Common problems we fix in Carndu
Gutter joints depend on seals that wear out. Sun and cold make the gutter expand and contract and that movement opens up tired joints.
Keep an eye out for these signs:
- Failed sealant on a garage door frame
- Wet patches on the wall under a gutter joint
- Damp on an inside wall under a dripping gutter
- Open joints in fascias and soffits
In the older streets around St Duthuc's Roman Catholic Chapel, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

About our gutter sealing in Carndu
Gaps along uPVC fascias and soffits look untidy and can let in water and draughts. They’re sealed in a matching colour where one is available. We are often asked to deal with open joints in fascias and soffits and damp patches inside below a leaking gutter, on garage door frames, gutter joints and uPVC fascias.
Outside joints can only be sealed when they’re dry, so work in Carndu depends on the weather. Let us know about access to every wall and roofline.
There’s a 12-month guarantee on every job, whatever its size.

Surface by surface
uPVC fascias
We seal fascia joints, not replace the boards. If boards are damaged, we’ll tell you.
Roofline trims
Sealing roofline trims is joint work only. Roofing problems need a roofer.
Gutter sealing in Carndu: local notes
Carndu is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on gutter, fascia and roofline joints, especially on the side facing the sea. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
Letting a property close to Stromeferry station? Then a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.
Carndu is in Highland. Every kind of property in Carndu can book us for gutter sealing. The work is guaranteed for a year. We cover 253 towns and villages across Highland, large and small.

Near you in Carndu

Why act early in Carndu
If the problem is a blocked downpipe, sealing will not help. We look at what’s really happening and tell you if something else is needed. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Leaving a failed joint usually makes the job bigger, not smaller. If you’re not sure whether it needs doing, send an email to info@mrmastic.co.uk for an honest opinion and a quote.
Why book with us
- A sealant colour to suit the surroundings

Where we work in Carndu
- Garage door frames
- Gutter joints
- Soffit joints
- uPVC fascias

- Roofline trims
What we do, step by step
On the day, we start by going over the job with you. We protect the surfaces around the joints before work begins. Most jobs take anything from an hour or two to a few hours. Outdoor work around Carndu 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 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.
- A gutter sealant is applied to the joint.
- The gutter is checked and debris around the joints cleared.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention any parking rules near the property
- Tell us about any previous sealing or DIY attempts
