What happens if it’s left?

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 has failed, we will tell you. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

How we handle gutter sealing in Newtown St Boswells

A drip at a gutter joint is easy to ignore, but the water lands on the same spot every time it rains. Resealing it is a small job if the gutter is otherwise in good order. We work on gutter end caps, uPVC fascias and roofline trims, and the jobs we see most are streaks down the brickwork from a leaking joint and drips from gutter joints and end caps.

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.

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

Honest limits

In fairness, some problems need a different trade:

  • Problems with the roof covering
  • Water backing up from a blocked pipe
  • Sagging gutters or broken brackets

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

Joints and surfaces we work on

  • Gutter end caps
  • Roofline trims
  • Soffit joints
  • uPVC fascias
  • Gutter joints
  • Garage door frames

Aftercare tips

Simple care keeps the joints in good condition. We recommend:

  • Look along the fascias for open joints
  • Have sagging gutters refixed early
  • Check the gutters during heavy rain
  • Check that water runs out of the downpipes

Have a look at the gutter during a downpour. It’s the easiest time to see a leak.

A leaking garage frame lets water reach stored items. A reseal sorts it.

What affects the cost of gutter sealing

The price is agreed before any work begins. It’s based on:

  • When we can work, for business premises
  • How much there is to do
  • How easy the joints are to reach
  • Whether there’s mould to deal with

Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

What we need to know

When you contact us, it’s useful to know:

  • What the problem is, such as mould, gaps, leaks or cracking
  • Whether it has been sealed before
  • Whether it’s a home or a business
  • How many joints, rooms or windows are involved

Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. When it suits you, email us at info@mrmastic.co.uk.

Common problems we fix in Newtown St Boswells

End caps get knocked or pushed by water. If the seal fails, water escapes at the end and runs down the wall.

Look out for any of the following:

  • End caps that drip every time it rains
  • Quick sealant fixes on gutters that didn’t last
  • Wet patches on the wall under a gutter joint
  • Rain getting in around a garage door

If you let a flat or house near Tweedbank station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

What your quote should include

  • How long the guarantee is
  • How much experience the applicator has
  • How long to leave it before use
  • How the colour is chosen

Our hiring checklist

Walls and rooflines in Newtown St Boswells

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. Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.

For site and facilities teams at buildings such as Newtown Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
