    "Mark and his team at Custom Design and Build were wonderful. Mark walked us through the order process, kept us in the loop throughout the entire assembly process, and installed our Alutech retractable awning ahead of schedule. The finished product is perfect, exactly what we wanted and expected. Can't say enough about the experience. We highly recommend Custon Design and Build."

    "Highly recommend Custom Design and Build. They screened in our front porch and it looks gorgeous! All windows made to size, really nice clean work. I've never seen the window system they use. It's very cool. Windows easily come out to make full screen. Mark and his crew were great to work with. Great looking work."

    The No-Sale Review

    "I wanted to take a moment to thank Mark for his time and effort in providing my wife and I a very detailed proposal/quote. From the very beginning of the process Mark was very responsive and honest about what was required for our project. It was very refreshing to have a contractor actually return our calls, show up on time for our appointment, answer our many questions and explain in detail what we could expect from him and his team. At this time we have decided to postpone our project but we will definitely be calling Mark when we are ready. We will also be recommending Mark and the Custom Design and Build Team to everyone we know. Thanks again Mark and we look forward in working with you in the near future!"

    The Full-Disclosure Review

    "I recently had some deck work completed At my home in Harford county . The work was Excellent and fairly priced! We compared with other service providers in our area prior to hiring. … I recently purchased a dog and we were looking for a fence contractor for security and something that looked nice for our property. We reached out to mark once again for some recommendations fence types Etc. Mark was very thorough as always and knowledgeable of codes with Harford County needed for a fence installation. … I will note Mark's price was comparable but a little bit higher than the other companies in the area. I have no regrets of using his services for a second time was well worth the money and the wait to get on his schedule."

    The Re-Do Review

    "Mark ans team were fantastic to deal with. They took my weird piece of land and turned it into a stunning piece of landscape. I get comments from every person that comes to my home. We had no idea what to do with it, and they came with ideas, made adjustments in the middle of the project if something wasn't working, and re-did any piece we were unhappy with. They treated the my project like it was what they would want their home to look like. I would hire them again for any work I needed done."

    The Contractor's Review

    "I would absolutely recommend Custom Design Build to anyone. Mark and his staff installed an aluminum ceiling under my deck and did a wonderful job. I've been a commercial contractor for the pass 41 years and I can be very particular. From contract to completion, Mark is truly a good guy to work with. …"

    Project: Aluminum ceiling under a deck

    • Reviewer: commercial contractor, 41 years
    "It was a pleasure working with Mark, Viola, and the entire team. All phases of the project from the initial phone contact to project completion were executed professionally and timely. We started with a wooden deck and screened enclosure that was rarely used and ended up with a beautiful composite deck and sunroom that we enjoy daily. We greatly appreciate the skilled craftsmen and specialty tradesmen bought into the project to ensure the final result not only met Mark’s expectation but more importantly ours. We now have an additional living space to enjoy for years to come!"

    "Loved working with Mark and his guys! Love our new sunroom even more! Mark was open and honest from the very first call (& never salesy) He was a great resource in helping us finalize the design and recommending a few changes we would have never thought of. After our terrible experience getting a pool two summers ago it was very refreshing to work with a company who did what they said they were going to do and were on schedule! Highly recommend CDB"

    "We had a fantastic experience working with Mark Szabo and his team from Custom Design and Build. Our deck of 35 years needed to be replaced and he came highly recommended. … Communication was clear and consistent, and the deck was even completed ahead of schedule and in less than a week’s time. His crew was hard working, meticulous in their work and clean-up, and very respectful to us and our neighbors. …"

    • Reviewer: done in less than a week, ahead of schedule
    "I have used Custom Design & Build for several projects over the past 4 years including a deck, a patio and a fence. Most recently I need to have part of my fence taken down and moved as part of a larger project that involved several contractors. Mark’s team was accommodating with the multi phase project, they were here when they said they would be and did an excellent job. I will continue to use them for future projects."

    "Mark is extremely professional and he and his team do excellent work. Mark assists in planning, keeps in communication, and is friendly and personable. My deck is beautiful! A pleasure to do business with Mark and this company. I am updating my review only to reiterate how awesome Mark and his team are. I am having a problem with my home that is completely unrelated but in close proximity to the deck that this company built and Mark and Louis still came out to my home to support me in reviewing the problem I am having. They know what they are doing and do it well. Professional and nice guys besides!"
