Great experience with Window Factory. They were really friendly and patient going through all the options with us. We were pleasantly surprised with the price and when it turned out they had made a mistake in the addition, they stood by the original lower estimate. 
The ordering, measuring, and installation process went very smoothly. They brought 6-8 guys out to install and everyone was very polite and respectful. They got the work done in half a day when I thought it was going to be a full day. They reinstalled the brackets for my blinds without me having to ask. The windows look great and the installers left the house and yard clean and tidy. Couldn't be happier with my new windows and so glad we hired Window Factory.

It has been almost 6 years since installing my new windows, but it was probably the best home improvement I've ever made.  These windows look great, are energy efficient & have held up very well.  The Window Factory did a great job with the installation, & had everything finished up in one day.  They were friendly, professional & left the job site clean after installation.  This was money well spent, & I was very happy with their work.

The work was done in a day, and the workers were clean and professional.  I have said that the windows have paid for themselves with the money I saved on my heating/air conditioning bill.

They were fine and did everything they said they would. They followed through and delivered when they promised. The quality of the installation was fine too.

AWFUL!  The owner literally screamed at me over the phone.  Eventhough it's been years since this happened, it still stands out as one of the WORSE experiences I've ever had with a company.  I will NEVER use this company again. In fact, the windows are now falling apart and i need to replace them.  The workers were okay but I know I could have a found better, more professional company.

They did a great job. They came on time with 5 guys and were able to complete all the windows in about four hours. They did a great job on the installation, cleaned up thoroughly,  and besides that, they were easy to be around. I would definitely recommend them.

They did a good job. The type of window they had was good for what we needed. They were able to install the window quickly and did a great job at selling it. They cleaned up well.

The windows are wonderful and fit well. It was a good experience. I liked how fast they completed the project. The work was done mainly from outside of the house. When they disrupted some trim they responded right away by priming the woodwork. Their prices were reasonable. I was very happy with the customer service and the result of the installation.

I thought that the salesperson used a hard sell that I didn't appreciate.

Everything turned out fine. The installation was flawless and the windows are high quality. My only complaint was the high prices. Everything was handled professionally and beautifully. I plan on using them again. The crew was fantastic to work with and completed the work in the six units in two and a half days.

I went with them because my father had used them in the past and I liked their work. I received bids from 2 other companies and Window Factory was the best bid. I was impressed with how neat and tidy they were with the installation. I had a specific window of time that I needed the installation done in and they worked to fit me in the time frame I needed.

They did the entire job in one day and were very efficient. They did a good job cleaning up after themselves. The scheduling and service were both timely. Their prices were reasonable. This was the only time we have used them but we would use their services in the future because they did a great job.

They zoomed in, took all the old windows out, installed all the windows and left. They took all the old windows with them. They did the job quickly and did not waste anytime. We have been very pleased with the windows. They were professional and knowledgeable. I would recommend their service.

We were very happy with the work. They did it timely and within the budget. They were professional, polite, and informative. They sat down with us and explained their entire process for when it would be completed. They met all of our expectation.. It was very well done and we are very happy with it.

They were very professional! The windows really cut out the traffic noise as I live on a busy corner. It was a good price and I love my windows! It was an overall wonderful experience. I have recommended them to other people.

In 2001, we chose this company because we liked the description of the retrofit window replacement technique, the quality and look of the windows, and the competitive price. However, our experience with the actual installation has not been so good. All the work was performed by a big crew in one day, but too many of the installation decisions were left to the crew who shortcut appropriate techniques. We have had a number of leak problems, which went undiscovered for the rainy season and resulted in moldy wallboard. The cause in all cases was improper installation, lack of installing the promised flashing, and lack of caulking altogether around one window. When I called, the company did come out to reset two of the windows and caulk around the one, but by then, avoidable damage had been done. Since the installation, I have watched the same windows being installed by another company, and I learned a lot about how the job should have been done in the first place.
