What happens on the day
At the end, we look at the finished work together and tell you how long to leave it. The visit itself generally takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. Outdoor work around Hairmyres depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Let us know about stairs, lifts or work at height
- Mention any sign-in or site rules at work premises
- Keep children and pets away from the work area

How we handle external mastic in Hairmyres
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. We work on brickwork movement joints, copings & trims and concrete & block, and people most often call us about hard, crazed mastic that has stopped moving and sealant that has lost its bond to the brick or render.
In and around a place like Hairmyres, 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.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Looking after it afterwards
To keep the joints looking good and working properly:
- Walk round the building once a year and look at the joints
- Deal with leaking gutters that soak the joints below
- Act on the first splits you see
- Do not let climbing plants root in the sealant
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Small splits are the time to act. At that stage it’s a simple cut out and reseal.
Hairmyres: your questions answered
Is Hairmyres within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Hairmyres station. Can you help?
Yes, we work for landlords and letting agents. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before work begins.
What should I tell you?
A short description and the location, plus photos if you have them. We will ask anything else we need to know.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all.
Why is there a gap in my brick wall?
Most straight vertical gaps in brickwork are movement joints. It lets the bricks expand without cracking, and it should be sealed with a flexible sealant.
Is the work guaranteed?
Yes. All our work carries our 12-month guarantee.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
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.
Walls and rooflines in Hairmyres
The west of Scotland is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
Letting a property close to Hairmyres station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Why act early in Hairmyres
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

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.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Landlord and commercial work in Hairmyres
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
When to call us in Hairmyres
A lot of failed joints come down to preparation: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
Any of these means the joints need attention:
- Brick movement joints where the sealant has split
- Movement joints filled with mortar instead of sealant
- Failed seals between different materials
- Rain getting behind render or cladding at a joint
Schools such as Duncanrig Secondary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.
What your quote should include
- What preparation is included
- Whether all the old sealant comes out first
- When the joint can take water or movement
- Whether the sealant suits the joint

When it isn’t the sealant
A few problems are outside what sealant work can do:
- Movement that is more than a sealant joint can take
- Cutting new joints into brickwork, which is building work rather than sealant work
- Render that’s blown, hollow or coming away
If you’re not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer.
