Auchenreoch External Mastic
Our applicators work in Auchenreoch on sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Water getting into walls through failed joints
- Rigid filler in a joint that should flex
- Cracked joints where brick meets render or frames
External mastic in Auchenreoch, done properly
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Porous or awkward surfaces are primed where the sealant needs it and we use one wherever it does. Common call-outs are for hard, crazed mastic that has stopped moving and sealant that has lost its bond to the brick or render, on render & cladding joints, copings & trims and brickwork movement joints.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. Newer houses need their movement joints and roofline trims kept sound.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

How it works
On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. The work usually takes a few hours to a few days, depending on the length of joint and the access. For a place like Auchenreoch, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Keep pets and children clear of the area while we work
- Tell us if parking is tricky
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Common problems we fix in Auchenreoch
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
If you can see any of these, it’s time to have the joints looked at:
- Sealant pulling away from one side of the joint
- Joints pointed up with cement by mistake
- Hard, crazed mastic that has stopped moving
- Panel joints letting water in
If you let a flat or house near Lenzie station, outside joints that have cracked can let damp into a rental, so check them between lets.

Auchenreoch buildings and the weather
Auchenreoch 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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Managing a site like Kirkintilloch High School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Landmarks near Auchenreoch
Auchenreoch’s nearest station is Lenzie station, about 3.3 miles south. Nearby you will also find Broomhill Hospital (1.5 miles south-west) and Barony Chambers Museum (2.2 miles south-west). The countryside around Auchenreoch includes Bar Hill and Lenzie Moss.
What happens if it’s left?
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.

Common questions in Auchenreoch
Is Auchenreoch within the area you cover?

Do you have insurance?

Can you quote for more than one area?
Yes. Tell us about everything you’d like done and you’ll get one quote.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
When will the joints need doing again?
It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Ask before painting over external sealant
- Check external joints each spring
- Show decorators and builders where the movement joints are
- Keep water from gutters off the wall
Only paint over the joint if we’ve confirmed the sealant can take paint. Many exterior sealants are not designed to be painted, and paint can crack as the joint moves.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.

- Cutting new joints into brickwork, which is building work rather than sealant work
- Subsidence or other structural problems
