Do you need window mastic in Piershill?
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
People normally contact us after spotting something like this:
- Gaps between the frame and the inside reveal
- Mastic that is falling out in pieces
- Untidy mastic left by window fitters
- Damp patches on the reveal after heavy rain
Schools such as Portobello High School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before you book

- Is VAT in the price?

Window mastic in Piershill
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that cannot flex, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. Common call-outs are for gaps left after new windows were fitted and sealant in the wrong colour for the frame, on uPVC windows, composite doors and window sills.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, though many have since been replaced. In Piershill, as anywhere, the mastic between frame and wall is what stops draughts and rain getting in.
You get a one-year guarantee, the same in Piershill as everywhere else we work.

How the visit works
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes anything from an hour or two to a full day, depending on how many frames there are for a typical job. In a city area like Piershill, parking may be by permit or pay-and-display, so tell us what’s nearby. If you are in a flat, let us know how we get in at the street door.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Mention any parking rules near the property
- Tell us about any previous sealing or DIY attempts
- Move anything stored near the joints

Related advice
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Why act early in Piershill
If you are painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished. In a Scottish city tenement, failed sealant affects more than one flat: 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.

Frames and glazing around Piershill
Piershill is within about 2 miles of 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. The Old and New Towns of Edinburgh are a UNESCO World Heritage Site, with sash windows throughout the Georgian New Town. 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.
Rented homes near Edinburgh Waverley station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. If you live in an older home near Willowbrae Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What sealant work can’t fix

- A sash or casement that will not close properly

FAQs for Piershill
Is window mastic in a coastal place like Piershill any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
How do repairs to the shared parts of a tenement in Piershill get organised?
Shared parts of a tenement, such as the roof and outside walls, are generally repaired with the agreement of the owners, often through a property factor. 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 it OK to seal over old sealant?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Is the work guaranteed?
Yes. Every job comes with our one-year guarantee, and we’re ARBOMaster approved applicators.
Will resealing my frames help with draughts?
If the draught is coming in around the frame, yes. If it’s through the window’s own seals or a hinge, that is a different fix, and we will say so.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is normally more efficient.
Do you have insurance?
Yes. Mr Mastic is fully insured.
How long should I leave it?
Cure times vary by product and the temperature. Before we leave, we will tell you the cure time.
How the job changes by surface
Window sills
Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. We seal those with a sealant suited to masonry.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We will tell you which suits your home.
