Glazing silicone in Dalswinton, done properly
Not every silicone suits glass. Our applicators use neutral-cure glazing silicone that is suited to glass and the frame, and we tool it to a neat, even finish. If you’re dealing with shower screens leaking along the wall or tray and cracked silicone between glass panels, we can help, whatever the surface.
Outdoor sealant needs a dry surface, so window work around Dalswinton is planned around the weather. Tell us about access to all the windows and doors, upstairs included.

Frames and glazing around Dalswinton
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Clean glass with a mild cleaner and a soft cloth
- Check the silicone on glass every year or so
- Clear the conservatory gutters regularly
- Keep scrapers and blades away from the silicone
Follow the cure time we give you before the joints get wet. From then on, a mild glass cleaner is all it needs.
Drips or damp near a glazing joint shouldn’t be ignored. The cause may be sealant or another part, and we’ll tell you which.
When something else is needed
We’ll always be straight with you, so here’s what sealant can’t fix:
- Rotten or badly damaged frames
- Structural problems with a conservatory roof
- Cracked or broken glass
If you’re not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer.

When to call us in Dalswinton
Dirt and grease stop silicone sticking. Where the joint wasn’t cleaned and degreased the sealant may lift within a few years.
Any of these means the joints need attention:
- Failed sealant around rooflight glass
- Drips on the inside of a conservatory window
- Stained, discoloured glazing silicone
- New silicone smeared over old sealant
For an older house near a landmark such as Dalswinton Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Questions to ask before booking
- Whether the sealant suits the joint
- Who does the work, and how experienced they are
- Whether you can choose the colour
- Whether they’re fully insured

FAQs for Dalswinton
Is Dalswinton in your area for glazing silicone?
Yes, Dalswinton is within the area we cover. We work across all of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing, and we’ll send you a clear quote.
Is there a guarantee on glazing silicone in Dalswinton?
All our work, in Dalswinton and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Can I choose the sealant colour?
In most cases you can choose. We will tell you which colours the right product comes in.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us and we’re fully insured.
Can you replace a misted double-glazed unit?
That’s not something we do. A misted unit has failed inside and needs replacing by a glazier.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
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.
Why it’s worth doing now in Dalswinton
A new conservatory roof is a big job. If the leak is a failed sealant joint renewing the joint is the simpler fix. If it’s the roof itself, we will tell you. 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.
Combining jobs into one visit is generally more efficient than separate visits. We’ll give you a clear price for the lot.

How the visit works
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for most jobs. Outside jobs in Dalswinton need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First we agree the joints to be done.
- Old sealant is removed from the glass and frame.
- The surfaces are cleaned with a suitable solvent.
- We apply and tool the new silicone.
- The joints are checked before we leave.
Before we arrive
- Mention if the joints have been sealed before
- Mention any tricky access
- Tell us if parking is tricky
