Testimonials

Tommy McCauleyTommy McCauley ★★★★★ I'm happy with the craftsmanship of my deck and patio. Now I'm having them install a fence due to their professionalism in honoring the lifetime warranty along with the quality.Sonia NorthSonia North ★★★★★ I had Medallion install my 10 years ago and had absolutely no issues. I have been enjoying it ever since. However, I put a firepit on it without the proper matting and burned several slates. I called Medallion and they came out an fix the properly immediately at a great cost. I am back out enjoying my deck once again. If you need any work done for doors or deck, do yourself a favor and call them like I did.Nathan FaisonNathan Faison ★★★★★ I am very satisfied with Medallion Door's installation of my front and rear doors. From start to finish, working with the sales rep on my order, and Peter's concise measurements, and Nelson & Nelson Jr's professional installation, the whole team did an outstanding job! If you need quality doors, I recommend Medallion Door and Window Company for professional installation. You will truly be satisfied! They deserve a five star rating! Thanks to all!!Janice AlstonJanice Alston ★★★★★ Medallion did an excellent job installing my front porch rail. After submitting the request, the rail was installed within 2 weeks. The process was quick and smooth, and the rail itself is very sturdy and looks great. I’m very pleased with their work and highly recommend them!Jerene ShaheedJerene Shaheed ★★★★☆ Company replaced my front door and my roof. Project managers are responsive and open to change orders. Installation was accomplished expertly.Terri Tutt DanielTerri Tutt Daniel ★★★★★ Medallion did an excellent job on my paved patio and they have done excellent other work for me so I keep hiring them over and over again, deck, front door, front tinted security door, backyard French security door and fence.Michelle Mc-Adams BraxtonMichelle Mc-Adams Braxton ★★★★★ Brett, Andy and Peter did a great job with installing a brand new closet. Good price . One day install, and closet looks great.barbara smithbarbara smith ★★★★★ I had new windows and a patio door installed around October 2024. Unfortunately, my 90-pound German Shepherd ran through the screen door—definitely not his fault. I wasn't fast enough to open the door, and if you know anything about "zoomies," you’ll understand! It looked like the door was open, and he went straight through it. Long story short, he tore up the screen.There was some miscommunication when I tried to schedule a service call. Initially, I was told I needed to remove the door myself. While I understand that sending someone out takes time, I made every effort to fix the door on my own. Once I realized I’d have to remove the entire frame, I was frustrated.That said, Medallion made up for the miscommunication. At one point, I was ready to go elsewhere, but they came out, removed the door for me, and fixed the screen. Peter, the manager, personally called to apologize—which I really appreciated. He’s a stand-up guy, and that gesture showed integrity.I love the new windows and patio door. The lock mechanism on the patio door, which allows it to stay cracked open while still being secure, was definitely worth the investment.I’ve seen some mixed reviews, but if you're willing to communicate and work with them, Medallion does aim for customer satisfaction. I’m glad I stuck with them.Finis WhiteFinis White ★★★★★ Medallion did a great job completed the deck. From the initial meeting to the completed job was worry free. The deck looks great and very sturdy. The only issue was that the spindles were making a slight noise due to the vibration from walking. I called Erwin and it was fixed in two days. I'm definitely going to use them for future projects.Chris EleyChris Eley ★★★★★ ⭐️⭐️⭐️⭐️⭐️We recently had the pleasure of working with Medallion to install a security door and custom closets in our home, and we couldn't be happier with the results!From the very first interaction, their team (Brett, Tyler & Peter) demonstrated exceptional professionalism and expertise.
