Glazing & conservatory sealant in Bielside, East Lothian
Glazing silicone in Bielside from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Conservatory leaks at frame and glazing joints
- Water escaping where a screen meets the wall
- Mouldy sealant around glass panels
Keeping the joints in good condition
After the cure time, these simple habits help:
- Do not use a blade near the sealant
- Use a gentle glass cleaner and a soft cloth
- Ventilate the conservatory to cut condensation
- Use gentle products around the joints
Keep conservatory gutters clear, so water drains away from the joints. Overflowing gutters can cause leaks of their own.
Damp patches, drips and condensation along a joint are worth checking. It may be sealant, or something else and we will find out which.
How we handle glazing silicone in Bielside
Glass, frames and walls all move at different rates, and the silicone between them takes the strain. Once it splits or comes away, water finds a way through. We replace it with a glazing silicone that suits the glass and frame. If you’re dealing with leaks where conservatory glass meets the frame and sealant that was laid over old silicone and failed, we can help.
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.

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
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. Everything old must be removed first.
How the visit works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours, depending on how many joints need doing, including the tidy-up. Outdoor work around Bielside depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We find where water is getting in and check whether it’s a sealant joint.
- We cut out the failed silicone, taking care of the glass and frame.
- We clean the joint with a solvent that suits the glass and frame.
- New glazing silicone goes in and is tooled to a neat finish.
- We check the joints and, where safe, run water over them.
Getting ready for the visit
- Mention any tricky access
- Let us know about parking restrictions

When it isn’t the sealant
A few problems are outside what sealant work can do:
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- Leaks from the roof covering or flashing (a roofer’s job)
- A sagging or failing conservatory roof

Windows and doors in Bielside
Bielside is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
For an older house near a landmark such as Belhaven Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Questions from Bielside
Is Bielside within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Does the coastal weather in Bielside affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Do you guarantee glazing sealant work?
Our one-year guarantee covers every job.
Can tenants book the work?
We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Bielside and the rest of East Lothian.
What does glazing silicone cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before work begins.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Common problems we fix in Bielside
Heat and cold make glass and frames move, and they do not move by the same amount. In time, the sealant splits or pulls away.
Any of these means the joints need attention:
- Water getting into a conservatory at the joints
- Failed sealant around rooflight glass
- Water escaping where a screen meets the wall
- Water running down inside the glass
Letting a property close to Dunbar station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Leave it or put it right?
Fixing a leaking screen early protects what’s underneath. A small leak can reach the floor below before it shows. Around Bielside, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
