Need to replace a bunch of windows. Mark came out and explained everything. Walked us through the process and wasnt the pushy salesman you usually deal with. Crew was great and professional. Followed up afterwards to ensure everything was going well

Got a quote last week. Sales representative was excellent. Great product knowledge. Products offered seemed very good. Prices seemed fair. Before you buy, it’s worth the time to hear and see what they have to offer. I didn’t purchase the windows quoted because turn around time was outside of my timeframe for the job quoted, but I’m most likely going to purchase windows from them on my next build in 2024. The sliding doors are very impressive. Check them out.

Window Perfections is the BEST window company to work with from start to finish! Highly recommend them!!They have a great product and have an absolutely great team to work with! It started with Caleb, he was very professional, courteous and knowledgeable. We then worked with Bonnie, who did a great job on getting us scheduled in a timely fashion. Lastly the installers, Brian and Kenny, did an awesome job. They wouldn't even come in our home with their shoes on until they had placed drop cloths down everywhere. The installation only took a few hours, but afterward, you wouldn't have even known they were here. They cleaned up so well that there wasn't dust or debris found anywhere (inside or outside)!I'm telling you, Mark has a wonderful staff working for him and a great product. We are DEFINITELY looking forward to working with them in the future to replace the rest of our windows!

My husband and I decided to use this company based on the quality of the windows and after speaking to Mark, we were confident that this company would do a great job with installing all new windows and two sliding doors. We were very satisfied with the work that Brian, Buck, Josh, and Kenny did. They were always on time and cleaned up every day. They were very professional, trustworthy, and did an awesome job. We are very satisfied with this company and the work that was done.

I would HIGHLY recommend Window Perfections to anyone considering window replacement or new windows for their home. The quality of the windows they handle (OKNA) is very very good, the amount of options on type, color, and configuration is great, and I cannot say enough about how clean, neat, polite, and professional the installation crew is. Not to mention, Mark is a very honest guy and extremely customer focused.We obtained three other quotes before choosing Window Perfections, and it was just as clear as their windows that we made the right choice. They by far had the best value to offer. So if you're looking for a high quality product that is provided by a first rate business, I strongly recommend you select Window Perfections!Steve K
