Glazing silicone in Racks
Many conservatory leaks come down to failed sealant 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 can’t fix, we’ll tell you. We work on glass-to-glass joints, shower screens and glass balustrade bases, and common reasons people get in touch are sealant that was laid over old silicone and failed and leaks from the base of a shower screen.
Outdoor sealant needs a dry surface, so window work around Racks is planned around the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
Every job is covered by our one-year guarantee, wherever you are in Dumfries and Galloway.

Why deal with it now?
Dealing with a leaking shower screen early protects the floor and ceiling. Water from a failed joint can soak into the floor before you notice. In a place like Racks, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, send an email to info@mrmastic.co.uk and we’ll give you an honest view and a quote.

For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can go on one quote.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Surface by surface
Glass-to-frame joints
The sealant must stick to glass and frame alike. We choose a product that suits both.
Rooflights
Rooflights get the full force of the weather. The sealant around the glass and frame wears faster than most.

Can you fix a leaking conservatory?

Can you match the sealant colour?
We help you choose a colour that suits. The choice depends on the product the joint needs.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we’re done.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
What does glazing silicone cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
What should I tell you?
Let us know what needs doing and where, with pictures by email if possible. If we need more, we will ask.
Looking after it afterwards
So the new joints stay in good condition:
- Check the silicone on glass every year or so
- Get a new leak looked at quickly
- Stick to mild cleaners on glass
- Wipe the screen down after showering
Gentle products are best near the sealant. Strong solvents can soften or mark it.
A leaking shower screen may not show at first. Water can soak into the floor or reach the room below long before you see it.
How it works
We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. The job usually takes a few hours for most jobs, and we tell you how long to leave it before we go. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First, we check where the water gets in.
- We remove the old sealant carefully.
- The joint is cleaned and degreased.
- We lay the new bead and tool it smooth.
- We check the finished joints and test with water where it’s safe.
Before we arrive
- Let us know about parking restrictions
- Let us know about earlier repairs to the joints
- Keep pets and children clear of the area while we work

Racks homes and the weather
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional 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 Dumfries station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows. In and around Racks, as anywhere, good glazing silicone starts with a clean, dry, properly prepared joint.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, 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.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
