Are casement windows good for Long Island's coastal weather?

Casement windows are one of the best choices for coastal Long Island homes. The compression seal on all four sides creates the tightest closure of any operable window, which is critical for blocking wind-driven rain and salt air. When closed, the sash actually presses harder against the frame as wind pressure increases, making them more secure in storms.

Can I use casement windows to replace double-hung windows?

Yes. We frequently replace old double-hung windows with casement windows, especially in kitchens and bathrooms. The rough opening dimensions are adjusted during installation. Casement windows can be installed in the same opening size, though the operating style and look will change.

Do casement windows have screens?

Yes. Casement windows use interior-mounted retractable or fixed screens. Since the sash opens outward, the screen sits on the inside of the window. Many models feature a fold-down crank handle that stays clear of the screen when the window is closed.

How do I clean the outside of casement windows?

Most quality casement windows feature a hinge system that allows the sash to open far enough for you to reach the exterior glass from inside your home. Some models have a detachable sash for even easier cleaning. No ladders needed for standard first and second floor installations.

What is the price difference between casement and double-hung windows?

Casement windows typically cost $50-$150 more per window than comparable double-hung windows. The additional cost comes from the multi-point locking hardware and crank mechanism. However, many homeowners find the superior energy efficiency and ventilation worth the premium.

Casement Window Replacement on Long Island

Casement windows crank open outward on a hinge, providing the tightest seal of any operable window style. The compression seal engages on all four sides when closed, making casements the top choice for energy efficiency and weather resistance. They are ideal for hard-to-reach locations like above kitchen sinks, behind countertops, and in bathrooms where you want maximum ventilation without sacrificing security.

Key Benefits

Why Choose Casement Windows?

Tightest Seal Available

The sash presses against the frame on all four sides with a compression seal, creating the most airtight closure of any operable window. Ideal for Long Island's coastal wind exposure.

Maximum Ventilation

Casement sashes open a full 90 degrees, catching side breezes and directing them into your home. You get 100% of the window opening for airflow, compared to only 50% with double-hung windows.

Enhanced Security

Multi-point locking hardware embeds the lock bolt into the frame at multiple points. Casement windows are among the most difficult window styles for intruders to force open.

Unobstructed Views

With no center rail dividing the glass, casement windows provide a clean, unobstructed sightline. Pair two or three together for a wall of glass effect.

Perfect Above Sinks & Counters

The crank handle lets you open and close the window without leaning over countertops or reaching across sinks. A folding handle stays flush for easy screen operation.

Energy Star Certified

Low-E double-pane glass with argon gas fill and the compression seal combine to deliver excellent energy performance, often outperforming double-hung windows of the same size.

What Long Island Homeowners Say

Replaced all the kitchen and bathroom windows with casement windows. The difference in airflow is incredible — one window open and the whole room ventilates. The crank operation is smooth and the seal is so tight we can feel the temperature difference.

We live near the south shore and needed windows that could handle the wind. WCLI recommended casement windows and they were right. Through two nor'easters, not a single leak or draft. Professional installation and great follow-up service.

David K.

Massapequa, NY

The crew installed 8 casement windows in our colonial and the quality is outstanding. Love the unobstructed glass — so much more light compared to our old double-hung windows. James and his team really know their stuff.
