Gutter sealing near Thurso

Gutter sealing in Thurso, done properly

A leaking gutter joint marks the wall and wets the ground underneath. Resealing the joint is often all it needs, as long as the gutter is sound. Typical jobs include fascia boards with gaps between them and internal damp traced to a gutter joint, on gutter end caps, garage door frames and soffit joints.

In a Scottish town like Thurso, wind-driven rain finds any gap on the outside of a building. Gaps in gutter joints, fascias and wall joints are where damp starts.

The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

Should I try it myself first?

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

If you’ve already had a go yourself, that’s fine. We cut it out and start again.

Outside joints around Thurso

Thurso is close to 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.

Rented homes near Thurso station change hands often, and leaking gutter joints on a rental are best caught before they stain the walls. If you look after a building such as Thurso High School, larger buildings have long runs of movement joint that eventually need resealing.

What we do, step by step

A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. It normally takes anything from an hour or two to a few hours. In a Scottish town like Thurso, parking is usually straightforward, though older centres can be tighter. If you’re in a flat with a shared stair or a door entry system, let us know when you book.

  1. We find where the water is coming from and check the gutter is sound.
  2. The old sealant and dirt are cleaned out of the joint.
  3. The joint is dried before sealing.
  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

  • Where the joints are inside, avoid wetting them before we arrive
  • Keep children and pets away from the work area
  • Mention any leaks or damp you’ve noticed

What affects the quote in Thurso

Jobs vary more than people expect. What affects the quote:

  • Whether old sealant or filler has to be cut out
  • Mould in or behind the old joints
  • How many areas need sealing
  • The number and length of the joints

Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

Asking for a quote

There’s no need for technical detail. It helps if you can tell us:

  • If someone has resealed it before
  • Any access issues, like height or stairs
  • Roughly how big the job is
  • Photos by email, if that’s easy

Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand, and we will come back to you with a quote.

Surface by surface

Roofline trims

Questions from Thurso

I let a flat near Thurso station. Can you help?

Yes. We work for landlords and agents as well as householders. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we will send you a clear quote.

Does living near the coast affect gutter sealing in Thurso?

Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.

Can you match the sealant colour?

Normally, yes. White, clear and grey are common, and other colours are available for many products, and we will agree it with you first.

Do you work on high-level gutters?

Single-storey work is the most straightforward. For anything higher, we will confirm what access is needed once we know more.

Do you install new fascias or gutters?

That’s not something we do. Our work is sealing joints and replacement is a job for an installer.

Is gutter cleaning part of the job?

We clean the joints we are sealing and clear debris we find nearby. Cleaning the whole run is a different job.

Where is Mr Mastic based?

Our base is in Crawley, and we cover South East England, London and all of Scotland.

How do I get a quote for gutter sealing in Thurso?

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.

Looking after it afterwards

Good habits help new joints last longer. A few tips:

  • Keep an eye out for wet patches below a joint
  • Keep downpipes clear
  • Clean out the gutters once or twice a year
  • Sort out a dripping joint early

Check the joints after heavy rain now and then. Drips are easiest to spot while it’s raining.

The sooner a gutter leak is sealed, the less water reaches the wall. We will let you know if the gutter needs more than sealant.
