What we do, step by step

Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours, depending on the number of joints and the access. Somewhere like Leswalt may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.

  1. First we trace the drip and check the gutter isn’t damaged.
  2. We remove the old sealant and clean the joint.
  3. The joint is dried before sealing.
  4. We seal the joint with a sealant made for gutters.
  5. We check the run and clear debris near the joints.

Advice

Gutter sealing in Leswalt, done properly

It’s easy to live with a dripping gutter joint, but each shower sends water to the same place. Resealing it is a small job while the gutter is still sound. Typical jobs include damp on an inside wall under a dripping gutter and end caps that drip every time it rains, across gutter end caps, roofline trims and garage door frames.

Outside joints can only be sealed when they’re dry, so work in Leswalt depends on the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.

Each job carries a 12-month guarantee, large or small.

Quotes for gutter sealing in Leswalt

Some jobs are bigger than they look, and some smaller. The main factors:

  • How much old sealant there is and how hard it is to remove
  • How many rooms, windows or areas are involved
  • The number and length of the joints
  • Which sealant suits the joint

Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, email us at info@mrmastic.co.uk and we will give you an honest view and a quote.

What to tell us for a quote

Before you ask for a quote, have a think about:

  • A few pictures by email, if you can
  • If someone has resealed it before
  • The type of property
  • How many joints, rooms or windows are involved

Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we will explain what’s involved before giving you a price.

Why act early in Leswalt

A dripping stop end can soak the wall right through the wet months. It’s a small job to put right before the damage spreads. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.

The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and agree the price before starting.

Why book with us

  • We leave the area clean and tidy
  • Sealant colour chosen to suit
  • Over 20 years’ experience
  • Trusted Arbo and Everbuild sealants

Walls and rooflines in Leswalt

Leswalt is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on gutter, fascia and roofline joints, which can dry out and crack sooner where a building faces the weather. Leswalt is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for gutter, fascia and roofline joints to keep out.

For an older house near a landmark such as Leswalt Parish Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Signs you need gutter sealing in Leswalt

Gutter joints depend on seals that wear out. Sun and cold make the gutter expand and contract, and old seals crack or slip.

Any of these means the joints need attention:

  • Cracked sealant along roofline trims
  • Damp on an inside wall under a dripping gutter
  • Wet patches on the wall under a gutter joint
  • Rain getting in around a garage door

Rented homes near Stranraer station change hands often, and a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

Soffit joints

Soffit joints are sealed in a colour to suit.

uPVC fascias

Gaps in fascias spoil the roofline. A neat bead closes them up.

DIY versus a professional finish

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

What sealant work can’t fix

We’d rather tell you now than do work that won’t last, so these are the limits:

  • Roof leaks, slipped tiles or failed flashing (a roofer’s job)
  • Sagging gutters or broken brackets
  • Rotten or damaged fascia boards

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