Window & door mastic in St Leonard's, Edinburgh
We cover St Leonard's for mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Cold air getting in at the frame edge
- Old mastic that has gone black or come away
- Untidy mastic left by window fitters
Keeping the joints in good condition
After the cure time, these simple habits help:
- Keep solvents and bleach off the sealant
- Keep paint and stain on wooden frames in good order
- Do not paint over the silicone
- Avoid blasting the frames with a pressure washer
Try not to touch the new joint while it cures, for as long as we advise. Do not point a pressure washer at the joints.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
About our window mastic in St Leonard's
Colour matters on a frame. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. We work on timber windows & doors, uPVC windows and patio & French doors, and the jobs we see most are water coming in at the bottom corners of a door and cracked internal joints between frame and plaster.
In a Scottish city, many flats have windows two, three or four floors up, where failing mastic is easy to miss. Access is the first thing to plan for a job in St Leonard's.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What window mastic looks like in St Leonard's
St Leonard's is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
Rented homes near Edinburgh Waverley station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Historic houses such as Whitefoord House, about 0.9 miles north, show how far back building around St Leonard's goes.

In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Should I try it myself first?
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.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Questions from St Leonard's
Is window mastic in a coastal place like St Leonard's any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
I let a flat near Edinburgh Waverley station. Can you help?
Yes, rental work is part of what we do. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
What should I tell you?
Tell us what needs doing and where. We’ll ask anything else we need to know.
Do you seal inside as well as outside?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We do one or both.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
When to call us in St Leonard's
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
Look out for these signs:
- Draughts coming in around windows and doors
- Damp patches on the reveal after heavy rain
- Untidy mastic left by window fitters
- Mastic that has split away from the wall
Schools such as St Trinnean's School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

What we do, step by step
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work 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. For a job in St Leonard's, tell us the floor, how the door entry system works and where we can park nearby.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any water getting in
- Mention any tricky access
