Gutter Sealing in Dewartown
Our applicators work in Dewartown on sealing leaking gutter joints, end caps, fascias, soffits and roofline trims. Old sealant removed completely, joints prepared properly.
- Damp on an inside wall under a dripping gutter
- Fascia boards with gaps between them
- Old gutter sealant that has let go
Gutter sealing in Dewartown
Open fascia and soffit joints spoil the roofline and can let weather in. We seal them in a colour to suit where one is available. If you have rain getting in around a garage door and internal damp traced to a gutter joint, we can help, on soffit joints, uPVC fascias and gutter joints alike.
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.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

What affects the cost of gutter sealing
Call for a quick quote. What matters most is:
- The old material and how stubborn it is
- The number of rooms or windows
- Which sealant suits the joint
- The amount of work
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Helping us quote
To make quoting easier, please include:
- Any access issues, like height or stairs
- If someone has resealed it before
- Roughly how big the job is
- The type of property
Every job is quoted individually, so start by telling us what you need. Simply email us at info@mrmastic.co.uk and describe the job.
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Look for streaks or damp on the wall below gutters
- Check fascia and soffit joints for gaps
- Don’t lean ladders against the gutter itself
- Keep the gutters clear of debris
Have a look at the gutter during a downpour. It’s the easiest time to see a leak.
Early sealing limits how much water hits the wall. If we find a bigger problem, we’ll tell you.
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Do you replace gutters or fascias?
We do not replace gutters or fascias. We will tell you if the gutter needs replacing so you can call the right trade.
Can you seal fascia and soffit joints?
Yes, it’s a common job. The gaps are cleaned and sealed neatly.
Can sealant stop a sagging gutter leaking?
Sealant won’t hold a sagging gutter. The gutter needs refixing by a gutter installer.
Can you seal over the old sealant?
No, it won’t last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.

Why it’s worth doing now in Dewartown
New gutters cost far more than a few resealed joints. If the gutter is sound and the drip is a joint a reseal is all it needs. If it’s broken or sagging, a gutter installer needs to look. In a place like Dewartown, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts.

Gutter sealing in Dewartown: local notes
