How we handle external mastic in Kelvingrove
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing. If you’re dealing with joints where the bead has come unstuck and damp patches traced to an open external joint, we can help, on copings & trims, façade panels and brickwork movement joints alike.
Stone-built tenements in Scotland’s cities share their roof, gutters and outside walls between every flat in the building. For a tenement in Kelvingrove, repairs to shared parts are normally agreed between the owners, often through a property factor.
The work is covered for a year after we finish. If anything isn’t right with it, drop us a line at info@mrmastic.co.uk.

Your questions about external mastic in Kelvingrove
Who arranges sealant work on the shared parts of a tenement in Kelvingrove?
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.
Is Kelvingrove in your area for external mastic?
Yes. Our work covers the whole of Scotland, and Kelvingrove is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Are you fully insured?
Yes. We are fully insured.
Can tenants book the work?
Yes. Check with your landlord; we can send the quote to them too.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover Kelvingrove, along with the rest of our area.
Can you seal joints between render and window frames?
Yes. Different materials move at different rates, so the joint between them must be flexible. We choose one that suits both surfaces.
Why act early in Kelvingrove
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost near the open joint, so the damage spreads beyond the joint. In a Scottish city tenement, failed sealant affects more than one flat: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why choose Mr Mastic in Kelvingrove
- White, clear, grey or another colour, product permitting
- A sealant colour to suit the surroundings
- You choose the colour before work begins
- A 12-month guarantee on all work

What else we do in Kelvingrove
When to call us in Kelvingrove
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
The most common problems we see are:
- Hard, crazed mastic that has stopped moving
- Rigid filler in a joint that should flex
- Damp patches traced to an open external joint
- Moss and dirt in joints with no sealant left
If you live in an older home near Kelvingrove Parish Church, an extension built onto an older house moves differently, and the joint between them takes the strain.
What your quote should include
- How much experience the applicator has
- Are they insured?
- How hidden problems are handled
- How long to leave it before use
How it works
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes anything from a few hours to several days, depending on the building, depending on how much there is to do. Parking in city streets around Kelvingrove can be tight or controlled, so it helps to know about permits or nearby bays. For flats, mention the door entry system and any shared-stair arrangements.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- 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.
How to prepare
- On commercial sites, let us know about site rules
- Keep children and pets away from the work area
- Tell us if parking is tricky

External mastic in Kelvingrove: local notes
Much of Glasgow is built from red and blond sandstone, and sandstone is porous, so any sealant against it has to be one that won’t stain or attack it. With historic houses such as Tenement House (about 0.6 miles east) nearby, there’s older building stock in the area around Kelvingrove as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Managing a site like Glasgow Gaelic School? Then its movement joints, gutters and trims need looking after like any other building’s. Rented homes near Exhibition Centre station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Surface by surface
Render joints
The face of render can be soft, so a low-modulus sealant is kinder to the joint edges. We prime where the product needs it.
Copings and trims
Copings expand and contract through the day, so a flexible sealant suits them best year round.
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

There’s no set price list. What we look at:

What we can’t put right
To be straight with you, some problems need a different trade:

- Cracking across the wall rather than at a joint
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly.
