Report
I would refer Atra Construction to anyone looking for a contractor. Dan was very responsive and helpful when discussing a construction project. He was very knowledgeable and answered any questions I had.

Report
I have worked with Dan since I bought my first home in 2006. Dan was able to provide shutters and blinds for our entire home and this is where this partnership kicked off. Since then, Dan has been able to assist with everything from a simple electrical fix to an entire home remodel. In 2020 I contracted Dan and his team to complete a full rental makeover. This included new hardwood floors, bathroom and kitchen remodel, HVAC updates, a new roof, and many other items needed to complete the remodel. Dan and his crew were always, clean, courteous and on time. Pricing has always been fair, and I know I can count on Dan to get job done.
