I would hire Jessie and his crew from EM Construction again and again. They have exceeded my expectations. I had a different company rebuild a shed and plumb it for a washer and dryer. After many, many mistakes and 2 months later the project was still not completed. I saw EM Construction working at a neighbors house and inquired if they could finish the job. Jessie and his crew completed the job in 2 1/2 days. New roof and flooring installed with correct plumbing for washer/dryer and a whole house water filtration system (plumbing had to be completely redone). New steps and reinforced deck with redwood railing was also completed. Trying to repair someone else's work is never easy but these guys did a fantastic job. They showed up when they said they would and left the property clean. I plan on hiring them again for a bath remodel in the future.
