External mastic in The Murray, done properly
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. We work on render & cladding joints, façade panels and copings & trims, and the jobs we see most are moss and dirt in joints with no sealant left and cracked joints where brick meets render or frames.
Outside joints can only be sealed when they’re dry, so work in The Murray depends on the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
Every job is covered by our 12-month guarantee, wherever you are in South Lanarkshire.

Why it’s worth doing now in The Murray
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way and it means sorting access once. Around The Murray, water from a failed joint in an older stone home can soak into timber and plaster.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please drop us a line at info@mrmastic.co.uk and we will talk you through it.

Surface by surface
Concrete and blockwork
Big joints in concrete need careful depth control. We size the backing rod to the gap so the sealant is not too deep.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. We reseal them with a low-modulus sealant over backing rod coloured to suit the wall.

How the visit works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours to a few days, depending on the length of joint and the access. Outdoor work around The Murray depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Clear the area around the work
- Let us know about parking restrictions
- Plan for the work area to be out of bounds to pets and children

Signs you need external mastic in The Murray
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
Look out for any of the following:
- Sealant that has lost its bond to the brick or render
- Gaps where render, brick and frames meet
- Weeds or debris growing in open joints
- Hard, crazed mastic that has stopped moving
For site and facilities teams at buildings such as St Andrew's and St Bride's High School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
