I just had 20 windows installed by The Window Doctor over the last 2 days. As soon as the installers arrived they set up their equipment and got right to work. They were polite and very courteous to me to and my husband. They answered any questions we had and showed us how the windows operated. I appreciated the knowledge they had about their product and the care they took in my house during the installation. The new windows look great and operate so easy. I can't wait to see the difference they make in our utility bills!

Called to get an estimate for front door replacement. Initial estimate wasn’t affordable for me, but after about 20 minutes of phone calls, we got the price down to something that was definitely affordable. The installation was completed today, and the door looks beautiful! I’ve already received compliments on it. The installer showed tremendous dedication—his partner was delayed, so he completed the installation alone. As it was nearing completion, we had one of those brief but torrential spring showers. He worked through it a finished the job. I was impressed with his knowledge, courtesy, and work ethic. He made sure to keep me apprised of his progress every step of the way. I’m VERY pleased with the job! I will call The Window Doctor first if I decide to replace any windows in the future. RECOMMENDED!

We are happy with our new windows. Being able to open from the top or bottom with safety locks is nice. The tilt in to clean is going to be an awesome help! Our installation team Brad and Collin were top notch!! They made sure to keep the gate shut and pay attention to our attention starved pup. 😊
Brad kept us in the know all through the installation process. We were very pleased with their work.

After a few different estimates, we chose The Window Doctor for our new windows. I’m so glad we did because they made it much easier than Anderson and were much more affordable. They were so affordable and easy to work with that we were able to upgrade my giant 3-pane living room window into a custom bay window! We got 2 custom size sliding doors, a giant 100+’ bay window, a double hung window, and 2 oversized picture windows with double lifetime warranty for the price of 2 Anderson doors. I love natural light and am so excited I didn’t have to settle on my windows. Instead I got them upgraded! Thank you!!!

I was impressed with The Window Doctor from my very first contact with their representative, Rachel. My opinion grew as I met the sales team, including Mike who went above and beyond at my house - he even went up in my attic assessing for moisture- all the way to the respectful manner the installers (Brad) treated my property and made sure I understood all that they were doing. This team has developed quality products and installment. I was so nervous about making this investment, but after seeing the results I am completely confident I made the right choice! I love my patio door and windows. The Window Doctor team has followed up with me and answered every question, making sure I am completely satisfied with my purchase. I would highly recommend the Window Doctor to anyone in the market.

Great Company to work with... from the start with Rachael at Monroe County fairgrounds to Dale who gave us an in home demonstration of the products to Tammy in the Office and Brad and the crew.... Nothing was ever pushed or rushed from sales to installation... a high quality product and service... could have went "cheaper" but we went down that road before in a previous home of ours.... a little more expensive but, worth it... life time gaurentee... have and would recommend the Window Doctor ... any future needs for additional windows they'll be the ones we call. Thanks Window Doctor for the kind of Company you are!!!

Had new metal roof installed and replaced exterior French doors. Installation of both was done promptly and professionally…. Great communication throughout…. Quality product. A couple of items were needed during install process & they were provided immediately! Both roof & door installers were very conscious in clean up after done…. roof install was done during a major snow storm… not an issue.
Door installers were good …. Especially Cody - good workmanship & follow up!!

Brad and his crew were awesome! Very professional and courteous. Doing one window at a time, the temperature never dropped more than 2 degrees in my home on a very cold and windy day. Very impressive with the company. I would recommend them to anyone and plan to. Thank you again!

Crew of 4; very polite and respectful. Very knowledgeable about their job and informed me of the progress as they moved throughout my house to all the windows and doors. They cleaned the different areas as they worked and disposed of the trash in their truck. Nothing was left on-site. I have 2 friendly dogs and the crew was great with them, careful of open egress doors and petting them as they worked. When the job was finished each of the crew thanked me and offered assistance if I had any issues in the future. All 9 windows and both doors look great! I'm very happy.

We had a follow up visit from a 3 window instal. Customer service is above and beyond. They treat you like family and friend, even bringing a gift basket with goodies. The window doctor definitely gives you the whole experience, start to finish and beyond. Love this company and the people that work here.
