What our clients say
“City Builders redid our Canton rowhouse flat roof three years ago. Roger and his crew found and fixed a leak two other roofers had missed. Zero call-backs since. Forty years of Baltimore rowhouses shows in every detail.”
“We had a rooftop deck built on our Federal Hill rowhouse. City Builders handled the permits, the engineering, and the flat roof integration. Two years in, no leaks, no problems. Rare Baltimore expertise.”
“Got three quotes for our Columbia home. City Builders was the only shop where the owner Roger showed up for the estimate. Straight pricing, meticulous work, on-time crew. That old-school approach is why they have 40 years.”
