At Delco Windows and Doors, we provide wholesale window supply in Toronto, with in-house manufacturing and a selection of more than 50 window and door styles. Our product range includes vinyl, aluminum-clad, and wood-hybrid options so that you can compare materials based on your project's design and performance needs.

Our team also provides design consultation, window installation, and aftercare. This allows you to discuss product specifications and available services before deciding how to proceed with your order.

Window Supplier and PVC Windows Supplier

As a window supplier in Toronto, we offer vinyl (UPVC) windows in multiple operating styles, colors, and finishes. PVC window frames resist moisture and don't require periodic painting, making them ideal for customers who want to reduce routine frame maintenance. Available configurations include casement, awning, hung, and sliding windows so that you can choose products based on each opening's dimensions and ventilation needs. Our team can discuss frame options, glazing requirements, and customization choices before you decide which windows to purchase.

Vinyl Window Installation and Replacement

Replacing deteriorating window frames can address problems such as damaged seals, difficult operation, and air leakage around existing windows. Our vinyl window installation and replacement service provides customers with new windows selected for their opening dimensions, preferred operating styles, and design requirements. Our certified, insured in-house installation team handles the installation work without outsourcing it to another company.

Single Hung Window Installation

Our single-hung window installation service suits older residences, rental properties, and rooms where a straightforward ventilation option is sufficient. With a fixed upper sash and a movable lower sash, these windows give a familiar look while letting fresh air enter from below.

Double Hung Window Installation

Bedrooms on upper floors and rooms with limited exterior access can benefit from windows that provide more than one ventilation option. With our double-hung window installation service, you can open the upper sash, lower sash, or both to adjust airflow without swinging the window outward. This design is particularly useful for Toronto homeowners replacing traditional vertical windows who want to retain their property's original appearance while gaining greater control over ventilation.

Slider Window Installation

Slider windows open horizontally, with an operable sash that moves along a track instead of swinging outward. This configuration works well for openings near exterior walkways, patios, or other areas where an outward-opening window could interfere with surrounding space. Our slider window installation service offers window options that combine horizontal operation with your preferred frame materials and finishes.

Double Slider Window Installation

Double slider windows have two horizontally sliding sashes, allowing occupants to open either side. This configuration provides more flexibility than a single-slider design, which typically has one operable sash and one fixed section. Our double-slider window installation service suits customers who want horizontal operation with the option to ventilate from either side of the opening.

Picture Window Installation

Our picture window installation service is ideal for living rooms overlooking a backyard, stairwells that need additional daylight, and dining areas where an unobstructed exterior view is a priority. These fixed windows do not open, making them suitable for spaces where other windows provide ventilation. We offer different frame materials, glazing options, dimensions, and finishes, so you can choose a picture window that complements your property's design.

Tilt & Turn Window Installation

For homeowners who want flexible ventilation and easier access to exterior glass, our tilt-and-turn window installation service offers a practical solution. These windows are ideal for bedrooms, upper-floor apartments, and rooms where you prefer to clean the exterior glass from inside. The sash tilts inward at the top for controlled ventilation or swings inward for a wider opening and easier cleaning.

Wood Windows

Preserving the architectural character of an older Toronto property often requires careful consideration of window materials and finishes. Our wood window options are ideal for homeowners renovating traditional residences, updating heritage-style interiors, or seeking a natural wood appearance that complements existing trim and cabinetry. Delco offers wood-hybrid windows that combine wood with other materials, providing additional design and performance options.
