"We had Window World replace 36 windows in our home.  The entire house including the basement windows.  
These guys are so amazing!  They did the entire job in 3 days.  The old windows were original to our 1918 house, which can be a little complicated.  The replacement windows are vinyl, and a number of them needed to match our interior wood trim.  The window mullions very closely match the old windows.  They are double hung and have all the great features that can be that Window World offers.  
New windows are probably one of the best in vestments in our home.   We could not be happier and I would happily recommend them to anyone.

"Great customer service they arrived on SAID time ON time. They didn't leave until the job was completed. I spotted one small flaw but nothing to complain about other than that they did a great job. They cleaned up behind themselves. I had to disposed of all the trash myself but they did put all the trash in bags and sat them outside nice and neat and it was also in the contract that the customer is responsible for disposal of trash. It was not a surprise. This properly why the cost was reasonably priced. I will use them again."

Windows FAQs, answered by experts

Depending on the window style and your home's layout, you can install replacement windows from either the inside or the outside. Many installations are done from the inside because it allows for better access and weather protection, but some exterior installs are easier for certain types of siding or trim. The key is choosing the approach that gives you the best access to the frame while keeping the existing structure intact.

Look for stickers at the top or inside of the frame, like in the tracks when the window is open. Some brands also stamp their name onto the frame itself or place it between the panes of glass, although this is less common. If you can’t find the info on the window itself, consider asking your neighbors or HOA.

The differences between a bay window versus a bow window involve the number of individual windows and the angle at which both windows extend from the home. A bow window has four to six individual windows that form a curve outside the exterior wall. A bay window usually has two small windows on the edges that angle outward from the exterior wall and a large window in the middle that’s parallel to the home’s exterior wall.

The disadvantages of putting plastic over your windows are that they are time-consuming to install and don’t always have the aesthetic that you may be looking for. The plastic is lightweight and not at all sturdy, so if you have kids or pets, the plastic can rip easily, meaning you’ll need to replace it often. It also doesn’t allow for the freedom of window movement that window film or shades offer. The single advantage that plastic window coverings have is that they are inexpensive and can be simple to install.

Yes, you can replace the frame around a window by completing either a partial replacement or a full replacement. With a partial replacement, your window specialist will remove the trim around the window and replace or repair just the damaged portion. For a full replacement, your tech will need to remove the window, replace the frame, and then reinstall the window.
