Forest Hill Workshop • Custom Fabrication
We craft architectural aluminum that withstands the Highveld weather, enhances security, and elevates your lifestyle.
High-grade powder-coated aluminum that will never rust, peel, rot, or need repainting like old steel and timber.
Every frame is cut, mitred, and sealed with millimeter precision in our Forest Hill workshop for smooth glide operation.
EPDM weather gaskets, double woolpile seals, and safety glass options that eliminate cold winter draughts and reduce noise.
Neat, courteous on-site installation by seasoned glaziers with zero brickwork damage and full post-fit cleanup.
Old rusty steel window frames leak cold air in winter, get stuck, and demand endless sandpapering and painting. JLM replaces your rusted steel frames with sleek charcoal architectural aluminum in just hours — completely transform your home's exterior appeal!
Specialized removal technique preserving your plaster and interior paint.
Airtight weather seals keep out dust, cold air, rain, and street noise.
Durable nylon rollers and stainless steel multi-point locking handles.
Architectural grade powder-coat finish that stays pristine for decades.
