Glazing silicone for homes and businesses in Grimbister
Conservatory leaks often start at a sealant joint, where glass meets frame or frame meets wall. We trace the leak to the joint and reseal it and tell you plainly if the cause is something else. We work on glass-to-frame joints, glass-to-glass joints and rooflights, and common reasons people get in touch are glass-to-glass joints that have split and new silicone smeared over old sealant.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will give you a quote.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Frames and glazing around Grimbister
Grimbister is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on glazing joints and frame seals, especially on the side facing the sea. Work on the islands has to be planned around ferry crossings and the weather, so give us as much notice as you can.
Around Grimbister, as everywhere, glazing silicone is only as good as the preparation behind it.
Grimbister is about 5 miles west of Kirkwall, in the Orkney Islands. Homes, rented property, offices and hotels in Grimbister can book us for glazing silicone. Every job comes with our one-year guarantee. 51 places in the Orkney Islands are on our list, large and small.

Keeping the joints in good condition
Looking after new joints is easy:
- Get a new leak looked at quickly
- Avoid strong solvents on or near the sealant
- Stick to mild cleaners on glass
- Avoid scraping close to the bead
Look over the glazing joints every year or so. Catching a split early keeps the repair small.
Damp patches, drips and condensation along a joint are worth checking. The cause may be sealant or another part and we will find out which.
Why deal with it now?
Leaks get worse, not better. Left, water can mark floors, damage plaster and rot timber, so it pays to deal with it early. In a place like Grimbister, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.

Common problems we fix in Grimbister
The wrong sealant is a common cause. Some products don’t bond well to glass and vinegar-smelling acetoxy silicone can attack some metals.
If you can see any of these, it’s time to have the joints looked at:
- Silicone pulling away from the glass
- Water tracking down the inner face of the glass
- New silicone smeared over old sealant
- Leaking glazing joints on a rooflight
For jobs in and around Grimbister, choosing the right material for each joint is as important as a tidy finish.
Before you book anyone
- Whether they seal over old material or remove it
- What happens if they find a problem under the old sealant
- Whether the sealant suits the joint
- What insurance they hold
Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Common questions in Grimbister
Is glazing silicone in a coastal place like Grimbister any different?
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.
Do you cover smaller places like Grimbister?
Yes, Grimbister 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.
How long does the job take?
A typical job takes anything from an hour or two to most of a day, depending on the size of the job. We’ll confirm how long when we quote.
Is the work guaranteed?
All our work has a one-year guarantee, and we’re fully insured.
Can you fix a leaking conservatory?
In many cases, as long as sealant is the cause. We find where the water gets in first before any sealing.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Is a special sealant needed for glass?
We use a neutral-cure glazing silicone that suits the glass and frame. Shower screens get anti-fungal silicone.
