Built on Family, Driven by Craftsmanship
👋 Hi, we’re Mark and Katie — the husband-and-wife team behind DZ Renovation. What began with Mark’s first large-scale build in 2016 grew into a passion for helping Maryland families improve and protect their homes. After years of hands-on experience in exterior remodeling, we built DZ Renovation around a simple goal: combining craftsmanship, integrity, and family values to deliver exceptional results for every homeowner we serve.
We’re proud to be a family and veteran-owned business serving homeowners across Maryland. Since our early days, we’ve helped more than a thousand families upgrade their homes with siding, roofing, windows, doors, and gutters designed to look great and last for years.
Our Promise: Quality Work, Honest Service
Our mission is simple — to deliver craftsmanship you can trust, communication you can rely on, and a remodeling experience that feels easy from start to finish. We believe every homeowner deserves respect, clarity, and a job done right the first time.
That’s why we focus on honesty over hype, detailed proposals over surprises, and a process that puts you first. From your first call to your final walkthrough, you’ll always know what to expect, who’s on your job, and when the work will be done. Our team shows up on time, communicates clearly, and treats your home with care — because that’s what we’d want from anyone working on ours.
Experience You Can Count On
With years of hands-on experience across Maryland homes, our team knows what it takes to create lasting results. We combine precision installation with high-quality materials and proven techniques designed for Maryland’s unique weather. Whether it’s updating your siding or installing a new roof, you can expect expert guidance, clean job sites, and a finished product built to stand the test of time.
We live and work right here in Maryland, and we’re proud to help our neighbors improve the homes they love. Most of our work takes place in Frederick, Carroll, and Howard Counties, but we’re always ready to help families across Central Maryland with projects that deserve attention to detail and pride in workmanship.
The DZ Renovation Promise
Our coverage goes beyond standard manufacturer warranties — it’s a true partnership promise. Every product we install is backed by its manufacturer, and every project we complete is protected by our own written workmanship guarantee. Together, that means your home is covered on every level — from the materials we use to the hands that install them.
If something isn’t right, you don’t have to wonder who to call or fight through fine print. You call us — and we make it right. That’s the DZ difference, and it’s why Maryland homeowners trust us long after their project is complete.
Let’s Build Something Beautiful Together
When you choose DZ Renovation, you’re not hiring a crew — you’re partnering with a family that values honesty, craftsmanship, and respect. We’d love to help with your next exterior project and show you what it means to have a contractor who truly cares about your home.
“Engaged DZ Renovations for new windows and roof. My experience was positive, seamless, timely and worry free. From the initial contact with the consultant to preliminary measurements to the install. Professional, knowledgeable and the upmost respect for my home. Laying tarps inside and out to protect my home. Mark and Nick were easy to work with, their word matched their actions. I will not hesitate to call DZ in the future for more work at my home. Thank you”

“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. 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.”
