About our external mastic in Bladnoch
Low-level joints can normally be done from the ground. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. We work on joints between brick and frames, façade panels and render & cladding joints, and the jobs we see most are panel joints letting water in and sealant that has lost its bond to the brick or render.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.
The work is covered for a year after we finish. If anything isn’t right with it, send an email to info@mrmastic.co.uk.

Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What happens on the day
The work is kept neat and contained to the area we’re working on. Expect the work to take a few hours to a few days, depending on the length of joint and the access. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- 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.
- 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.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Keep children and pets away from the work area
- For indoor joints, keep the area dry beforehand if you can

Landlords, agents and businesses in Bladnoch
In hotels, rooms out of use cost money, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

Copings and trims
A failed coping joint lets water into the top of the wall. Sealing them early saves the wall below.
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant.
Common questions in Bladnoch
Will you come out to Bladnoch?
Yes, we do. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Does living near the coast affect external mastic in Bladnoch?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
What does external mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we will talk you through it.
How long before the joint can be used?
That depends on the sealant used, so follow the cure time we give you when we finish.
Do you work for letting agents?
Yes, regularly. We can quote for several properties at once, and between tenancies is a good time for the work.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
When will the joints need doing again?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away and have them redone then.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Quotes for external mastic in Bladnoch
Jobs vary more than people expect. The main factors:
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
- Whether the work is at height
- Which sealant suits the joint
Combining jobs into one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
Asking for a quote
What to tell us when you ask for a quote:
- Pictures of the joints, sent by email
- If someone has resealed it before
- What’s wrong with the joints now
- Whether it’s a home or a business
For a quick quote, get us on the phone, or email us if that is easier. Tell us about the joints that need doing and we will explain what’s involved.
What we can’t put right
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- Walls that need new movement joints cut into them
- Movement that’s more than a sealant joint can take
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If you’re not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer.

Walls and rooflines in Bladnoch
Bladnoch is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. 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.
If you live in an older home near Sacred Heart Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

What we’re called out for in Bladnoch
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.
The most common problems we see are:
- Brick movement joints where the sealant has split
- Water getting into walls through failed joints
- Weeds or debris growing in open joints
- Movement joints filled with mortar instead of sealant
Around Bladnoch, as everywhere, external mastic is only as good as the preparation behind it.
