Replacement Window Testimonials

I love the new windows! They look great and I am very pleased with the whole experience from ordering thru installation. It could not have been any easier.

Nannette S.
Elizabethtown, PA

The first thing they did was to replace my two front windows. I was so impressed with the quality of work that was provided. The workmen were so professional—their work was so clean and looked so good I had them replace my front entry door as well. Again I was so pleased with the work done the door looks great. Keep up the good work and great customer service Zen Windows. I am a highly satisfied customer and I won’t hesitate to recommend you to family and friends.

Belinda C.

We are very pleased with the windows; they look great and we are looking forward to being able to open them up when spring finally gets here. Already I can notice a reduction in drafts in some of the rooms. The crew was helpful and friendly as well. Thanks again for everything.

The window quality and installation are one of the best I've seen. I issue building permits and inspect work throughout the Hershey area and have seen my share of windows over the years.

Glenn S.
Hershey, PA

The work crew arrived on time early in the day and installed the window and steel doors by the end of the day. Since one storm door hadn't arrived yet, they had to return a few days later to install the storm doors and finish some details on the steel doors. I added the interior door job to the list. They finished everything up on the 2nd day (between winter storms). The crew was very professional and courteous and extremely competent. They paid close attention to detail and did a splendid job on everything. I was very impressed with their skills and workmanship.

I would recommend Zen Windows to family or friends. Pricing was fair, workmanship was great! A non-taxing experience.

Matt H
Harrisburg, PA

My experience with Zen Windows of Central PA was excellent from first contact to job completion. Pricing and estimates were quick and well done. The measurer was on time and very professional. All further contacts during the ordering and making the custom windows were professional and quickly responded to. We had three weather related delays, but Zen Windows contacted us ahead of time and rescheduled as soon as possible. Their installations guys were excellent, friendly without being intrusive, even playing with our kids. Of course the important thing is the windows and they are great. Excellent quality and the installation was great. We replaced all the windows on the second floor of our house and it is a noticeable difference. It is now even warmer on the second floor than our first floor. I'm looking forward to summer to see what affect the windows have on cooling as well. Overall I would highly recommend Andrew and the Zen Windows team to anyone. Great job!

Talking to Andrew made me and my wife very comfortable and felt good that he really was concerned about us and getting a great job done. Thank you! Looking forward to our next window replacement!

Great advice regarding Zen Windows. Emailed them Friday night, got info on Saturday, quote on Sunday, placed order today, measuring on Wednesday.

Their price is 1/3 the cost of Andersen AND they have a lifetime unconditional replacement warranty AND the glass has a heat transfer coefficient of .16 compared to Anderson at .30. That's incredible! (lower is better) Many thanks!

Brian Paules

I just submitted the following report on Zen Windows to Angie's List: "After interviewing many companies we decided to go with Zen Windows to replace 14 windows in our home. The price was the best of those interviewed. One company actually wanted to sell us the exact window from the same manufacturer for over three times the price of Zen. The windows were among the best reviewed. The timeliness of the install was great. They had the windows in within two weeks of the original order. The installers were friendly, professional, and provided quality work. They also did a nice job of cleaning up after the job was finished. We often recommend them to friends. " Graded you an "A" in all catagories.


Bob Gray

Dear Zen Windows,

I wanted to thank you for all your help. My new windows are exactly what I wanted and the whole process was exactly what you promised on your web site. I liked the fact that you had an example of the window to show me, but you didn't go in to a "sales pitch". The technician came out to measure and ordered the windows. I do believe the windows came in earlier than promised so no waiting. The technicians were on the job in a timely fashion. They worked quietly and proficiently. They did a great job cleaning up (very important to me). I have been replacing old wood windows a few at a time over the last 5 years. I would like to say that the Thermal Industries windows are maintaining their quality. I enjoyed working with you and your team and I will certainly call you when it's time to do some more windows. Again, thanks.
