Gutter sealing in Coulport
Sealant only bonds to a clean, dry joint. So the old sealant and grime come out first, then dry the joint before sealing. If you are dealing with water running down the wall below the gutter and failed sealant on a garage door frame, we can help.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. Newer houses need their movement joints and roofline trims kept sound.
You’re covered for a year from the day we finish. If anything isn’t right with it, send an email to info@mrmastic.co.uk.

Outside joints around Coulport
Coulport is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on gutter, fascia and roofline joints, especially on the side facing the sea. Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
Rented homes near Garelochhead station change hands often, and a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.

What affects the cost of gutter sealing

- Whether the work is at height

What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and agree the price before starting.

Photos help, but a description is a good start. Please mention:

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Coulport: your questions answered
Is Coulport within the area you cover?
Yes, Coulport is covered. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I let a flat near Garelochhead station. Can you help?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
What about gutters on a second or third storey?
It depends on the access. Tell us the height and what’s around the gutter and we’ll confirm what’s needed.
Can you quote for more than one area?
Yes, we can. More than one area can be quoted together.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.

In most cases you can choose. We will explain which colours are available and agree one before we start.

The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours, depending on the number of joints and the access and we leave things clean and tidy. Around Coulport, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- We start by tracing the leak and checking the gutter itself is sound.
- Old sealant and dirt are removed from the joint.
- 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 are there.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Tell us if parking is tricky
- For indoor joints, keep the area dry beforehand if you can

How the job changes by surface
Roofline trims
Trims along the roofline are often finished with sealant. Split sealant lets water in.
Soffit joints
Soffit board joints can separate over time. They’re sealed to tidy the line.
Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Tell us the address, the job and how access works.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Looking after it afterwards
To keep the joints looking good and working properly:
- Keep ladders off the guttering
- Deal with a drip before winter
- Check that water runs out of the downpipes
- Look at the gutters while it’s raining
Have a look at the gutter during a downpour. It’s the easiest time to see a leak.
A leaking stop end is best sealed before the wet months. Water down the wall all winter can cause damp.
