How we handle external mastic in Niddrie
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two where mortar or filler would crack. We work on façade panels, joints between brick and frames and copings & trims, and common reasons people get in touch are old sealant gone brittle and cracked and joints with sealant missing in places.
In a Scottish city tenement, the roof, gutters and outside walls are shared by all the flats. For a tenement in Niddrie, repairs to shared parts are generally agreed between the owners, often through a property factor.
All our work comes with a one-year guarantee, wherever you are in Edinburgh.

Niddrie: your questions answered
Who arranges sealant work on the shared parts of a tenement in Niddrie?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds do not, and we can quote for the factor or the owners directly.
Can you help a landlord with a rental near Brunstane station?
Yes. We work for landlords and agents as well as householders. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
Are you insured?
Yes. We are fully insured for every job we do.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
How do I get a quote for external mastic in Niddrie?
Size, access and the old material all affect the cost. Ask us for a quote.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
Why act early in Niddrie
Sealing over the top of old mastic doesn’t hold for long. The new layer can’t bond properly to old, weathered material, so we always take the old sealant out. For landlords in Niddrie, damp and leaks can be a Repairing Standard issue, so failed sealant is best replaced before it becomes a complaint.
Doing several joints on one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Look over the joints every year, ideally after winter
- Check the sealant is paintable before painting near it
- Keep movement joints as flexible joints, not mortar
- Avoid pressure-washing directly into sealant joints
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.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
Surface by surface
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. Where one has been mortared, we cut it out and reseal it with sealant.
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.

Common problems we fix in Niddrie
Buildings move more than people expect. 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.
Most people get in touch when they notice something like this:
- Damp patches traced to an open external joint
- Joints with sealant missing in places
- Rigid filler in a joint that should flex
- Hard, crazed mastic that has stopped moving
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.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
What external mastic looks like in Niddrie
Niddrie is close to 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. The Old and New Towns of Edinburgh are a UNESCO World Heritage Site, and the Georgian New Town is known for its sash windows. If a home is listed or in a conservation area, it’s worth checking with the council before changing the look of windows or walls.
Managing a site like Castlebrae Community High School? Then larger buildings have long runs of movement joint that eventually need resealing. Whitefoord House, about 2.8 miles north-west, is one of the historic houses in the wider area around Niddrie.

How it works
You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes anything from a few hours to several days, depending on the building for a typical job. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Niddrie, it helps to know the floor, the door entry arrangements and the nearest parking.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Mention if the joints have been sealed before
- Try not to wet indoor joints just before the visit
- Let us know about parking restrictions
