Why Choose Casement Windows?
Maximum Ventilation
Crank-out design opens the full window area to catch breezes — up to 5x more airflow than sliding windows.
Superior Seal
The sash presses against the frame when closed, creating one of the tightest seals of any window type — critical for CT winters.
Best Energy Efficiency
Compression seal design gives casement windows the highest energy ratings of any operable window style.
Enhanced Security
Hook-shaped locks embedded in the frame make casement windows extremely difficult to force open from outside.

Casement Window Installation in Connecticut
Casement windows have surged in popularity among Connecticut homeowners for one simple reason: they provide the best energy efficiency of any operable window. The crank mechanism pulls the sash tight against the frame, creating a compression seal that virtually eliminates air infiltration.
For Connecticut's harsh winters, this matters enormously. While sliding and double-hung windows rely on weatherstripping that can wear over time, casement windows actually seal tighter as wind pressure increases. The stronger the winter wind blows, the tighter the seal becomes.
At 203 Windows, we install casement windows from premium manufacturers including Andersen, Pella, and Marvin. Every installation includes proper shimming, insulation, and flashing to meet Connecticut building codes and our exacting quality standards.
Casement Windows FAQ
How much do casement windows cost in Connecticut?
Casement window replacement in Connecticut typically costs $400–$1,000 per window installed, depending on size, material, and glass package. Vinyl casements are most affordable at $400–$650, while fiberglass and wood options range from $600–$1,000+. All prices include professional installation.
Are casement windows better than double hung for Connecticut?
Casement windows provide a tighter seal and better energy efficiency than double hung windows, making them excellent for Connecticut's cold winters. However, double hung windows are more versatile, easier to clean on upper floors (tilt-in sashes), and have a traditional look that suits most CT home styles. Many homeowners use a mix of both.
Do casement windows leak in heavy rain?
No — properly installed casement windows are actually more rain-resistant than most window types. The sash presses tightly against the weatherstripping when closed, and the top of the window acts as a small awning when partially open. Our Connecticut installation includes proper flashing and sealant for full weather protection.
Can I replace my double hung windows with casement windows?
Yes, you can switch from double hung to casement windows in most cases. The opening may need minor modifications, and the exterior trim style will change slightly. We handle all framing adjustments and ensure the installation meets Connecticut building codes.
