Frames and glazing around Cousland
With historic houses such as Hamilton House (about 3.6 miles north) nearby, there’s older building stock in the area around Cousland as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Hamilton House, about 3.6 miles north, is one of the historic houses in the wider area around Cousland, and older homes nearby need a sealant that suits their walls.

Window mastic for homes and businesses in Cousland
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through. If the draught is through the window seals instead, we will tell you. If you’re dealing with untidy mastic left by window fitters and cracked internal joints between frame and plaster, we can put it right.
Outdoor sealant needs a dry surface, so window work around Cousland is planned around the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
The work is covered for a year after we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

Honest limits
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Damp coming through the wall itself rather than the frame joint
- Faulty window hardware
- Draughts through the window seals rather than the frame
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly.

What we are called out for in Cousland
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
Common reasons people contact us are:
- Cold air getting in at the frame edge
- Cracked or shrunken mastic around the frame
- Old mastic that has gone black or come away
- Rain getting in at the frame or under the sill
Rented homes near Wallyford station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
What your quote should include
- Whether the sealant suits the joint
- Are they insured?
- What happens if they find a problem under the old sealant
- Whether all the old sealant comes out first
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Clean frames with a soft cloth and soapy water
- Make sure the drainage slots are not blocked
- Wipe condensation off the frames
- Keep paint off silicone joints
Try not to touch the new joint while it cures, for as long as we advise. Do not point a pressure washer at the joints.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.

Yes, Cousland is within the area we cover. Our work covers the whole of Scotland. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
Do you cover smaller places like Cousland?
Yes. Cousland is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Is it OK to seal over old sealant?

Yes, where they can be reached safely. Tell us about access when you get in touch and we’ll plan for it.
Are you insured?
Yes. Full insurance covers our work.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we are using.

Advice
Work for landlords, hotels and businesses
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
What the job involves on each surface
Window sills
Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. They’re cut out and resealed with exterior sealant.
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.
