Premium Window & Door Materials
Fibreglass Doors
Fibreglass 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
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 Doors
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 Windows
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.
Fibreglass Windows
Fibreglass 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.
Fibreglass frames are up to 8 times stronger than vinyl, allowing for larger glass areas with slimmer frames.
A quality fibreglass window can last 40–50 years or more, making it one of the longest-lasting window materials.
Aluminum Windows
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.

Window and Doors FAQs
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. Many of Kingston's older homes still have their original windows, or windows over 30 years old. Heating costs have climbed a long way since those were installed, and window energy-efficiency technology has improved just as dramatically.
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 some experience in carpentry and more specifically, window installation. It can also lead to water and mold damage throughout the house.
Phased replacement is common and perfectly fine. If you're doing it in phases, it's best organized by section of the house: front, back, sides. Keep the same window material, manufacturer, and colour so the house retains a uniform look.
Proper installation plays a critical role in the performance, durability, and warranty validity of new replacement windows. Our team is experienced and trained, and we work with multiple manufacturers in order to satisfy their warranty requirements.
Ultimately this comes down to homeowner convenience rather than a strict best season, and winter isn't off-limits the way a lot of people assume. Our team preps the windows and surfaces to allow a smooth and quick transition for the new window. This minimizes heat loss and keeps the elements out.
