Claverhouse External Mastic
Sealing brickwork movement joints, render, cladding and façade joints for homeowners, landlords and businesses in Claverhouse. Fully insured, ARBOMaster approved and guaranteed for a year.
- Failed sealant between panels on a façade
- Joints with sealant missing in places
- Joints where the bead has come unstuck
When to call us in Claverhouse
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
The most common problems we see are:
- Joints where the bead has come unstuck
- Movement joints filled with mortar instead of sealant
- Hard, crazed mastic that has stopped moving
- Panel joints letting water in
If you let a flat or house near Dundee station, split movement joints are easy to miss on a rental until damp shows inside.

How we handle external mastic in Claverhouse
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the line blends in. We work on façade panels, copings & trims and concrete & block, and the jobs we see most are weeds or debris growing in open joints and failed sealant between panels on a façade.
On a four-storey tenement, gutter joints are a long way from the street, so a leaking joint can run down the stone for months before anyone notices. In Claverhouse, access needs planning, and work on shared parts may need the other owners’ agreement.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What else we do in Claverhouse
Walls and rooflines in Claverhouse
Claverhouse is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Dundee sits on the north bank of the Tay, and much of its older housing is sandstone tenements.
If you live in an older home near Mains Parish Church, an extension built onto an older house moves differently, and the joint between them takes the strain. If you look after a building such as Scottish School of Contemporary Dance, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

How it works
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours for a handful of joints, longer for a whole elevation. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Claverhouse, it helps to know the floor, the door entry arrangements and the nearest parking.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Tell us if parking is tricky
- Mention if the joints have been sealed before
- For business premises, tell us about site rules or sign-in

Why deal with it now?
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render around the joint, so the damage spreads beyond the joint. In a tenement flat in Claverhouse, a failed seal is rarely just your problem: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.
Why book with us

How we quote for external mastic
Every job gets its own quote. This is what makes a difference:
- How many rooms, windows or areas are involved
- Working hours on commercial sites
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
What you pay reflects the work, not guesswork. That’s why we ask about the job first and send you a clear quote before any work starts.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Whether it’s a home or a business
- Any previous sealing or DIY work
- The problem you’ve noticed
- How many joints, rooms or windows are involved
For external mastic in Claverhouse, send an email to info@mrmastic.co.uk. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.
When something else is needed
We will not take on work that won’t last, so here’s what sealant can’t put right:
- Loose or hollow render, which needs re-rendering
- Subsidence or other structural problems
- Cracking across the wall rather than at a joint
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before you book.
Where we work in Claverhouse
- Render & cladding joints
- Brickwork movement joints
- Concrete & block
- Copings & trims
- Joints between brick and frames
- Façade panels
Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Claverhouse: your questions answered
Does living near the coast affect external mastic in Claverhouse?
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. It’s worth checking the walls that face the sea first.
I let a flat near Dundee station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear price.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
Will the new joint stand out?
The sealant colour is picked to suit the wall, so the joint sits quietly in the wall. Exterior sealants come in a good range of colours.
How often do external joints need resealing?
That varies with the weather the wall faces, how much it moves and the sealant used. Sealant is a maintenance item, so check the joints once a year and reseal when it splits.
Do you use backing rod?
That is backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Do you work at height?
That depends on the building and the joints. Where joints can be reached safely, we’ll do them. Tell us about the building and we’ll confirm what access is needed.
Aftercare tips
So the new joints stay in good condition:
- Keep movement joints as flexible joints, not mortar
- Fix overflowing gutters above sealed joints
- Tell anyone working on the walls about the movement joints
- Check the sealant is paintable before painting near it
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.
