Why Homeowners Trust C. Brennan Construction Inc.
Finished basements that add real living space — done fast, done right, within budget
“We had our basement finished with C. Brennan Construction. They worked hard and finished in under a month — and it’s beautiful. Chris answered every call, every text, and handled every request. Price was extremely competitive. We’d be happy to be a reference.”
“Chris turned our dark basement into an extra floor of living space — family room, office, bathroom, and gym (~1100 sq ft). He stayed within our budget, was flexible with changes, and made sure everything was 100% right. Outstanding customer service.”
“The inspector said the workmanship was from experienced people. The crews showed up exactly when Chris said they would, were respectful, and the quality was excellent. Finished on time — our new basement looks great.”
