Testimonials

Letitia MayRich85Letitia MayRich853 days agoMedallion Security is definitely a company that you want to install your security doors! Ed Y. was my salesman, and he was extremely responsive to my calls and quickly provided a fair estimate for my security door projects. Peter H., was my project manager, and he ensured that my doors were custom made and installed in two weeks! Both Ed and Peter were also very professional, friendly and experienced. I LOVE my new security doors and Medallion Security has a lifetime customer!Richard JohnsonRichard Johnson14 days agoI purchased a custom closet from medallion and it was one of the best experiences I have had in dealing with home improvement. My salesman Brett S. Was very helpful and knowledgeable. He provided me with what I wanted and did not try to upsell me. The installation went off without a hitch and they were super patient with my dog who supervised the entire installation. I am for sure going to have them come back and do all my closets and pantry . Great Job!!!!!!Cluster DaviesCluster Davies22 days agoMy husband and I finally agreed to change our front entry door after living in our home for over 25 years. We consistently sought various door manufacturers and ultimately decided with Medallion to achieve our goal of replacing our door. Needlessly to say that was the best decision of our lives! We met with the Medallion sales representative, Erlin, on several occasions and he meticulously provided us with various options to help make our decision easier. He was patient, knowledgeable, and very much accommodating to our many questions and whims. Their installers were experienced and performed the work in a timely and complete manner. We are very pleased and wholeheartedly appreciate their work!Brent PaigeBrent Paigea month agoA very nicely installed black security door that made our house stand out even more.

They helped us to not only convert a bedroom into a master walk-in closet area, but also to demo a wall and combine 2 smaller closets into 1 larger closet area, that leads into the new master closet! The process was seamless and they made sure to fully communicate during every step. I want to extend a huge THANK YOU to the crew who did our wall demo and painting, plus Tyler, Brett and Peter (and Ms. Linda too!). You helped to bring our vision to life and executed everything with a high level of professionalism, we really enjoyed working with you!Doriflore EdwardsDoriflore Edwards2 months agoMedallion is a great company to work with.

The installation was surprisingly quick. They finished in less than a week. Having the patio there makes it so much easier to take our dog back and let her use the bathroom or play. Before the installation we always took her through the garage and walked around back. We wanted to have the installation completed before our wedding date and it was completed well before then. I have nothing but compliments for how professional Medallion and more specifically Erlin (our Medallion salesman) conducted themselves. Only thing that could've been better was if we had gotten the installation for free (ha).Leslie SmallwoodLeslie Smallwood2 years agoMedallion provided A1 services in replacing my entry door. They were professional and Peter services beyond my expectation. Thank you medallion.Gina MGina M2 years agoMy sales representative Erlin was professional and my security doors were ready before the date that was initially given.
