"Zen Windows advertises that they make things easy, and that they do. Zen windows doesn’t just make things easy, they have quality products, reasonable prices and exceptional service. We just had an entry door replaced and everyone we worked with was great. While they don’t push you into buying any products, they do go out of the way to help you make the right decisions. Everything went exactly as they told us, the installers were top notch and the finished product looks great. Without hesitation, we would highly recommend Zen Windows to anyone looking for doors or windows."

"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."

"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."

Windows questions, answered by experts

Yes, it is generally better and more cost-effective to replace all your windows at once. Contractors often lower the per-window labor and material costs for larger projects, saving you money in the long run. Installers may also quote a flat rate for overhead, making multiple small jobs more expensive than one large one.

Replacing all windows simultaneously offers other advantages:

  • Aesthetics and Home Value: It creates a cohesive style and uniform energy efficiency, which is appealing to potential home buyers.

  • Efficiency: The entire replacement process, which can take several weeks, is completed in a single, more efficient project.

However, replacing all windows requires a significant upfront investment. While you can replace just a few windows, experts recommend replacing at least five to eight at a time to avoid high overhead costs. An exception is when a single window is damaged; in that case, it can be replaced on its own.

Yes, window manufacturers and installers can mull together three windows—or even more—for a more impressive appearance that lets maximum natural light into your home. However, you may have constraints regarding the total size of the wall opening. Your installer can help you determine what size wall opening is safe based on the structural load. In most cases, you can install additional supports to span the opening, like a steel I-beam, but this drastically increases the installation cost.

Sometimes, you can buy windows directly from the manufacturer, and it may be cheaper than buying through a third party or wholesaler. Manufacturers may also offer more options, including custom shapes and features, or better warranties if you purchase through them directly. 

However, some companies limit the ability to buy from them, especially if you need standard pre-fabricated sizes, so don’t expect this service from every manufacturer.

Bifold windows work by using a track that allows panels to slide to the side and "stack" so they take up minimal space, leaving the largest opening. The sashes connect to each other with butt hinges or concealed hinges and to the window frame with the same type of hinges you’d find on a casement window. Some manual bifold windows also have casement stays or another piece of hardware to keep your windows in place when they’re open.

You should avoid using abrasive materials and harsh chemicals when cleaning windows. Abrasive tools like scrubbing pads, rough cloths, or steel wool can permanently scratch and damage the glass. Harsh chemical cleaners containing alcohol or ammonia can damage window treatments, frame materials, and special features like tinting. It is also best to use distilled or filtered water instead of hard water, which can leave spots or streaks. For best results, use a clean microfiber cloth to wash the glass and old black and white newspapers to dry it without leaving streaks.
