Strathy: your questions answered
Is gutter sealing in a coastal place like Strathy any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Can you do gutter sealing in Strathy?
Yes, Strathy is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
Do you offer different sealant colours?
Generally, yes. White, clear and grey are common, and other colours are available for many products, and we will agree it with you first.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first.
Are you insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
Can I add another job to the visit?
Of course. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Gutter sealing in Strathy
A drip at a gutter joint is easy to ignore, but the water lands on the same spot every time it rains. Sealing it is quick if the gutter is otherwise in good order. If you’re dealing with water running down the wall below the gutter and cracked sealant along roofline trims, we can help.
Outside joints can only be sealed when they’re dry, so work in Strathy depends on the weather. Let us know about access to every wall and roofline.

Gutter sealing in Strathy: local notes
Strathy 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. 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.
Around Strathy, as everywhere, gutter sealing is only as good as the preparation behind it.
Strathy is about 17 miles west of Thurso, in Highland. Strathy gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a 12-month guarantee. Strathy is one of 253 places in Highland where we work.

We also cover the places around Strathy: Portskerra (3 miles east), Melvich (3 miles east), Reay (8 miles east), Am Blàran Odhar (8 miles west) and Forss (13 miles east).

Quotes for gutter sealing in Strathy
We quote each job individually. This is what makes a difference:
- How much old sealant there is and how hard it is to remove
- How easy the joints are to reach
- How many areas need sealing
- Any mould that needs treating
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.
What to tell us for a quote
To help us quote quickly, please include:
- The type of property
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
- A few photos by email, if you can
Every job is quoted individually, so the first step is telling us about yours. Just drop us a line at info@mrmastic.co.uk with the details.
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Watch the wall under the gutters for staining
- Make sure downpipes are not blocked
- Keep ladders off the guttering
- Clear leaves and moss from the gutters
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.

If you manage several properties in or around Strathy, jobs at different addresses can be quoted together. Send us the addresses and the work at each, and photos by email help.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
What happens on the day
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take anything from an hour or two to a few hours. Outside jobs in Strathy need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First, we find the drip and check the gutter isn’t cracked or sagging.
- The joint or trim is cleaned out and old sealant removed.
- The joint is dried, because sealant won’t bond to a wet surface.
- We seal the joint with a sealant made for gutters and outdoor use.
- We look along the gutter and clear debris around the joints.
Preparing for the visit
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed
Getting a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
Related advice
When to call us in Strathy
Debris in the gutter keeps water sitting at the joints. Water that cannot drain works its way through a weak joint and drips through.
The most common problems we see are:
- Earlier gutter repairs that have peeled off
- Stop ends leaking at the end of a run
- Fascia boards with gaps between them
- Wet patches on the wall under a gutter joint
For jobs in and around Strathy, choosing the right material for each joint is as important as a tidy finish.
