Glazing silicone in Thurso, done properly
Glass and frames expand and contract differently, and the silicone between them takes the strain. Once it splits or comes away, water finds a way through. We cut it out and reseal with a glazing silicone suited to the joint. If you are dealing with leaks from the base of a shower screen and glass-to-glass joints that have split, we can put it right, whatever the surface.
In a town like Thurso, plenty of homes have harled (roughcast) walls, and the joint between a frame and rough harling needs a sealant that can grip and flex. A thin bead that hasn’t been worked into the surface soon lets water behind it.
You get a 12-month guarantee, the same in Thurso as everywhere else we work.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out 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.
Frames and glazing around Thurso
Thurso 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. 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.
For landlords with property near Thurso station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. Managing a site like Thurso High School? Then larger buildings have plenty of frames, and the mastic around each one ages.

FAQs for Thurso
Can you help a landlord with a rental near Thurso station?
Yes, rental work is part of what we do. Just send an email to info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
Does living near the coast affect glazing silicone in Thurso?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Do you reseal glass shower screens?
Yes, we do these often. The screen is resealed with anti-fungal silicone suited to bathrooms.
Can you reseal the base of a glass balustrade?
Yes, we reseal the joint at the base channel. We don’t install or replace the glass.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before resealing.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
What sealant do you use on glazing?
A glazing silicone chosen for the joint. Neutral-cure products suit most glass and frames.
What does glazing silicone cost?
Size, access and the old material all affect the cost. Ask us for a quote.
The process
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours, depending on how many joints need doing. A visit in Thurso needs three things planned: access, parking and where the work is. Outdoor jobs need a dry day, so they can move if the weather turns.
- 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.
- We clean the joint with a solvent that suits the glass and frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- The finished joints are checked and, where it’s safe, tested with water.
How to prepare
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints
- Clear the area around the work

What affects the cost of glazing silicone
Every job gets its own quote. These are the things that affect it:
- Any mould that needs treating
- Whether old sealant or filler has to be cut out
- The type of sealant required
- Working hours on commercial sites
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Call for a quick quote and we will go through it with you.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- How we’d reach the joints
- Where the property is
- Roughly how big the job is
- A few photos by email, if you can
There’s no standard price list. Instead, your job gets its own clear quote. To arrange one, send an email to info@mrmastic.co.uk.
Different surfaces, different methods
Rooflights
A rooflight faces rain and sun from above. Its sealant ages faster than vertical joints.
Shower screens
Silicone holds the water in on frameless screens. We renew it without marking the glass.
Landlord and commercial work in Thurso
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
If you manage several properties in or around Thurso, jobs at different addresses can be quoted together. Send us the addresses and the work at each, and photos by email help.
Also in Thurso
Leave it or put it right?
If the problem is a misted unit or a broken panel, sealant will not help. We will tell you that rather than seal it anyway and point you to a glazier or roofer. In flats with a shared stair in Thurso, a leak from a failed seal can affect the flat below too, and that’s much harder to put right.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first.
