About our gutter sealing in Nerston
We seal leaking gutter joints, end caps, fascia and soffit joints plus roofline trims and garage door frames. It’s joint work, not replacing the gutter. Common call-outs are for damp patches inside below a leaking gutter and leaking gutter joints and stop ends, across roofline trims, gutter joints and garage door frames.
External sealant needs dry surfaces, so outdoor work around Nerston is planned around the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Check fascia and soffit joints for gaps
- Check that water runs out of the downpipes
- Don’t leave a sagging gutter
- Deal with a drip before winter
While checking gutters, glance at the fascia joints too. A small split is quicker to put right.
Once roofline sealant splits, water can get behind it. Sealing it early keeps the boards behind dry and the wall below.
Can I do it myself?
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Honest limits
We won’t take on work that won’t last, so these are the limits:
- Sagging gutters or broken brackets
- Roof leaks, slipped tiles or failed flashing (a roofer’s job)
- Cracked, split or warped gutter sections
If you’re not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer.

What gutter sealing looks like in Nerston
Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
If you look after a building such as St Andrew's and St Bride's High School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Questions from Nerston
Do you work for landlords with property near East Kilbride station?
Yes, we work for letting agents and landlords. Just send an email to info@mrmastic.co.uk and tell us about the property, and we will give you a clear quote.
Do you cover smaller places like Nerston?
Yes, Nerston is covered. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
Can you quote for more than one area?
Of course. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
How much does gutter sealing cost in Nerston?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before we start.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
The process
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself normally takes a few hours, depending on the number of joints and the access, depending on the size of the job. Around Nerston, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We start by tracing the leak and checking the gutter itself is sound.
- We clean out the joint and take out the old sealant.
- We make sure the joint is dry before sealing.
- Gutter or exterior sealant is applied and finished.
- We check the run and clear any debris we find while we’re there.
Getting ready for the visit
- Mention if the joints have been sealed before
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area
