How we handle gutter sealing in Greengairs
We seal leaking gutter joints, end caps, fascia and soffit joints plus roofline trims and garage door frames. It’s joint work rather than new guttering. Typical jobs include damp patches inside below a leaking gutter and open joints in fascias and soffits, across garage door frames, soffit joints and gutter joints.
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.
There’s a 12-month guarantee on every job, whatever its size.

Landlords, agents and businesses in Greengairs
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
We work for letting agents and landlords as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
What we do, step by step
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours, depending on the number of joints and the access. Around Greengairs, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- First, we find the drip and check the gutter isn’t cracked or sagging.
- Old sealant and dirt are removed from the joint.
- The joint is dried, because sealant won’t bond to a wet surface.
- Gutter or exterior sealant is applied and finished.
- We look along the gutter and clear debris around the joints.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about parking restrictions
- Mention any sign-in or site rules at work premises

What affects the cost of gutter sealing
We do not publish a price list, because no two jobs are the same. What we look at:
- The number of rooms or windows
- The type of sealant required
- Working hours on commercial sites
- Whether the work is at height
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
What we need to know
To help us quote quickly, let us know:
- If it’s domestic, commercial or a hotel
- What’s wrong with the joints now
- The rough size of the job
- Photos by email, if that’s easy
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. When it suits you, send an email to info@mrmastic.co.uk.
Common problems we fix in Greengairs
Leaves and moss hold water in the gutter. Water that cannot drain works its way through a weak joint and drips through.
Most people get in touch when they notice something like this:
- Failed sealant on a garage door frame
- Trim joints where the sealant has failed
- Open joints in fascias and soffits
- Leaking gutter joints and stop ends
Rented homes near Cumbernauld station change hands often, and a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.

Can you match the sealant colour?

Do you seal gaps in fascias and soffits?

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Greengairs buildings and the weather
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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
