"Kenny and team were amazing to work with - professional, polite, honest, and finished the project ahead of schedule and at a very fair price. We had two old single pane windows replaced in our basement (which may have been 50+ years old), and a new window well installed. The work was very well done. I have since recommended Clifton to multiple friends and other contractors. Five stars."

"We just had Unicorp install new windows throughout our entire house. The window quality is excellent and the installation went very well. We were replacing 55 years old windows - and were very happy with the entire process, from selection, exterior color choices, and finally installation."

"All went well. The gentleman who was doing the cleaning arrived on time, reviewed everything that was to be done and updated the quote to reflect the total number of windows involved. I also asked that he clean the window sills. He started the cleaning and completed the work in less than 3 hours. All nicely done."

Windows questions, answered by experts

If your windows weren’t manufactured with a retaining clip to receive muntins and hold them in place, you should contact a window company near you to add them for you. A professional will bond the muntins directly to the glass to hold them in place, and they’ll make sure the edges line up nicely with your window frames. If your window does have retaining clips to hold muntins in place, you can just pop the muntins into the clips.

Bay windows are expensive mostly because their above-average size means higher material costs. Unlike bow windows, most bay windows also include casement windows on either side of a picture window, and the opening mechanisms for casement windows drive up costs. You’ll also pay higher labor costs to install a bay window, as you’ll often need multiple technicians to lift the window into place.

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.

Window capping costs between $1 and $2 per linear foot. Since your average window size is 24 by 36 inches, you’re looking at 10 linear feet in total, or $10 to $20 per window. Labor adds another $30 to $100 per hour to the project. If you have custom windows, you’ll spend more to have your windows capped. Fiberglass tends to cost more than vinyl and aluminum, while vinyl costs the least but has the shortest lifespan and may have a higher long term cost.

No, it isn’t necessary to have energy-efficient windows. However, if you care about your energy bill and making your windows more energy efficient, fixing any heat, UV, or air transfer issues is an excellent way to lower your bills and keep your house cooler in the summer and warmer in the winter.
