Window Mastic in Powderhall
Mastic around window and door frames, sills and patio doors for homes and businesses in Powderhall and across Edinburgh. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- A bead that doesn’t match the frame
- Untidy mastic left by window fitters
- Cracked sealant at the sill ends
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Window mastic in Powderhall, done properly
Frames and walls don’t move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. We’re often asked to deal with untidy mastic left by window fitters and a bead that doesn’t match the frame, on uPVC windows, window sills and composite doors.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, though many have since been replaced. In Powderhall, as anywhere, the mastic between frame and wall is what stops draughts and rain getting in.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

FAQs for Powderhall
I let a flat near Edinburgh Waverley station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Who arranges sealant work on the shared parts of a tenement in Powderhall?
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 don’t.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you when we finish.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Where are you based?
We’re based in Crawley, and we cover South East England, London and all of Scotland.
How long will my window job take?
The work takes anything from an hour or two to a full day, depending on how many frames there are. Access and the amount of old mastic make the biggest difference.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Frames and glazing around Powderhall
Powderhall 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. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
For site and facilities teams at buildings such as Drummond Community High School, the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Edinburgh Waverley station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Powderhall is about 2 miles north of Edinburgh, in Edinburgh. Homes, rented property, offices and hotels in Powderhall can book us for window mastic, old or new, large or small. The work is guaranteed for a year. Powderhall is one of 175 places in Edinburgh where we work.
We work across EH6, EH7 and EH3 for window mastic and the streets around it.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Clear any debris from frame drain holes
- Do not aim a pressure washer at the joints
- Avoid harsh chemicals near the mastic
- Wash the frames with mild soapy water
Silicone can’t generally be painted, so if you’re planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
What affects the cost of window mastic
For a quick quote, just ask. What matters most is:
- How much old sealant there is and how hard it is to remove
- Which sealant suits the joint
- The number and length of the joints
- Mould in or behind the old joints
What you pay reflects the work, not guesswork. That is why we ask about the job first.
Helping us quote
There’s no need for technical detail. Just tell us:
- Any previous sealing or DIY work
- What’s wrong with the joints now
- Where the job is, and your postcode
- The type of property
If you are in Powderhall and need window mastic, send an email to info@mrmastic.co.uk. Tell us what the problem is and where, and we’ll agree the price before any work begins.
What we are called out for in Powderhall
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.
The most common problems we see are:
- Mastic that has split away from the wall
- Gaps where the sill meets the wall
- Draughts coming in around windows and doors
- Rain getting in at the frame or under the sill
For an older house near a landmark such as St Philip's Church And Hall, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
