What we do, step by step
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from an hour or two to a few hours. Outside jobs in Sandwick 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. Work indoors is not affected.
- We start by tracing the leak and checking the gutter itself is sound.
- Old sealant and dirt are removed from the joint.
- We make sure the joint is dry before sealing.
- We seal the joint with a sealant made for gutters and outdoor use.
- The run is checked and any debris near the joints is cleared.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Mention any tricky access
- Tell us if parking is tricky

Related advice
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Look for streaks or damp on the wall below gutters
- Clean out the gutters once or twice a year
- Do not leave a sagging gutter
- Keep downpipes clear
Leave the new sealant to cure as we advise before poking or cleaning near it.
Leaking gutter joints get worse over time. Water keeps hitting the same part of the wall and that can cause damp inside.

Questions from Sandwick
Will you come out to Sandwick?
Yes. Sandwick is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland, including the islands, where work is planned around ferry crossings. Let us know about access, parking and anything unusual about getting there when you book.
Is Sandwick in your area for gutter sealing?

I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Where are you based?
We are based in Crawley, and we work across South East England, London and Scotland.
Do you work for hotels and businesses?
Yes. We’ve worked for hotels, offices and other businesses and we are fully insured.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

When to call us in Sandwick
Water spilling over a blocked gutter is often mistaken for a leak. A blocked downpipe makes water back up so we check the cause first.
It’s worth asking for a quote if you see:
- Internal damp traced to a gutter joint
- Wet patches on the wall under a gutter joint
- Failed sealant on a garage door frame
- Quick sealant fixes on gutters that didn’t last
Whether the job is in Sandwick itself or nearby, the right material for each joint matters as much as a neat finish.

What gutter sealing looks like in Sandwick
Sandwick is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on gutter, fascia and roofline joints, especially on the side facing the sea. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
Around Sandwick, as everywhere, gutter sealing is only as good as the preparation behind it.

How the job changes by surface
Gutter joints
When a joint drips, the gutter is often still sound. Sealing the joint often stops it.
Gutter end caps
A leaking end cap sends water straight down the wall. It’s a small job to fix.
