How we handle external mastic in Niddrie Mains
On houses, flats and commercial buildings across Niddrie Mains, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. We work on copings & trims, concrete & block and façade panels, and people most often call us about plants rooting in failed movement 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 Niddrie Mains, access needs planning, and work on shared parts may need the other owners’ agreement.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Walls and rooflines in Niddrie Mains
Niddrie Mains 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. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Historic houses like Whitefoord House (about 2.4 miles north-west) are a reminder that the area around Niddrie Mains has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Rented homes near Brunstane station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. Schools such as Castlebrae Community High School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Whitefoord House, about 2.4 miles north-west, is one of the historic houses in the wider area around Niddrie Mains, and older homes nearby need a sealant that suits their walls.

The process
The work is kept neat and contained to the area we are working on, so you can carry on as normal. The job generally takes a few hours for a handful of joints, longer for a whole elevation, and we tell you how long to leave it before we go. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Niddrie Mains, it helps to know the floor, the door entry arrangements and the nearest parking.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Let us know about parking restrictions
- On commercial sites, let us know about site rules
- Let us know about stairs, lifts or work at height

How we quote for external mastic
We don’t publish a price list, because jobs vary so much. The quote depends on:
- The old material and how stubborn it is
- Access and height
- Which sealant suits the joint
- Any mould that needs treating
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Asking for a quote
When you contact us, these details help:
- Photos by email, if that’s easy
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking
- Roughly how big the job is
Asking for a quote is easy: tell us what needs doing and where and its rough size. A few pictures by email make the job easier to understand, and we’ll take it from there.
Honest limits
Before you book, it’s worth knowing the limits too:

- Loose or hollow render, which needs re-rendering
- Adding movement joints to masonry that has none

Niddrie Mains: your questions answered
Does the coastal weather in Niddrie Mains affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
How is work on the outside of a tenement in Niddrie Mains generally arranged?
Shared parts of a tenement, such as the roof and outside walls, are normally repaired with the agreement of the owners, often through a property factor. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Windows often belong to the individual flat, but it’s worth checking your deeds.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme.
I’m a tenant. Can you help?
Yes. Check with your landlord; we can send the quote to them too.
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.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Do the sealants smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Do you guarantee your work?
Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.
How to look after the new joints
Looking after new joints is easy:
- Keep soil, plants and ivy away from the joints
- Act on the first splits you see
- Keep movement joints as flexible joints, not mortar
- Ask before painting over external sealant
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
A joint that has stopped moving pushes the movement elsewhere, normally as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
Leave it or put it right?
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. Private landlords in Niddrie Mains must meet the Repairing Standard, and damp or leaks can fall short of it, so failed sealant is best replaced before it becomes a complaint.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

Work for landlords, hotels and businesses
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Hotels need rooms back in use, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
Should I try it myself first?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
