- Plants rooting in failed movement joints
- Joints pointed up with cement by mistake
- Damp patches traced to an open external joint
What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours to a few days, depending on the length of joint and the access and we leave things clean and tidy. Somewhere like Hazelbank 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.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Try not to wet indoor joints just before the visit
- Tell us about any previous sealing or DIY attempts

External mastic in Hazelbank
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We take the old material out and do it properly. We work on façade panels, render & cladding joints and copings & trims, and common reasons people get in touch are leaking joints around cladding and façade panels and damp patches traced to an open external joint.
Outside joints can only be sealed when they’re dry, so work in Hazelbank depends on the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
Whatever the size of the job, you get the same 12-month guarantee in Hazelbank and across South Lanarkshire.

Signs you need external mastic in Hazelbank
Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. The joint cannot move, so the wall cracks somewhere else instead.
The problems people usually mention when they call are:
- Gaps where render, brick and frames meet
- Water getting into walls through failed joints
- Failed sealant between panels on a façade
- Plants rooting in failed movement joints
Around Hazelbank, as everywhere, external mastic is only as good as the preparation behind it.

Common questions in Hazelbank
I let a flat near Lanark station. Can you help?
Yes, landlords and agents are among the people we work for. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will send you a clear quote.
Do you cover smaller places like Hazelbank?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
Can you seal joints between render and window frames?
Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces, primed where needed.
Will the new joint stand out?
The aim is a neat, even joint in a colour that suits the wall. Colour is agreed with you before we begin, matched as closely as the range allows.
How do I get a quote for external mastic in Hazelbank?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before we start.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
How the job changes by surface
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. A primer goes on where the product requires one before the bead.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. Where one has been mortared, we cut it out and reseal it with sealant where it can be done safely.
Hazelbank buildings and the weather
Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
For landlords with property near Lanark station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Avoid pressure-washing directly into sealant joints
- Check external joints each spring
- Have failed joints looked at early
- Point out the joints to other trades
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
