Dan and his team went above and beyond on our closed in porch and custom doors. They were personable, responsible, considerate and importantly, very talented! We are thrilled with the results and will be hiring them for our next renovation as well as promoting them to our friends and family.

I hired Dovetail Construction to replace the failing ceiling in my carport. Dan and Mario were always punctual and friendly. They listened to my request for a specific design esthetic and delivered exactly what I wanted. The finished product looks great and should last a long time. Site clean up was done every day and they were respectful of my property. I would recommend hiring Dovetail Construction for your project. I attached before/after photos.

The Dovetail team did an amazing job taking out our wall and putting in a recessed beam with a weeks notice. I couldn't be happier with how timely and professional the team was.

Hi hired Dan to do a total renovation with structural changes in my 110 year old Park Hill home. Dan worked flawlessly with the engineer who designed the structural change. His crew left the property clean and swept up at the end of each day. Dan and his guys were a pleasure to work with and they also made the job fun. He made sure every little detail was thought out and accomplished. After being a Real Estate appraiser for the last 30 years I have come across many “contractors” doing renovations. I’d say Dan and Dovetail Joint Construction stand at the top. Highly recommend. Ray Colaiano
