“I'm a first time home owner in Baltimore City. First thing I had done was having my main front window replaced. I talked to Nick on the phone, told him what I needed, and he was super courteous. He made me feel like we were old friends. His crew showed up exactly when they were scheduled. Will definitely use this company again.”

Jonathan Peak⭐⭐⭐⭐⭐

“From start to finish, Nick (the owner) was incredibly responsive, professional, and easy to work with. He took the time to answer every question, explain our options, and made sure we were comfortable throughout the process. The installation team was outstanding - extremely detail-oriented and clearly took pride in their work.”

Jon Yantz⭐⭐⭐⭐⭐

“We had Nick install 18 windows and 2 sliding patio doors in our home and we are so happy with the result! Nick was amazing to work with - super helpful and always happy to answer any questions we had. The installation team was so professional and detail-oriented.”

Kelly Yantz⭐⭐⭐⭐⭐

“Nick and his team were great. Super responsive and got someone out to replace the fascia that became detached from our house. It looks perfect now and was a super quick, easy and seamless process. Will absolutely be using them again!”

Melissa McMahon⭐⭐⭐⭐⭐

“I worked with Nick from Next Phase Exterior Remodeling on my window replacement project and couldn’t be happier with the experience. He was extremely knowledgeable — walked me through different product options, explained the pros and cons clearly, and helped me make the right choice for my home.”

Brad Betson⭐⭐⭐⭐⭐

“I reached out to Nick from Next Phase Exterior Remodeling for help with windows on a couple of properties I manage in Baltimore, and he was a huge help. He really knows his stuff — from understanding older city homes to recommending products that fit the look and structure of the neighborhood.”

Ian Wall⭐⭐⭐⭐⭐

“Nick was a pleasure to work with and truly knows all things Windows and doors! The process was seamless and he communicated everything up front. I highly recommend NextPhase for your home exterior projects.”

Melissa Betson⭐⭐⭐⭐⭐

“I had a great experience working with Nick. He responded quickly to our inquiry, gave a fair estimate, and was able to start work quickly on our window replacement. I would highly recommend him to others and look forward to doing business again in the future with him.”

Tight Lining MD⭐⭐⭐⭐⭐

“Nick and his crew were great to work with. We had some urgent issues with our home that needed immediate attention. Next Phase was out ASAP working on it and fixed all the work our previous roofing company installed incorrectly. Will be sure to use Next Phase again! 👏🏻👌🏻”

Rob McMahon⭐⭐⭐⭐⭐

“I had major siding damage at my house. Nick and his team got it fixed and the whole experience was excellent from start to finish. The pricing was very transparent, and communication was great throughout the project.”
