Ideal For

Commercial windows improve a building's appearance, increase natural light, and help reduce energy costs by providing better insulation than older window systems. Modern double- and triple-pane commercial windows can significantly reduce heat transfer, and buildings with energy-efficient windows often experience lower heating and cooling costs while providing a more comfortable environment for employees and customers.
Commercial entry doors are designed to withstand thousands of daily openings while providing enhanced security, accessibility, and weather protection. High-quality aluminum or steel commercial doors require minimal maintenance and can last for decades when properly installed, making them a smart long-term investment for any business.


A modern glass storefront creates a professional first impression while maximizing visibility for your business. Studies have shown that natural daylight can improve employee well-being and productivity, while an attractive storefront helps businesses stand out and encourages more customers to enter.
Large commercial window and curtain wall projects involve installing expansive glass systems on office buildings, hospitals, schools, hotels, apartment complexes, and retail developments. These high-performance glazing systems maximize natural daylight, improve energy efficiency, and create a modern architectural appearance while withstanding wind, water, and thermal expansion.
Industry Facts


Fiberglass doors are engineered to mimic real wood grain while resisting the warping, rotting, and moisture damage wood is prone to. They're more energy efficient than steel because they don't conduct heat, and their polyurethane core acts as built-in insulation — a strong pick for Kingston's cold winters. They're also lightweight, easy to handle during installation, and resist warping better than either steel or wood.

Steel doors are the go-to choice for homeowners prioritizing security and budget. They offer strong, reliable protection against forced entry and harsh weather, and they're more energy efficient than wood, though they can conduct heat and get warm to the touch on sunny days. The tradeoff: they're prone to dents, scratches, and rust over time.

Wood remains a top choice for its natural warmth, custom detailing, and classic curb appeal — ideal for heritage-style homes (Great for historic Kingston !) Wood doors have relatively poor insulation and are the least energy efficient of the three materials, and they require more upkeep, but for character and craftsmanship, nothing else quite matches it.

Vinyl is the most popular window material in North America thanks to its excellent insulation, durability, and affordability. Unlike wood, vinyl won't rot, peel, or require painting, making it virtually maintenance-free while helping homeowners reduce heating and cooling costs.
Vinyl windows account for more than 60% of the residential replacement window market.
Multi-chamber vinyl frames provide excellent thermal insulation and can last 20–40 years with proper maintenance.

Fiberglass windows are one of the strongest and most energy-efficient options available. They resist warping, expanding, and contracting during extreme Canadian temperatures while providing outstanding durability and a sleek modern appearance.
Fiberglass frames are up to 8 times stronger than vinyl, allowing for larger glass areas with slimmer frames.
A quality fiberglass window can last 40–50 years or more, making it one of the longest-lasting window materials.

Modern aluminum windows feature a thermal break—an insulated barrier inside the frame—that dramatically improves energy efficiency compared to older aluminum designs. Their slim frames maximize natural light while offering exceptional strength, making them ideal for contemporary homes and large window openings.
Thermally broken aluminum windows can reduce heat transfer by more than 50% compared to traditional aluminum frames.
Aluminum frames are highly resistant to rust, corrosion, and warping, with an expected lifespan of 30–45 years.

Signs include drafts, rising energy bills, windows that stick or won't stay open, condensation between panes, and visible rot or damage — drafts and energy loss are the most commonly cited signs, along with visible damage like cracked panes or warping. A lot of Kingston's older community often have original or 30+ year old windows. Since then we know that heating costs have gone way up, but the window energy efficient technology has also drastically increased.
This trips people up constantly — replacement windows fit into an existing frame, while new construction windows are used when the frame is also being replaced or it's a new build.
Poor installation can negatively impact performance and will likely void the window's warranty, so it's best left to professionals unless you have advanced skills. It can also lead to water and mold damage through out the house!
Phased replacement is common and fine — if doing it in phases, it's best organized by section of the house (front, back, sides). Also, be sure to keep the same window material, manufacturer, and colour, so the house retains a nice uniform look.
Proper installation plays a critical role in the performance, durability, and warranty validity of new replacement windows. Our team is experiences and trained and work with multiple manufacturers in order to satisfy their warranties.
Ultimately this comes down to homeowner convenience rather than a strict "best" season — a good one to address directly since people assume winter is off-limits. Our team preps the windows and surfaces to allow a smooth and quic transition for the new window. This minimizes heat loss, and keeps the elements out !
