How we handle window mastic in Greenbank
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. We are often asked to deal with old mastic that has gone black or come away and gaps between the frame and the inside reveal, across uPVC windows, window sills and timber windows & doors.
Tenement flats in Scotland’s cities often have windows high above the street, where failing mastic is easy to miss. Access is the first thing to plan for a job in Greenbank, and in a tenement the outside of the building may be a shared repair.
There’s a 12-month guarantee on every job, large or small.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Keeping the joints in good condition
So the new joints stay in good condition:
- Look round the frames every year or so
- Make sure the drainage slots aren’t blocked
- Do not use solvent cleaners on the joint
- Keep jet washers away from the mastic
Silicone cannot usually be painted, so mention any painting plans before any work starts. There are paintable sealants for joints that need it.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
When to call us in Greenbank
Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the brick or render around it hardly moves. If the sealant cannot stretch, it splits.
Most people get in touch when they notice one of these:
- Damp patches on the reveal after heavy rain
- Cold air getting in at the frame edge
- Rushed sealant from a window installation
- Gaps where the sill meets the wall
For landlords with property near Slateford station, renewing tired window mastic between tenants heads off draught and damp complaints.
Questions to ask before booking
- What happens if they find a problem under the old sealant
- How much experience the applicator has
- Is VAT in the price?
- How the surfaces are prepared before sealing
Questions from Greenbank
Can you help a landlord with a rental near Slateford station?
Yes, we work for landlords and letting agents. Just send an email to info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear price.
Can you do window mastic in Greenbank?
Yes, Greenbank is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.
Do you seal inside as well as outside?
Yes. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Can I add another job to the visit?
Of course. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
How long will my window job take?
Allow 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.
Can I paint over the new sealant?
Most silicone can’t be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used before we leave.
Windows and doors in Greenbank
With historic houses such as Whitefoord House (about 3 miles north-east) nearby, there’s older building stock in the area around Greenbank as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Edinburgh’s Old and New Towns 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.
For site and facilities teams at buildings such as Firrhill High School, larger buildings have plenty of frames, and the mastic around each one ages. Whitefoord House, about 3 miles north-east, is one of the historic houses in the wider area around Greenbank.

The process
You do not need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the job takes a morning for a couple of windows and a door for a typical job. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Greenbank, it helps to know the floor, the door entry arrangements and the nearest parking.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
Getting ready for the visit
- Move anything stored near the joints
- Mention any sign-in or site rules at work premises
- Mention if the joints have been sealed before
