"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."

"I was very happy with response from Eddis. He gave me a quote upfront and followed it up with an invoice via email. I paid him half at the beginning and another half when he came back to install the window. He was very professional and respectful of my house. I will definitely use A.R. Glass again if I have window repair needs."

"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."

"The Premier Windows and Glass has provided an excellent service for me! A frame of one of the windows in my condo was broken, and I looked for a company that would fix it and prolong the life of the window. So, I was very happy to discover The Premier Windows and Glass. Their technician was very polite, professional, and knowledgeable. Not only did he do a quality job on fixing the frame, but he also explained to me what needs to be done to prevent the window from breaking down again and avoid paying a lot of money for its replacement. In addition, the manager and technician responded to my service request in a prompt manner. The problem was solved on the day when I called the company. Last but not least, the company offers competitive service rates and does not push people to spend more money than is absolutely necessary. I would strongly recommend this company to anyone who needs to have a window fixed or replaced."

Windows FAQs, answered by experts

The amount of time window lintels last is based on the environment they’re installed in and the material that’s installed. For example, a steel lintel installed in a temperate climate will always last longer than a wooden or brick lintel installed in an area with tons of rain, snow, and wind. No matter which material you choose or where you live, proper maintenance will ensure your lintels last as long as possible.

Well water can leave ugly marks on your window. A vinegar-water spray will remove most well water stains from your windows. However, you can also use a baking soda paste if the stain is too stubborn. Consider applying waterproofing protection to the glass surface after cleaning for long-term protection. A protective film or spray layer also makes it easier to remove the water stains next time.

Windows with muntins are slightly more expensive because you’re paying for more material, but the cost shouldn't be that much higher since most muntins are fake on modern windows. You’re looking at a cost between $25 and $100 more per window for muntins, depending on the type. The only exception is if you want custom muntins to match your home style or meet your personal preference. Most manufacturers will charge more for these as they can’t mass-produce them. Windows with true muntins are rare, and they’re much more expensive upfront and over time if you ever need individual glass replacement.

Adding windows to a house is expensive. Budget roughly $5,800 to add a single window, and double or triple that to add two or three. In some cases, adding a single window can exceed $20,000, depending on the type of exterior wall, the size of the window, the type of window, local permit costs, and other factors.

Egress windows are typically required for basements with habitable space or living quarters. Not all basements or lower levels require egress windows. However, egress windows are required in homes with living spaces such as bedrooms and living rooms in a basement. The International Residential Code and International Building Code require sleeping rooms to have a specific size egress window. Check your local building codes to confirm the requirements in your area.
