Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
About our gutter sealing in Darnick
Sealant only bonds to a clean, dry joint. That’s why we take out the old sealant and dirt first and the joint is dried before the new sealant goes in. We work on uPVC fascias, gutter joints and gutter end caps, and people most often call us about damp patches inside below a leaking gutter and wet patches on the wall under a gutter joint.
In and around a place like Darnick, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering.
All our work is covered by our one-year guarantee, wherever you are in the Scottish Borders.

Darnick: your questions answered
I let a flat near Tweedbank station. Can you help?
Yes, rental work is part of what we do. You can email us at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before any work starts.
Is Darnick within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
How long will you be here?
It depends on the size of the job, but as a guide it takes a few hours, depending on the number of joints and the access. We will give you a better idea when we quote.
Can a leaking gutter joint be sealed?
In many cases, yes. Cleaning, drying and resealing the joint usually works. If the section is split or warped, it needs replacing.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
What does gutter sealing cost?
It depends on the job, so we quote each one individually. For a quick quote, email us at info@mrmastic.co.uk with a short description of the job.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Glance at the soffit joints now and then
- Watch the wall under the gutters for staining
- Keep the gutters clear of debris
- Don’t leave a sagging gutter
A sagging gutter needs its brackets checked. Movement will pull the joints open again.
Rain getting in round a garage door frame can damage what’s stored inside. A reseal sorts it.
Do you need gutter sealing in Darnick?
Gutter joints depend on seals that wear out. Sun and cold make the gutter expand and contract and that movement opens up tired joints.
The problems people usually mention when they call include:
- End caps that drip every time it rains
- Streaks down the brickwork from a leaking joint
- Damp on an inside wall under a dripping gutter
- Fascia boards with gaps between them
In the older streets around Holy Trinity Episcopal Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Questions to ask before you book
- What happens if they find a problem under the old sealant
- What the cure time is
- Whether you can choose the colour
- What product goes in the joint
Different surfaces, different methods
Garage door frames
Garage door frames let rain in when their sealant fails. We cut it out and reseal.
Gutter joints
A gutter joint has to cope with movement and standing water. A gutter sealant made for the job holds best.
What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes an hour or two for a few joints, longer for a full run, and the area is left clean. Outdoor work around Darnick depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- 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.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Let us know if you’ve seen damp or leaks
- For indoor joints, keep the area dry beforehand if you can

Advice
What affects the cost of gutter sealing
Jobs vary more than people expect. The main factors:
- When we can work, for business premises
- How many areas need sealing
- How easy the joints are to reach
- The number and length of the joints
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and give you a clear quote before we start.
What we need to know
When you contact us, these details help:
- Roughly how big the job is
- Access, such as stairs, a lift or height
- Where the job is, and your postcode
- The type of property
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.
Outside joints around Darnick
Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. 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 Tweedbank station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

Around Darnick
The nearest railway station is Tweedbank station, about 0.7 miles north-west. A little further out are Castle Holydean (2.6 miles south) and Borders General Hospital (under half a mile south). For a walk, there’s Bemersyde Moss and Eildon Mid Hill.
Why deal with it now?
Replacing fascias because of open joints is usually unnecessary. Sealing the joints tidies them up as long as the boards are in good condition. 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.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
