What happens on the day
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours to a few days, depending on the length of joint and the access. In a city area like Polmadie, 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.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children
- For indoor joints, keep the area dry beforehand if you can

How we handle external mastic in Polmadie
On houses, flats and commercial buildings across Polmadie, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. We work on façade panels, render & cladding joints and brickwork movement joints, and common reasons people get in touch are panel joints letting water in and cracked joints where brick meets render or frames.
On a four-storey tenement, gutter joints are a long way from the street, so a leaking joint can run down the stone for months before anyone notices. For a building in Polmadie, access is planned first, and shared parts may need the other owners to agree.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Polmadie questions
How is work on the outside of a tenement in Polmadie normally arranged?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds don’t, and we can quote for the factor or the owners directly.

Walls and rooflines in Polmadie
Much of Glasgow is built from red and blond sandstone, and porous sandstone needs a sealant that won’t mark it. Polmadie is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out.
For site and facilities teams at buildings such as St Margaret Mary's Secondary School, larger buildings have long runs of movement joint that eventually need resealing. Historic houses such as Provand's Lordship, about 3.2 miles north, show how far back building around Polmadie goes, and older homes nearby need a sealant that suits their walls.

When to call us in Polmadie
If plants are growing out of a joint, the sealant has normally failed or was never there. Dirt and roots then trap moisture in the joint and speed up the damage.
The most common problems we see are:
- Movement joints with cracked, split or missing sealant
- Hard, crazed mastic that has stopped moving
- Damp patches traced to an open external joint
- Sealant pulling away from one side of the joint
If you let a flat or house near Croftfoot station, split movement joints are easy to miss on a rental until damp shows inside.
What your quote should include
- Are they insured?
- How the surfaces are prepared before sealing
- How long the guarantee is
- Whether VAT is included
Different surfaces, different methods
Concrete and blockwork
The face of concrete or block is often dusty, so preparation is key. A primer goes on where the product requires one.
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

What happens if it’s left?
A failed movement joint lets water into the wall and can run behind render or cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. Wind-driven rain gets into any failed joint on the outside of a city building, and in Polmadie, damp can spread through stone and plaster before anyone sees it.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, drop us a line at info@mrmastic.co.uk and we will give you an honest view and a quote.
