"Ray the owner was on time, worked fast and did a great job. Our house will sell better because of our sparkling windows. He was friendly and even washed the two little windows on our shed for no charge that were not included in the bid.Our bid also included cleaning out our window wells and cleaning those windows. He did an excellent job. His prices are low. He is a veteran and hires veterans in his business. I would definitely recommend this company for windows and gutter cleaning."

Windows FAQs, answered by experts

A garden window is about 16 inches to 24 inches deep. This extra space makes room for small potted plants, which is how the garden window, also called a greenhouse window, got its name. Because garden windows jut outward from the house, they need to be installed in a place where they won’t obstruct walkways.

Yes, you can use glass cleaner on outside windows, but only after you’ve rinsed away as much debris as possible. Using glass cleaner on top of a layer of dirt will only make it harder to clean. 

Casement windows can either be left or right opening, and every window manufacturer makes both so that you can choose which works best for your space. In many cases, you’ll want one left-opening and one right-opening casement window to sit on either side of a picture window or to act as the side panels in a bay window. Just remember that the direction is described from the curb. An FCL (from the curb left) hinges out to the left if you’re looking at the exterior of your home, and an FCR (from the curb right) hinges out to the right.

You can add any type of window to a brick house, so long as the window has proper support. Windows with wider openings and windows in brick walls will need a lintel to support the extra weight above the window frame. A lintel is a support beam that distributes the weight from above evenly around the window.

The key difference between a hung window and an awning window is that hung windows (including single-hung and double-hung versions) slide vertically to open and close. In contrast, awning windows have a hinge at the top and open outward at an angle. You can use both types of windows throughout your home, but awning windows are best suited for kitchens and bathrooms.
