How we handle external mastic in Maryhill Park
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We strip the joint back and start again. We are often asked to deal with leaking joints around cladding and façade panels and brick movement joints where the sealant has split, across render & cladding joints, façade panels and concrete & block.
Alongside their tenements, Scotland’s cities have modern blocks with render, cladding and movement joints. Around Maryhill Park, as anywhere, those joints dry out and crack over time, letting water behind the face of the building.
Whatever the size of the job, you get the same one-year guarantee in Maryhill Park and across Glasgow.

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Different surfaces, different methods
Render joints
Water behind render can lead to blown patches. Resealing the joints early keeps water out.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it or an approved alternative. Tell us what the building has when you get in touch.

How the visit works
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and clear up. Most jobs take a few hours to a few days, depending on the length of joint and the access. In a city area like Maryhill Park, parking may be by permit or pay-and-display, so tell us what’s nearby. If you’re in a flat, let us know how we get in at the street door.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.

Advice
Walls and rooflines in Maryhill Park
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. With historic houses such as Tenement House (about 2.7 miles south-east) nearby, there’s older building stock in the area around Maryhill Park as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
If you look after a building such as John Paul Academy, its movement joints, gutters and trims need looking after like any other building’s. Tenement House, about 2.7 miles south-east, is one of the historic houses in the wider area around Maryhill Park.

Maryhill Park: your questions answered
Do you work for landlords with property near Maryhill station?
Yes, rental work is part of what we do. You can send an email to info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before any work starts.
Can you do external mastic in Maryhill Park?
Yes, Maryhill Park is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and let us know what needs doing, and we’ll give you a clear price.
Do you use backing rod?
Backing rod controls the sealant depth and keeps it off the back of the joint. That way it bonds to the two sides only and can stretch.
Do you guarantee your work?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
Is it OK to fill a movement joint with cement?
No. Rigid materials cannot move with the wall, so the joint stops doing its job. If it has already been filled, we can usually cut it out and reseal it.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep soil, plants and ivy away from the joints
- Check the sealant is paintable before painting near it
- Deal with leaking gutters that soak the joints below
- Show decorators and builders where the movement joints are
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Catch it early and you reduce the risk.
For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Signs you need external mastic in Maryhill Park
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
Common reasons people contact us include:
- Movement joints filled with mortar instead of sealant
- Sealant pulling away from one side of the joint
- Panel joints letting water in
- Joints with sealant missing in places
If you let a flat or house near Maryhill station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
