Casement Windows
in McLean, VA

Casement windows are a great option for homeowners who are looking for an alternative to traditional window units.

As the name implies, they open on the side and are operated by crank or lever. In addition to offering superior ventilation, they are also very energy efficient, reducing energy costs and helping people live more sustainably. Casement windows are a great choice for those who want to keep their homes secure. The high level of security that they provide is one of the most important benefits of this type of window.

One of the most important facts about casement windows is the safety aspect. Because they have fewer moving parts, casement windows are harder to break. Because they cannot be unlocked from the outside, burglars would have to smash the windows several times to get them open. Besides being easy to operate, casement windows are a great choice for children's bedrooms. They are easier to access from hard-to-reach locations.

Frequently Asked Questions About Casement Windows

How do casement windows differ from other window styles?

Casement windows open outward using a crank mechanism, similar to how a door swings open. Unlike double-hung windows that slide up and down or sliding windows that move horizontally, casement windows provide a full opening from top to bottom. This design creates better ventilation and unobstructed views when open, plus a tighter seal when closed.

Will casement windows work in my McLean home?

Absolutely! Casement windows adapt to virtually any home style in McLean, from traditional colonials to contemporary designs. They work particularly well in spaces where you want maximum ventilation or in hard-to-reach areas like over kitchen sinks. Many McLean homeowners install them on sides of the house facing prevailing breezes to capture natural air circulation.

How long do quality casement windows last?

With proper care, our casement windows typically last 20-30 years. McLean's climate can be demanding on windows, but our high-quality materials stand up to humidity, temperature fluctuations, and UV exposure. The hardware (hinges and crank mechanisms) may need occasional lubrication but is designed for decades of smooth operation.

Are casement windows energy efficient for Virginia weather?

They're actually among the most energy-efficient window styles for our McLean climate. When closed, casement windows press against the frame to create an exceptionally tight seal that prevents air leakage during both hot summers and cold winters. Combined with our energy-efficient glass options, they significantly reduce heating and cooling costs year-round.

Can casement windows be cleaned easily?

Cleaning casement windows ranks among their biggest advantages for McLean homeowners. Because they open fully outward, you can easily reach the exterior glass from inside your home—no ladder climbing required. This makes seasonal cleaning much simpler, especially for second-floor windows.

Are casement windows secure?

Casement windows offer excellent security. Their hook-shaped locking mechanisms embed into the frame at multiple points when closed, making them very difficult to force open from outside. Unlike sliding windows that can sometimes be lifted from their tracks, casement windows stay firmly anchored when locked.

Do casement windows require more maintenance than other styles?

Not significantly. The moving parts (hinges and cranks) benefit from occasional lubrication—about once a year is typically sufficient. Our vinyl and fiberglass options require virtually no maintenance beyond normal cleaning. Wood casement windows may need refinishing every few years, depending on sun exposure, but our factory finishes extend this timeline considerably.

What size limitations exist for casement windows?

While casement windows offer flexibility, extremely large sizes may require additional support due to the weight of the sash when open. For very wide openings, we often recommend installing two casement windows side by side rather than one oversized unit. During your free estimate, we'll measure your openings and recommend the optimal configuration.

How long does installation take?

For most McLean homes, we typically complete casement window installation in just one day, causing minimal disruption to your routine. Larger projects or those involving custom elements may take longer. Our installers take care to protect your home's interior and exterior during the entire process.
