Glazing Silicone in Scalloway
We cover Scalloway for glazing silicone for conservatories, rooflights, glass panels and shower screens. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Failed joints on frameless glass
- Silicone pulling away from the glass
- A quick top-up bead that didn’t last
Different surfaces, different methods
Glass-to-glass joints
Silicone joins glass panels in many frameless designs. We renew it with a clear or matching glazing silicone.
Glass balustrade bases
We reseal the joint where the glass meets the base channel. Glass fitting is a separate trade.
Glazing silicone in Scalloway, done properly
Glazing joints need a sealant made for glass. Our applicators use neutral-cure glazing silicone that’s suited to glass and the frame, and we tool it to a neat, even finish. If you have water escaping where a screen meets the wall and rooflight joints letting water in, we can help.
In and around a place like Scalloway, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
All our work is covered by a one-year guarantee.

Common questions in Scalloway
Is Scalloway within the area you cover?
Yes, Scalloway is covered. Our work covers the whole of Scotland, islands included, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is glazing silicone in a coastal place like Scalloway any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
What should I tell you?
A short description and the location. If we need more, we will ask.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we are done.
Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Do you reseal glass shower screens?
Yes, it’s a common job. We use anti-fungal silicone suited to bathrooms.
Landlords, agents and businesses in Scalloway
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.
If you manage several properties in or around Scalloway, jobs at different addresses can be quoted together. Send us the addresses and the work at each, and pictures by email help.
Scalloway homes and the weather
Scalloway is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on glazing joints and frame seals, especially on the side facing the sea. Island weather, with its wind and salt spray, is tough on glazing joints and frame seals.
For an older house near a landmark such as Methodist Church, the joint between an old wall and a newer frame is generally the first place rain gets in.
Scalloway is in the Shetland Islands. Our applicators cover glazing silicone for homeowners, landlords and businesses in Scalloway. Scalloway is one of 63 places in the Shetland Islands we cover.

What’s near Scalloway

Common problems we fix in Scalloway
Sealant laid over old sealant doesn’t last. Many failed joints we see have been topped up rather than cut out leaving a path for water.
Any of these means the joints need attention:
- Glazing silicone that has cracked or come away
- Glass-to-glass joints that have split
- Mouldy sealant around glass panels
- Rooflight joints letting water in
In and around Scalloway, as anywhere, good glazing silicone starts with a clean, dry, properly prepared joint.
What to look for in a quote
- What insurance they hold
- Is VAT in the price?
- Whether you can choose the colour
- What preparation is included
Why deal with it now?
Fixing a leaking screen early protects what’s underneath. A small leak can reach the floor below before you notice. In an older home around Scalloway, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we will go through it with you.

Keeping the joints in good condition
So the new joints stay in good condition:
- Check the gutters above the glazing for debris
- Avoid strong solvents on or near the sealant
- Use a gentle glass cleaner and a soft cloth
- Keep scrapers and blades away from the silicone
Keep the new joints dry for as long as we advise. From then on, a mild glass cleaner is all it needs.
Conservatory leaks rarely stay small. Water runs along frames and down walls, so get it looked at when you first see it.
What affects the cost of glazing silicone
There’s no set price list. What we look at:
- Any mould that needs treating
- Any working-time requirements on site
- How easy the joints are to reach
- How much there is to do
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and agree the price before starting.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- Access, such as stairs, a lift or height
- The address or postcode of the job
- What the problem is, such as mould, gaps, leaks or cracking
- Pictures of the joints, sent by email
Asking for a quote is easy: let us know the job and the location. A few photos by email make the job easier to understand, and we will take it from there.
How the visit works
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours, depending on how many joints need doing. For a place like Scalloway, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
- A neutral-cure glazing silicone is applied and tooled.
- Each joint is checked and, where possible, water-tested.
Before we arrive
- Clear the area around the work
- Mention if the joints have been sealed before
- Mention any tricky access
