External mastic for homes and businesses in Old Drumchapel
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We take the old material out and do it properly. We’re often asked to deal with hard, crazed mastic that has stopped moving and failed sealant between panels on a façade, on render & cladding joints, façade panels and copings & trims.
Scotland’s cities also have plenty of modern blocks with rendered or clad walls and sealed movement joints. Around Old Drumchapel, as anywhere, those joints dry out and crack over time, letting water behind the face of the building.
Your job is guaranteed for a year, as with all our work.

What sealant work cannot fix
We won’t take on work that won’t last, so these are the limits:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cutting new joints into brickwork, which is building work rather than sealant work
- Failed render or damaged cladding panels
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly.
Surfaces we seal

Work for landlords, hotels and businesses
We work for landlords and letting agents as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Walls and rooflines in Old Drumchapel
The Tenements (Scotland) Act 2004 sets out how owners share the upkeep of common parts like the roof and outside walls, and many buildings use a factor to arrange it. Your title deeds say which parts are shared. The west of Scotland is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out.
Rented homes near Drumchapel station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. Managing a site like Saint Andrew's High School? Then its movement joints, gutters and trims need looking after like any other building’s.

How the visit works
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes a few hours to a few days, depending on the length of joint and the access from start to finish. Inside a flat in Old Drumchapel, the job is planned with you; outside, shared parts may need the factor or other owners involved. Tell us which applies when you book.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- For indoor joints, keep the area dry beforehand if you can
- Plan for the work area to be out of bounds to pets and children

Copings and trims
A failed coping joint lets water into the top of the wall. Sealing them early saves the wall below.
Render joints
Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.
Leave it or put it right?
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together. Scottish rain finds any gap around a frame or wall joint, and in a tall building in Old Drumchapel, damp can travel a long way before it shows.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

- The problem you’ve noticed

What we’re called out for in Old Drumchapel
Using the wrong sealant is another common reason. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, so it pulls away from the edges.
The problems people normally mention when they call include:
- Sealant pulling away from one side of the joint
- Water getting into walls through failed joints
- Failed sealant between panels on a façade
- Movement joints filled with mortar instead of sealant
If you live in an older home near St David's Parish Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

Common questions in Old Drumchapel
Can you help a landlord with a rental near Drumchapel station?
Yes, we work for letting agents and landlords. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before any work starts.
How do repairs to the shared parts of a tenement in Old Drumchapel get organised?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 covers the common parts where the deeds don’t, and we can quote for the factor or the owners directly.
Can I add another job to the visit?
Yes, we can. More than one area can be quoted together.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
When will the joints need doing again?
There’s no fixed answer: sunny, exposed elevations and busy joints wear faster. A yearly look will tell you when they need doing. Our work comes with a 12-month guarantee.
Will the new joint stand out?
The sealant colour is picked to suit the wall so the joint blends in. There’s a wide choice of exterior colours.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
