About our gutter sealing in Cummertrees
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, garage door frames and roofline trims, and the jobs we see most are cracked sealant along roofline trims and failed sealant on a garage door frame.
External sealant needs dry surfaces, so outdoor work around Cummertrees is planned around the weather. Let us know about access to every wall and roofline.
The work is covered for a year after we finish. If anything is not right with it, send an email to info@mrmastic.co.uk.

What we do, step by step
We bring everything the job needs with us. After a quick look at the joints together, we protect the area and start. It normally takes an hour or two for a few joints, longer for a full run. Outside jobs in Cummertrees need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First we trace the drip and check the gutter is not damaged.
- The old sealant and dirt are cleaned out of the joint.
- The joint is dried before sealing.
- We seal the joint with a sealant made for gutters.
- The gutter is checked and debris around the joints cleared.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Clear items away from the joints we are working on
- Tell us if parking is tricky

Advice
Outside joints around Cummertrees
Cummertrees is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on gutter, fascia and roofline joints, which can dry out and crack sooner where a building faces the weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
For landlords with property near Annan station, leaking gutter joints on a rental are best caught before they stain the walls.

What we are called out for in Cummertrees
Water spilling over a blocked gutter is often mistaken for a leak. If the downpipe is blocked, water has nowhere to go, which is why we look before we seal.
It’s worth asking for a quote if you see:
- Failed sealant on a garage door frame
- Internal damp traced to a gutter joint
- Water dripping where gutter sections meet
- Stop ends leaking at the end of a run
For an older house near a landmark such as Cummertrees Parish Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Questions from Cummertrees
Does living near the coast affect gutter sealing in Cummertrees?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Will you come out to Cummertrees?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Will you clear out my gutters?
We clear what’s around the joints we work on. A full clean of the gutters isn’t part of it.
Is sealant enough for a gutter that has dropped?
Sealant won’t hold a sagging gutter. A gutter installer needs to refix it.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Why deal with it now?
A bead squeezed onto a wet joint might hold for a while, but it soon lets go. Cleaning out and drying the joint first is what makes it last. Out of town in Scotland, exposed walls take a lot of weather, 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.

How we quote for gutter sealing
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Access and height
- How much old sealant there is and how hard it is to remove
- The type of sealant required
- How many areas need sealing
Leaving a failed joint normally makes the job bigger, not smaller. If you are not sure whether it needs doing, send an email to info@mrmastic.co.uk for an honest opinion and a quote.
What we need to know
Before you ask for a quote, have a think about:
- Photos by email, if that’s easy
- Any previous sealing or DIY work
- The rough size of the job
- If it’s domestic, commercial or a hotel
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. When it suits you, send an email to info@mrmastic.co.uk.
Honest limits
We won’t take on work that won’t last, so these are the limits:
- Cracked, split or warped gutter sections
- Leaks from the roof rather than a joint
- Blocked downpipes
If you are not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer before booking.
Joints and surfaces we work on
- Soffit joints
- Gutter joints
- uPVC fascias
- Roofline trims
- Garage door frames
- Gutter end caps
Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Glance at the soffit joints now and then
- Don’t leave a sagging gutter
- Make sure downpipes are not blocked
- Look for streaks or damp on the wall below gutters
Check the joints after heavy rain. It’s the easiest time to see a leak.
If an end cap is dripping, deal with it before winter. A winter of drips can lead to damp patches.
