DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
How we handle gutter sealing in Wiston
Gaps along uPVC fascias and soffits look untidy and can let in water and draughts. They’re sealed in a matching colour where possible. We’re often asked to deal with old sealant on roofline trims that has split and dripping gutter ends, across gutter joints, soffit joints and roofline trims.
In and around a place like Wiston, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.
There’s a 12-month guarantee on every job.

Why deal with it now?
Replacing guttering is a much bigger job than sealing joints. If the gutter is sound and the drip is a joint, resealing is the sensible fix. If it has failed, we will tell you. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

How the visit works
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours, depending on the number of joints and the access. Somewhere like Wiston may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First, we find the drip and check the gutter isn’t cracked or sagging.
- The joint or trim is cleaned out and old sealant removed.
- We make sure the joint is dry before sealing.
- We seal the joint with a sealant made for gutters and outdoor use.
- We look along the gutter and clear debris around the joints.

Garage door frames
Garage door frames let rain in when their sealant fails. We cut it out and reseal.
Roofline trims
Roofline trims rely on sealant at their joints. When it splits, water can get behind.
Walls and rooflines in Wiston
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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
In the older streets around Wiston Parish Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Your questions about gutter sealing in Wiston
Can you do gutter sealing in Wiston?
Yes, Wiston is within the area we cover. We work across all of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job.
Do you cover smaller places like Wiston?
Yes, we do. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
How long will you be here?
A typical job takes a few hours, depending on the number of joints and the access, including preparation and clearing up. We will confirm how long when we quote.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Do you work on high-level gutters?
It depends on the access. Tell us the height and what’s around the gutter and we’ll confirm what’s needed.
Can landlords and businesses book you?
Yes, regularly. Several properties can be quoted together, and between tenancies is a good time for the work.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Signs you need gutter sealing in Wiston
Sagging sections pull joints apart. Sealing won’t hold if the gutter keeps dropping, so the gutter needs refixing first.
These are the problems we are asked about most:
- Damp on an inside wall under a dripping gutter
- Fascia boards with gaps between them
- Water dripping where gutter sections meet
- Stop ends leaking at the end of a run
Around Wiston, as everywhere, gutter sealing is only as good as the preparation behind it.

What affects the cost of gutter sealing
Jobs vary more than people expect. The main factors:
- The type of sealant required
- How much there is to do
- How many areas need sealing
- Working hours on commercial sites
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
