What external mastic looks like in Joppa
Joppa is within about 1 mile of 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. With historic houses such as Whitefoord House (about 3.2 miles west) nearby, there’s older building stock in the area around Joppa as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
For site and facilities teams at buildings such as Portobello High School, its movement joints, gutters and trims need looking after like any other building’s. If you let a flat or house near Brunstane station, outside joints that have cracked can let damp into a rental, so check them between lets. For an older house near a landmark such as St Philip's Parish Church, an extension built onto an older house moves differently, and the joint between them takes the strain.
Joppa is about 1 mile east of South Portobello, in Edinburgh. Homes, rented property, offices and hotels in Joppa can book us for external mastic, old or new, large or small.

About our external mastic in Joppa
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we will confirm what’s needed to reach them safely. We work on brickwork movement joints, façade panels and concrete & block, and the jobs we see most are hard, crazed mastic that has stopped moving and damp patches traced to an open external joint.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. Newer houses need their movement joints and roofline trims kept sound.
We stand behind the work with a one-year guarantee.

Leave it or put it right?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render near the open joint, so the damage spreads beyond the joint. In an older home around Joppa, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please drop us a line at info@mrmastic.co.uk and we will talk you through it.

Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Joppa: your questions answered
Does the coastal weather in Joppa affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Can you help a landlord with a rental near Brunstane station?
Yes. We work for landlords and letting agents as well as homeowners. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
Why do you put foam in the joint first?
Backing rod goes into deeper joints as a matter of course. It sets the sealant depth and prevents three-sided bonding, so the joint can move.
Where do you work from?
Mr Mastic is based in Crawley. We cover Joppa and the rest of Edinburgh.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
How often do external joints need resealing?
It depends on the exposure, the movement and the product. Treat it as a maintenance item and look at it yearly.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient.
Surface by surface
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it and keep the sealant to the right depth.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so its sealant has to stay flexible.
What we do, step by step
We keep the work tidy and contained to the joints we’re treating. The job usually takes a few hours to a few days, depending on the length of joint and the access. Outdoor work around Joppa depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- 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.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Clear items away from the joints we’re working on
- Let us know about stairs, lifts or work at height
- Keep children and pets away from the work area

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Do not let climbing plants root in the sealant
- Ask before painting over external sealant
- Look over the joints every year, ideally after winter
- Have failed joints looked at early
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
