"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."

"Paul and his team were great. We replaced most of our windows as well as an old wooden window. We were concerned that the replacement for the wooden window wouldn’t come out as nicely but the replacement was beautiful! We are looking forward to our electric bill this summer."

"Wow! From start to finish, A Clear View was fantastic to work with. We never had to have our windows cleaned before and so I went into the process not knowing much. My experience started with Carlie contacting us within hours from our search and helping to quote our project. She worked with me on pricing and understanding everything. Finally window cleaning day came and it was like Christmas. I was so excited. Jordan arrived at 7:30 AM and he worked non stop, quietly, perfectly cleaning all our windows until 5:30 PM that night. I had asked for inside, outside, screens and sills to be cleaned. He was fantastic. Our windows look absolutely amazing. He also was very attentive to my husbands work schedule and when he could clean the office windows and worked around his schedule for those windows. Meaning, he couldn’t clean those in the order he probably wanted to, but was super accommodating about it. Again, he was quiet, polite, understanding to the chaos with all our pets and lastly, never spilled a drop or any water. He had a large bucket that he would fill with hot water and his solutions and used our utility sinks for filling and dumping and there was nothing wet, spilled or splashed. Much better than anything I could have ever done. We are very please and highly recommend. And I will 100% be calling to have them come back next year around the same time! The best part…every year for Thanksgiving we gather for a mid day Thanksgiving meal with all the family. We can watch the sun set from our dining room. Every year I would say, “Well, it would be a much prettier sunset with clean windows!” My dream just came true!!!!!!! Thank you A Clear View Window Cleaning. Start to finish it was an enjoyable process."

"Team from Power completed the work on time and cleaned up well after work was completed. Windows were measured correctly so replacement windows fit perfectly and were quality Pella windows versus no-name windows offered by other vendors."

Windows FAQs, answered by experts

Using plastic shrink film over the window will cut down on drafts, which makes the air inside your home feel warmer. Plastic shrink film doesn’t quite have the insulative properties of a new window or of adding insulation inside the window jamb, but it will help. Plus, it’s a cost-effective solution to keeping your home warmer.

If you don't have hurricane shutters or impact-resistant windows, boarding up windows before a hurricane is worth it. According to the Federal Alliance for Safe Homes, protection is essential for all your home's entry points, including windows, doors, skylights, and garage doors.  

When windows break, wind enters your home, creating enough pressure that could cause the weakest part of your to rupture. Often, the weakest part is the roof, which can "pop" off of a home in a hurricane. The simple act of boarding up your windows can protect the structural integrity of your house.

Window replacement is typically always worth the cost, both from a money-saving standpoint and a comfort standpoint. If your windows are older and significantly damaged, a window replacement can actually save you money in the long term by improving energy efficiency. If your windows aren’t up to code, you may not really have a choice. 

The purpose of an awning window is to let fresh air into your home without taking up too much wall space. They’re ideal if you live somewhere that gets a lot of rain because their design helps prevent rain from coming into your home. In bathrooms, awning windows also help with ventilation but don’t compromise your privacy.

Impact windows can last between 10 and 40 years, depending on how much wear and tear they receive. This is roughly within the range for standard windows; standard windows tend to last between 15 and 50 years. You can extend your windows’ lifespans by performing regular maintenance on them and ensuring they are installed correctly.
