Greendykes Window Mastic
Window and door frames in Greendykes need attention? We cut out the old, prepare the joints and apply the right sealant.
- Cracked or shrunken mastic around the frame
- A bead that does not match the frame
- Old mastic that has gone black or come away
Signs you need window mastic in Greendykes
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the brick or render around it hardly moves. A sealant that can’t keep up eventually tears.
The problems people generally mention when they call include:
- White mastic on grey or black frames
- Draughts coming in around windows and doors
- Damp patches on the reveal after heavy rain
- Black, perished sealant on frames
For landlords with property near Brunstane station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Window mastic for homes and businesses in Greendykes
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you have damp patches on the reveal after heavy rain and untidy mastic left by window fitters, we can help.
Greendykes is in one of Scotland’s four big cities, where many older buildings are sandstone or granite. Natural stone around older windows needs a sealant that won’t mark or attack it, so acetoxy silicones, which can attack some stone, are best avoided.
Big or small, you get the same one-year guarantee in Greendykes and across Edinburgh.

What else we do in Greendykes
Landlords, agents and businesses in Greendykes
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Why deal with it now?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. In a tenement flat in Greendykes, a failed seal is rarely just your problem: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and agree the price before starting.
Why choose Mr Mastic in Greendykes
- Arbo and Everbuild products
- Homes, businesses and hotels
- A choice of colours where the product allows
- You choose the colour before work begins

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Clean frames with a soft cloth and soapy water
- Paint up to the joint, not over it
- Keep paint and stain on wooden frames in good order
- Check the mastic once a year
Most silicone sealants won’t take paint, so mention any painting plans before we start. We can use a paintable sealant where that matters.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and a cold room gets colder. Resealing closes it.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
How it works
We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take most of a day for a typical house, less for a few frames. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. For a job in Greendykes, tell us the floor, how the door entry system works and where we can park nearby.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- 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
- Try not to wet indoor joints just before the visit
- Clear the area around the work
- Keep children and pets away from the work area

Greendykes: your questions answered
Who arranges sealant work on the shared parts of a tenement in Greendykes?
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.
Do you work for landlords with property near Brunstane station?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear quote.
Can new sealant go over the old?
No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Can resealing stop a draught around my window?
Yes, where the draught is at the frame edge. We find where the air is coming from before we reseal.
Can you match the sealant to my frames?
Yes, we choose a colour to suit the frame. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Are you fully insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
How the job changes by surface
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match keeps the clean look.
Frames and glazing around Greendykes
Greendykes 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. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Under the Tenements (Scotland) Act 2004, shared parts of a tenement, such as the roof and outside walls, are looked after by the owners together, often through a property factor. Who owns the windows depends on the title deeds.
If you live in an older home near Robin Chapel, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you look after a building such as Castlebrae Community High School, the mastic around its windows and doors needs looking after like any other building’s.
