1st Choice did a great job from initial consultation to final window installation. We had to replace two weather worn windows. Tom (owner) did our in home consultation giving us the best price after meeting with multiple companies. Chris (owner) met with us to sign the final contract. Brandon and Dusty completed the install in a timely, efficient, and professional manner. Overall, very pleased with the entire experience. Thanks 1st Choice!read more

Just had my windows replaced by 1st Choice and I am very pleased with the results. The windows look great and I immediately noticed a difference in temperature from my old windows. The cost was about 1/3 of the other estimates I received, plus I had a shining review from my immediate neighbor. The guys replaced 3 massive windows (7' x 7') and a sliding door in about 6 hours -- something I was sure would take two days. I was pleasantly surprised that they were done early! They cleaned everything nicely too. Their office staff was also friendly and personable.read more

1st Choice replaced all the windows in our son's home earlier this year, and it was such a positive experience that we hired them to replace 2 at our house. First of all, everyone we interacted with was personable, knowledgeable, and professional. Their windows are high quality and competitively priced. The installation went smoothly and they cleaned up when they were finished. I hold my breath when I have to select a contractor--we've had our share of bad experiences. That being said, I can whole-heartedly recommend 1st Choice for your new windows!read more

I found 1st Choice Windows and Siding on Google and gave them a call due to all their high reviews. We had Chris out the next day to do a measurement for replacing our back door. We choose the Pro Via door, with glass. They are custom made with color options (inside and out), as well as window options. It takes sometime to get the new door as they are made back east. I am glad I waited as the door is great quality. Kelly did the door install and was professional and did a great job. You can tell the quality from how it opens and closes, feels like a nice solid seal. The window is great, keeps out the summer heat but lets in the light.read more

They were amazing to work with. Install happened in one day and they were done by 1PM. Chris came by for the initial consultation and was beyond helpful. When they came to measure for our windows they were very respectful,especially with our toddler. We will be recommending them for windows and siding to everyone we know.read more

1st Choice Windows and Siding gave us good prices, a good product, and excellent service. We ordered several windows and a sliding glass door and they came in quicker than anticipated. The installation was done very well and we are very happy with the results. Chris Noblitt went above and beyond and installed a dog door for us as well. We would gladly use them again.read more

After adopting a lovable dog a few months ago we determined that a doggy door was necessary. After buying and returning one from Home Depot I contacted 1st Choice and was thrilled! They talked to me about options and I ordered that night! They were quick, professional and made sure everything went perfectly. When we are ready to replace our windows we will contact them! Max thanks you guys as well woof woof!read more

We moved into our house the summer of 2013 and quickly realized the window that was in the front of the house wasn't keeping the room warm so we decided to get it replaced with a triple pane window and we noticed an instant increase in the room temperature. The install was done quick and seamless, there was no issues and they were timely with everything. I felt like I received great customer service from the beginning to the end of the process. I recommend them for any window and siding job!read more

 FROM OUR HAPPY CUSTOMERS

“I had the pleasure of working with 1st Choice for new windows for my new house. I believe the quality of the windows, workmanship, and lead time to get the job completed were very satisfactory. I really enjoyed working with Tom and him taking the time to explain and show me the different types of glass and materials used. Ultimately yes I would recommend them for windows, and probably any other work they specialize in.” – Jody Davis
