Gutter sealing in Duns: local notes
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. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
In the older streets around Old Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Duns is in the Scottish Borders. Duns gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a one-year guarantee. Duns is one of 89 towns and villages in the Scottish Borders where we work. You can also see our page for Edinburgh, about 35 miles away.
We work across the TD11 postcode area for gutter sealing. Streets in the area include Market Square, Station Road and Murray Crescent, and we cover them all.

Gutter sealing for homes and businesses in Duns
For gutter sealant to hold, the joint has to be clean and dry. That is why we take out the old sealant and dirt first and the joint is dried before the new sealant goes in. If you are dealing with internal damp traced to a gutter joint and stop ends leaking at the end of a run, we can help, whatever the surface.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. On newer homes, the movement joints and roofline trims are what need watching.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Your questions about gutter sealing in Duns
Is gutter sealing in Duns guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Is Duns in your area for gutter sealing?
Yes. We work across all of Scotland, and Duns is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
Can you match the sealant colour?
In most cases you can choose. We will tell you which colours the right product comes in.
Do you work for letting agents?
Yes. We work in homes, commercial premises and hotels.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used.
Do you install new fascias or gutters?
That is not something we do. We seal joints; replacing gutters and fascias needs a gutter or roofline installer.
What the job involves on each surface
Gutter end caps
End caps are resealed where they meet the gutter, after cleaning and drying.
Garage door frames
Failed sealant around a garage door frame lets water in. We cut it out and reseal.

DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
When to call us in Duns
End caps get knocked or pushed by water. Once the seal behind them fails, they drip.
Look out for any of the following:
- Water dripping where gutter sections meet
- Dripping gutter ends
- Failed sealant on a garage door frame
- Damp patches inside below a leaking gutter
For site and facilities teams at buildings such as Berwickshire High School, larger buildings have long runs of movement joint that eventually need resealing.

The process
There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes a few hours, depending on the number of joints and the access in most cases. Outdoor work around Duns depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First, we find the drip and check the gutter isn’t cracked or sagging.
- The joint or trim is cleaned out and old sealant removed.
- The area is dried so the sealant can bond.
- An exterior or gutter sealant is applied to the joint.
- The run is checked and any debris near the joints is cleared.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive
- Clear the area around the work
