Windows and doors in North Dell
North Dell 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. North Dell is in the west of Scotland, which is wetter than the east, which means glazing joints and frame seals has to cope with a lot of rain.
If you live in an older home near Church of Scotland, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Around North Dell, as everywhere, glazing silicone is only as good as the preparation behind it.
North Dell is about 18 miles north of Stornoway, in Na h-Eileanan Siar. North Dell gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. North Dell is one of 87 places in Na h-Eileanan Siar where we work for glazing silicone.

Glazing silicone in North Dell, done properly
Glazing joints need a sealant made for glass. Our applicators use neutral-cure glazing silicone that is suited to glass and the frame, finished with a neat, even bead. We are often asked to deal with stained, discoloured glazing silicone and rooflight joints letting water in, across glass balustrade bases, rooflights and glass-to-glass joints.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
A 12-month guarantee comes as standard.

Why deal with it now?
Silicone around glazing needs the right product. A general-purpose tube may not bond well or may react with the frame so we choose a glazing silicone instead. Around North Dell, water from a failed joint in an older stone home can soak into timber and plaster.
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

Quotes for glazing silicone in North Dell
Every job gets its own quote. These are the things that affect it:
- The number and length of the joints
- When we can work, for business premises
- The type of sealant required
- The number of rooms or windows
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Access, such as stairs, a lift or height
- Roughly how big the job is
- The type of property
- Whether it has been sealed before
Every job is quoted individually, so start by telling us what you need. Simply email us at info@mrmastic.co.uk and describe the job, and pictures are welcome.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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.
How the visit works
We keep the work tidy and contained to the joints we are treating, so you can get on with your day. Expect the work to take a few hours, depending on how many joints need doing. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- First, we trace the leak and check it’s coming through a sealant joint.
- The old sealant is removed from the glass and frame without scratching them.
- The glass and frame are cleaned and degreased.
- Glazing silicone suited to the joint is applied and tooled.
- We check the joints and, where safe, run water over them.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Try not to wet indoor joints just before the visit
- Clear the area around the work

Looking after it afterwards
So the new joints stay in good condition:
- Check the silicone on glass every year or so
- Act on drips or damp patches early
- Check the gutters above the glazing for debris
- Use gentle products around the joints
Squeegee a shower screen after each shower and let the room air. It helps stop mould getting into the silicone.
Act on black or lifting silicone early. Once it starts to peel, water gets behind it and the problem grows.
When something else is needed
New sealant can’t fix everything, and we’d rather say so up front. It won’t solve:
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- Water coming through the roof rather than a sealant joint
- A sagging or failing conservatory roof
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly before booking.
Surfaces we seal
- Conservatory frames
- Shower screens
- Rooflights
- Glass balustrade bases
- Glass-to-frame joints
- Glass-to-glass joints
What the job involves on each surface
Glass-to-frame joints
Glass-to-frame joints need a sealant that bonds to both. We choose a product that suits both.
Glass balustrade bases
Balustrade bases are exposed outdoors. A sound sealant joint keeps them tidy and dry.
Questions from North Dell
Do you cover smaller places like North Dell?
Yes. North Dell is within the area we cover, which takes in towns, villages and rural addresses. We work across all 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.
Does the coastal weather in North Dell affect outside sealant?
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.
Can you reseal a frameless shower screen?
Yes, it’s a common job. The screen is resealed with anti-fungal silicone made for wet areas.
Will resealing stop my conservatory leaking?
Yes, when the leak is a failed sealant joint. If it’s a broken panel, failed unit or roof problem, we will tell you.
Do you guarantee glazing sealant work?
You get our one-year guarantee to every job we do.
Which silicone is used for glass joints?
We use a neutral-cure glazing silicone suited to glass and the frame. In bathrooms, we use anti-fungal silicone.
Can I choose the sealant colour?
We help you choose a colour that suits. The product needed can limit the range.
Can you replace a misted double-glazed unit?
No. We renew the sealant. Glass and sealed units need a glazier.
