How we handle glazing silicone in North Lochs
Glass replacement is not something we do, and misting between panes means a failed sealed unit. Our work is the sealant joints, which is where many leaks start. We work on shower screens, glass-to-glass joints and rooflights, and common reasons people get in touch are leaking glazing joints on a rooflight and stained, discoloured glazing silicone.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Big or small, it’s backed by our 12-month guarantee.

For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Avoid scraping close to the bead
- Clean glass with a mild cleaner and a soft cloth
- Don’t leave a drip for the next storm
- Open vents or windows to let moisture out
Keep the new joints dry for as long as we advise so the silicone can set properly. From then on, a mild glass cleaner is all it needs.
Conservatory leaks rarely stay small. Water runs along frames and down walls so it’s best dealt with right away.
What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes anything from an hour or two to most of a day, depending on the size of the job and we leave things clean and tidy. In smaller Scottish places, parking is normally 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 agree the joints to be done.
- Old sealant is removed from the glass and frame.
- We clean and prepare the joint.
- New glazing silicone goes in and is finished neatly.
- The joints are checked before we leave.
Preparing for the visit
- Move anything stored near the joints
- Tell us if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive

Related advice
Leave it or put it right?
Glazing joints need a sealant made for the job. A general-purpose tube may not bond well or may react with the frame, so we use neutral-cure glazing silicone. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please drop us a line at info@mrmastic.co.uk and we will talk you through it.

Common questions in North Lochs
Does the coastal weather in North Lochs affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Is North Lochs within the area you cover?
Yes, North Lochs is covered. Our work covers the whole of Scotland, islands included, and smaller places are part of that. Longer journeys are simply planned in advance.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
How long does glazing silicone take?
A typical job takes a few hours, depending on how many joints need doing. Your quote will say how long we expect yours to take.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Do you reseal glass shower screens?
We can. We remove the old silicone carefully before cleaning and resealing.
Will resealing stop my conservatory leaking?
That depends where the water is getting in. Failed glazing and frame joints can be resealed, but roof panels and structural problems need a conservatory specialist or roofer.
Do you work for landlords and businesses?
Yes, we do. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.
Glazing silicone in North Lochs: local notes
North Lochs is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. The west of Scotland is wetter than the east, which means glazing joints and frame seals has to cope with a lot of rain.
For an older house near a landmark such as Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. In and around North Lochs, as anywhere, good glazing silicone starts with a clean, dry, properly prepared joint.

Different surfaces, different methods
Glass-to-frame joints
We cut the old silicone from the glass without scratching it before new glazing silicone goes in.
Shower screens
Mouldy or lifting sealant on a screen leaks. A full reseal sorts it.
What affects the cost of glazing silicone
We don’t publish a price list, because no two jobs are the same. What we look at:
- The old material and how stubborn it is
- How easy the joints are to reach
- Which sealant suits the joint
- The amount of work
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- The problem you’ve noticed
- How we’d reach the joints
- Photos by email, if that’s easy
- How many joints, rooms or windows are involved
