External mastic in Addiewell
On houses, flats and commercial buildings across Addiewell, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean joint faces and the right depth. We work on concrete & block, façade panels and joints between brick and frames, and the jobs we see most are leaking joints around cladding and façade panels and hard, crazed mastic that has stopped moving.
In and around a place like Addiewell, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

How we quote for external mastic
We do not publish a price list. What we look at:
- The product the joint needs

The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and send you a clear quote before any work starts.

A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- The problem you’ve noticed
- If it’s domestic, commercial or a hotel
- How we’d reach the joints
- Photos by email, if that’s easy
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we’ll talk you through the work and give you a clear price.
FAQs for Addiewell
Do you cover smaller places like Addiewell?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you do external mastic in Addiewell?
Yes, Addiewell is within the area we cover. We work across all of Scotland. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
What is backing rod for?
That’s backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides, which would stop it stretching.
Do you have insurance?
Yes. We are fully insured, and we’ve been doing sealant work for more than 20 years.
Do you guarantee your work?
Yes: twelve months. If anything is not right with the work within the year, let us know and we will sort it.
Can you seal over the old sealant?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Can tenants book the work?
Yes. Ask your landlord first, and we can send them the quote if that helps.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we’re using.
For landlords and businesses
Hotels need rooms back in use, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
We also work for property managers and facilities teams in Addiewell and across West Lothian. We can quote a run of properties together, and we are fully insured.
Aftercare tips
So the new joints stay in good condition:
- Deal with leaking gutters that soak the joints below
- Keep high-pressure jets off the joints
- Walk round the building once a year and look at the joints
- Get split or bare joints resealed while the damage is small
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.
Why act early in Addiewell
Sealing over the top of old mastic does not hold for long. The new layer can’t bond properly to old, weathered material, so we always take the old sealant out. Around Addiewell, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, drop us a line at info@mrmastic.co.uk and we’ll give you an honest view and a quote.
What you get with us
- We’re fully insured

Surface by surface
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.
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. We prime where the sealant needs it before the bead.
How it works
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes anything from a few hours to several days, depending on the building. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- 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.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints
- Mention any parking rules near the property

Advice
External mastic in Addiewell: local notes
Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex. 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.
Historic houses such as Howden House, about 4.8 miles north-east, show how far back building around Addiewell goes. For landlords with property near Addiewell station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
