External & façade joints in Auchinairn, East Dunbartonshire
Our applicators work in Auchinairn on sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Weeds or debris growing in open joints
- Movement joints filled with mortar instead of sealant
- Failed sealant between panels on a façade
Work for landlords, hotels and businesses
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
We also work for property managers and facilities teams in Auchinairn and across East Dunbartonshire. Several sites can be quoted together, and we are fully insured.
How we handle external mastic in Auchinairn
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. We work on façade panels, joints between brick and frames and render & cladding joints, and the jobs we see most are joints with sealant missing in places and joints where the bead has come unstuck.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Gutter joints and wall joints take a battering.
Every job is covered by a 12-month guarantee, wherever you are in East Dunbartonshire.

How the job changes by surface
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. We choose the product to suit.
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Never let anyone fill a movement joint with mortar
- Leave the joints unpainted unless we’ve said otherwise
- Walk round the building once a year and look at the joints
- Clear growth from the base of walls and joints
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.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.
The process
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for a handful of joints, longer for a whole elevation and we leave things clean and tidy. Outdoor work around Auchinairn depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Tell us if parking is tricky
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in

Common problems we fix in Auchinairn
If plants are growing out of a joint, the sealant has generally failed or was never there. Roots and dirt hold water against the wall and make things worse.
People usually contact us when they notice something like this:
- Brick movement joints where the sealant has split
- Leaking joints around cladding and façade panels
- Cracked joints where brick meets render or frames
- Water getting into walls through failed joints
If you let a flat or house near Bishopbriggs station, outside joints that have cracked can let damp into a rental, so check them between lets.

Outside joints around Auchinairn
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. With historic houses such as Provand's Lordship (about 2.7 miles south) nearby, there’s older building stock in the area around Auchinairn as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
If you look after a building such as Bishopbriggs Academy, its movement joints, gutters and trims need looking after like any other building’s. For an older house near a landmark such as Colston Wellpark Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few pictures.
How do I get a quote for external mastic in Auchinairn?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Do you guarantee your work?
Yes, always. There’s a 12-month guarantee on every job, wherever you are.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.
How long does external mastic last?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges.
Why act early in Auchinairn
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and agree the price before starting.
