About our window mastic in Stoneykirk
There are two joints on most windows. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. If you have gaps where the sill meets the wall and draughty joints inside around the window, we can put it right.
Mastic can only go onto a dry joint, so outside work in Stoneykirk depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
The work is covered for a year after we finish. If anything is not right with it, email us at info@mrmastic.co.uk.

- Condensation trapped between the panes

Do you need window mastic in Stoneykirk?
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
Look out for these signs:
- Cold air getting in at the frame edge
- Mastic that has split away from the wall
- Rain getting in at the frame or under the sill
- White mastic on grey or black frames
In and around Stoneykirk, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
Before booking anyone
- What insurance they hold
- What product goes in the joint
- Is VAT in the price?
- Whether they seal over old material or remove it
Why deal with it now?
The work is quick compared with the damage it prevents: the visit takes a few hours for a handful of frames, longer for a whole house. Wait for damp to appear and there may be plaster and decorating to sort out too. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and give you a clear quote before any work starts.

How the visit works
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a handful of frames, longer for a whole house. Outside jobs in Stoneykirk need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- Mention any tricky access
- Tell us if parking is tricky
- Try not to wet indoor joints just before the visit

Related advice
What window mastic looks like in Stoneykirk
Stoneykirk is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
If you live in an older home near Stoneykirk Old Parish Church and Railing, the joint between an old wall and a newer frame is usually the first place rain gets in.

Questions from Stoneykirk
Is window mastic in a coastal place like Stoneykirk any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you cover Stoneykirk for window mastic?
Yes. We work across all of Scotland, and Stoneykirk is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll send you a clear quote.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Can you seal the gap between the frame and the plaster indoors?
Yes. Plenty of draughts come through the inside joint as well as the outside, so it can be worth sealing both.
Can tenants book the work?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Are you fully insured?
Yes. Mr Mastic is fully insured.
Can you get sealant to suit coloured frames?
Yes. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all.
How to look after the new joints
So the new joints stay in good condition:
- Look round the frames every year or so
- Keep paint and stain on wooden frames in good order
- Wipe condensation off the frames
- Keep solvents and bleach off the sealant
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
What the job involves on each surface
Window sills
Where a sill meets brick or render, the ends often crack first. We reseal them so rain can’t run into the wall.
Composite doors
A composite door generally sits in a plastic outer frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
