How the job changes by surface
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. The old joint is removed and a sealant that bonds to both sides goes in.
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod.
External mastic in Powderhall
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. Typical jobs include water getting into walls through failed joints and panel joints letting water in, across concrete & block, render & cladding joints and brickwork movement joints.
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 Powderhall, access needs planning, and work on shared parts may need the other owners’ agreement.
The work is covered for a year after we finish. If anything is not right with it, drop us a line at info@mrmastic.co.uk.

Powderhall buildings and the weather
Powderhall is within about 1 mile 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. Historic houses like Whitefoord House (about 1.2 miles south-east) are a reminder that the area around Powderhall has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Managing a site like Drummond Community High School? Then larger buildings have long runs of movement joint that eventually need resealing. Rented homes near Edinburgh Waverley station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

DIY sealant or a professional job?
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.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
When it is not the sealant
To be straight with you, some problems need a different trade:
- Movement that’s more than a sealant joint can take
- Failed render or damaged cladding panels
- Walls that need new movement joints cut into them
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before you book.
What we seal
- Joints between brick and frames
- Render & cladding joints
- Façade panels
- Brickwork movement joints
- Concrete & block
- Copings & trims

Common questions in Powderhall
Can you help a landlord with a rental near Edinburgh Waverley station?
Yes, landlords and agents are among the people we work for. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear price.
Is external mastic in a coastal place like Powderhall any different?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
What information do you need?
A short description and the location. If we need more, we will ask.
Where do you work from?
Our base is in Crawley, and we work across South East England, London and Scotland.
Why do you put foam in the joint first?
We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back, so the joint can move.

Common problems we fix in Powderhall
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
The most common problems we see are:
- Damp patches traced to an open external joint
- Failed sealant between panels on a façade
- Joints with sealant missing in places
- Joints where the bead has come unstuck
For an older house near a landmark such as St Philip's Church And Hall, the joints between older walls, newer extensions and the roofline need a sealant that can move.

What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours to a few days, depending on the length of joint and the access and we leave things clean and tidy. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Powderhall, it helps to know the floor, the door entry arrangements and the nearest parking.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- 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.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Tell us if parking is tricky
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children
