What Our Clients Say
“Dara worked with my family on a major renovation and gut rehab of the two-family where we live. This was a large, complicated project with a lot of different parts — creating a dry basement (which involved pouring a new floor and installing a French drain while keeping heating and hot-water systems running), work on plumbing, electrical, HVAC, carpentry, exterior stairs, restoring a second-floor porch, and more. Dara was totally effective in dealing with countless different subcontractors and coordinating all the work. He had a comprehensive plan for the project and saw it through on time, with minimal disruption to our lives, and with fabulous results. What had been a wet basement hasn’t had any problems even during major rains. Our house went from being the old one that needs help to being one of the loveliest on the street — because of Dara’s pride of craftsmanship and attention to detail.”
“Dara and his crew were exceptional! I would not hesitate to hire them for another job in the future. They created a finished room in our garage by building a second floor. Dara was excellent with communication and resolving any questions or changes/additions we requested. His crew were detail oriented in their job, they showed pride in their work, and were always friendly, courteous, and respectful.”
“If we could give Colleary Construction 10 stars, we would! Dara’s professionalism, organization, attention to detail, and genuine concern for our satisfaction was unbelievable. His crews were on time, on site every day, very skilled, and extremely considerate. There is no guessing with Dara, he is up front and transparent throughout the entire process and takes the time to make sure your questions are answered and everyone is on the same page. I could go on but honestly just do yourself a favor and contact him! Thank you for everything Dara! ”
