Surface by surface
Conservatory frames
Leaks often start where the frame meets the wall. We cut out the old sealant and reseal.
Glass-to-frame joints
Where glass sits in a frame, silicone keeps water out. A failed bead lets water in.
Glazing silicone for homes and businesses in Castle Douglas
Cracked, stained or lifting silicone on glass looks poor and can leak. It comes off cleanly, without marking the glass before the new bead goes in. We work on rooflights, glass-to-glass joints and conservatory frames, and people most often call us about glazing silicone that has cracked or come away and glass-to-glass joints that have split.
Mastic can only go onto a dry joint, so outside work in Castle Douglas depends on the weather. Let us know about access to every frame, including any upstairs.
Every job comes with a one-year guarantee, wherever you are in Dumfries and Galloway.

Glazing silicone in Castle Douglas: local notes
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
For site and facilities teams at buildings such as Castle Douglas High School, larger buildings have plenty of frames, and the mastic around each one ages.

For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
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.
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Don’t use a blade near the sealant
- Wipe the screen down after showering
- Avoid strong solvents on or near the sealant
- Ventilate the conservatory to cut condensation
Keep conservatory gutters clear, so water drains away from the joints. Overflowing gutters can cause leaks of their own.
Conservatory leaks rarely stay small. Water travels along the frame and into the wall, so get it looked at when you first see it.
Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
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.
