Aftercare tips
Good habits help new joints last longer. A few tips:
- Rest ladders on the wall, not the gutter
- Clear leaves and moss from the gutters
- Sort out a dripping joint early
- Get a dropping gutter looked at quickly
Clear the gutters once or twice a year so water does not sit on the joints. Standing water strains every seal.
Once roofline sealant splits, water can get behind it. Sealing it early keeps the boards behind dry.
Gutter sealing in Coulter, done properly
For gutter sealant to hold, the joint has to be clean and dry. That is why we take out the old sealant and dirt first and the joint is dried before the new sealant goes in. If you are dealing with leaking gutter joints and stop ends and dripping gutter ends, we can put it right, whatever the surface.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Outside joints on exposed walls work hard.
You’re covered for a year from the day we finish. If anything isn’t right with it, email us at info@mrmastic.co.uk.

Gutter sealing in Coulter: local notes
Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Around Coulter, as everywhere, gutter sealing is only as good as the preparation behind it.

Why it’s worth doing now in Coulter
Sealing over a dirty, wet joint is a quick fix that rarely lasts but it tends to peel off. Cleaning out and drying the joint first is what makes it last. 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.
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Advice
Do you need gutter sealing in Coulter?
Overflowing gutters can look like leaking joints. A blocked downpipe makes water back up, which is why we look before we seal.
The most common problems we see are:
- Drips from gutter joints and end caps
- Old sealant on roofline trims that has split
- Internal damp traced to a gutter joint
- Dripping gutter ends
In the older streets around Culter Parish Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
