Gutter sealing in Dunbar
Garage door frames let rain in when the sealant around them fails. The frame joint is cut out and resealed using a sealant made for outdoor use. If you’re dealing with gaps along fascia and soffit joints and garage door frames letting rain in, we can put it right, on gutter end caps, roofline trims and soffit joints alike.
External sealant needs dry surfaces, so outdoor work around Dunbar is planned around the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
All of our work is guaranteed for twelve months.

The process
Every visit runs the same way: we check the joints, protect the area around them, do the work and clear up. Most jobs take a few hours, depending on the number of joints and the access. For a place like Dunbar, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- First, we find the drip and check the gutter isn’t cracked or sagging.
- We clean out the joint and take out the old sealant.
- We make sure the joint is dry before sealing.
- 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’re there.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Mention any parking rules near the property
- Move anything stored near the joints

Common questions in Dunbar
Do you cover smaller places like Dunbar?
Yes. Dunbar is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Does the coastal weather in Dunbar affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. Then email us at info@mrmastic.co.uk.
Is it OK to seal over old sealant?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Dunbar, along with the rest of our area.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Can you fit new guttering?
No. We seal joints and replacement is a job for an installer.
Can I choose the sealant colour?
Yes. White, clear and grey are common, and other colours are available, and we will agree it with you first.
What gutter sealing looks like in Dunbar
Dunbar 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
If you live in an older home near Abbey Church of Scotland, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Looking after it afterwards
A little care helps the new joints last. We recommend:
- Glance at the soffit joints now and then
- Keep downpipes clear
- Deal with a drip before winter
- Do not leave a sagging gutter
Leave the new sealant to cure as we advise before poking or cleaning near it.
Early sealing limits how much water hits the wall. If we find a bigger problem, we’ll tell you.
Different surfaces, different methods
Gutter joints
A gutter joint has to cope with movement and standing water. A dedicated gutter sealant suits them.
Gutter end caps
Drips from a stop end run down the brickwork. It’s a small job to fix.
Why act early in Dunbar
A dripping stop end can soak the wall right through the wet months. It’s a small job to put right before the damage spreads. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
Why us?
- We agree the colour with you first
- Quality sealants from Arbo and Everbuild
- Colour picked to suit the job
- Approved under the ARBOMaster scheme

Keep an eye out for these signs:
- Gaps along fascia and soffit joints
- Earlier gutter repairs that have peeled off
- Stop ends leaking at the end of a run
- Drips from gutter joints and end caps
If you let a flat or house near Dunbar station, leaking gutter joints on a rental are best caught before they stain the walls.
