"This is our second "phase" of window replacement and we used Zen Windows once again. High quality products, excellent service, and the install was once again flawless. Plus no dealing with salespersons selling marked up windows, then playing pricing games which still cost more. It's a pleasure to work with Scott and Zen Windows."

"I am very fussy and frequently critical, yet I have only the best things to say about Unicorp window replacement. The owner came to my home - on time - to explain all the options and costs for replacing my windows. It didn't feel like a sales pitch, but more like a discussion of what was best for my home. Unicorp is a local company and makes their own windows, so I knew if there was a problem, there would be someone nearby to call. My windows were installed on time and the crew was very professional. They are very hard workers; they didn't even take a lunch break. I was assured that my new windows would not let the cold air in, as my old windows did. I'll have to wait for winter to test this out, but I have confidence that since these windows were custom-made for me, they fit more tightly. It has been a pleasure to find a local company that has an excellent product, is honest, and reasonably priced."

"Excellent work. The person who assisted us was gruff and no-nonsense, but professional. He asked that we send a photo of the window, which we did. He then came out and measured the window. He came back a couple of days later, and completed the work. The window looks fantastic, and we are very pleased with his work."

"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."

"It went very well considering the weather did not cooperate. Pete's crew came promptly at the time scheduled to do the power washing and clean the gutters even though we were experiencing light rain showers. They did an excellent job. They even power washed the mailbox post even though it was not part of the work requested. Because it was raining and the deck needed to dry before applying stain, the windows and stain application were scheduled for 3 days later. Again, Pete and a crew showed up that Saturday at 8am and worked until 6pm. He also used a moisture meter to make sure deck was dry enough to stain (there had been a brief light shower the day before). We have a very large deck, so they were not able to complete everything. Pete returned the following Tuesday to finish staining, repair the lattice and water proof the wood along the walkway. There was a small section of grass that somehow had been damaged when the crew was applying the stain. Pete went home where he happened to have some sod and brought enough to repair and cover this section of the lawn. Through the entire process, he was very proactive with phone calls and emails and responsive to all questions and inquiries regarding the work. His crew was polite and worked hard. I very pleased with the results."

Windows questions, answered by experts

ENERGY STAR®-certified windows are the most energy-efficient windows on the market. This certification means that the window meets strict efficiency guidelines set forth by the Environmental Protection Agency. While they might cost more upfront, they can save you money on your energy bills in the long run. ENERGY STAR®-certified windows lower household energy bills by an average of 12% annually.

In short, it depends. After 20 years, the glass in your windows is less energy efficient, which can cause increased electricity bills. You might also see signs of water damage or natural wear and tear over the years. However, with proper maintenance, some window frames can last up to 50 years, so you may only need to replace the glass to save on energy. 

At the same time, window replacement is a major investment, so replacing the glass in rooms most impacted by outdoor temperatures is one way to avoid going all-in to replace your windows.

Most windows last between 15 and 30 years. The exact life span depends on a few things, including the frame material, the quality and type of glass, the weather in your area, whether or not the window is installed properly, and more. You can always speak with a window professional about whether or not it’s time to replace your windows or if repairs would be more affordable. You’ll need to consider the cost of replacing your windows, the cost of repair, and the longevity of each solution.

When you need new windows depends on a variety of factors, including the age of your windows, the age of your home, and the climate you live in. If you’re dealing with budget constraints, you don’t need to replace all your windows simultaneously. 

When buying new windows, you should consider energy efficiency, safety, and aesthetics to choose the right window for you.

Removing a window isn’t a very long process. Depending on several factors, it can take anywhere from 20 minutes to upwards of an hour. The size of the window greatly impacts the time it takes to replace it. Accessibility is another big component. If it’s hard to reach the window or reaching it is dangerous, anticipate it taking longer. 

Lastly, if the old window is in poor condition, it could take longer to remove it safely—especially if the frame has wood rot and is structurally unsound.
