Glazing silicone in Douglas Water, done properly
Many conservatory leaks come down to failed sealant at the glass-to-frame or frame-to-wall joints. We find the joint that’s letting water in and renew it and tell you plainly if the cause is something else. If you are dealing with leaking glazing joints on a rooflight and leaks where conservatory glass meets the frame, we can put it right.
Outdoor sealant needs a dry surface, so window work around Douglas Water is planned around the weather. Tell us about access to all the windows and doors, upstairs included.
There’s a 12-month guarantee on every job.

Why it’s worth doing now in Douglas Water
A leaking joint will not fix itself. Water can damage frames, walls, flooring and furniture so early action saves a bigger repair. In a place like Douglas Water, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please send an email to info@mrmastic.co.uk and we’ll talk you through it.

Questions from Douglas Water
Do you work for landlords with property near Lanark station?
Yes, landlords and agents are among the people we work for. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Is Douglas Water within the area you cover?
Yes, Douglas Water is covered. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Can I add another job to the visit?
Yes. Just list everything you need and you’ll get one quote.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we are using.
Can I choose the sealant colour?
Generally, yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before we start.
Can you just put new silicone over the old?
It does not last. Fresh silicone will not bond to cured silicone, so we remove the old sealant and clean the joint.
Do you fit new glass or sealed units?
We do not replace glass. We look after the sealant joints and can tell you if a unit seems to have gone.
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 will tell you.
How the visit works
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours for most jobs. Outside jobs in Douglas Water need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- 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.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Let us know about stairs, lifts or work at height
- For business premises, tell us about site rules or sign-in

What we’re called out for in Douglas Water
Dirt and grease stop silicone sticking. Where the joint wasn’t cleaned and degreased the sealant may lift within a few years.
If you can see any of these, it’s time to have the joints looked at:
- Glass-to-glass joints that have split
- Water getting into a conservatory at the joints
- Water running down inside the glass
- Leaking glazing joints on a rooflight
In and around Douglas Water, as anywhere, good glazing silicone starts with a clean, dry, properly prepared joint.
Before booking anyone

- What preparation is included
- What insurance they hold
- What happens if the job turns out different
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
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.
Landlord and commercial work in Douglas Water
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.
How the job changes by surface
Glass balustrade bases
The base joint is cut out and resealed. We don’t install or replace glass.
Rooflights
Rooflight glazing joints are cut out and renewed. Leaks from the roof itself need a roofer.
What glazing silicone looks like in Douglas Water
Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Rented homes near Lanark station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
