Window mastic in Fernieside, done properly
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that cannot move properly, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. Typical jobs include white mastic on grey or black frames and untidy mastic left by window fitters, across patio & French doors, uPVC windows and composite 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 Fernieside.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

How the job changes by surface
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that without cracking.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
How to look after the new joints
A little care helps the new joints last. Our advice:
- Wash the frames with mild soapy water
- Don’t paint over the silicone
- Avoid harsh chemicals near the mastic
- Avoid blasting the frames with a pressure washer
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
FAQs for Fernieside
Does the coastal weather in Fernieside affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
Who arranges sealant work on the shared parts of a tenement in Fernieside?
The owners of the flats usually agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. The Tenements (Scotland) Act 2004 sets out how that works where the title deeds don’t. Your title deeds will say who owns the windows.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
When is the sealant fully cured?
It depends on the product. Before we leave, we’ll tell you the cure time.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.

When to call us in Fernieside
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, so it comes away long before its time.
These are the problems we are asked about most:
- Cracked or shrunken mastic around the frame
- Gaps left after new windows were fitted
- Whistling draughts around closed windows
- Rain getting in at the frame or under the sill
If you look after a building such as Liberton High School, its window and door frames need their mastic kept sound, just like a home’s.

What happens if it’s left?
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. Private landlords in Fernieside must meet the Repairing Standard, and damp or leaks can fall short of it, so it’s worth fixing failed sealant before a tenant reports it.
Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

What happens on the day
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes 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. In Fernieside, it helps to know the floor, the door entry arrangements and the nearest parking.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky

DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Window mastic in Fernieside: local notes
Fernieside 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 is hard on the mastic around window and door frames, especially on the side facing the sea. Edinburgh’s Old and New Towns are a UNESCO World Heritage Site, with sash windows throughout the Georgian New Town. For listed homes and conservation areas, check with the council before changing how windows or walls look.
In the older streets around Liberton Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Shawfair station, renewing tired window mastic between tenants heads off draught and damp complaints.
