“Recently my wife and I had our bathroom remodeled by the pros at Promax Construction. We couldn’t be more pleased. The work was beautifully done, with top quality products that yielded very impressive results. The workers were always on time and very conscious of protecting other spaces in our home to minimize dust and tracking. The craftsmanship of the project exceeded our expectations along with coming in on budget, on time. My wife and I would encourage you to check out Promax Construction for your next remodel. I know we always will.”
