Resident #204 | Boylston-Howell Apartments

As the owner’s representative for Capitol Hill Housing, I worked with a number of your staff: Terry Buchanan as project manager, Dennis Buchanan as estimator, and Kevin Engelhardt as the project supervisor. In every instance, I found them to be responsive, creative, and eager to get any particular problem resolved properly, quickly and fairly. It was a true pleasure to work with such a professional and caring team: the quality of workmanship, the dedication to doing the right thing in a timely and cost-effective manner, and the personal responsiveness of the Buchanan team have combined to make this a truly successful and memorable project.”

Lee Stanton | Owner’s Rep | Stanton Associates

They have strong working relationships with their subcontractors. We are happy to recommend Buchanan General Contracting Company and look forward to the opportunity to work with them again on future projects.” 

Roger Tucker AIA, LEED | Executive Director | Environmental Works

“The entire team has demonstrated professionalism, quality workmanship, and excellent communication in addition to adhering to schedules. Staff remained on site during the upgrades and all remarked as to the contractor’s commitment to their safety and needs. Buchanan is an important asset to our projects, and they set a standard to which all contractors can aspire.

Vickie Stark | Project Manager | Tacoma Housing Authority

“I’ve worked with Buchanan General Contracting Company on two state-funded affordable housing projects – one renovation of multiple apartment buildings and the other, a modular tiny house village. In both cases, Buchanan was brought on prior to construction to provide pre-construction services including scope analysis and estimating. These projects would not have been able to happen without their support, expertise, and timely advice.”
