How external mastic works in Angus
Getting the depth right is half the job. 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, render & cladding joints and concrete & block, and people most often call us about failed seals between different materials and sealant that has lost its bond to the brick or render.
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 we start. The work generally takes anything from a few hours to several days, depending on the building.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.

Near you in Arbroath
Typical jobs here are in homes near Arbroath High School, Knox's Church and The Corn Exchange pub and the streets around them. There’s a railway station in Arbroath itself: Arbroath station. Other landmarks nearby include Arbroath Signal Tower Museum (0.6 miles south) and Arbroath Infirmary (0.6 miles south).
Walls and rooflines across Angus
In Angus, external mastic work takes in houses, flats and commercial buildings, from Arbroath, Forfar and Carnoustie to the quieter places in between. Outside joints can only be sealed when they’re dry, so the work is planned around the weather.
Homes in Scotland come with their own details: sash and case windows, harled walls and, in the towns and cities, tenement flats. We work across Scotland, including Angus. Angus includes coastal places, where outside joints face more wind, rain and salt than they would inland. Walls facing the sea are generally the first to need attention.
Arbroath: Managing a site like Arbroath High School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Rented homes near Arbroath station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.
Why act early?
Resealing a run of joints in one go is usually better than patching one at a time. Joints of the same age tend to fail together, and access only has to be arranged once.
Questions to ask before booking
- Who does the work, and how experienced they are
- Are they insured?
- Is the old sealant removed completely?
- Is VAT in the price?
Landlord and commercial work in Angus
Housing providers, facilities teams and property managers book us too across Angus. Several sites can be quoted together, and we’re fully insured.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Why it fails
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it can’t stretch and tears as soon as the joint widens.
The problems people usually mention when they call are:
- Failed seals between different materials
- Weathered mastic that no longer stretches
- Movement joints with cracked, split or missing sealant
- Damp patches traced to an open external joint
How the job changes 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.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. We reseal them with a low-modulus sealant over backing rod coloured to suit the wall.
When something else is needed
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Structural movement, which needs a surveyor or engineer
- Damp that is not coming from the joint
- Loose or hollow render, which needs re-rendering
Your questions about external mastic in Angus
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
How long does the job take?
Typically it takes anything from a few hours to several days, depending on the building. Bigger jobs take longer.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Is it OK to fill a movement joint with cement?
No. A mortar-filled joint cannot move, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
Why is there a gap in my brick wall?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
How often do external joints need resealing?
There’s no fixed answer: sunny, exposed elevations and busy joints wear faster. A yearly look will tell you when they need doing. Our work comes with a one-year guarantee.
