Martinez Construction

These guys are rock starts and saved the day by completing our new lateral sewer line. The team and owner (Dave) came in on a mission to get the work started and completed. I've never seen a crew that worked like a well oiled machine. I can't rave enough on how professional, honest and pleasant this company was to work with and I would gladly recommend them to anyone who needed a new lateral sewer line. I know you can only give 5 starts but these guys are on top of their game and know their trade, from getting permits, excavating the site, meeting OSHA requirements, back filling, repaving, and at a reasonable price.

Had a sewer back-up issue that needed immediate attention. Dave Martinez of Martinez Construction was refereed to me by my typical Contractor that was too busy. Contra Costa Co. Sanitary District also spoke highly of Dave. He got the permits quickly and arrived at the Danville job site in two days! He and his crew understood the complicated problem quickly, and finished digging, fixing, and filling the two broken parts of the sewer line before the end of the day!His pricing was fair and his crew was hard working, coordinated, and well informed. I know I won't have to worry about this sewer line ever again!

Dave and his team did a great job with our septic conversion project getting us connected to the sewer and decommissioning our septic tank. They got the job done in a timely manner and left the yard looking as good or better than they found it. They were also the most reasonably priced estimate we got by far.
