About our gutter sealing in Thornhill
Gutter and fascia replacement is not our trade, and nor is roofing. What sealant does is close joints and it can’t mend broken brackets, split sections or blocked downpipes. We work on gutter joints, uPVC fascias and soffit joints, and people most often call us about old gutter sealant that has let go and damp on an inside wall under a dripping gutter.
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, so they need a sealant that moves with the building.
A one-year guarantee comes as standard, so you are covered after we have gone.

Different surfaces, different methods
Gutter end caps
Stop ends hold back water at the end of a run. When their seal fails, they drip.
uPVC fascias
Joints between fascia boards can open over time. They’re sealed tidily in a suitable colour.
How to look after the new joints
After the cure time, these simple habits help:
- Clear leaves and moss from the gutters
- Keep an eye out for wet patches below a joint
- Keep ladders off the guttering
- Glance at the soffit joints now and then
Give the sealant the cure time we tell you before poking or cleaning near it.
A drip from a gutter joint will not stop on its own. The same spot gets soaked every time it rains and that can cause damp inside.
DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
When something else is needed
To be straight with you, there are a few things sealant will not fix:
- Gutters that have dropped or pulled away
- Guttering that needs replacing
- Leaks from the roof rather than a joint
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.
Joints and surfaces we work on

What happens on the day
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take an hour or two for a few joints, longer for a full run. Somewhere like Thornhill may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- First, we find the drip and check the gutter is not cracked or sagging.
- We clean out the joint and take out the old sealant.
- The joint is dried, because sealant won’t bond to a wet surface.
- Gutter or exterior sealant is applied and finished.
- We look along the gutter and clear debris around the joints.
How to prepare
- Mention if the joints have been sealed before
- Mention any parking rules near the property
- Mention any tricky access
