External mastic for homes and businesses in Cleland
On houses, flats and commercial buildings across Cleland, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean joint faces and the right depth. If you are dealing with hard, crazed mastic that has stopped moving and sealant that has lost its bond to the brick or render, we can help, on concrete & block, brickwork movement joints and copings & trims alike.
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.
Big or small, you get the same 12-month guarantee.

Walls and rooflines in Cleland
Historic houses like Cambusnethan House (about 3.4 miles south) are a reminder that the area around Cleland has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
Historic houses such as Cambusnethan House, about 3.4 miles south, show how far back building around Cleland goes, and older homes nearby need a sealant that suits their walls. Rented homes near Cleland station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

The process
When we arrive, we start by going over the job with you, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. Most jobs take anything from a few hours to several days, depending on the building. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Clear items away from the joints we’re working on
- Let us know about earlier repairs to the joints

What happens if it’s left?
Water gets in through a failed movement joint and can run behind render or cladding. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. In an older home around Cleland, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, email us at info@mrmastic.co.uk for an honest opinion and a quote.

Common problems we fix in Cleland
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
The problems people generally mention when they call include:
- Sealant that has lost its bond to the brick or render
- Joints pointed up with cement by mistake
- Damp patches traced to an open external joint
- Leaking joints around cladding and façade panels
Managing a site like St. Aidan's Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

FAQs for Cleland
Do you work for landlords with property near Cleland station?
Yes, landlords and agents are among the people we work for. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear quote.
Can you do external mastic in Cleland?
Yes. We work across all of Scotland, and Cleland is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing.
Do you work at height?
It depends on the height and the site. Ground-floor joints are simple; for higher ones, send details and we’ll confirm the access.
What is backing rod for?
That is backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only so it can flex with the joint.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do you guarantee your work?
Yes. Every job comes with our one-year guarantee.
Are you fully insured?
Yes. We are fully insured.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Different surfaces, different methods
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.
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.

For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
When it isn’t the sealant
In fairness, there are a few things sealant will not fix:
- Walls that need new movement joints cut into them
- Cracked brickwork or render that needs a builder or plasterer
- Damp that isn’t coming from the joint
If you are not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer.
