What affects the quote in Douglas
We don’t publish a price list, because no two jobs are the same. The quote depends on:
- Whether the work is at height
- Working hours on commercial sites
- The size of the job
- The number of rooms or windows
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- Pictures of the joints, sent by email
- Any access issues, like height or stairs
- Where the property is
- Whether it’s a home or a business
To get a quote, email us at info@mrmastic.co.uk and tell us where the job is and what the problem looks like. You’ll have a clear quote before any work starts.
How we handle glazing silicone in Douglas
Many conservatory leaks come down to failed sealant at the glass-to-frame or frame-to-wall joints. We trace the leak to the joint and reseal it and tell you plainly if the cause is something else. Common call-outs are for silicone pulling away from the glass and conservatory leaks at frame and glazing joints, across shower screens, rooflights and conservatory frames.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill.
There’s a 12-month guarantee on every job.

Douglas questions
Can you do glazing silicone in Douglas?
Yes. We work across all of Scotland, and Douglas is part of that. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
Is Douglas within the area you cover?
Yes. Douglas is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we are using and why.
Where is Mr Mastic based?
Our base is Crawley. We work across South East England, London and Scotland.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that usually means someone at home.
How much does glazing silicone cost in Douglas?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Common problems we fix in Douglas
Sealant laid over old sealant does not last. Plenty of leaks come from a quick top-up over the old bead, and water gets between the layers.
Keep an eye out for these signs:
- Mouldy sealant around glass panels
- Leaks from the base of a shower screen
- New silicone smeared over old sealant
- Leaking glazing joints on a rooflight
Around Douglas, as everywhere, glazing silicone is only as good as the preparation behind it.
Before you book anyone
- What the quote includes, VAT included or not
- Which colour the sealant will be
- Is the old sealant removed completely?
- How hidden problems are handled
Why act early in Douglas
Leaks get worse, not better. Left, water can mark floors, damage plaster and rot timber so early action saves a bigger repair. In an older home around Douglas, damp from a failed joint can get into timber and plaster.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and send you a clear quote before work begins.

See our cost guide or customer reviews.
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Keep scrapers and blades away from the silicone
- Look over the glazing joints once a year
- Stick to mild cleaners on glass
- Don’t leave a drip for the next storm
Keep conservatory gutters clear, so water drains away from the joints. Overflowing gutters can cause leaks of their own.
Conservatory leaks rarely stay small. Water travels along the frame and into the wall so it’s best dealt with straight away.
What we do, step by step
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours, depending on how many joints need doing. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- First we agree the joints to be done.
- Old sealant is removed from the glass and frame.
- The surfaces are cleaned with a suitable solvent.
- We apply and tool the new silicone.
- The joints are checked before we leave.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in
- Mention any tricky access
How to get a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.

Frames and glazing around Douglas
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. 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.
In the older streets around St Bride's Chapel, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
