"Our 87 unit 3 story coop brick apartment building had 30+ year old windows and terrace doors needing replacement. Aside from judging the quality and design of various window vendors, we wanted the scheduling and installation to be coordinated by the vendor with minimal drain on building management and maintenance personnel. We were impressed with the window design, specs, lifetime warranty and dealing directly with the manufacturer. Scheduling was flexible and installation went smoothly. The installers were efficient, neat (careful, drop cloths, vacuuming) and courteous. The sales and office staff were helpful and easy to deal with. Shareholder feedback has been very positive. Would highly recommend. - Submitted by Coop Board President"

Windows questions, answered by experts

Depending on size, material, and labor, two windows can cost between $600 and $1,600.

Yes, you can create a solution of dish soap and hot water to create a cleaning solution. You’ll want to mix about one to two drops of dish soap for every 8 ounces of hot water. If you use too much soap, it’ll create too many suds and make it harder to effectively wash away.

Yes, triple-pane windows are more resistant to condensation. They help to reduce interior condensation that forms as a result of warmer temperatures inside your home than outside it. This makes them a good fit for cooler climates, particularly with newer, well-sealed homes that retain higher levels of moisture in the winter months.

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.

Yes, triple-pane glass windows cost more than double or single-pane windows. You’ll eventually get that money back in energy savings. Depending on how much you pay for the installation, you could recoup your costs in 10 to 20 years. Triple-pane windows have extra layers of glass, which improve insulation and help save money in long-term heating and cooling costs.
