Repair & Maintenance for Old Single-Hung Windows

Advanced Features of Our Single-Hung Windows

Engineered for long-term performance, our single-hung windows combine proven materials and advanced insulation to handle Canada’s demanding weather. The top features of our windows are:

Operable Lower Sash With Smooth Balance Springs

Our operable lower sash uses high-tension balance springs for controlled, effortless vertical sliding. No slamming, sticking, or slipping, just smooth, quiet function that stays reliable over years of use, even in high-traffic areas like bedrooms and kitchens.

Tilt-In Lower Sash for Easy Cleaning

Cleaning is quick and safe with our tilt-in sash design. The lower sash folds inward, letting you wash exterior glass from inside your home, ideal for upper floors. No ladders or special tools required, making maintenance easier for GTA homeowners.

Energy Star® Certified Glass Units

Every window is built with ENERGY STAR® certified insulated glass units that meet Canada’s most rigorous energy efficiency standards, reducing heat transfer, blocking UV rays, and helping GTA homeowners lower year-round heating and cooling costs.

Low-E Coating & Argon Gas Insulation

We use low-emissivity (Low-E) coatings paired with argon gas-filled chambers between double or triple panes. This advanced glazing system reflects heat in summer, retains warmth in winter, and significantly cuts energy loss through the glass.

Fusion-Welded Vinyl Frames

Our multi-chambered vinyl frames are fusion-welded at the corners for added structural strength and airtight sealing. They resist warping, cracking, and water infiltration, making them ideal for both older GTA homes and new construction builds.

Secure Locking Mechanisms

We install reinforced cam-action locks for maximum sash security and weather sealing. These locks prevent prying and improve thermal tightness, giving homeowners peace of mind and keeping GTA homes safe and energy efficient.

Custom Sizes, Colours & Grilles

Choose from a wide range of frame colours, grille styles, and hardware finishes to suit any home design. All units are custom-made to exact dimensions for a perfect fit, ideal for retrofit, renovation, or architectural preservation projects.

CSA-Tested for Canadian Climate Durability

Our windows are certified by the CSA Group for thermal performance, water resistance, and structural integrity in Canadian weather. Built to endure GTA’s snow loads, wind exposure, and fluctuating temperatures, all year long.

Benefits of Replacing Single-Hung Windows in Your GTA Home

Replacing old single-hung windows improves efficiency, comfort, and home value, while cutting long-term costs for GTA homeowners. All benefits of the single-hung windows are:

Single-hung windows are more affordable to replace than double-hung units due to their simpler sash design and fewer moving parts. Our GTA installations maximize performance without inflating costs, making them a budget-friendly upgrade that delivers lasting value.

Our Low-E, Argon-filled glass units and fusion-welded vinyl frames reduce air leakage and thermal transfer. GTA homeowners save on heating in the winter and cooling in the summer, lowering monthly energy bills while improving overall indoor comfort.

The vertical sliding sash doesn’t swing outward, making single-hung windows ideal for walkways, patios, and compact spaces. This smart design maximizes airflow while saving square footage, offering a practical solution for GTA homes of any size.

With custom grille patterns, frame colours, and hardware finishes, our single-hung windows blend seamlessly into any property, whether you own a modern GTA condo or a century-old Toronto heritage home. Timeless style, without sacrificing performance.

Our double or triple-pane insulated glass units minimize outside noise, making your home quieter and more peaceful. Combined with weatherstripping and secure seals, this feature is especially valuable for GTA homes near busy streets or transit lines.

CSA-tested for Canadian conditions, our single-hung windows resist warping, condensation, and water infiltration. From icy winters to humid summers, they deliver consistent performance year after year, outlasting builder-grade or outdated wood models.

Replacing old single-hung windows improves temperature consistency, reduces drafts, and increases curb appeal. Energy-efficient upgrades backed by CSA certification not only make living more comfortable but also enhance resale value for GTA homeowners.
