Landlord and commercial work in Perth
We also work for property managers and facilities teams. Several sites can be quoted together, and we are fully insured for the work.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
About our glazing silicone in Perth
Conservatory leaks often start at a sealant joint at the glass-to-frame or frame-to-wall joints. We find the joint that is letting water in and renew it, and if it’s something sealant cannot fix, we will tell you. We work on rooflights, glass balustrade bases and glass-to-frame joints, and people most often call us about water escaping where a screen meets the wall and glazing silicone that has cracked or come away.
Harled walls are common in Scottish towns like Perth, and the joint between a frame and rough harling needs a sealant that can grip and flex. A bead that sits on top of the harling rather than in the joint soon lets water in.
Your job is guaranteed for a year, as with all our work.

Perth: your questions answered
Is there a guarantee on glazing silicone in Perth?
All our work, in Perth and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Can you help a landlord with a rental near Perth 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.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Why not top up the existing silicone?
Topping up is a common cause of leaks. We remove the old silicone, clean the joint and reseal.
What sealant do you use on glazing?
A glazing-grade silicone is best. We use neutral-cure glazing silicone with anti-fungal products in bathrooms.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
What does glazing silicone cost?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Honest limits
To be straight with you, there are a few things sealant will not fix:
- Leaks from the roof covering or flashing (a roofer’s job)
- Structural problems with a conservatory roof
- A sealed unit that has misted inside
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.
What we seal
- Rooflights
- Glass balustrade bases

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
The process
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for most jobs, and the area is left clean. For a job in Perth, tell us where the work is, how to get in and where to park. Outside work depends on the weather, as sealant needs a dry surface.
- We start by finding the leak and making sure sealant is the cause.
- Old silicone is cut away from the glass and frame without scratching either.
- The glass and frame are cleaned and degreased.
- We apply a neutral-cure glazing silicone and tool it smooth.
- The finished joints are checked and, where it’s safe, tested with water.
Before we arrive
- Try not to wet indoor joints just before the visit
- Let us know about parking restrictions
- For business premises, tell us about site rules or sign-in

Frames and glazing around Perth
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
If you look after a building such as Perth High School, the mastic around its windows and doors needs looking after like any other building’s. Rented homes near Perth station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows.
Perth is about 33 miles north of Edinburgh, in Perth and Kinross. Every kind of property in Perth can book us for glazing silicone. Every job comes with our one-year guarantee. Perth is one of 107 places in Perth and Kinross we cover. Dundee is on our list too, around 19 miles away.
Our applicators cover all of PH1 and PH2 for glazing silicone. Whether your property is on Simpson Square, High Street and Moredun Square or a nearby road, our applicators can take on the job.

How the job changes by surface
Conservatory frames
Exposed frame joints wear with the weather. Renewed sealant keeps water out.
Glass balustrade bases
The base joint is cut out and resealed. We don’t install or replace glass.
What happens if it’s left?
Topping up old silicone can look like a fix, but silicone does not stick to silicone and water soon finds its way back. Cutting out and resealing properly lasts. Scottish weather finds any gap, and in a town like Perth, failed outside joints soon let damp into walls. Indoors, failed sealant lets water into floors and ceilings.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first.
