FAQs for Westrigg
Can you do external mastic in Westrigg?
Yes, Westrigg is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
I let a flat near Blackridge station. Can you help?
Yes, landlords and agents are among the people we work for. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear price.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Should I point up the gap in my brickwork?
No. Cement or mortar can’t stretch, so the joint stops doing its job. If it has already been filled, we can usually cut it out and reseal it.
Are you fully insured?
Yes. We’re fully insured for domestic and commercial work.
How long does the job take?
It depends on the size of the job, but most jobs take anything from a few hours to several days, depending on the building. We will tell you when we quote.
How do you reach high-level joints?
It depends on the building. Where joints can be reached safely, we’ll do them. Give us some details and we’ll confirm the access.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in.
About our external mastic in Westrigg
Low-level joints can generally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we will confirm what access is needed. Common call-outs are for failed seals between different materials and damp patches traced to an open external joint, across render & cladding joints, façade panels and joints between brick and frames.
External sealant needs dry surfaces, so outdoor work around Westrigg is planned around the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
We stand behind the work with a one-year guarantee.

Walls and rooflines in Westrigg
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. Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
For landlords with property near Blackridge station, outside joints that have cracked can let damp into a rental, so check them between lets.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Why act early in Westrigg
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. In an older home around Westrigg, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

When to call us in Westrigg
A lot of failed joints come down to preparation: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
The most common problems we see are:
- Weathered mastic that no longer stretches
- Movement joints filled with mortar instead of sealant
- Sealant that has lost its bond to the brick or render
- Joints with sealant missing in places
If you look after a building such as Armadale Academy, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Cracking across the wall rather than at a joint
- Cutting new joints into brickwork, which is building work rather than sealant work
- Damp that is not coming from the joint
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.
Joints and surfaces we work on
- Brickwork movement joints
- Concrete & block
- Render & cladding joints
- Façade panels
- Joints between brick and frames
- Copings & trims
Keeping the joints in good condition
So the new joints stay in good condition:
- Keep water from gutters off the wall
- Clear growth from the base of walls and joints
- Keep high-pressure jets off the joints
- Act on the first splits you see
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
How it works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes anything from a few hours to several days, depending on the building, and the area is left clean. Outside jobs in Westrigg need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- 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.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Move anything stored near the joints
- Let us know about earlier repairs to the joints
