in sealant work

Quotes for window mastic in Gardenhall
We don’t publish a price list, because no two jobs are the same. The quote depends on:
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
- How many rooms, windows or areas are involved
- Working hours on commercial sites
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
Helping us quote
Photos by email are helpful but not essential. Please mention:
- If someone has resealed it before
- What’s wrong with the joints now
- Pictures of the joints, sent by email
- Where the job is, and your postcode
We do not publish a price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To get started, email us at info@mrmastic.co.uk.
Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Frames and glazing around Gardenhall
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Gardenhall is in the west of Scotland, which is wetter than the east, which means the mastic around window and door frames has to cope with a lot of rain.
Schools such as Duncanrig Secondary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Hairmyres station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

How it works
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take a few hours for a few frames, or a day or more for a whole house. Around Gardenhall, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- Try not to wet indoor joints just before the visit
- Let us know about parking restrictions
- Plan for the work area to be out of bounds to pets and children

Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.

Are you ARBOMaster approved?

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Repaint timber before it’s bare
- Keep solvents and bleach off the sealant
- Check the mastic once a year
- Avoid blasting the frames with a pressure washer
Check the drainage slots in the frames aren’t blocked, so rain drains out rather than building up at the sealant.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
