Gutter sealing in Haroldswick, done properly
We work across Haroldswick on leaking gutter joints and roofline trims. Single-storey and low gutters are simple to reach and if it’s higher up, let us know and we’ll confirm what access is needed. We work on soffit joints, gutter joints and roofline trims, and the jobs we see most are failed sealant on a garage door frame and quick sealant fixes on gutters that didn’t last.
External sealant needs dry surfaces, so outdoor work around Haroldswick is planned around the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
All of our work is guaranteed for twelve months, in Haroldswick and everywhere else we cover.

Aftercare tips
Looking after new joints is easy:
- Have sagging gutters refixed early
- Don’t lean ladders against the gutter itself
- Clear leaves and moss from the gutters
- Check the gutters during heavy rain
Check the joints after heavy rain. It’s the easiest time to see a leak.
Leaking gutter joints get worse over time. The same spot gets soaked every time it rains, which can lead to staining and damp.
The process
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours, depending on the number of joints and the access, depending on the size of the job. Outside jobs in Haroldswick 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. Indoor work goes ahead whatever the weather.
- First we agree which joints need sealing.
- Each joint is cleaned and any old sealant removed.
- The joints are dried.
- We apply exterior or gutter sealant and finish it neatly.
- We check our work before we leave.
Before we arrive
- Move anything stored near the joints
- Let us know about earlier repairs to the joints
- On commercial sites, let us know about site rules

Walls and rooflines in Haroldswick
Haroldswick is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on gutter, fascia and roofline joints, which can dry out and crack sooner where a building faces the weather. Island jobs need planning around ferries and the weather, so give us as much notice as you can.
For an older house near a landmark such as St John's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Haroldswick is in the Shetland Islands. Wherever you are in the ZE2 postcode area, we can carry out gutter sealing at your property. Haroldswick is one of 63 places in the Shetland Islands where we work.

Why act early in Haroldswick
A new garage door is not needed for a leaking frame. Sealing the frame usually stops it, if the frame itself is sound. Around Haroldswick, water from a failed joint in an older stone home can soak into timber and plaster.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Signs you need gutter sealing in Haroldswick
Water spilling over a blocked gutter is often mistaken for a leak. A blocked downpipe makes water back up, which is why we look before we seal.
These are the problems we are asked about most:
- Gaps along fascia and soffit joints
- Dripping gutter ends
- Quick sealant fixes on gutters that didn’t last
- Water dripping where gutter sections meet
In and around Haroldswick, as anywhere, good gutter sealing starts with a clean, dry, properly prepared joint.

Common questions in Haroldswick
Is Haroldswick in your area for gutter sealing?
Yes. Our work covers the whole of Scotland, and Haroldswick is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear quote.
Is gutter sealing in a coastal place like Haroldswick any different?
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.
Do you work for landlords and businesses?
Yes, often. Several properties can go on one quote, and between tenancies is a good time for the work.
How long will you be here?
That depends on how much there is to do, but as a guide it takes a few hours, depending on the number of joints and the access. We will give you a better idea when we quote.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done.
Can tenants book the work?
Yes. Check with your landlord; we can send the quote to them too.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we’re done.
