Gutter sealing for homes and businesses in Janetstown
A drip at a gutter joint is easy to ignore, but each shower sends water to the same place. Resealing it is a small job if the gutter is otherwise in good order. We work on gutter joints, uPVC fascias and garage door frames, and people most often call us about drips from gutter joints and end caps and fascia boards with gaps between them.
External sealant needs dry surfaces, so outdoor work around Janetstown is planned around the weather. Let us know about access to every wall and roofline.
Your job is guaranteed for a year, as with all our work.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Watch the wall under the gutters for staining
- Don’t leave a sagging gutter
- Get leaks sealed before the wet months
- Keep downpipes clear
Clear the gutters once or twice a year so water does not sit on the joints. Standing water strains every seal.
Early sealing limits how much water hits the wall. We’ll let you know if the gutter needs more than sealant.
Questions from Janetstown
Will you come out to Janetstown?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Thurso station?
Yes, rental work is part of what we do. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
Do you offer different sealant colours?
Yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before work begins.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can I do 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.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Will there be a smell?
There can be a smell while the sealant cures. Ventilation helps.

What we are called out for in Janetstown
When a gutter sags, its joints open. Sealing won’t hold if the gutter keeps dropping, so the gutter needs refixing first.
If you can see any of these, it’s time to have the joints looked at:
- Stop ends leaking at the end of a run
- Trim joints where the sealant has failed
- Earlier gutter repairs that have peeled off
- Garage door frames letting rain in
Schools such as Thurso High School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
Questions to ask before booking
- How much experience the applicator has
- Is VAT in the price?
- Whether you can choose the colour
- What guarantee comes with the work
Gutter sealing in Janetstown: local notes
Janetstown 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
If you let a flat or house near Thurso station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.
Janetstown is about 3 miles south-west of Thurso, in Highland. Whether you’re in the middle of Janetstown or further out, gutter sealing is available for homes and businesses alike, from flats and houses to offices and hotels. Across Highland, we cover 253 places, Janetstown among them.

Advice
Leave it or put it right?
Replacing fascias because of open joints is generally unnecessary. Sealing the joints tidies them up as long as the boards are in good condition. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Landlord and commercial work in Janetstown
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
