Carluke Window Mastic
Window and door frames in Carluke need attention? We cut out the old, prepare the joints and apply the right sealant.
- Gaps where the sill meets the wall
- Mastic that’s falling out in pieces
- Whistling draughts around closed windows
Window mastic in Carluke, done properly
The new joint does not have to be white. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. Typical jobs include white mastic on grey or black frames and leaking joints at the ends of sills, across uPVC windows, aluminium frames and patio & French doors.
In a town like Carluke, stone-built older streets normally sit alongside harled houses and newer estates, so windows range from sash and case in older buildings to uPVC on newer homes. Each needs the right sealant against the right wall.
We stand behind the work with a 12-month guarantee, so you are covered after we have gone.

What we’re called out for in Carluke
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
It’s worth asking for a quote if you see:
- Gaps where the sill meets the wall
- Black, perished sealant on frames
- Gaps left after new windows were fitted
- Cold air getting in at the frame edge
Cambusnethan House, about 4.6 miles west, is one of the historic houses in the wider area around Carluke, and older homes nearby need a sealant that suits their walls.

Why act early in Carluke
Resealing frames is a short job: it 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. Private landlords in a town like Carluke must keep homes wind and watertight under the Repairing Standard. Sorting failed joints early is easier than dealing with a tenant’s complaint.
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

What we do, step by step
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. For a job in Carluke, tell us where the work is, how to get in and where to park. Outside work depends on the weather, as sealant needs a dry surface.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any leaks or damp you’ve noticed

What affects the cost of window mastic

- Whether the work is at height
- Any mould that needs treating
- How many rooms, windows or areas are involved

Composite doors
A composite door usually sits in a plastic outer frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. We’ll point out any rot we find, as a joiner will need to deal with it.
Frames and glazing around Carluke
Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Historic houses like Cambusnethan House (about 4.6 miles west) are a reminder that the area around Carluke has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For site and facilities teams at buildings such as Carluke High School, its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Carluke station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Air rooms to keep condensation down around windows
- Repaint timber before it’s bare
- Walk round the house once a year and look at the joints
- Keep drainage slots and sill grooves clear
Try not to touch the new joint while it cures, for as long as we advise. Keep jet washers away from the frames.
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. Early resealing stops it reaching that point.
