Gutter sealing in Firth, done properly
Sealant only bonds to a clean, dry joint. So the old sealant and grime come out first, then dry the joint before sealing. We work on gutter joints, soffit joints and gutter end caps, and the jobs we see most are internal damp traced to a gutter joint and trim joints where the sealant has failed.
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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

What the job involves on each surface
uPVC fascias
Fascia board joints can open up. We seal them neatly with a matching sealant where possible.
Gutter joints
Joints between gutter lengths are the most common leak point. They’re cleaned out, dried and resealed.
Leave it or put it right?
A dripping gutter joint keeps wetting the same patch of wall. Left, it can stain walls and lead to damp, so it’s worth sealing early. In an older home around Firth, damp from a failed joint can get into timber and plaster.

What happens on the day
When we arrive, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. Most jobs take a few hours, depending on the number of joints and the access. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- 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.
- An exterior or gutter sealant is applied to the joint.
- We check the run and clear any debris we find while we’re there.
Before we arrive
- Mention any tricky access
- Try not to wet indoor joints just before the visit
- Clear items away from the joints we are working on

Outside joints around Firth
Firth is within about 2 miles of 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 joints where harling meets other materials need a sealant that can grip and flex.
Around Firth, as everywhere, gutter sealing is only as good as the preparation behind it. For jobs in and around Firth, choosing the right material for each joint is as important as a tidy finish.

Firth questions
Does living near the coast affect gutter sealing in Firth?
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.
Can you do gutter sealing in Firth?
Yes, Firth is within the area we cover. Our work covers the whole of Scotland. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing, and we will give you a clear quote.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us and we’re fully insured.
What guarantee comes with the job?

What information do you need?
A short description and the location, plus photos if you have them. If we need more, we will ask.
Can landlords and businesses book you?
Yes, regularly. Several properties can be quoted together, and between tenancies is a good time for the work.
Do you work on high-level gutters?
Low gutters are simple to reach. If it’s higher up, let us know and we will confirm the access.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Check the gutters during heavy rain
- Clear leaves and moss from the gutters
- Have sagging gutters refixed early
- Keep an eye out for wet patches below a joint
Keep the gutters clear of leaves and moss so water doesn’t sit on the joints. Water left in a gutter tests every joint.
A leaking stop end is best sealed before the wet months. A winter of drips can lead to damp patches inside.
Honest limits
We’ll always be straight with you, so here’s what new sealant won’t do:
- Problems with the roof covering
