Tell us about the opening
Most jobs start with a short conversation: what you want to fit or replace, where the property is, and roughly how big the openings are. From there we arrange to measure and give you a written quotation.
We supply and install, or install units you already have. Homes and businesses, new builds, renovations and replacements of old doors and windows are all work we take on.
Quotations are free. A call-out fee of R200 applies only if you do not accept the quote.

Aluminium doors
Sliding doors and sliding folding doors, sized to the opening and finished in the colour you choose.
A sliding door keeps its glass in line and moves one panel past another, so nothing swings into the room. A sliding folding door folds its panels together to one side and opens almost the full width of the wall. Which suits you depends on how you use the opening, how much wall there is beside it, and how exposed that side of the house is. Read more about aluminium doors.
Aluminium Sliding Doors
Panels that slide past each other on a track, from a simple two-panel door to stacking doors across a full wall.
Aluminium Sliding Folding Doors
Hinged panels that fold to one side and open almost the whole width of the wall.
Aluminium windows
Three ways for a window to open, each with its own strengths.
Side hung windows
Hinged on the side and pushed open outward like a small door. The most air of the three, good for bedrooms and living areas.
Top hung windows
Hinged along the top and opened from the bottom. The sash shelters the gap, so it can stay open in light rain. A common choice for bathrooms and kitchens.
Horizontal sliding windows
One sash slides across the other inside the frame. Nothing sticks out, which suits windows next to paths, patios and narrow side passages.

Shop fronts and commercial glazing
Aluminium shop fronts for retail units, offices and other business premises: fixed glass, top lights and an entrance door framed as one system. We also install glazed aluminium partitions and doors inside offices.
If the premises have to keep trading while we work, say so when you request a quote so the installation can be planned around it.
