JL Windows and Doors supplies custom windows and doors Melbourne builders, homeowners and designers can specify for new homes, renovations and replacement projects. We provide project-based quotations for aluminium window and door systems, glazing, colours, hardware, delivery and installation requirements.
Our Keysborough team helps customers compare practical options rather than treating every opening the same. The final selection should suit the architectural drawings, energy report, room use, site conditions, appearance and project budget.
Custom Window and Door Consultation
A clear quotation starts with the right information. Builders can provide architectural drawings, window and door schedules and an energy report where available. Homeowners can send approximate measurements and clear photographs for an initial renovation or replacement discussion.


Options Reviewed During Quotation
- Window and door type, quantity and dimensions
- Opening direction and panel configuration
- Frame system, glazing and colour

Aluminium Door Options
Door packages may include sliding, stacker, hinged, French and bi-fold configurations. The appropriate layout depends on access, usable wall space, panel sizes, desired clear opening and product limitations. Compare our aluminium door range and sliding and stacker doors.
Glass, Energy Performance and Privacy
Glass and frame performance should be selected for the specific project. Options may include single glazing, double glazing, Low-E glass, obscure glass for privacy, laminated or toughened glass where required, standard aluminium frames and thermally broken systems. Energy reports and applicable project requirements should be reviewed before the final specification is confirmed. Read how a complete window and door system coordinates frames, glass, seals, drainage and hardware.
Installation for New Builds and Renovations
Installation scope varies between new construction and replacement work. New-build projects require coordination with the builder, opening preparation, flashing, drainage and surrounding construction. Replacement projects may involve removal of existing frames, assessment of reveals and finishes, protection of adjacent surfaces and disposal arrangements stated in the quotation.
Installation Details
- Final dimensions and access checked where required
- Frames positioned, fixed, sealed and adjusted
- Tracks, locks and opening panels tested

Window and Door Replacement
For homeowners replacing older windows and doors, photographs and rough sizes can help us understand the project before an on-site measure is arranged where required. Existing wall construction, access, internal reveals, external finishes and the desired installation scope all affect the quotation.
