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.

Tonja Bell

Great product! We live in an older home and just had all of the windows replaced. We can’t believe how much warmer the house feels and how beautiful the windows look.

Tommy Horton

Friendly service from the office staff to the installers.

Patty Rupert

The wait for the customized windows was worth the price. We can already feel the difference keeping the cold air out.

I would like to personally and professionally state -
That promises made promises kept. My wife and I are very happy with the roof we understand that things happen but the reaction time and the unbelievable customer service from Lance and my salesman Dale Goodson along with The ambassador team that came to my home to do a final inspection of our roof. I would recommend this company being in sales for almost 40 years this group of people know what they are doing and they stand by their mission statement. Roof doctor of subsidiary of window doctor amazing!!

Chris and Riley were so friendly! We got aquatinted with them at a home show and they took a nice chunk of time to educate us on their company and what makes them unique. Highly recommend to anyone looking for great service from a family owned business!

The Window Doctor put a new roof on our house. Unbeknown to us, the roof was not only getting old but the original roof from when the house was built was still underneath. They were competitively priced with other contractors that we had received quotes from, they were able to start the project sooner than expected, were very efficient at finishing the job and it looks amazing. We have gotten tons of compliments on how it looks.

Scott Graham

The Window Doctor team was professional and proficient from our salesman to the installation team. The installers went the extra mile to make sure we were happy with our windows, even noticing things that we might not have noticed and bringing them to our attention and addressing them immediately.
We are amazed at what a difference new windows make in the appearance of the house.
We are very pleased!!

This review is for The Roof Doctor side of their business. They came to the house to quote our roof in June/July. Gave us a somewhat reasonable quote for the pitch of our roof, so we agreed to have them reroof our home. The crew finally came out at the end August and completed the roof in 2 days. When the wrap-up crew came out, my husband pointed out a couple of areas of drip edge and fascia that was not put back, so they stated they would send someone out to fix it. Three weeks later, our roof is finally buttoned up and beautiful. The wait was a bit painful, but they were true to their word and completed the task prior to October.

The windows in our home have been breaking and wearing out over the past few years. We were introduced to the Window Doctor at the St. Joe County Fair a couple of years ago. Because they have a local office we decided to contact them for a quote. Everyone we have dealt with, from the salesman to the installers, has been very professional and friendly. We love our new window. They look great and they open and close easily. We're very happy with our purchase and would recommend The Window Doctor to anyone.

Wendy Farrell

Professional and polite crew. Very pleased with the quality of windows.

Eric Hostetler

Brad and his crew did a great job installing our windows. There were some unexpected challenges once the old windows were removed, but they solved the issue. They worked efficiently but also took their time to make sure the job was done right.

Julie Howe

I Love my new windows! This is day two with my new windows from the Window Doctor and I feel a noticeable decrease in the temperature of the rooms. The windows really block most of the summer heat! The installers were courteous and very efficient. I love the look of the windows! I would highly recommend using the Window Doctor for your home.

What a great company! From quote to installation!, true professionalism!

Scott Covert

Extremely impressed with Brad and his team from the Window Doctors who installed these windows. They were courteous and very professional. We have an older house so window frames aren't exactly square, but they made it look seamless. Excited to see how these windows perform throughout the seasons.

Dennis Rennhack

Our new windows look great! The installers were professional and courteous. These windows come with an awesome warranty and even an energy saving guarantee. The windows are competively priced and the company is great to work with!

I had some really old windows. I went with the Window Doctor due to cost, product, and service. I have fallen in love with my home again. It looks so bright and open. Hunter and his partner did a great job with installation and clean up!!! I would use them again!!!

Hunter and Jonah did an amazing job installing our windows and storm door. They did not waste any time getting everything installed; even after having a misfortune event happen before arriving. They were super clean and proficient!

Tracey Bumpus

Sales associate was very friendly and knowledgeable. He spent time chatting with us to get to know what we were looking for. The work crew were extremely knowledgeable and did a fantastic job . They were respectful and kind. They cleaned up and made it look like they were never there. The house looks great. My husband and I are both very pleased! I would recommend them to anyone!

Marie Steinke

The installers arrived prompt. He introduced himself and hit right to work. A crew of 3. They didn't even take a lunch break. Got them installed in a timely manner. Good workmanship and cleaned up after themselves. They did step on a few of my flowers, but I think they'll survive. All in all I'mm pleased with my new windows.
