Surface by surface
Glass balustrade bases
The base of a glass balustrade is usually sealed. When it fails, water can sit in the channel.
Glass-to-glass joints
Silicone joins glass panels in many frameless designs. We renew it with a clear or matching glazing silicone.
Glazing silicone in Comely Bank, done properly
Glass and frames expand and contract differently, and the silicone between them takes the strain. When it cracks or lets go, water gets in. We replace it with a glazing silicone that suits the glass and frame. We work on glass-to-glass joints, glass-to-frame joints and shower screens, and people most often call us about black or yellowed silicone on glass joints and glazing silicone that has cracked or come away.
Sash and case windows are a feature of older tenements in all four Scottish cities, though many have since been replaced. In Comely Bank, as anywhere, the mastic between frame and wall is what stops draughts and rain getting in.
Your job is guaranteed for a year, as with all our work.

Comely Bank: your questions answered
Do you work for landlords with property near Haymarket station?
Yes, we work for letting agents and landlords. You can send an email to info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before we start.
Does living near the coast affect glazing silicone in Comely Bank?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
When is the sealant fully cured?
Cure times vary by product and the conditions. Before we leave, we’ll tell you the cure time.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
What sealant do you use on glazing?
A neutral-cure glazing silicone that suits the glass and frame. In bathrooms, we use anti-fungal silicone.
Can I choose the sealant colour?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
Can a conservatory leak be sealed?
Yes, when the leak is a failed sealant joint. If it’s a broken panel, failed unit or roof problem, we’ll tell you.
Do you have insurance?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
The process
Before we leave, we go over the finished joints with you. The work normally takes a few hours for most jobs, depending on the size of the job. For a tenement in Comely Bank, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. Tell us which applies when you book.
- First, we trace the leak and check it’s coming through a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- New glazing silicone goes in and is tooled to a neat finish.
- We check the joints and, where safe, run water over them.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive
- Tell us if parking is tricky
Ask for a quote
Getting a quote is simple: let us know what needs doing and where and its rough size. A few photos by email make the job easier to understand, and we will take it from there.

Windows and doors in Comely Bank
Comely Bank is close to 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 glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Managing a site like Broughton High School? Then its window and door frames need their mastic kept sound, just like a home’s. In the older streets around Dean Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Do you need glazing silicone in Comely Bank?
UV light ages silicone, especially on conservatory roofs. It goes brittle, cracks and stops sticking on the glass.
The most common problems we see are:
- Silicone pulling away from the glass
- Water tracking down the inner face of the glass
- Failed sealant around rooflight glass
- Cracked silicone between glass panels
For landlords with property near Haymarket station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Run a squeegee over the glass when you’re done
- Open vents or windows to let moisture out
- Do not use a blade near the sealant
- Act on drips or damp patches early
Don’t use blades or scrapers near the bead when you clean. Stick to a soft cloth.
Drips or damp near a glazing joint shouldn’t be ignored. It may be sealant, or something else and we will find out which.
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Landlord and commercial work in Comely Bank
We also work for property managers and facilities teams in Comely Bank and across Edinburgh. We can quote a run of properties together, and we’re fully insured for the work.
Hotels need rooms back in use, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
What happens if it’s left?
Leaks get worse, not better. Left, water can mark floors, damage plaster and rot timber so early action saves a bigger repair. Private landlords in Comely Bank 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.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.
