Gutter sealing for Walston homes and businesses

How we handle gutter sealing in Walston

Our work covers gutter joints and end caps as well as fascias and soffits plus roofline trims and garage door frames. It’s all about the joints, not replacing the gutter. If you have end caps that drip every time it rains and trim joints where the sealant has failed, we can put it right, whatever the surface.

Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. On newer homes, the movement joints and roofline trims are what need watching.

There’s a 12-month guarantee on every job.

What sealant work can’t fix

Honest advice matters more to us than a booking, so here’s what sealant can’t fix:

  • Leaks from the roof rather than a joint
  • Fascias that need replacing
  • Guttering that needs replacing

Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly.

What happens if it’s left?

If the problem is a blocked downpipe, sealing won’t help. We look at what’s really happening and tell you if something else is needed. In an older home around Walston, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Can I do it myself?

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Walston buildings and the weather

Harled (roughcast) walls are common in Scotland, 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 sound outside sealant is part of that.

In the older streets around Walston Parish Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. In and around Walston, as anywhere, good gutter sealing starts with a clean, dry, properly prepared joint.

For gutter sealing in Walston, drop us a line at info@mrmastic.co.uk. Tell us what the problem is and where, and you’ll get a clear quote before any work starts.

What we do, step by step

Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from an hour or two to a few hours. Outside jobs in Walston need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.

  1. First we trace the drip and check the gutter is not damaged.
  2. The old sealant and dirt are cleaned out of the joint.
  3. We dry the joint so the new sealant can bond.
  4. We seal the joint with a sealant made for gutters.
  5. The gutter is checked and debris around the joints cleared.

Getting ready for the visit

  • Tell us if parking is tricky
  • Clear items away from the joints we’re working on
  • Let us know if you’ve seen damp or leaks
