About our gutter sealing in Nethermill
Sealant only bonds to a clean, dry joint. That is why we take out the old sealant and dirt first, then dry the joint before sealing. If you are dealing with fascia boards with gaps between them and leaking gutter joints and stop ends, we can put it right, on gutter joints, uPVC fascias and soffit joints alike.
External sealant needs dry surfaces, so outdoor work around Nethermill is planned around the weather. Let us know about access to every wall and roofline.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

Nethermill buildings and the weather
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
For jobs in and around Nethermill, choosing the right material for each joint is as important as a tidy finish.

Roofline trims
Roofline trims rely on sealant at their joints. When it splits, water can get behind.
Soffit joints
Open soffit joints let draughts in. A neat seal closes them.

Leave it or put it right?
Sealant won’t clear a blocked downpipe. We look at what’s really happening and point you to the right trade if needed. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please email us at info@mrmastic.co.uk.

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Look along the fascias for open joints
- Look for streaks or damp on the wall below gutters
- Get a dropping gutter looked at quickly
- Keep downpipes clear
Keep the gutters clear of leaves and moss, so water drains away past the joints. Water left in a gutter tests every joint.
Leaking gutter joints get worse over time. Water keeps hitting the same part of the wall and that can cause damp inside.
