Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Glazing silicone in Dounby, done properly
Glazing joints need a sealant made for glass. We use a neutral-cure glazing silicone, which suits glass and most frame materials, finished with a neat, even bead. If you have split or lifting silicone on glass and leaks from the base of a shower screen, we can put it right, on glass-to-glass joints, conservatory frames and glass-to-frame joints alike.
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.
A one-year guarantee comes with the work, just as it does everywhere we cover.

More services for Dounby
Do you need glazing silicone in Dounby?
UV light ages silicone and roof joints get the most sun. It goes brittle, cracks and stops sticking to the glass and frame.
These are the problems we are asked about most:
- Water getting into a conservatory at the joints
- Black or yellowed silicone on glass joints
- Water running down inside the glass
- A quick top-up bead that didn’t last
Around Dounby, as everywhere, glazing silicone is only as good as the preparation behind it.
Questions to ask before you book
- What insurance they hold
- What the quote includes, VAT included or not
- Whether they seal over old material or remove it
- The length of the guarantee
Why it’s worth doing now in Dounby
A quick bead over the old sealant might stop a drip for a while, but new silicone will not bond to old, and the leak usually returns. Cutting out and resealing properly lasts. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Ask us for a quote and we will explain what it covers.

What glazing silicone looks like in Dounby
Dounby is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on glazing joints and frame seals, especially on the side facing the sea. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
Historic houses such as Skaill House, about 4 miles west, show how far back building around Dounby goes, and older homes nearby need a sealant that suits their walls.
Dounby is about 12 miles north-west of Kirkwall, in the Orkney Islands. Jobs in Dounby get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Dounby is one of 51 towns and villages in the Orkney Islands we cover for glazing silicone.

Related advice
How the job changes by surface
Rooflights
We reseal the glazing joints on rooflights. Leaks from the roof itself need a roofer.
Glass-to-frame joints
Old sealant is removed carefully from the glass before new glazing silicone goes in.
Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Do you cover smaller places like Dounby?
Yes. Dounby is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland, including the islands, where work is planned around ferry crossings. Let us know about access, parking and anything unusual about getting there when you book.
What sealant do you use on glazing?
Glass needs a sealant made for glazing. We use neutral-cure glazing silicone and anti-fungal silicone in wet areas.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Is it enough to run a bead over the old sealant?
Silicone doesn’t stick to silicone and water gets between the layers. We cut out the old sealant first.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Do you work for letting agents?
Yes, regularly. Several properties can go on one quote.

Jobs vary more than people expect. What affects the quote:
- Which sealant suits the joint
