- Internal damp traced to a gutter joint
- Streaks down the brickwork from a leaking joint
- Open joints in fascias and soffits
What the job involves on each surface
uPVC fascias
Fascia board joints can open up. They’re sealed tidily with a matching sealant where possible.
Roofline trims
Sealing roofline trims is joint work only. Roofing problems need a roofer.
How we handle gutter sealing in New Lanark
For gutter sealant to hold, the joint has to be clean and dry. That’s why we take out the old sealant and dirt first, then dry the joint before sealing. We work on gutter joints, soffit joints and roofline trims, and common reasons people get in touch are internal damp traced to a gutter joint and old gutter sealant that has let go.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Outside joints on exposed walls work hard.
The work is covered for a year after we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

What happens if it’s left?
A dripping gutter joint keeps wetting the same patch of wall. Left, it can stain walls and lead to damp, so it’s worth sealing early. 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.
Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.

How we quote for gutter sealing
Every job gets its own quote. This is what makes a difference:
- Whether there’s mould to deal with
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
- When we can work, for business premises
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, drop us a line at info@mrmastic.co.uk and we’ll give you an honest view and a quote.

- Access, such as stairs, a lift or height
- What’s wrong with the joints now
- How many joints, rooms or windows are involved
- Whether it’s a home or a business
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.
New Lanark buildings and the weather
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
Schools such as Lanark Grammar School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you live in an older home near New Lanark Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Can you do gutter sealing in New Lanark?
Yes, New Lanark is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and let us know what needs doing, and we’ll give you a clear quote.
Do you cover smaller places like New Lanark?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Is gutter cleaning part of the job?
The joints we seal are cleaned out and clear debris we find nearby. Cleaning the whole run is a different job.
Will sealant fix a dripping gutter joint?
In many cases, yes. Cleaning, drying and resealing the joint generally works. A split or warped section needs replacing.
How much does gutter sealing cost in New Lanark?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before any work starts.
