Glazing silicone in Longniddry, 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 drips on the inside of a conservatory window and leaking glazing joints on a rooflight, we can help, on glass balustrade bases, conservatory frames and glass-to-frame joints alike.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Every job comes with a 12-month guarantee.

Why act early in Longniddry
A quick bead over the old sealant might stop a drip for a while, but silicone does not stick to silicone and water soon finds its way back. A proper reseal is the lasting answer. In an older home around Longniddry, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
When to call us in Longniddry
Some conservatory leaks are not sealant at all: broken panels, roof problems and blocked gutters can all let water in. That’s why we trace the leak first.
Signs it’s time to call us include:
- Water escaping where a screen meets the wall
- Leaking glazing joints on a rooflight
- Leaks where conservatory glass meets the frame
- Mouldy sealant around glass panels
For landlords with property near Longniddry station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Longniddry: your questions answered
Do you cover smaller places like Longniddry?
Yes, Longniddry is covered. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Is glazing silicone in a coastal place like Longniddry any different?
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?
We can. We remove the old silicone carefully before cleaning and resealing.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Where is Mr Mastic based?

Can you reseal the base of a glass balustrade?
Yes, where the base is finished with sealant. Send us pictures and we will take a look.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Do you work for letting agents?
Yes, we do. Domestic, commercial and hotel work are all part of what we do.
