First, it was the best lead time out of all the window suppliers in Calgary that made the decision easy for me to purchase my window through Gienow. But their customer service experience as well from dealing with sales through the installation the experience was very smooth. Not only that, their lead time, which was already better than other suppliers, was even shorten when they called me to inform me they got the window in sooner than expected.

I am very pleased with the new windows . Alex the installer did an excellent job, courteous and friendly. He worked hard and left everything clean. Andrew the sales rep was very honest and explained things very well, also Bryne the man who came to take final measurements was friendly and professional.
I will definitely hire this company for future projects.

Alex and Vlad came to replace the front door and patio doors. They did and excellent job! We are very happy with the quality of the quality of the doors and professionalism of the installation.

Gienow came and did a free quote then had Tony and Alex do the install. They worked long hours and did a great job on a few tough-to-acces basement windows. Alex explained everything to me after the install. Overall quite happy with the work and at a competitive price.

Second window replaced with this company. The crew was awesome. I know the quality is there. There is condensation on the outside of the window..none of my other windows have this. After searching on the internet, it was confirmed that this shows the quality of the window, ie temp differentiation staying outside. The room now feels warm and we love how clean of a look the windows are. Great quality, great crew for install, and a reasonable price. Happy customer.

The Installers were amazing. They were courteous and very professional. They made very little mess & there was minimal disruption. The end result is fantastic and I could not be happier

Five years ago we replaced our living room windows and a bedroom with Gienow Renovations. Since they did a good job then, In September 2019 we decided to do the rest of the house; two bedrooms and the kitchen. The whole process from our salesman (Jay) to the install crew (Alex and Tony) went very smoothly and professionally. Install looks great. Fit is good. Old windows and garbage cleaned up and removed from site. Would recommend and use again when we have to do the doors.

We hired Gienow about 4 years ago to replace our top floor windows. Like most of us, we could only afford one floor at a time. Our main floor had original single pane, wooded frames and they creaked all the time. The North wind made our main floor chilly and finally decided to change them out.

We got a couple of quotes but new that Gienow would be the best for us. It took about 3 1/2 weeks until windows arrived and our 2 day scheduled install for 11 windows. The installer Bryce and his team were amazing guys and very professional. The place carpet runners down over ours and cleaned up all the time. I can't say enough how awesome they were.

Highly recommended! We had all our above grade windows replaced (3 large, 1 medium, 3 bedroom - 7 total) in May 2019. One of our major issues was a large 2nd floor bonus room window facing west which would heat up our house every summer. We opted for the triple pane windows and have noticed a dramatic difference this summer. We are so glad we had our windows replaced and absolutely love our Gienow windows. Installation took 2 days and we had no issues whatsoever. I waited until after summer because I wanted to honestly say our windows exceeded our expectations. They have and are worth every penny we spent. We'll be calling Gienow for our doors next Spring.

It was a great experience, the gentlemen who installed the door are very friendly, polite, tidy & efficient. Everything worked like clockwork!"
They came on time, cleaned up afterwards, it was a positive experience.
