DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
How we handle glazing silicone in Kalliness
Our work covers conservatory joints, rooflights and glass panels plus shower screens and the bases of glass balustrades. The old sealant comes out, the joint is cleaned and new silicone goes in. We are often asked to deal with leaks where conservatory glass meets the frame and leaks from the base of a shower screen, across rooflights, conservatory frames and glass balustrade bases.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
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.

Honest limits
To be straight with you, some problems need a different trade:
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- Glass that needs replacing
- Water coming through the roof rather than a sealant joint
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think.

How we quote for glazing silicone
We do not publish a price list. What we look at:
- Whether there’s mould to deal with
- Access and height
- The type of sealant required
- How much old sealant there is and how hard it is to remove
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Asking for a quote
When you call or email, it’s useful to know:
- Any previous sealing or DIY work
- Where the job is, and your postcode
- Photos by email, if that is easy
- Access, such as stairs, a lift or height

Why deal with it now?
A new conservatory roof is a big job. Where the water is getting in through sealant renewing the joint is the simpler fix. If the roof is the problem, we will say so. In a place like Kalliness, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first.
Why book with us
- A 12-month guarantee on all work
- Experience in homes, commercial sites and hotels
- White, clear, grey or coloured to suit, where the product allows
- We never seal over old sealant
When to call us in Kalliness
Dirt and grease stop silicone sticking. Where the joint wasn’t cleaned and degreased the sealant may lift within a few years.
Look out for these signs:
- Stained, discoloured glazing silicone
- New silicone smeared over old sealant
- Glazing silicone that has cracked or come away
- Water tracking down the inner face of the glass
For jobs in and around Kalliness, choosing the right material for each joint is as important as a tidy finish.

Frames and glazing around Kalliness
Kalliness 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 failed outside joints work against that.
In and around Kalliness, as anywhere, good glazing silicone starts with a clean, dry, properly prepared joint.

Common questions in Kalliness
Is Kalliness within the area you cover?
Yes, Kalliness is covered. Our work covers the whole of Scotland, islands included, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Does the coastal weather in Kalliness affect outside sealant?
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.
Do you work for hotels and businesses?
Yes, regularly. Larger jobs can be planned room by room or area by area.
Can landlords and businesses book you?
Yes. We work in homes, commercial premises and hotels, and we’re fully insured.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will explain our choice.
I rent my home. Can I book you?
We are happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Do you fit new glass or sealed units?
We do not replace glass. We reseal the joints around it and can tell you if a unit seems to have gone.
What do you need from me for a quote?
