“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.”

FAQ
What types of exterior doors do you install?
We offer a wide variety of exterior doors to match every home’s architecture and budget — including front doors, patio doors, and screen doors. Whether you prefer the look of smooth steel, elegant fiberglass, or decorative glass accents, DZ Renovation can help you find the right exterior door for both style and performance. Our experts provide expert advice on materials, finishes, and energy-saving options, so you can make a confident choice for your home’s curb appeal and comfort.
What materials are best for durability and energy efficiency?
The best exterior door materials depend on your goals for maintenance, security, and aesthetics. Fiberglass doors are extremely durable and resistant to dents or warping, while steel doors offer unmatched strength and insulation. For homeowners who love natural light and fresh air, adding glass panels or a screen door can help brighten your space and connect your interior with the outdoors. We’ll review more options with you during your consultation so you can select a perfect door that’s beautiful, efficient, and built to last.
Do new exterior doors really improve security and efficiency?
Absolutely. Replacing an old or poorly sealed door can make a major difference in both comfort and protection. Today’s exterior doors feature reinforced frames, advanced locking systems, and weather-tight construction that enhances security and energy efficiency. Our professional installers make sure every new door is properly fitted and sealed, so you’ll enjoy consistent temperatures and quieter rooms. With strong materials and expert craftsmanship, your home will feel safer, warmer, and more welcoming year-round.
What styles of doors are most popular with Maryland homeowners?
Maryland homeowners often choose front doors with woodgrain style finishes for traditional homes or smooth, painted fiberglass for a modern look. Patio doors and screen doors are also top choices for creating open, airy transitions to outdoor living areas. Our design specialists help you shop confidently for doors that suit your home’s architecture while improving beauty and comfort. From glass panels that invite light to bold colors that make a statement, we’ll help you create an entrance that feels uniquely yours.
