Family & Veteran-Owned. Next Level Craftsmanship. Unmatched Experience.
“After meeting with 6-7 different companies to get quotes I was very impressed with DZ Renovations. I can’t say enough about this veteran owned company, from the consultation, quote, financing and the job itself. I highly recommend DZ Renovations and will be using them again to replace my windows.”

“DZ Renovations was absolutely great.
They were very friendly, professional, easy to work with, and most importantly they did amazing work. We needed to have our front door and storm door replaced, and Nick Schardt was awesome throughout the process. We chose DZ over several others, and I’m very glad we did.”

“Very good experience from start to finish. Our sales person Anthony was very thorough and provided a great price for roof replacement that met our budget. On the day of install, the crew worked very efficiently. We had to contact the owner regarding a concern we had and someone come out the very next day to relieve our concern. We are very satisfied with our new roof.”

“DZ Renovation did an excellent job replacing my roof. They worked within my budget and were able to move up the installation date when I told them I was on a tight time-line. They may not be able to do that for everybody but I was pleased that they even tried to accommodate. They showed up on schedule and left my lawn free from debris. Would definitely use them for my next project.”

“We found DZ Renovations at the Frederick Home Show. Joe came to the house and provided us with samples and we found what we had been looking for that would provide us with a stable product that would provide is with additional insulation and a lifetime of ware. [...] We highly recommend DZ Renovations for your next project as I know we will be returning.”

“DZ Renovation did an awesome job on the roof replacement for our home! Our roof sustained some hail damage and they provided a reasonable estimate. After doing some research and comparisons, we decided to go with DZ Renovation over the other two companies that provided higher estimates. The DZ team arrived as scheduled and was very professional. My husband and I are very pleased with the work performed and the results.”

“Our entire experience with DZ Renovations was stellar. We had a very bad experience with a prior contractor so we are very wary/picky but Nick impressed us right away with his professional and easy going demeanor. He takes the "sales" out of salesman- felt more like a conversation with a friend and he was beyond wonderful to work with, returning calls and msg right away, keeping us informed and answering TONS of questions, which I def had, and accommodated last minute changes.”
