Building Excellence Since 1934

Clients are front and center at Downes Construction and have been since we opened our doors in 1934. What began as a family business and continued to grow for three generations has evolved into an Employee Stock Ownership Company (ESOP) with 60+ employee-owners.

 It still feels like family here and we continue to tailor our approach to each project, drawing on comprehensive core construction services enhanced with in-house and specialty consultants to resolve complex challenges and deliver smart solutions that optimize the value of your construction dollars. 

We are committed to maintaining the highest standards of quality, performance, and integrity and bring a reputation for collaborative relationships with all our clients, colleagues and partners. Our work throughout Connecticut and Rhode Island includes projects for hospitals, corporations, municipalities, public and private schools, colleges and universities, museums, non-profits and several others. 

Every single team member at Downes is invested in your success. As we approach our 90th year in business, we look forward to delivering the trust and expertise that have made Downes Construction a partner in building excellence since 1934.
