"We put a second story addition on our home with Cityside. From our first meeting with Freddie, he saw our vision and from there made it come to life. Each one of his contractors were timely, honest, fair and professional. Mike, Freddie's team lead was knowledgeable and detail oriented. Our project came in on schedule and budget and just how we had anticipated in our original meeting. We would not hesitate to use Fred/his team again or recommend them to others looking for building/renovations."

"Nice owner, hack job crew. Hired to replace siding and trim. Manager of the project was fired a few times during work and it really shows. So many small details are either unfinished or poorly done. Amateur cuts on the trim left gaps and old trim was not prep for paint or just left unpainted. They also smeared silicone to cover screws on the front face of the shingles, the whole house looks like it's covered in bird droppings. Plus they also damaged the roof and electrical boxes. Who knows what other things they skipped on, left me with a time bomb of problems that will takes years to show. I would not recommend. "

"They was supposed to do kitchen renovation and they did not come and do any wall preparation before the cabinet arrival and also I had asked them questioned and they did not answer my email. I had shown photos of the wall inquiring how they wanted to proceed and their project management was keep in touch with the project to schedule. It should have been done cabinet installation door cabinet for arrival because all the cabinet and they've taken up space. I am a senior citizen and I have limited funds of that project. I am more disappointed that the project did not go well on both ends that they decided to keep my $2100 deposit. I they refunded most of my money back in good faith that I wouldn't have been disappointing. "

"John was incredible, so easy to work with! He handled every detail like it was his own home, he was here so often he started to feel like family! Our kitchen and bathroom remodel is absolutely stunning but John did so much more than that for us! A complete backyard renovation with a new patio too! 10/10, would definitely work with John again."

"There were super fast and friendly. Did a nice quick fix so I could use my gate. So thankful for their help!"

"I recently had Advance Guard build a new deck and replace my old wrap-around porch, and the results are outstanding. From the start, Dave was professional, knowledgeable, and passionate about his work. He listened to my ideas, offered valuable suggestions, and kept me informed throughout the process. The craftsmanship was top-notch, with great attention to detail. The new deck is spacious and beautifully designed, using high-quality materials. The porch replacement blends seamlessly with the new deck. The job site was always clean, and the project was completed on time and within budget. Dave was approachable, communicative, and dedicated to customer satisfaction, making the entire experience enjoyable. I highly recommend Advance Guard for any home improvement projects. The new deck and porch have transformed my outdoor space into a stunning area I'm proud to show off."
