"From start to finish, Steve was a dream to work with. First, he educated us on the different kinds of films to put on our new windows. He left us with three different patches of film on our window for a week so we can make a decision based on what kind of light and how it looks with different weather patterns. During the installation process Steve was a professional. Explained the entire process step by step. He was efficient, kind, and informative. His price was fair, his work and performance were off the charts, and above all, he was just a great guy. We are grateful we found him and our new home looks better than before!"

"I liked that there was no nonsense. Their salesman was straightforward and the price was fair. We were also impressed with the installers. They installed all the windows in 1 day and they look great. I'm happy I chose them."

"I contacted 14 contractors over the course of 2 and 1/2 years to replace and paint exterior trim that was causing leaking into our unit and the unit below. No one else would take the job due to the degree of difficulty. They had to do the work on the back of the building using 60 foot ladder and 50 foot on the front of the building in frigid weather during late December and early January. It was not cheap, but reasonable due to the conditions to take on the job. They not only replaced and painted all trim where necessary, but prepped and painted all the trim on the back of the building and some extra on the front at no extra charge. Very pleased."

Windows FAQs, answered by experts

Typically, triple-pane windows made with krypton gas filling are the most energy efficient. A window’s frame, glass, design, and installation all affect its energy efficiency. These windows, in particular, are designed highly effectively in terms of their ability to insulate.

Consider adding sash locks to your windows to fix drafty windows if you don't currently have any. Sash locks in double-hung and single-hung windows help to create a tight seal when windows are shut.

Storm windows are placed outside of already-installed windows. Regular windows are installed into a frame, offering a barrier to the elements but no special protection. Storm windows add extra protection to regular windows, reduce noise, and improve insulation. Replacing a regular window involves a different process than installing a storm window. 

Vinyl windows have a few cons to consider before installing. For instance, while vinyl windows are energy efficient in terms of maintaining your home’s temperature, the actual process of making vinyl windows involves chemicals that are harmful for the environment. Vinyl windows are also less customizable than some other types of windows.

Bifold windows work by using a track that allows panels to slide to the side and "stack" so they take up minimal space, leaving the largest opening. The sashes connect to each other with butt hinges or concealed hinges and to the window frame with the same type of hinges you’d find on a casement window. Some manual bifold windows also have casement stays or another piece of hardware to keep your windows in place when they’re open.
