Frames and glazing around Hartwood
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Around Hartwood, as everywhere, window mastic is only as good as the preparation behind it. If you let a flat or house near Hartwood station, renewing tired window mastic between tenants heads off draught and damp complaints.

How we handle window mastic in Hartwood
The new joint does not have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. If you have old mastic that has gone black or come away and rain getting in at the frame or under the sill, we can help, whatever the surface.
Outdoor sealant needs a dry surface, so window work around Hartwood is planned around the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
Every job is covered by a one-year guarantee, wherever you are in North Lanarkshire.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
When something else is needed
It helps to know what we cannot do too:
- Faulty window hardware
- A failed sealed unit that has misted up
- Draughts through the window seals rather than the frame
If you are not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer before booking.

- Aluminium frames

Advice
How we quote for window mastic
The quote reflects the job in front of us. We look at:
- How many areas need sealing
- How easy the joints are to reach
- The number and length of the joints
- Whether there’s mould to deal with
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will go through it with you.
Asking for a quote
Photos help, but a description is a good start. Please mention:
- Pictures of the joints, sent by email
- Where the job is, and your postcode
- The rough size of the job
- Any access issues, like height or stairs
If you are in Hartwood and need window mastic, send an email to info@mrmastic.co.uk. A short description of the job and where it is helps us quote, and we will agree the price before any work begins.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Repaint timber before it’s bare
- Wash the frames with mild soapy water
- Keep paint off silicone joints
- Keep drainage slots and sill grooves clear
Check the drainage slots in the frames are not blocked, so rain drains out rather than building up at the sealant.
Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.

Why it’s worth doing now in Hartwood
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
What it costs depends on the amount of work, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.
