Gutter sealing in Lerwick
A leaking gutter joint marks the wall and wets the ground underneath. Often a reseal is enough, as long as the gutter is sound. If you are dealing with quick sealant fixes on gutters that didn’t last and old sealant on roofline trims that has split, we can help, whatever the surface.
In and around a place like Lerwick, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering.
Whatever the size of the job, it’s backed by our 12-month guarantee in Lerwick and across the Shetland Islands.

Aftercare tips
So the new joints stay in good condition:
- Sort out a dripping joint early
- Have sagging gutters refixed early
- Clean out the gutters once or twice a year
- Watch the wall under the gutters for staining
Look at fascia and trim joints when you’re checking the gutters. A small split is quicker to put right.
Split sealant on fascias and trims lets water in behind. Resealing early protects the boards and the wall below.

Outside joints around Lerwick
Lerwick is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on gutter, fascia and roofline joints, especially on the side facing the sea. 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.
If you live in an older home near St Margaret's Roman Catholic Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

FAQs for Lerwick
Is Lerwick within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland, including the islands, where work is planned around ferry crossings. Let us know about access, parking and anything unusual about getting there when you book.
Do you cover Lerwick for gutter sealing?
Yes. We work across all of Scotland, and Lerwick is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
How long does the job take?
A typical job takes a few hours, depending on the number of joints and the access, including preparation and clearing up. Your quote will say how long we expect yours to take.
Will you clear out my gutters?
We clear what’s around the joints we work on. Full gutter cleaning is a separate job.
Are you insured?
Yes. We’re fully insured, and we have been doing sealant work for more than 20 years.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Can you fit new guttering?
No. Our work is sealing joints and replacement is a job for an installer.
Can you reach high gutters?
Low gutters are simple to reach. If it’s higher up, let us know and we will confirm the access.
Can I do it myself?
What a professional job adds is preparation and the right 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.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

Advice
When it isn’t the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Rotten or damaged fascia boards
- Roof leaks, slipped tiles or failed flashing (a roofer’s job)
- Water backing up from a blocked pipe
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly.

What we are called out for in Lerwick
Sealant on fascias and trims weathers like any outdoor joint. It hardens, shrinks and splits over time.
The problems people normally mention when they call include:
- Leaking gutter joints and stop ends
- Old gutter sealant that has let go
- Old sealant on roofline trims that has split
- Water running down the wall below the gutter
For site and facilities teams at buildings such as Anderson High School, larger buildings have long runs of movement joint that eventually need resealing.
