"They cleaned our 8 Pane windows on our two story 1940â  s house perfectly with the exception of one window which it seems they forgot and I missed when I inspected before they left. The guy that came out was professional and did great work. He stuck with our original quoted price even though upon arrival he realized that this was an old house me with multi pane windows and outdoor storm windows on each. Windows looks ok great and I will give a second review after I hear back on the missed window from the company"

Now Joe and his professional crew have replaced all our windows . There are never surprises or additions from when the job is quoted. Once again we are totally satisfied and delighted with their work!! It has been a stress free experience each and every time."

Windows questions, answered by experts

The type of casement window you have depends on where the hinges are located, the number of sashes, the style, and how the windows open. Single casement windows are popular casement windows that use a handle or crank to open. If you have two casement windows side by side, you likely have double casement windows. 

Windows that swing inward can tip you off to having in-swing casement windows, while windows that open from the bottom and swing outwards are top-hinged. If you can open your windows by pushing them outwards like a door, you may have a type of push-out window.

Contrary to popular belief, wavy glass in older homes isn't caused by warping. The blowing technique used to create windows in homes dating back to the 1700s, 1800s, and early 1900s left behind small bubbles that create a wavy effect. If a glass window is functional, there's no need to consider wavy glass damaged. In fact, many homeowners prefer the old charm of wavy glass.

The maximum protruding distance allowed for a bay window is determined by its flank angles. 30-degree flanks can extend about 13 to 14 inches. If the angle is 45 degrees or larger, then the bay window can stick out about 19 inches. If the window extends too far out, it would cause structural instability and safety concerns.

Egress windows are typically required for basements with habitable space or living quarters. Not all basements or lower levels require egress windows. However, egress windows are required in homes with living spaces such as bedrooms and living rooms in a basement. The International Residential Code and International Building Code require sleeping rooms to have a specific size egress window. Check your local building codes to confirm the requirements in your area.

Picture windows are still in style, even though they are one of the oldest types of windows. Other windows, like single- or double-hung windows and casement windows, have increased in popularity because they can open up for fresh air. However, homeowners still love the way a picture window can frame their lush outdoor garden or other pleasant neighborhood views.
