Window mastic in Niddrie, done properly
From a single sill to a whole house of windows, the work is priced before anything is done. Just send an email to info@mrmastic.co.uk and tell us how many frames there are and how they’re reached. We work on uPVC windows, patio & French doors and composite doors, and common reasons people get in touch are damp patches on the reveal after heavy rain and cracked or shrunken mastic around the frame.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, and plenty still have them. Whether you’re in a tenement flat or a house in Niddrie, the joint between frame and wall is what keeps the weather out.
Big or small, it’s backed by our 12-month guarantee.

Different surfaces, different methods
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain cannot run into the wall.
What affects the cost of window mastic
The price is agreed before any work begins. It’s based on:
- The old material and how stubborn it is
- The size of the job
- Any mould that needs treating
- How many rooms, windows or areas are involved
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, send an email to info@mrmastic.co.uk for an honest opinion and a quote.
Asking for a quote
To help us quote quickly, let us know:
- How many joints, rooms or windows are involved
- Pictures of the joints, sent by email
- Where the job is, and your postcode
- If someone has resealed it before
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, send an email to info@mrmastic.co.uk.
When to call us in Niddrie
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, while a joint packed solid can’t stretch. Backing rod sets the right depth.
Common reasons people contact us are:
- Untidy mastic left by window fitters
- Draughts coming in around windows and doors
- Cracked internal joints between frame and plaster
- Mastic that is falling out in pieces
Whitefoord House, about 2.8 miles north-west, is one of the historic houses in the wider area around Niddrie.

The process
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. It normally takes anything from an hour or two to a full day, depending on how many frames there are. 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 check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints
- For indoor joints, keep the area dry beforehand if you can

Advice
Common questions in Niddrie
Does living near the coast affect window mastic in Niddrie?
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. Walls facing the sea are usually the first to need attention.
Who arranges sealant work on the shared parts of a tenement in Niddrie?
The owners of the flats usually agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. The Tenements (Scotland) Act 2004 sets out how that works where the title deeds don’t. Windows often belong to the individual flat, but it’s worth checking your deeds.
Is there any odour?
Sometimes, a little. It fades as the sealant cures.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Can you match the sealant to my frames?
Usually, yes. Tell us the frame colour when you get in touch and we’ll use the nearest match.
Can you do the inside joint as well?
Yes, we do both. Inside, the joint between frame and plaster is sealed neatly.
How many windows can you do in a day?
A handful of frames is a short visit, while a whole house takes longer. We confirm the timing with your quote.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
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: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Why it’s worth doing now in Niddrie
Getting a straight, even bead on an outside frame takes practice, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. In a tenement flat in Niddrie, 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.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Window mastic in Niddrie: local notes
Niddrie 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 the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Historic houses like Whitefoord House (about 2.8 miles north-west) are a reminder that the area around Niddrie has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For landlords with property near Brunstane station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Managing a site like Castlebrae Community High School? Then the mastic around its windows and doors needs looking after like any other building’s.

When it is not the sealant
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Draughts through the window seals rather than the frame
- A failed sealed unit that has misted up
- Penetrating damp from a failed cavity tray or render
