External mastic in Arbroath, done properly
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing. If you’re dealing with gaps where render, brick and frames meet and rain getting behind render or cladding at a joint, we can help, whatever the surface.
Harled walls are common in Scottish towns like Arbroath, and the joints where harling meets windows, doors and pipes need a sealant that grips and flexes. Rooflines take their share of the weather as well.
You are covered for a year from the day we finish. If anything is not right with it, drop us a line at info@mrmastic.co.uk.

Outside joints around Arbroath
Arbroath is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
For landlords with property near Arbroath station, outside joints that have cracked can let damp into a rental, so check them between lets. Homes close to Knox's Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. Schools such as Arbroath High School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

What we can’t put right
New sealant cannot fix everything, and we will tell you before work begins. Sealant will not put right:
- Walls that need new movement joints cut into them
- Movement that is more than a sealant joint can take
- Cracking across the wall rather than at a joint
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
What the job involves on each surface
Concrete and blockwork
Big joints in concrete need careful depth control. We size the backing rod to the gap.
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible in all weathers.

What affects the cost of external mastic
There’s no set price list. What we look at:
- The size of the job
- The number of rooms or windows
- Mould in or behind the old joints
- The type of sealant required
What it costs depends on how much there is to do, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.
What we need to know
Photos by email are helpful but not essential. Please mention:
- How we’d reach the joints
- Whether it’s a home or a business
- Whether it has been sealed before
- How many joints, rooms or windows are involved
For external mastic in Arbroath, email us at info@mrmastic.co.uk. A short description of the job and where it is helps us quote, and you will get a clear quote before we start.
How to look after the new joints
A little care helps the new joints last. We recommend:
- Keep water from gutters off the wall
- Make sure movement joints aren’t pointed over
- Have failed joints looked at early
- Look over the joints every year, ideally after winter
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.
FAQs for Arbroath
Does living near the coast affect external mastic in Arbroath?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
Do you work for landlords with property near Arbroath station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
Is it OK to seal over old sealant?
No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Do the sealants smell?
There can be a smell while the sealant cures. Ventilation helps.
Can a movement joint be filled with mortar?
No. Cement or mortar can’t stretch. If it has already been filled, we can usually cut it out and reseal it.
Do you cover Arbroath?
Yes. We’re based in Crawley and work across South East England, London and Scotland.
How long will you be here?
A typical job takes a few hours to a few days, depending on the length of joint and the access. We’ll confirm how long when we quote.
How do I get a quote for external mastic in Arbroath?
Size, access and the old material all affect the cost. Ask us for a quote.
What we do, step by step
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on the building. Parking around Arbroath is rarely difficult, though older streets in the centre can be tight. For flats, mention the shared stair or door entry system.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Let us know about earlier repairs to the joints
- Let us know about parking restrictions
- Plan for the work area to be out of bounds to pets and children

DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
