Window & door mastic in Dundonald, East Ayrshire
Mastic around window and door frames, sills and patio doors for householders, landlords and businesses in Dundonald. Fully insured, ARBOMaster approved and guaranteed for a year.
- Draughts coming in around windows and doors
- Rain getting in at the frame or under the sill
- Gaps left after new windows were fitted
Window mastic for homes and businesses in Dundonald
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. We are often asked to deal with mastic that has split away from the wall and cracked sealant at the sill ends, on timber windows & doors, aluminium frames and uPVC windows.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
Every job is covered by a 12-month guarantee.

Why it’s worth doing now in Dundonald
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. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we will explain what it covers.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Signs you need window mastic in Dundonald
On timber frames, paint and putty build up around the joint. 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:
- White mastic on grey or black frames
- Cold air getting in at the frame edge
- Mastic that has split away from the wall
- Untidy mastic left by window fitters
For an older house near a landmark such as Dundonald Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Questions to ask before booking
- Whether they’re fully insured
- Whether you can choose the colour
- Whether the sealant suits the joint
- Is the old sealant removed completely?
When something else is needed
We’ll always be straight with you, so here’s what sealant cannot fix:
- Soft or decayed wood in the frame
- Damp problems in the wall away from the window
- Faulty window hardware

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.

- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Clear the area around the work
- Mention any leaks or damp you’ve noticed
- Tell us about access, such as stairs, a lift or high-level joints

What window mastic looks like in Dundonald
Dundonald is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around window and door frames, especially on the side facing the sea. The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around window and door frames to keep out.
Rented homes near Barassie station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
