“Hi, we’re Mark and Katie — the husband-and-wife team behind DZ Renovation…
Our story in construction began back in 2016, when Mark managed his first large-scale build. What started as a single project quickly grew into a passion for helping families improve and protect their homes. By 2018, we were fully immersed in Maryland’s exterior remodeling industry.
Family is at the heart of everything we do — ours, and the families we serve. As a family and veteran-owned company, we’ve helped more than a thousand Maryland homeowners enhance their homes with siding, windows, doors, roofing, and gutters built to last.

“DZ Renovation replaced my roof and siding. Honestly...
I feel that I could not have chosen a better company for these two projects. Nick (Senior Consultant) was knowledgeable, professional, personable, patient and accessible throughout the entire project. Additionally, Mark (the owner) was accessible and responsive to my concerns and questions in a very timely manner. The quality of the workmanship is first-rate. DZ Renovation is a company that is exceptionally customer-oriented, while offering competitive prices, quality products and superior services.”

“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.

“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.”

“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.”
