I want to thank you again for the beautiful windows and for making this experience so easy. I hate to repeat what your other clients stated in the testimonials reflected on your website, but I agree with every single one of them and highly recommend your company for any skeptics out there trying to make decisions on windows. As you know, I worked with you online and through email in getting new windows on my home after my mother recently passed. We are renovating the entire house, and replacing 14 windows was on the top of my list. You and your entire staff/ installers provided outstanding customer service with top of the line quality product and installation. As we discussed, I am somewhat of a perfectionist with extremely high expectations (so my staff tells me) so I was a bit concerned going with a company I found online that no one in my family had heard of or used before on their homes. You met every expectation and it was a pleasure to doing business with you. You and your entire staff responded immediately to any questions or emails and you personally followed up when I fell off the radar and was still trying to decide on which company to use. I was aware of the other window companies in town and decided to get 3 bids to make a comparison. I found Zen Windows by searching through Google and was very impressed by your video and what other people said about the company in the testimonials. I read every single line on your website and reviewed the photos. I thoroughly researched the company in the BBB and other sites and made my decision to go with Zen. I am very pleased with everything and am referring other family and friends to Zen Windows. If you are reading this and hesitating in any way because you had not heard of Zen Windows, please know that I went through the same thing in the beginning, and I give this company my two thumbs up on everything. People are driving by the home and stopping to look at the windows. The home is so much quieter inside now, it unbelievable. I could not be happier. I want others to know what a wonderful company this is and how easy it was to get beautiful new windows at a reasonable price with Zen. I am very happy to recommend this company.

“My window installation experience with Zen Windows was superb not only from start to finish, but also for years to follow. Selecting my replacement windows and storm doors, and scheduling installation, were exactly as promised: uncomplicated, easy, and very reassuring. My window installation was done while I was away, and I returned to a home that showed no sign whatsoever of the major work that had been done, EXCEPT for the gorgeous new products that filled my window spaces. Since this window installation, my house has set the standard for my neighborhood. The elegant simplicity and incredibly lovely color match achieved for me, under Zen’s guidance, have transformed the look of my house. And when I tell people how incredibly affordable the project was, they are incredulous!”

Lucille Caplan

I just wanted to give you some feed back about my “replacement window” experience. Many years ago, I read a book: Zen and the Art of Motorcycle Maintenance: An Inquiry into Value by Robert Pirsig. It explored the metaphysics of quality. I hope that the name of your company is related.

I had a long list of replacement window companies which I narrowed to six companies. One didn’t show up or ever call back after I left a message to reschedule. One did give me a written quote based on my measurements, after he cancelled our appointment—unheard of at any other window companies. Another used sales techniques insulting to any thinking person and followed up with a letter offering an additional 5% off their last window quote. Two would have been good replacement windows; they had good salesmen and fair price quotes, but couldn’t offer your Zen quick window installation.

But of course, you know your business, and knew what my shopping experience would be like—then offered one that replaced the negatives with positives.

I enjoyed meeting you and appreciate the way you do business, but I was afraid it was too good to be true… [With Zen Windows] I chose the right company.

Thank You,

Victoria Wise

The installers did a great job, and were very respectful of our home, cleaning up inside and out as they completed the installation. The windows have made a tremendous difference in the appearance of the home from outside, and the view from inside has been improved with the elimination of the “grates”.

We also noticed a big difference in the noise level, as we do not hear traffic, and were unaware of a recent overnight rainstorm, which in the past would waken me.

Also, the installers had to totally reconstruct the transom window frame in our master bathroom due to rotting wood; they did a tremendous job in this, which took some good carpentry on their part.

Finally, I recently washed all the windows, inside and out, and was pleased with the ease of doing this; I was done with the job in a very short time.

If you want a grade on the overall job, I’ll give it a 10 on the “expectation to results” scale.

Don DePlama

As always the experience with Zen was wonderful. Everyone from Zen showed up on-time and performed the work for the exact amount of the initial quote. But, even more importantly Zen was very flexible when working with me as I was having trouble with my insurance company.

Colin Brown

My experience with Zen Windows has been one of the most positive experiences I’ve ever had with any home repair company. I first decided to give Zen a chance, after sitting through a horrible, high pressure 4 hour sales presentation with another local window company. I have to admit that I went into it expecting the same from Zen, but you quickly convinced me that Zen is a different type of company with a different business ethic all together.

Throughout the process, you were available to quickly answer any and every question I had. Your employees were so friendly and professional. It was the first time I have ever experienced such a high level of work ethic across the board, from owner to hourly employee.

During the installation, the worksite was kept neat and clean, I never once saw trash or debris once the workers were finished. And, the few little details that I wasn’t completely satisfied with were addressed immediately and taken care of within a day.

Zen Windows, the entire crew, has won my respect, referrals, and business for years to come!

Kitrina Spencer

We were so happy with the Thermal Industries windows that were installed during a kitchen remodel, we sought out a dealer for the rest of the house. We were extremely happy to find you — with your no-nonsense quote, excellent communication from the whole team, and a conscientious and courteous installation crew. The installers worked relentlessly and didn’t leave until we were happy. One small follow-up item was handled the same day.
We’ll recommend you to anyone!

Michael & Lori Welsh

I did a detailed search compairing what other replacement window companies had to offer and hands down Zen Windows offered the best product for the best price. The quote was quick and painless. The installation was professional and courteous. I couldn’t be happier with my new windows. My thanks to the whole Zen team.

Nathan Lahr

Thank you again for everything. You have provided the best service ever, and have without a doubt set the bar for excellent customer service!

The Jeter Family

Just wanted to let you know the windows are great. They look and function incredibly. My experience with Zen windows was amazing. From the initial telephone correspondance to the estimate with you, to the install. Everything went exactly as I was promised it would. What an outstanding way to run a company. More should follow Zen windows lead and get back to customer service as a priority. Because of your excellent product and your personal level of customer care, Zen doesn’t have any competition in my opinion. Thank you again for a job well done, and mostly thank you for putting your customer first.

Steve Riley

“Wonderful experience all the way from sales to install- I would always recommend your company and people”

Ernie Reed

“Installers were very professional and polite, would recommend them to anyone. Will refer to anyone I know who needs windows.”

Ann Drake

“We are very happy with the service we received from Zen Windows. The crew did a fantastic job, neat, good craftsmanship-meticulous work! Thank you!”

Kellye Pinkleton

“It was a pleasure doing business with your company. I plan on replacing more of the windows and I will be calling your company. All your employees were very nice and did a great job! We are VERY pleased!”

Jim and Penny Evans

“We discovered Zen Windows…and had a quick response to our email for more information. I thought the estimate was high so we continued our research and had another local company come to the house. That estimate was 50% higher. We had our 18 windows installed within three weeks of my original contact with Zen. We couldn’t be happier. The windows were installed in one day, and the outside trim installed the next day. Our house is quieter and the windows are easy to open, close and tilt for cleaning; having an old two story home, I never thought I’d be able to regularly clean the upstairs windows so easily! Our experience with Zen was an A+.”

Donna Bowers

“Great job, great service. All around well done”

Maxwell Teitel-Paul

I want to express you how pleased Lori and I are with our new windows from Zen Windows. We feel they give our house a much nicer look on the outside, and they look equally nice on the inside. The installers did a great job and from the appearance on the outside, we’ve gotten a number of compliments. I would definitely recommend Zen Windows to anyone needing replacement windows or as in our case, picture windows.

It was a pleasure doing business with you and we’ll send along your name when asked about our new windows.

Paul Farkas

My wife was very impressed with you and couldn’t help but sing your praises after meeting you. She shared with me everything you’ve outlined. We have reached out to a few companies prior to contacting you; but, to be honest we were not impressed with them. Therefore, I did a google search on the local folks doing this type of work and I must say I was impressed with the honesty you displayed on your website. Many appeared to be doing windows as a sideline, when they were not doing roofing, or siding work. I do look forward to seeing the finished product. Especially, from someone who has such a passion for what they do.


Thank you so much for a wonderful job on my windows. It was a pleasure to work with you and your company. I felt very positive about the whole experience–I will recomend you to anyone and everyone who is looking for windows, and wants to feel secure in what they are getting. I will be contacting your company for future projects. Also loved your candle and thank you note.

Sandy T

It is such a pleasure dealing with your window company! Your company makes these things so much easier and no STRESS.


I never thought I would describe a window as “Beautiful” but that was my first reaction when I pulled into the drive…and among the obvious benefits….they really improve the look of the house..I am definetly telling all my friends of our expreience….!! We’ll leave the sign out front as long as it lasts!!!! God Bless!


We have replaced a total of 16 windows in three stages (mostly white vinyl double hung, but three oak windows were just installed in the living room).

We chose Zen windows because the price was by far the lowest estimate and the product was high quality (not the $169 windows that require you to add on a bunch to make it a good window). We have now had our windows for a year and have found them to be excellent in terms of aesthetics, sound proofing, and weather resistance.

The crew was timely and professional, and we have been very satisfied with the service. Plus, Zen doesn’t try to con you into buying a bunch of windows you can’t afford at once – they have been very receptive to replacing a few at a time and have treated no differently than they would have if we had replaced everything at once. That is why we have called them for work on five separate occasions (and will continue to do so in the future).

Andrea, Attorney at Law

I am writing to say how satisfied I am with my new Zen Windows. I recently moved into an older home and could not find windows or anyone to install them. I am so thankful I found you on the internet. The quality of the windows and professionalism of your installers exceeded my expectations.

Marlene Fosnight

“It is embarrassing to admit this, but we received our Zen windows over a year ago and are just now getting around to the feedback. The fact that so many positives surrounding our window purchase remain ever prominent in our minds after 13 months speaks volumes for itself. We’ve had many moons to critique every aspect of the windows by now and cannot of anything negative. What we can honestly say after this long is how very grateful we are for the experience.

The installers were professional, friendly, hard-working and neat, to say the least. The windows are beautiful and functional. That’s what we were looking for. We have both seen more than a few co-workers spend twice as much on windows and still have gripes or this or that bad thing happen in the process. It just wasn’t there for us.

We have been rewarded every day for 13 months a quiet home with beautiful windows inside and out that have yet to produce a drop of condensation to date regardless of the weather. It doesn’t get any better than that. Here is our thank you to Zen Windows for that gift.”

Dean & Sheila

” . . . It is very windy out today…the Cory’s arbor blew over and it is mangled! Plus, it is freezing cold and tiny ice balls are flying through the air and they sting. Burrrrr. Sooo glad we got the windows! We are snug and warm in our cozy Victorian house and I love it.”


Great work, thanks again to you and your installation crew. We are thrilled with windows and the finished look, but just as importantly, your service level was excellent.
Best Regards,


Thank you for the quick turnaround, it is appreciated. You stand above all other contractor types we have worked with!
I appreciate all you have done.

M. Erik Mueller, President

To Whom It May Concern:
I have been looking for vinyl replacement windows for over two years. There are many companies out there ready and willing to sell you their windows. My research found that there are cheap windows for a cheap price and there are nice windows with a big name for an exorbitant price. I was frustrated and bitter at all the broken promises and high-pressure sales.

A friend told me about Zen windows. My windows were ready in two weeks and were installed by the most professional and courteous installers. I am so thrilled with my new windows from Zen, I still find myself standing and staring, not out the window, but at the window. The windows look so good; it’s hard to want to cover them up with curtains or blinds.

Tracy Dearing

Our experience with Zen Windows was wonderful. From the quick, to-the-point presentation and quote to the equally as quick installation. You were very helpful and informative and your installers were professional and cleaned up after themselves leaving behind only our beautiful new windows. The difference our new windows made was shocking. I had forgotten how nice it was to be able to leave our blinds open since our old windows were such an eyesore and made the house so cold. We are very happy with our new windows and would recommend Zen to anyone!
Thank you,

Angel and Jesse Wells

Wanted to let you know how pleased we are with the windows. They look great and will be perfect when stained and the crew was just fantastic both in terms of the speed of the job and the attitude. Truly a pleasure to have around our house.

We can already tell the difference in our house and actually have already lowered the thermostat (Let the savings begin!).

Thanks for the help and patience and support you provided as we went through this. Windows are a big investment and I appreciate your approach and understanding.
Take Care,

Jim Hendrickson

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

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. Dan, 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.

Jill Barker

Hi. I love, love the new windows. The guys were really nice and worked hard. You have respectful, nice employees. I hope your company knows how lucky they are. Thank you.

Cheryl Dawes

Giving your company the complements it deserves is a very easy thing to do. Your installers were efficient, clean, and courteous. They did a stupendous job installing a great window. Everything we were told to expect happened including that we would be more than satisfied w/ the job done and the quality of the windows. The sales pitch was straight to the point and completely painless unlike so many others who feel they have to stay in your home for hours to make a sale. You make it very easy for a busy consumer to make the right decision. Thanks again for such great work and good luck continuing your much deserved success.

Tonya Reed

I want to thank you and your team for the wonderful job they did on my new windows. I was excited to finally get new replacement windows and you did not disappoint me. They are truly wonderful. It is so nice to be able to open a window without all the fuss and difficulty I had with the old ones.
I have had several comments from my neighbors about how nice they look and they even asked for your number so they can have their windows replaced.
Thanks again for a beautiful job.

Brian Hicks

I appreciate the good work Zen did on my windows. I liked the quick and easy sales approach as well as the very quick turnaround time. The windows look great and I no longer feel like I live in a wind tunnel!

Ryan McKinnley

Beautiful! Thanks to you and your company! We love the windows and are enjoying the fresh air now that the weather has warmed up! I can’t believe how quickly and smoothly the whole project went (after the decision was finally made after 3 1/2 months of research and data collection).
Muchas gracias!

You deserve a big pat on the back! You have really gone out of your way to answer the most detailed of my questions to my satisfaction. Believe me, that is a great achievement!! Based on the quality of your product, the available options of Dreamwood and leaded muntins in a diamond pattern, plus your outstanding salesmanship and service, we have decided to contract with your company.

Bonita Fung

The windows are great!
You have all my compliments on the work you’ve done-from introduction to installation. I’ve been very impressed with your knowledge and the way you presented the windows, with absolutely no pressure, but something more like a sense of ease and confidence. [The installers] take a lot of pride in their work and were completely quick, efficient, and capable, as well as friendly, personable and communicative.

Our thanks-we are amazed that something we’ve wanted to have done for the past seven years took only two or so days to complete!
Yours sincerely,

Karin Davidson

“After three no shows and two brutal estimates, you gave us what we were looking for: a great window and a great price. And thanks for not taking up our entire evening”

Bob and Sue

I do rehabs and will use you for everyone from here on out. Nice job.


We wasted two weeks shopping before we found Zen Windows. Dan, you were informative with no pressure. [The installers] were on time and finished 19 windows in one day. Hat’s off to you guys!


I liked dealing with Zen Windows so much that I asked them for a job


This one was a first. I placed an order and went to get my checkbook. Dan told me “not a penny until the job is done and you are completely satisfied” Well we are.

Phil and Lynette

Our heating bills went from $400 a month to under $150. Thanks.


What a window. What a company. I’m telling all my friends to use Zen Windows
