Window Types We Install & Replace

Apex Window Werks offers a wide selection of window styles and types to fit your needs and preferences. Although our expertise is not limited to these, here’s some helpful information about the most common windows we repair and install.

European Tilt & Turn Windows

European classic, tilt & turn windows are inswing windows with a double function. With a turn of the handle, they either tilt or swing in. The tilt function provides secure ventilation while maintaining beautiful views.

Single-Hung Windows

Single-hung windows consist of two sashes, with the bottom sash being moveable and the top sash being fixed. The moveable bottom sash slides up and down while the top sash remains stationary.

Double-Hung Windows

Double-hung windows have two sashes that open and close vertically. They have two panels, an upper and a lower, which slide up and down and tilt inward for easy cleaning.

Picture windows

Picture windows are large, non-opening windows with a single, large pane of glass that allow natural light to enter a room. They are usually installed in places with great views to create the illusion of a larger space.

Casement Windows

Casement windows are hinged windows that open outward from the side. They are typically opened and closed with a hand crank mechanism but can also be motorized.

<span class="white">Words</span> from<br>Our Clients

Words from
Our Clients

Service technicians were polite, and professional. They removed damaged parts of the window, cut new pieces to fit, stained the wood and installed them nicely. The team cleaned up as if they were never there. I would recommend Apex Window Works for your window repair.

Glenn Kaupert

Two windows in my house were cracked for a few years. The crack started to get worse on one of them, so it was time to get the glass replaced. The estimate was fair and when the crew came out to replace the glass, they were clean and neat and made sure it was done correctly. I would use them again if a future need arises.

Pete Nowicki

Very kind people. Respectful of our property. Such a cold weather day they worked & didn’t complain’. And Price was much more reasonable than replacing the whole bow picture window. One of the workers personally dropped off a needed window crank piece & installed it the next day. Highly recommend.
