Greg and team at Windella are awesome! Greg is extremely helpful in explaining options and talking through the process, transparent on pricing, and delivered and installed windows and doors right on time. Would recommend Greg and his team to anyone looking for new windows and doors.

Matt P.

We had an all around great experience with Windella. Greg helped us find the right window option for our whole house replacement and was super helpful throughout the process. The installation team was excellent and our old house was treated with expert care and craftsmanship. Everything was smooth sailing from start to finish. We couldn’t be happier!

Sara K.

I couldn’t be happier with the work. I had all the windows in my house replaced by Greg and his guys. The entire process was low stress and the price was great. The installers did some of the cleanest work I have ever seen. Greg was a professional from beginning to end. I’d highly recommend him for any window and door work.

Joseph O.

Huge thank you to Greg and his team! They replaced 22 windows and the front door. I cannot recommend them enough! We placed our order in mid January, and I am so pleased that on March 9th, the job is complete. Greg was wonderful and easy to work with. The installation team was top notch. They worked quickly but diligently and neatly.

Mary-Ellen G.

I highly recommend Greg and Windella. They completed a job for a very large picture window ahead of schedule, on budget, were easy to work with, kept everything clean, and I love the result! After my fantastic initial experience I went on to have Greg and Windella add two additional large modern windows. Again, the job was done earlier than expected and on budget. They delivered high quality results.

Jonathan H.

Greg and his team replaced our old back kitchen doors with a new Pella slider that looks fantastic. He was easy to work with and knowledgeable when walking through our options. His installation team was very professional, diligent and added additional touches on the interior to match our surrounding features. I would absolutely recommend his services.

Ryan M.

Thank you Greg for quick, courteous, excellent service. Greg came to fix an older sliding door which Pella was no longer willing to service. Door is now like brand new. Thank you for your willingness to show up for a small job. We'll be sure to remember you when it's time to replace and we are happy to recommend you.
