FAQs for Altens
Does the coastal weather in Altens affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
How is work on the outside of a tenement in Altens generally arranged?
Shared parts of a tenement, such as the roof and outside walls, are generally repaired with the agreement of the owners, often through a property factor. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Windows often belong to the individual flat, but it’s worth checking your deeds.
Is it possible to redo the silicone on a shower screen?
Yes, we do these often. We use anti-fungal silicone made for wet areas.
How long before the joint can be used?
That depends on the sealant used, so please follow the time we give you.
Where is Mr Mastic based?
We are based in Crawley, and we work across South East England, London and Scotland.
Do you come to Altens?
Yes, we do. Altens is part of the area we cover.
What sealant do you use on glazing?
A neutral-cure glazing silicone suited to glass and the frame. In bathrooms, we use anti-fungal silicone.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
How we handle glazing silicone in Altens
Cracked, stained or lifting silicone on glass looks poor and can leak. We remove it without scratching the glass or frame before the new bead goes in. Common call-outs are for glazing silicone that has cracked or come away and water getting into a conservatory at the joints, on conservatory frames, glass-to-frame joints and rooflights.
Scotland’s cities are full of stone-built tenements and terraces, in sandstone or granite. Stone needs a sealant that suits it, so acetoxy silicones, which can attack some stone, are best avoided.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

What we can’t put right
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- A broken pane or roof panel
- Structural problems with a conservatory roof
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly.
Joints and surfaces we work on
- Glass balustrade bases
- Glass-to-glass joints
- Shower screens
- Glass-to-frame joints
- Conservatory frames
- Rooflights
Different surfaces, different methods
Conservatory frames
Frame joints face sun and rain all year. Renewed sealant keeps water out.
Glass-to-frame joints
Glass-to-frame joints need a sealant that bonds to both. We choose a product that suits both.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How the visit works
The work is kept neat and contained to the joints we’re treating. Expect the work to take a few hours, depending on how many joints need doing, and we explain the cure time before we leave. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In Altens, it helps to know the floor, the door entry arrangements and the nearest parking.
- First, we trace the leak and check it’s coming through a sealant joint.
- The old sealant is removed from the glass and frame without scratching them.
- 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 look over every joint and, where we can, test it with water.
Before we arrive
- Move anything stored near the joints
- Tell us about any water getting in
- Let us know about stairs, lifts or work at height

Advice
Aftercare tips
Looking after new joints is easy:
- Keep scrapers and blades away from the silicone
- Keep air moving in the conservatory
- Clean glass with a mild cleaner and a soft cloth
- Check the gutters above the glazing for debris
On shower screens, wipe or squeegee after use and keep the room ventilated. That slows mould growth on the bead.
Drips or damp near a glazing joint shouldn’t be ignored. It may be sealant, or something else, and we will tell you which.
Altens homes and the weather
Altens is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on glazing joints and frame seals, especially on the side facing the sea. With historic houses such as Friendville (about 2.4 miles north-west) nearby, there’s older building stock in the area around Altens as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
In the older streets around Nigg Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as Lochside Academy, larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Aberdeen station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Why it’s worth doing now in Altens
Silicone around glazing needs the right product. A general-purpose tube may not bond well or may react with the frame so we choose a glazing silicone instead. Private landlords in Altens 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.
