How we handle gutter sealing in North Lochs
Water dripping from a gutter joint can stain walls and soak the ground below. Resealing the joint is often all it needs if the gutter isn’t damaged. Common call-outs are for internal damp traced to a gutter joint and gaps along fascia and soffit joints, across soffit joints, garage door frames and gutter end caps.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.
Each job carries a 12-month guarantee.

Why it’s worth doing now in North Lochs
Leaving a leaking end cap can send water down the wall all winter. Resealing it is a quick job before the damage spreads. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Combining jobs into one visit is normally more efficient than separate visits. You will get one clear quote for the whole job.

Outside joints around North Lochs
North Lochs 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. 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.
In and around North Lochs, as anywhere, good gutter sealing starts with a clean, dry, properly prepared joint.

North Lochs: your questions answered
Does the coastal weather in North Lochs affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Is North Lochs within the area you cover?
Yes, we do. Our work covers the whole of Scotland, islands included, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you work on high-level gutters?
Low-level work is easiest. For anything higher, we’ll confirm what access is needed once we know more.
Do you install new fascias or gutters?
No. We seal leaking joints, end caps and trims. Replacement needs a gutter installer or roofer.
What does gutter sealing cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
How long before the joint can be used?
That depends on the sealant used, so follow the cure time we give you when we finish.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Work for landlords, hotels and businesses
Letting agents and landlords in North Lochs can book us as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Different surfaces, different methods
Roofline trims
Trim joints are cut out and resealed suited to the material.
Gutter joints
A gutter joint has to cope with movement and standing water. A dedicated gutter sealant suits them.
Signs you need gutter sealing in North Lochs
Sagging sections pull joints apart. Resealing a sagging joint will not last, so the gutter needs refixing first.
Keep an eye out for these signs:
- Old gutter sealant that has let go
- Damp on an inside wall under a dripping gutter
- Dripping gutter ends
- Open joints in fascias and soffits
If you live in an older home near Parish Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

How it works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours, depending on the number of joints and the access, and the area is left clean. For a place like North Lochs, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start by tracing the leak and checking the gutter itself is sound.
- We clean out the joint and take out the old sealant.
- The joint is dried, because sealant won’t bond to a wet surface.
- We seal the joint with a sealant made for gutters and outdoor use.
- We check the run and clear any debris we find while we are there.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before
- Clear items away from the joints we’re working on

Advice
Looking after it afterwards
So the new joints stay in good condition:
- Keep the gutters clear of debris
- Keep downpipes clear
- Keep ladders off the guttering
- Sort out a dripping joint early
Clear the gutters once or twice a year so water doesn’t sit on the joints. Standing water strains every seal.
Once roofline sealant splits, water can get behind it. Resealing early protects the boards.
