Problem with your glazing joints in Hillswick? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.

How we handle glazing silicone in Hillswick
Glazing silicone that has yellowed, blackened or come away looks poor and can leak. It comes off cleanly, without marking the glass before the new bead goes in. We are often asked to deal with new silicone smeared over old sealant and leaks from the base of a shower screen, on glass-to-glass joints, conservatory frames and shower screens.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain.
There’s a 12-month guarantee on every job.

Is a special sealant needed for glass?

How much does glazing silicone cost in Hillswick?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Where are you based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
How long does glazing silicone take?
A typical job takes a few hours, depending on how many joints need doing, including the preparation. Your quote will say how long we expect yours to take.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What we do, step by step
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes a few hours, depending on how many joints need doing, depending on the amount of work. Somewhere like Hillswick may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We start by finding the leak and making sure sealant is the cause.
- We cut out the failed silicone, taking care of the glass and frame.
- Surfaces are cleaned with a solvent suited to glass and the frame.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep air moving in the conservatory
- Use a gentle glass cleaner and a soft cloth
- Keep scrapers and blades away from the silicone
- Look over the glazing joints once a year
Don’t use blades or scrapers near the bead when you clean. Stick to a soft cloth.
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.
When to call us in Hillswick
Sealant laid over old sealant does not last. Many failed joints we see have been topped up rather than cut out leaving a path for water.
Most people get in touch after spotting one of these:
- Rooflight joints letting water in
- Water escaping where a screen meets the wall
- Split or lifting silicone on glass
- Water running down inside the glass
Around Hillswick, as everywhere, glazing silicone is only as good as the preparation behind it.

Why act early in Hillswick
Topping up old silicone can look like a fix, but silicone does not stick to silicone and water soon finds its way back. A proper reseal is the lasting answer. 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.
Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Hillswick homes and the weather
Hillswick is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
In the older streets around Northmavine Parish Church and Churchyard, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
