Customer Testimonials

Your installers are great polite Clean knowledgeable about the product. I’m very satisfied. I LOVE MY WINDOWS!!!😆
Install crew was quick, considerate, a d the product is amazing! I plan to do the rest of my home with these windows!! Highly recommend!!
These guys are amazing. Very nice respectful and clean.
Chris and Rachel were a pleasure to work with. Will definitely refer to family and friends!
A group of wonderful people offering a great product. From the sales pitch to the end of job checklist, the Window Doctor has been great to worm with. The sales team was very knowledgeable about the product. It didn't feel like they were using any underhanded sales tactics. Its rare that you find a sales person who seems passionate about the service they provide, and not just about the commission they recieve, and I had the privilege of meeting with two of them. Admittedly, walking into the meeting, I was originally just planning on getting a quote, to lazily bouce between installers to eventually replace my 30 year old windows... maybe. But, after speaking with them, I felt like I was getting a great deal (as compared to other competitors that had provided partial quotes in the past) on a top of the line product.
Now on to the measuring and ordering crew. Just generally good people. Great to chat with, very knowledgable about follow up questions that I had about product specifics.
I was so impressed at this point that I called in and asked for marketing material to help provide some good referrals.
But it gets better. Install day came around and the product is immaculate. It has a very finished look with custom trim to match my specific project, cut on site to insure fitment. Some other companies will use ultra wide trims to hide mistakes. A bead of caulk is all these guys need. They responded well to requests I made, looking for solutions instead of getting defensive. It was great to work with them!
Excellent windows and installation. They installed 7 windows and one sliding door. All of them look and perform better than expected. Installation was quick and efficient. The installers took care of all my concerns immediately and cleaned up any debris.
Professional, customer friendly, and local owners. All things we need in this country again.
Great experience! They were quick with install and so nice to my dog made her feel comfortable the door is absolutely beautiful
We replaced some of the windows in our home and are extremely happy with Window Doctor. We built our home and I understand windows and this was quality work and a good operating window. I will use them again
Used them again 2 years later to replace a door. Wow, what a great built door and the installation was seamless. I would highly recommend
Awesome job. Installers were great and finished job looks terrific.
Very friendly staff and always helpful. Parker if great making sure all goes well
They did a great job! Cleaned up and fixed what we asked.
Roof Doc crew actually came earlier than promised and completed the roof in two, rather wintery days. From start to finish they kept us posted as to what they were doing and why. At one point they discovered that there were two roofs on the home when they had figured one and never charged us any difference. I recommend their work.
These guy did an awesome job very clean an the product I'm very pleased with thank you
The installers were on time and were very neat about everything they did. They answered all of the questions we had as they worked. I like how the windows look on the inside and outside. Done in one day!! wow!
The new windows are great! I can already feel a difference. The sales rep was fantastic and the installation went smooth. I couldn’t be happier.
Great, quality, product that was installed quickly and efficiently by well trained and mannered technicians!
We had 5 windows replaced including a Bay window. From start to finish, the process has been seamless. All windows were installed within 4 hours or so. They had to come back in the evening, the same day, to do some trim and the guy was back when he said he would be and the job was completed. Love our new windows so far.
Had a great experience with getting a quote with presentation of products, finance options, ordering, quick turnaround time, and great installer! Windows look great and sealed well. Thank you for an all around wonderful and easy time.
Great teamwork. Timely procedures of putting windows up and follow thru of screens to sealing windows measuring and clean up. Blessed be the team today and future windows installations.
The crew did an amazing job. Not only were they kind but considerate towards me and my family and working through the cold and snow in a very timely manner!
Love that they are family owned, operated and have Christian values. Very happy with my windows and my installer Jeremiah was very professional and did the entire job by himself in 2 days, and in the cold until everything was done. I received high-quality windows with installation for what I considered to be a very reasonable cost. Totally recommend The Window Doctor ❤️
Very professional, cleaned everything up nice, in and out in no time! The window looks great, I can’t wait to have a functioning window this spring! 100% recommend!
Had eight windows installed By The window doctor. very professional and friendly technicians that did an outstanding job. very satisfied . I highly recommend this company to family and friends.
The sales person was nice very helpful and gave me what I wanted. I liked that he didn't try to sale me something I didn't want. The guys that installed the window was very nice and polite. I'm very happy with the job they did in installing the window.
Well it has been almost two weeks since we have received our new windows from The Window Doctor and boy let me tell you they are amazing! Immediately that evening we could tell the difference of not having any air coming through our windows anymore but I wanted to give it a little time before I wrote my review. Right from the beginning the gal that came and measured and told us about the company to the insulation has been wonderful experience for us. The windows are such nice windows there is no noise from the outside ( if the dog didn’t bark we would never know anyone drove by) they look very nice from inside and out and really spiffed up our house on the outside and the quality is fantastic. There is no cold air coming in any longer. What a great investment we made with The Window Doctor on our new home!
Very easy to work with! The installation was very organized and efficient! They were very informative during the installation! We would recommend this company!
They were very efficient and did an awesome job gave my home a refreshed look
Fantastic experience and efficient process. Can’t beat the warranty and their financing was attractive as well.
We had 13 windows installed by 2 installers. The first (cold and snowy) day, all windows were put in over about 5 hours - no lunch breaks! Only one window had minor inside wood trim nicks, which they promptly repaired. That is wonderful considering how they had to work to get the old windows out. They came back the second day when there was no snow and worked for over 5 hours "wrapping" the outside of the windows with a brown trim that matched the rest of our trim. Hunter knew how to do this from the inside of the house on the upstairs windows, so no ladder scratches or dents on the house. It was beautiful! I love these windows! They slide easily and tilt in for cleaning. Also a stop on them for security with a window open a little for fresh air.
Hunter and Corey were great. Very friendly and answered all our questions. Very professional and they know their job. The new windows were in In no time. Very pleased with The Window Doctor. Family owned and highly recommend
The followup sales rep was great to work with and the installers did a great job in putting the window in. It is definitely making a difference and has reduced our heat loss. Nice looking window!
Installers were professional and friendly and answered our questions as they came up. Future window replacements however will only be scheduled during warm months.
Their friendly service, amazing warranties and their kind installation crew. I myself had wonderful Custer service and quick installation. I highly recommend you look into their services and warranties which were a selling point for me having two growing boys. It’s an American made product with wonderful values I stand behind. I look forward to doing more business with this company.
My windows were just installed. I am very pleased with the outcome. Everyone that helped my project from sales, customer service, to measuring to installation and the window wrap did a thorough and awesome job. Brad and the crew were great! They explained everything I need to know. I am looking forward to enjoying my windows for many years to come.
They did a great job on replacing old windows and a sliding door on my house! Definitely recommend! Quality work
We had 6 windows replaced in our home. The installers were friendly and fast while completing quality work. They ran us through everything we needed to know about our windows. Will be doing business again for the rest of the home.
Did an excellent job, and got done in a timely manner! Very impressed and would recommend !
We had all 13 of our windows replaced in the house and they were able to get them all done in one day. The team was very efficient & professional. We've noticed a difference in how warm the house is since they've been installed.
Jeremiah did a fantastic job! His customer service was great as well! My seven year old loved talking his ear off. He also cleaned up after he was done, probably better than before he started the job! 👍
Thank you!!
Windows came in real quick, crew was knowledgeable and respectful of our home and pets. Cleaned up as they went along, and would recommend them for any window job. Plus their warranty is amazing.
