External mastic in Blackburn
A movement joint is only as good as its depth. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. If you have weathered mastic that no longer stretches and cracked joints where brick meets render or frames, we can put it right, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Blackburn depends on the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Leave it or put it right?
Resealing a run of joints in one go is normally better than patching one at a time. They’ve weathered the same way, and access only has to be arranged once. In an older home around Blackburn, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, email us at info@mrmastic.co.uk and we will give you an honest view and a quote.
Why us?
- 12-month guarantee on every job
- Quality sealants from Arbo and Everbuild
- Any old sealant cut out fully, not covered over
- Fully insured

Walls and rooflines in Blackburn
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Aberdeen is known as the Granite City, and sealing against granite needs clean, sound edges and a sealant that suits stone.
For landlords with property near Kintore station, outside joints that have cracked can let damp into a rental, so check them between lets.

Questions from Blackburn
Is Blackburn within the area you cover?
Yes. Blackburn is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Is Blackburn in your area for external mastic?
Yes. We work across all of Scotland, and Blackburn is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing, and we will give you a clear price.
Why do you put foam in the joint first?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding, so the joint can move.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
How do I get a quote for external mastic in Blackburn?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You will get a clear quote before we start.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.
Can you do several jobs on one visit?
Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Work for landlords, hotels and businesses
We also work for property managers and facilities teams in Blackburn and across Aberdeen. Several sites can be quoted together, and we’re fully insured.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
How it works
The work is kept neat and contained to the area we’re working on, so you can carry on as normal. The job normally takes anything from a few hours to several days, depending on the building. Somewhere like Blackburn may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Mention any sign-in or site rules at work premises
- Plan for the work area to be out of bounds to pets and children

Advice
What we’re called out for in Blackburn
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it cannot stretch and tears as soon as the joint widens.
Most people get in touch after spotting one of these:
- Hard, crazed mastic that has stopped moving
- Sealant that has lost its bond to the brick or render
- Damp patches traced to an open external joint
- Rigid filler in a joint that should flex
In and around Blackburn, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
