One Stop Shop Construction
We pride ourselves on our quality workmanship and customer service. Although most of our current projects are commercial buildings, our business was founded doing home repairs and remodels. Oscar Salas, the owner, treats each and every property as if it's his own, which shows in the finished product and satisfied customers. Because of our stellar reputation, One Stop Shop Construction was able to survive the economic downturn (2012-2014) by doing business with repeat customers and referrals to their friends and family. There is no job too big or small, as we believe that happy customers will continue to return as their needs change/evolve. Although located in Martinez, we have done business in Placer County, California and Ashland, Oregon.
If you are looking for the least expensive contractor, we are probably not the business for you. However, if you are looking for fair-priced, high-quality, high-value workmanship with an excellent reputation, please give us a call for a free estimate. We encourage you to ask for and contact references with any contractor you are considering to do work on your property.

One Stop Shop Construction is my go-to contractor for all jobs big and small. I know that they do a ton of commercial business, but they also specialize in home repair and remodeling. They are not the cheapest, but they are the best. The owner, Oscar Salas, treats every property that he works on as his own. I have referred them to all of my friends and family. -m.s.
