We asked Carlos to review our moisture control issue and the possibility of a French drain. He patiently explained what a French drain does, how it would particularly help our situation, and thoroughly answered all our questions. He went the extra yard and collaborated with a simultaneous plumbing project, and the result was perfect. We highly recommend Carlos and his hard working team. Carlos is very personable, quick to reply to questions, expert in his craft, and most inportantly, reassuring and patient every step of the way. Thanks Carlos!!!! read more

At the end of 2023, we finally joined the "homeowner's club"! Finally accomplishing this huge lifetime milestone also comes hand in hand with being in charge of work and upkeep! We knew that there would be few projects and maintenance but man, oh man... you really do end up putting so much time, energy, and money into your house! We've been putting off our biggest project for last and that was finally getting a French drain for our water seepage problem. We live on a hill so once there is any rain, the influx of water really floods our foundation and it was seeping into our garage and crawlspace. I had 5 different companies come and give me their thoughts & estimates and once I met Carlos from Drainage & Moisture Control, I knew that he definitely was an expert. He was super knowledgeable and thorough and I just felt good genuine vibes from him. Out of all the estimates, Drainage & Moisture Control was the most professional & detailed. Although they were on the top end of our budget, we went with them because we felt that it was worth the extra spend for high quality work. We definitely chose the right company because Carlos & his team worked tirelessly, were so respectful to our family, and kept the work area so clean during the entire project. Communication with Carlos was super easy and we had updates on the progress daily. The team even went above and beyond and helped make a cement step for us, even out some of our uneven ground, and replace some of old broken vents! Wow! I was soooo impressed! I was ready to give them 5/5 stars for all their hard work on the French drain but now I wish I could give them 10/5 stars just for being sooo amazing and pleasant to work with!! Thanks again Carlos & team for helping us finally fix our last (hopefully) big project for our home! read more

I'd met with multiple contractors to look at my backyard drainage issue. Each gave their opinion. The main reason I hired Carlos was that he took the time to really explain the process during his consultation. And even during the work he explained things, too. Understanding what was happening, in plain English rather than contractor-speak made me feel much more comfortable about hiring him. Carlos sent his estimate pretty quickly which was also a plus. Though my issue wasn't complex, I didn't want to skimp on something this important. At the same time I didn't want to overspend on an overly complex design. Having met multiple contractors, I'd gotten a sense of the range of options and pricing. Carlos wasn't the cheapest nor the most expensive. I felt his solution was thorough and the right one for us. And at a reasonable price considering what he was doing. My opinion on the thoroughness was confirmed by someone who knows a lot more about drainage than me. He saw it on day 4 of 6. He told me he was impressed at how Carlos designed the French drain, too. read more

We called Drainage and Moisture Control after ten years of dealing with a constantly wet and hazardous driveway and seepage from the hill behind our around our house. Carlos responded promptly to our inquiry and after assessing the situation, prepared a detailed proposal at a very fair price. Carlos is knowledgeable, experienced, and passionate about his work. He treats each problem as a unique challenge and takes great satisfaction and pride in a job well done. Carlos treats his team like family. They work hard and joyfully and were a pleasure to have around for ten days. We are very pleased with the finished product and already feel relieved to know we will have a drier and safer environment. We highly recommend Drainage and Moisture Control. They go above and beyond. read more

We own a large, old Victorian in San Francisco and have dealt with recurring drainage, leak, and mold issues in our basement for the last three years. After a failed waterproofing attempt with another company, we were incredibly cautious in selecting a new team to help us fix this once and for all. Carlos and the team at Drainage & Moisture Control absolutely exceeded expectations. From the very beginning, the experience stood out. Carlos provided a free estimate that was incredibly thoughtful, detailed (including which products he would use), and comprehensive. We received five different bids for this project, and Carlos' was by far the most nuanced, sophisticated, and solution oriented. Carlos and his team are experts who know how to tackle challenging drainage and moisture issues. Throughout the project, they were consistently professional, communicative, and considerate. They cleaned up the job site every day and even blew the leaves out of both our front and back yards (not even part of the job site!) on their last day which was a totally unexpected but much appreciated touch. They finished the project on schedule and Carlos even went above and beyond by fixing our kitchen sink while he was on site as he knew we were hosting a big party the next day. That kind of care and generosity is rare. The finished work looks fantastic and most importantly seems to have fully resolved our longstanding drainage issues. read more

Carlos is very responsible, very flexible, he knows what's the best material to use to fix the problem. you could tell he likes his job .you tell him the issue and he works with you to try to keep the cost down instead of hiring it. I would call him again. He gives you good advice and how to maintain the problem. read more

We just had Drainage & Moisture Control install a french drain system and sump pump in our lower level and the team was attentive and professional. Carlos walked us through each step and offered us some useful tips along the way to maintain the system. You can tell he wanted to get it right, and not just check a box. I would highly recommend them for anyone struggling with chronic moisture! read more

I recommend Drainage & Moisture Control 100 percent. He fixed a moisture problem. He has a license CA #1124677 and is specialized. They explained the process and types of materials He has another license B general contractor CA #1051611 that gives him a more complete idea and how to fix moisture problems. I will definitely hire him to fix other properties that I have for rent. Thank you Carlos. read more

Carlos and his team were great! We spoke with four trenching companies, and while their prices were very close to each other, Carlos was professional and detailed in his scope of work, so we chose him. During the project, we saw how hard his employees worked, including Carlos himself. His sons, who also worked with him are smart, considerate, hard working, and polite. His crew always had big smiles, and Carlos was always available when we had questions. Our French drain system was installed, and we are very happy with his service. read more

Like a lot of houses in SF, our house sits against a hill, and the lower floor's back half is below grade with a retaining wall at the rear. When the intense flooding rain storms hit the past couple of winters we were dealing with water intrusion along that wall. After another contractor installed a sump pump, we discovered it did nothing and we still had the same problem last year. After speaking to a lot of contractors, Carlos came by and explained why the other solutions wouldn't work, and came up with a plan to address our drainage issues. We now have a perforated drainage pipe installed down at the proper depth to catch the moisture, a moisture barrier directing any seepage down in the pipe, and a new sump system taking it all into the sewer. They even installed moisture triggered ventilation fans, and took care of bringing down (and putting back up) the drywall in the utility room with the retaining wall (something most other moisture control companies wanted us to find a separate contractor to do). I now feel confident that we have the problem solved and highly recommend Drainage & Moisture Control if you are having similar issues. read more
