Window & door mastic in North Leith, Edinburgh
We cover North Leith for mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly.
- Cracked sealant at the sill ends
- A bead that does not match the frame
- Rushed sealant from a window installation
About our window mastic in North Leith
There are two joints on most windows. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. Common call-outs are for gaps where the sill meets the wall and draughts coming in around windows and doors, on timber windows & doors, composite doors and aluminium frames.
Sash and case windows are a feature of older tenements in all four Scottish cities, though many have since been replaced. Whether you’re in a tenement flat or a house in North Leith, the joint between frame and wall is what keeps the weather out.
The work is covered for a year after we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

Landlord and commercial work in North Leith
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.

Aftercare tips
After the cure time, these simple habits help:
- Keep solvents and bleach off the sealant
- Keep timber frames painted
- Avoid blasting the frames with a pressure washer
- Wipe condensation off the frames
Silicone cannot usually be painted, so mention any painting plans before we start. There are paintable sealants for joints that need it.
Leaks usually show up in wet, windy weather, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Leave it or put it right?
Running fresh sealant over the old joint is tempting, but new sealant cannot bond to old, crumbling mastic. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. In a Scottish city tenement, failed sealant affects more than one flat: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

North Leith homes and the weather
North Leith is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around window and door frames, especially on the side facing the sea. 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 cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. For site and facilities teams at buildings such as Leith School of Art, larger buildings have plenty of frames, and the mastic around each one ages.

- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- 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.
- We clear up and check every joint is fully closed.

Advice
Your questions about window mastic in North Leith
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.
Does the coastal weather in North Leith affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Do you come to North Leith?
Yes. We work in North Leith and the rest of Edinburgh. For a quote, email us at info@mrmastic.co.uk.
Is the work guaranteed?
Yes, with our one-year guarantee. Keeping drainage clear and checking the joints yearly helps them last.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures.
Are you fully insured?
Yes, we’re fully insured.
Signs you need window mastic in North Leith
On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
Most people get in touch when they notice something like this:
- Cracked internal joints between frame and plaster
- Untidy mastic left by window fitters
- Whistling draughts around closed windows
- Water coming in at the bottom corners of a door
Homes close to Leith Baptist Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
