How we handle gutter sealing in Stornoway
We don’t replace gutters, fascias or roofs. What sealant does is close joints and it can’t mend broken brackets, split sections or blocked downpipes. If you have drips from gutter joints and end caps and damp on an inside wall under a dripping gutter, we can help, whatever the surface.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. Newer houses need their movement joints and roofline trims kept sound.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

What affects the cost of gutter sealing
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
- The type of sealant required
- Any working-time requirements on site
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- Photos by email, if that’s easy
- The rough size of the job
- If someone has resealed it before
- The problem you’ve noticed
We quote each job on its own. Just email us at info@mrmastic.co.uk with the details, and pictures are welcome.
When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- Water backing up from a blocked pipe
- Guttering that needs replacing
- Leaks from the roof rather than a joint
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer.

Signs you need gutter sealing in Stornoway
When a gutter sags, its joints open. Sealing won’t hold if the gutter keeps dropping, so the gutter needs refixing first.
The most common problems we see are:
- Open joints in fascias and soffits
- Rain getting in around a garage door
- Stop ends leaking at the end of a run
- Cracked sealant along roofline trims
In and around Stornoway, as anywhere, good gutter sealing starts with a clean, dry, properly prepared joint.

Advice
How the job changes by surface
Roofline trims
We seal the trims, not the roof. A roofer deals with the roof itself.
Gutter end caps
Drips from a stop end run down the brickwork. It’s a quick reseal.
FAQs for Stornoway
Does living near the coast affect gutter sealing in Stornoway?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
Can you do gutter sealing in Stornoway?
Yes. Our work covers the whole of Scotland, and Stornoway is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing, and we will send you a clear quote.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Can tenants book the work?
Of course. Check with your landlord; we can send the quote to them too.
Do you replace gutters or fascias?
No, we reseal joints, end caps and trims. Replacement needs a gutter installer or roofer.
What guarantee comes with the job?
Our 12-month guarantee applies on every job.
How to look after the new joints
After the cure time, these simple habits help:
- Don’t lean ladders against the gutter itself
- Look for streaks or damp on the wall below gutters
- Check the gutters during heavy rain
- Don’t leave a sagging gutter
Leave the new sealant to cure as we advise before poking or cleaning near it.
A leaking garage frame lets water reach stored items. A reseal sorts it.
DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Stornoway buildings and the weather
Stornoway is within about 1 mile of 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 weather, with its wind and salt spray, is tough on gutter, fascia and roofline joints.
Whether the job is in Stornoway itself or nearby, the right material for each joint matters as much as a neat finish.
