External mastic for homes and businesses in Hawkhead
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a colour to suit. We work on brickwork movement joints, copings & trims and façade panels, and people most often call us about plants rooting in failed movement joints and hard, crazed mastic that has stopped moving.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Outside joints on exposed walls work hard, so they need a sealant that moves with the building.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
Why deal with it now?
Resealing a run of joints in one go is normally better than patching one at a time. They’ve weathered the same way. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Wash walls gently around the sealant
- Point out the joints to other trades
- Walk round the building once a year and look at the joints
- Fix overflowing gutters above sealed joints
Keep pressure washers away from the sealant. High-pressure water can lift the edges.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
External mastic in Hawkhead: local notes
Much of Glasgow is built from red and blond sandstone, and porous sandstone needs a sealant that won’t mark it. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Letting a property close to Hawkhead station? Then split movement joints are easy to miss on a rental until damp shows inside. Managing a site like St Andrew's Academy? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Around Hawkhead
Locally, jobs take us to homes and businesses close to Barshaw Park and the streets around them. Hawkhead’s nearest station is Hawkhead station, roughly 0.8 miles north-west of the centre. Other landmarks nearby include Hawkhead Castle (within half a mile south-east) and Silverburn Shopping Centre (1.9 miles south-east).
DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Common problems we fix in Hawkhead
Some movement joints have been pointed up with mortar. The joint can’t move, so the wall cracks somewhere else instead.
Most people get in touch when they notice something like this:
- Gaps where render, brick and frames meet
- Leaking joints around cladding and façade panels
- Damp patches traced to an open external joint
- Moss and dirt in joints with no sealant left
Pollok House, about 2.6 miles east, is one of the historic houses in the wider area around Hawkhead.

The process
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours for a handful of joints, longer for a whole elevation, depending on the amount of work. Outside jobs in Hawkhead need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Tell us if parking is tricky
- Mention any sign-in or site rules at work premises
- Clear the area around the work

Honest limits
To be straight with you, there are a few things sealant will not fix:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracks in the bricks or render themselves, away from the joints
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before you book.

FAQs for Hawkhead
Do you cover smaller places like Hawkhead?
Yes. Hawkhead is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Can you do external mastic in Hawkhead?
Yes, Hawkhead is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply email us at info@mrmastic.co.uk.
Do you use backing rod?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. That way it bonds to the two sides only and can stretch.
Will the new joint stand out?
We aim for a joint that suits the wall rather than one that jumps out. We will talk through colour options before work begins from the range available.
How long should I leave it?
Different products cure at different speeds, so follow the cure time we give you.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Can you reach joints on upper floors?
It depends on the building. Tell us the height, the number of joints and what’s below them and we will confirm how they can be reached safely.
