My listing needed a new sewer lateral but trenchless was not an option due to a change in Central Sanitation not allowing trenchless under slab. Home was built in 1949. Huge job with the potential for severely damaging plants and the patio and not having the required slope. Not only did Dave accomplish this difficult job on time and on budget but the patio and plants were not disturbed at all. The yard looked better than it did before this job. Great price too! read more

I was referred to them by another plumber. Brought them in December '24 to reroute my sewage out under the house (crawl space) under the foundation and pavers to my septic tank. The team/crew was fabulous. Dave was great at explaining everything and the team did precisely what Dave said would be done. I had a significant amount of trust when the team showed up. They ran through the game plan and discussed everything with me. Started at 8am and done before 2pm. I checked in on them a few times during the day in case they needed anything but they were good. The pavers, dirt, patio area was spotless when they left. I am so happy I was referred to Dave! Just a great experience! read more

Their work ethics, experience and pricing is incomparable to all 5 plumbers I have asked around. They work diligently and swiftly. Dave is the man for any serious sewer lateral replacement. I consider Dave and his crew as a blessing who has done the work at our place in Pacheco. read more

Dave and his crew did a truly remarkable job fixing multiple holes in our 70 year old sewer line. All digging was done manually so our yard would not be torn up prior to listing our house for sale. They did such a thorough job, each worker was respectful of our property and their cleanup was better than almost any other service provider I've ever used. Knowing we had a time crunch, they squeezed us in and had 4 guys working for 2 days. And although the job ended up being more complicated than originally thought, Dave's bid was extremely reasonable. I can't recommend Dave and his crew highly enough. read more

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.

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! read more

Dave was referred to me by another realtor who had used him before. We just used Dave on sewer lateral replacement in Pleasant Hill. We could not do trenchless due to the angle of the existing sewer pipe. We had quotes of 12k and two weeks before the work could be done but Dave came in with a 9K bid and the work started within a few days and was completed in two days. This included digging a trench, ripping up and replacing the sidewalk, redoing the existing plumbing under the house so it would code compliant, cutting an existing french drain and sprinkler lines and repairing them and making them whole again and all with city permits. I would recommend him to anyone. Simon Watson KW Realty read more

Dave and his team did a great job with our septic conversion project getting us connected to the sewer and decommissioning our septic tank.

We decided to go with Dave Martinez for our 1940s house clay pipe sewer lateral replacement as his price was the lowest after checking that he has been in business since the 90s, has had concurrent insurance/bonding since then, and has no bad reports on Better Business Bureau. Overall I am very pleased with the outcome. He gave me a firm written quote that priced out the work + a fixed allowance if the Wye connecting the line to the Main in the street needed to be replaced. Despite problems only discovered after digging. He KEPT HIS PRICE and only invoiced me the quoted amount. He thought it would be 1-2 days and it ended up taking 3 because of two issues: (1) When breaking out the concrete from the master bath line connection, they ended up cracking the pipe (just the way it goes sometimes, I don't think they were being careless), so instead of just swapping out the cleanout for a 4" line (from a 3") for the permit, they ended up running the line trenchless from them master bath in back all the way out as the lateral and connected the previous point to it. (2) Also, the line when complete had a belly and the inspector did not approve it. His men took another day to excavate next to my driveway (instead of cutting into it) to bolster up the line. After this work, it was approved and he sent me the permit/certificate for my records. On the downside, the guys weren't really good about communicating what they were doing, why it was taking longer, when it would be done, if there would be cost impacts due to the issues. I worked from home during the days so I overheard a lot of it in Spanish, but wasn't really sure until the end how it was going to turn out. But what they lacked in communication, they made up for in skill. Only 2 squares of sidewalk had to be demo'd and were replaced looking great. The road was well repaired. And he only charged me what he quoted. I would happily recommend Dave Martinez again. read more

Selling an old piece of property in cities such as El Cerrito, Kensington requires rebuilding a sewage lateral. After construction of the lateral, the letter of compliance from EBMUD is needed to complete the sale. The price of getting the whole package which includes permits, retrenching, repavement and inspection varies a lot among contractors. Often times, they may need a video to scope the lateral before any estimate. In reality, it is not needed since the clay pipe in most of those homes will not pass the pressure hold test even if the sewage works fine. I was fortunate to find Martinez construction. Much of our negotiation was done by phone and e mails. The owner gave me a very competitive price. He was pleasant and easy to work with. He and his crew finished the job in two days. read more

After 52 years, our deteriorated root-infested 85 ft. sewer lateral in Lafayette was pretty shot. I got 3 free camera inspections and 5 written bids, all higher than what we thought was reasonable. I called Dave who came over in a few hours. I told Dave that unless I got what I regarded as a reasonable bid, we would just snake the line out again and "limp along" for a couple more years. Dave gave me a straightforward all-inclusive bid for complete trenchless replacement for about $2000 less than most of "the competition." With the holidays rapidly approaching and guests arriving in days, Dave promised to get the job done in two days, including inspections. He delivered. The County permit fee ($660!) is a total rip off. Under the circumstances, it is almost a pay off to the mob. If the City of Lafayette encroachment permit is also required that's another rake off. We narrowly escaped the latter. In the Bay Area the county permits turn a six hour job into a two day or 3 day job with all the inspections and wasted time. It's a shame. All homeowners pay dearly for it. But at least Dave got it all done efficiently and took care of everything. Replacing your sewer lateral under the lawn hardly gives you bragging rights. But at least Dave mitigated the pain and delay, and we can rest assured that we will never do this job twice. My only small misgiving was that some soil removed had to be hauled away instead of compacted in the ground due to the rains. I trust that if we wind up with a small depression on either end of the pipe due to settling of the soil, Dave will follow up as promised to bring in a bit of soil and tamp it down next year. I will follow up to this review if it doesn't pan out as expected. read more

Dave has been promising for almost a year now to pay for our bistro lights his guys took down during a job. They disappeared and Dave said he would take care of it. All promises, no action. Dave I suggest you contact the home owner in Walnut Creek ASAP as she will be reimbursing us and you have to go through her now. read more

We needed to replace our sewer lateral, and Martinez Construction gave us by far the lowest of five bids. It was so low, in fact, that we were hesitant about hiring them. (We subsequently learned that at least one of the other contractors would have lowered their bid $2000 to match it.) Dave was extremely accommodating and was able to rearrange his schedule to squeeze us in, and the work and all inspections were done in two days. I can't say we love our new sewer line ;), but we saved some serious money and have no complaints about the process. read more

We just bought a house in Concord and during inspections found out the sewer had some serious root intrusion out into the street. Thus, the whole old clay system needed to be replace. Thankfully, the seller eventually did credit us for most of the work. We had ended up getting three quotes for the price to fix the whole thing. Initially Martinez Construction came tied for the highest bid, but they are a pretty solid company and are licensed and provide workman's comp. The lower bid place did not provide that for their "independent contractors," which I usually steer clear from. Additionally, Martinez construction was referred by my realtor, who had yet to steer us wrong, and he said they did quality work. The owner Dave was really great. He took the time to talk with us regarding our options and explained the process beautifully. In the end, the price they gave us was the one to beat. He was aware of how much the sellers gave us for the replacement and significantly dropped the price in order to work with us, so we only had to pay a little bit out of pocket. He also tried to get the work done as soon as possible, but the rain gave us a bit of a delay. He had the whole thing done in a little more than half a day, but needed to come back the next morning to finish the asphalt patch. As far as I know, they did everything right, quickly, and for a good price. The inspector signed off on it fine and everything was left in good condition. So, all in all, I would recommend this company and I have to say that Dave is a really great guy. I don't know why they have not been reviewed on yelp yet, but I thought I had to do it becasue I am always using this site to find people who are not going to screw me over. Also note that as of my posting this, the website link under the buisness name on this site is not right- it apparetnly goes to a southern CA company. read more

The top of our septic tank collapsed. We originally thought we could fix the top but unfortunately the city would not let us repair the tank since we were within 300 feet from the city sewer line. We had to abandon the septic tank and hook up to the city sewer. I contacted 1 company that took over 2 weeks to provide a quote. Since the company was slow, I researched other companies and found Martinez Construction on a document provided by the city. When I called Dave, he was in our neighborhood, checked out the tank and provided a quote within 24 hours. He was very friendly, professional, and provided a thorough explanation of the project. We scheduled the work and within 1 1/2 weeks, the work was complete including permits and inspections. I was very happy with the work he did. The lawn was relaid and the cement area he opened was replaced very nicely. In addition to his quality work, his price was extremely reasonable read more
