- Internal damp traced to a gutter joint
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Clear leaves and moss from the gutters
- Look for streaks or damp on the wall below gutters
- Glance at the soffit joints now and then
- Make sure downpipes are not blocked
Leave the new sealant to cure as we advise before poking or cleaning near it.
Early sealing limits how much water hits the wall. If we find a bigger problem, we will tell you.
How we handle gutter sealing in Gelston
For gutter sealant to hold, the joint has to be clean and dry. So the old sealant and grime come out first and the joint is dried before the new sealant goes in. We work on gutter joints, roofline trims and uPVC fascias, and people most often call us about end caps that drip every time it rains and rain getting in around a garage door.
External sealant needs dry surfaces, so outdoor work around Gelston is planned around the weather. Tell us how to reach each wall, gutter and roofline.
A 12-month guarantee comes as standard.

Your questions about gutter sealing in Gelston
What guarantee comes with gutter sealing in Gelston?
All our work, in Gelston and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Is Gelston within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
How much does gutter sealing cost in Gelston?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before we start.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
How long will you be here?
As a guide, most jobs take an hour or two for a few joints, longer for a full run. Larger jobs naturally take longer, and we will say how long yours will take.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all.
I rent my home. Can I book you?
Yes. Check with your landlord; we can send the quote to them too.
Do you have insurance?
Yes, we’re fully insured for domestic and commercial work.
Why it’s worth doing now in Gelston
You don’t need new fascias just because the joints have opened. A neat seal closes the gaps if the boards are sound. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.
Why book with us
- A sealant colour to suit the surroundings
- Over 20 years’ experience
- One-year guarantee on every job
- Anti-fungal silicone where joints get wet

Landlord and commercial work in Gelston
Letting agents often deal with us directly. Tell us the address, the job and how access works.
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.
When to call us in Gelston
Water spilling over a blocked gutter is often mistaken for a leak. If the downpipe is blocked, water has nowhere to go so we check the cause first.
Signs it’s time to call us include:
- Trim joints where the sealant has failed
- Damp on an inside wall under a dripping gutter
- Gaps along fascia and soffit joints
- Garage door frames letting rain in
In the older streets around Kirkland Of Gelston, older walls, gutters and the joints where extensions meet them need a flexible sealant.
What your quote should include
- What happens if they find a problem under the old sealant
- How long to leave it before use
- Who does the work, and how experienced they are
- Whether all the old sealant comes out first
Gelston buildings and the weather
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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.

How it works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself usually takes a few hours, depending on the number of joints and the access, depending on the amount of work. Outside jobs in Gelston 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 trace the drip and check the gutter isn’t damaged.
- We remove the old sealant and clean the joint.
- We dry the joint so the new sealant can bond.
- We seal the joint with a sealant made for gutters.
- The gutter is checked and debris around the joints cleared.
How to prepare
- Mention any leaks or damp you’ve noticed
- For business premises, tell us about site rules or sign-in
- Mention any tricky access

When something else is needed
We’d rather tell you now than do work that will not last, so these are the limits:
- Downpipes that are blocked or broken
- Brackets that have snapped or loosened
- Leaks from the roof rather than a joint
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.
