Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Paint up to the joint, not over it
- Avoid blasting the frames with a pressure washer
- Ventilate rooms so frames do not stay wet inside
- Look round the frames every year or so
Check the drainage slots in the frames aren’t blocked, so rain drains out rather than building up at the sealant.
Leaks normally show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
Window mastic for homes and businesses in Catterline
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’re dealing with mastic that’s falling out in pieces and cold air getting in at the frame edge, we can help.
Mastic can only go onto a dry joint, so outside work in Catterline depends on the weather. Tell us about access to all the windows and doors, upstairs included.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

What else we do in Catterline
Surface by surface
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.

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.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Common problems we fix in Catterline
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. A sealant that can’t keep up eventually tears.
If you can see any of these, it’s time to have the joints looked at:
- Gaps left after new windows were fitted
- Cracked internal joints between frame and plaster
- Old mastic that has gone black or come away
- Gaps where the sill meets the wall
Letting a property close to Stonehaven station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

Catterline homes and the weather
Catterline is within about 1 mile of 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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
For an older house near a landmark such as Catterline Church, the joint between an old wall and a newer frame is generally the first place rain gets in.
Catterline is about 16 miles north-east of Montrose, in Aberdeenshire. Every kind of property in Catterline is covered for window mastic. The work is guaranteed for a year. Catterline is one of 161 towns and villages in Aberdeenshire we cover for window mastic. We also work in Aberdeen, about 18 miles from Catterline.

Why it’s worth doing now in Catterline
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. A reseal is a much smaller job. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.

The process
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a handful of frames, longer for a whole house for a typical job. For a place like Catterline, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
Getting ready for the visit
- Tell us if parking is tricky
- Mention any leaks or damp you’ve noticed
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Catterline questions
Does living near the coast affect window mastic in Catterline?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are usually the first to need attention.
Can you help a landlord with a rental near Stonehaven station?
Yes, we work for landlords and letting agents. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
Will resealing my frames help with draughts?
In many cases. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.
Do you have sealant for grey or black windows?
Yes. We can use white, brown, anthracite grey, black or clear.
Are you fully insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
How long will my window job take?
Allow a few hours for a handful of frames, longer for a whole house. Access and how stubborn the old mastic is affect the time most.
