"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 questions, answered by experts

Yes, egress windows can significantly add value to a home. By making basement and attic areas safer and more livable, they allow you to market these spaces as finished living areas, which increases your property's value. Many homeowners can recover the full installation cost, with some sources citing a return on investment of around 70%. The exact value added depends on your specific home, location, and adherence to local building codes. Beyond financial value, egress windows enhance functionality by adding natural light and comfort. They are also a crucial safety feature, often mandated by building codes to serve as an emergency exit.

Typically, a bay window is, at minimum, 42 inches wide. That said, you can always design a custom bay window that is smaller—box bay windows are usually less than three feet in width and are ideal for smaller spaces.

Removing a window isn’t a very long process. Depending on several factors, it can take anywhere from 20 minutes to upwards of an hour. The size of the window greatly impacts the time it takes to replace it. Accessibility is another big component. If it’s hard to reach the window or reaching it is dangerous, anticipate it taking longer. 

Lastly, if the old window is in poor condition, it could take longer to remove it safely—especially if the frame has wood rot and is structurally unsound.

The material around a window is simply called the window frame, but the individual pieces also have different names. The top portion of the frame is called the head, the side pieces are called jambs, and the bottom portion is called the sill. If you have multiple windows next to each other, you’ll also have a mullion, which is the frame piece that separates the individual windows. Windows stacked on top of each other are separated by a horizontal frame piece, which is called a transom.

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.
