Common problems we fix in Kelso
Leaves and moss hold water in the gutter. Water that cannot drain works its way through a weak joint and leaks out.
The problems people normally mention when they call include:
- Damp patches inside below a leaking gutter
- Fascia boards with gaps between them
- Garage door frames letting rain in
- Earlier gutter repairs that have peeled off
In and around Kelso, as anywhere, good gutter sealing starts with a clean, dry, properly prepared joint.
Questions to ask before you book
- Which colour the sealant will be
- The length of the guarantee
- How the surfaces are prepared before sealing
- Whether VAT is included
About our gutter sealing in Kelso
Many dripping gutters are just a failed joint or end cap. We clean out the joint, dry it and reseal it with a sealant made for guttering. If the gutter itself has failed, we say so. Common call-outs are for damp on an inside wall under a dripping gutter and trim joints where the sealant has failed, across uPVC fascias, gutter joints and garage door frames.
Outside joints can only be sealed when they’re dry, so work in Kelso depends on the weather. Tell us how to reach each wall, gutter and roofline.
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.

Outside joints around Kelso
Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex. 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.
Schools such as Kelso High School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What happens if it’s left?
Replacing guttering is a much bigger job than sealing joints. If the gutter is sound and the drip is a joint a reseal is all it needs. If it has failed, we’ll tell you. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.

What we do, step by step
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours, depending on the number of joints and the access. Outside jobs in Kelso need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- First we agree which joints need sealing.
- Each joint is cleaned and any old sealant removed.
- The joints are dried.
- The sealant is applied and finished.
- The joints are checked once sealed.
Before we arrive
- Mention any sign-in or site rules at work premises
- Clear the area around the work
- Let us know if you’ve seen damp or leaks

Can you quote for more than one area?
Of course. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.

I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
What affects the cost of gutter sealing
Every job gets its own quote. These are the things that affect it:
- The product the joint needs
- Whether the work is at height
- The amount of work
- Any working-time requirements on site
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What to tell us for a quote
To make quoting easier, please include:
- The type of property
- Access, such as stairs, a lift or height
- Any previous sealing or DIY work
- Where the job is, and your postcode
Need a quote? Please email us at info@mrmastic.co.uk and tell us about the job. We’ll explain what we’d do and give you a clear quote before work begins.
