How we quote for glazing silicone
Every job gets its own quote. These are the things that affect it:
- How many rooms, windows or areas are involved
- Whether there’s mould to deal with
- Whether the work is at height
- Any working-time requirements on site
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
Helping us quote
You do not need to know the technical terms. Just tell us:
- The rough size of the job
- Where the job is, and your postcode
- Whether it has been sealed before
- Access, such as stairs, a lift or height

Glazing silicone in Gelston
We don’t replace glass and a misted double-glazed unit needs a glazier. Our work is the sealant joints, which is where many leaks start. We work on glass-to-frame joints, glass balustrade bases and rooflights, and common reasons people get in touch are new silicone smeared over old sealant and glazing silicone that has cracked or come away.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
You get a 12-month guarantee, the same in Gelston as everywhere else we work.

Can you fix a leaking conservatory?
Often, if the leak is at a sealant joint. We find where the water gets in first, so you know what you are paying for.
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.
What does glazing silicone cost?

Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Can you do several jobs on one visit?
Yes. Just list everything you need and we will quote it together.
Is a special sealant needed for glass?
A neutral-cure glazing silicone that suits the glass and frame. Shower screens get anti-fungal silicone.

Advice
Frames and glazing around Gelston
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
In and around Gelston, as anywhere, good glazing silicone starts with a clean, dry, properly prepared joint.

What we’re called out for in Gelston
Some conservatory leaks are not sealant at all: broken panels, roof problems and blocked gutters can all let water in. We find the cause before we seal anything.
Signs it’s time to call us include:
- Rooflight joints letting water in
- Water getting into a conservatory at the joints
- Glass-to-glass joints that have split
- Leaks from the base of a shower screen
In the older streets around Kirkland Of Gelston, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What to look for in a quote
- Are they insured?
- Is VAT in the price?
- How the joint is cleaned and prepared
- The length of the guarantee
Aftercare tips
A little care helps the new joints last. Our advice:
- Wipe the screen down after showering
- Keep conservatory gutters clear of leaves
- Act on drips or damp patches early
- Open vents or windows to let moisture out
Gentle products are best near the sealant. Harsh solvents may damage the bead.
Cracked glazing silicone means the joint has failed. Resealing now is a small job compared with fixing water damage later.
Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
When it is not the sealant
Sealant isn’t the answer to every problem, and we’ll tell you before we start. It won’t solve:
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- Failed flashing around a conservatory
- A sagging or failing conservatory roof
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think.
