About our window mastic in Priestland
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. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. Typical jobs include cracked sealant at the sill ends and gaps left after new windows were fitted, across timber windows & doors, uPVC windows and composite doors.
Outdoor sealant needs a dry surface, so window work around Priestland is planned around the weather. Tell us about access to all the windows and doors, upstairs included.
Each job carries a 12-month guarantee.

Landlord and commercial work in Priestland
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured for the work.
Can I do it myself?
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, and the work is guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Wash the frames with mild soapy water
- Keep drainage slots and sill grooves clear
- Walk round the house once a year and look at the joints
- Do not paint over the silicone
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.

Do you need window mastic in Priestland?
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, while a joint packed solid can’t stretch. Backing rod sets the right depth.
The problems people generally mention when they call include:
- Water coming in at the bottom corners of a door
- Whistling draughts around closed windows
- Old mastic that has gone black or come away
- Untidy mastic left by window fitters
For an older house near a landmark such as Darvel Central Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Before you book anyone
- Whether they seal over old material or remove it
- Which sealant they’ll use, and why
- Is VAT in the price?
- What happens if they find a problem under the old sealant
How the visit works
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes a few hours for a handful of frames, longer for a whole house from start to finish. Somewhere like Priestland may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- 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.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Clear items away from the joints we are working on
- Keep children and pets away from the work area
- Mention any tricky access

Window mastic in Priestland: local notes
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
