West Calder External Mastic
We cover West Calder for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and a one-year guarantee.

- Joints pointed up with cement by mistake
- Brick movement joints where the sealant has split
External mastic in West Calder, done properly
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing and we use one wherever it does. If you are dealing with movement joints filled with mortar instead of sealant and plants rooting in failed movement joints, we can put it right, whatever the surface.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Outside joints on exposed walls work hard, so they need a sealant that moves with the building.
There’s a 12-month guarantee on every job, large or small.

The process
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes anything from a few hours to several days, depending on the building from start to finish. Around West Calder, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Let us know about stairs, lifts or work at height
- Tell us if parking is tricky

What the job involves on each surface
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant so the movement is taken up.
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it and keep the sealant to the right depth.

Common problems we fix in West Calder
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
People normally contact us when they notice one of these:
- Rain getting behind render or cladding at a joint
- Cracked joints where brick meets render or frames
- Weeds or debris growing in open joints
- Hard, crazed mastic that has stopped moving

Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Keep movement joints as flexible joints, not mortar
- Keep water from gutters off the wall
- Check external joints each spring
- Point out the joints to other trades
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick.

Why it’s worth doing now in West Calder
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. A stiffer product can damage the joint edge as it fails. In a place like West Calder, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.

West Calder questions
Do you cover smaller places like West Calder?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Can you do external mastic in West Calder?
Yes. We work across all of Scotland, and West Calder is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we will give you a clear price.
How do you reach high-level joints?
It depends on the building. Tell us the height, the number of joints and what’s below them.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Can I do it myself?
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.
Can landlords and businesses book you?
Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.
Are you insured?
Yes. We are fully insured, and we’ve been doing sealant work for more than 20 years.
