We recently purchased a home which had a potential moisture problem in the crawlspace. The home inspector we used during the purchase of the house suggested we reach out to a company that specializes in crawl space evaluations. We found three companies, and had each come out to evaluate and offer their recommendations. Clean Crawlspace was by far and away the most professional, the most knowledgeable and the most frank and honest. I highly recommend this company - Ask for Daniel, he was awesome! read more

First of all I highly recommend a vapor barrier under your house. It makes a world of difference especially with the health of the inhabitants. Please avoid doing business with this company though. Their installation is not up to par, their product is inferior to others, and their customer support post sale is horrible. They installed their product (which is not 20 Millimeters as advertised), in a timely fashion. They also installed two sump pumps. The installation looked fine, but when the rains hit, I had issues. The wiring to the second sump pump was just laying on the ground, so when one pump failed the whole system shorted out, and my crawlspace flooded. When they finally came out (which took 3 weeks), they said they weren't liable, and tried to sell me two new pumps, plus a dedicated circuit for $1500 more. The crawlspace barrier was only 3 years old. They went on to say that since I live in the south bay, and they were up in Santa Rosa, they would no longer support me. They said I should find another supplier. I still see their trucks in my area so I'm assuming they will sell you a new system, but then leave you hanging like they did with me. Please avoid this company. There are other suppliers of service, and a better product in the south bay area. read more

Clean Crawlspace gave us a free inspection when I was worried that we might have water damage. Florencio Chavez was extremely thorough when showing us the photos of what he had found and how he evaluated it. He demonstrated that we had nothing to worry about, as he showed us the plumbing, the sump pump, the ground underneath the flooring, and the house exterior. He showed us the outline he had made of the basic house floor plan and those areas with a small amount of moisture, but that he thought within normal limits. Unbeknownst to Florencio, those were the exact areas, we had recently discovered, where the previous owners had blocked the French drains and we'd had to have them re-done. He gave us advice on how to avoid future problems and to screen potential contractors for expertise and honesty. Florencio also offered to email us the photos and did so the next day. I was very relieved to have Clean Crawlspace's "clean bill of health" for our house, to experience no "hard sell", or even, soft sell, of Clean Crawlspace's services, and to receive helpful advice, in the bargain. Together with their great ratings, I think I could trust this company to do a good job should we ever need their help. read more

These guys were great. Responsive, affordable, answered all my questions. They even came back after the job to pick up some debris we had originally told them to leave alone. I really appreciated that. Would definitely recommend them again. read more

Clean CrawlSpace just finished installing three sump pumps, two dehumidifiers, treating our wood surfaces, and fully encapsulating our 2,300 sq/ft crawlspace. They did an amazing job. No more odor in the crawlspace and our air quality on the first floor is very noticeably improved. Working with this company was an absolute pleasure. Meshka handled the scheduling/billing and was extremely responsive, professional, friendly, and exceptionally easy to work with. Florencio did the inspection and did a very thorough job. He provided a detailed explanation (with pictures) of what was wrong, what needed to be done to fix our issues, and how much it would cost. Everything was well documented and very clear. The installation crews were top notch. Prompt, polite, respected our house & Covid protocols, and were amazingly hard working. After everything was done, I took a crawl around our space and I developed a new appreciation for Clean CrawlSpace, the service that they provide, and the workers that do the job. My thanks to the Clean CrawlSpace team and I highly recommend this organization. read more

Larry the sales person spent an hour under the house to determine what the need was. He quoted the price of the service, showed me pictures of the crawl space and described the installation in a professional manner. The installation crew lead by Raul was excellent. Raul developed a better solution to drain the output of the sump pump. They crew worked diligently and completed the job on time. Within a couple of days, moisture in the house palpably decreased. I can recommend this company. read more

Its amazing the difference the clean crawl space makes in our house. I am very pleased with the level of service we received. Alex the sales rep is very knowledgeable in construction and he explained the process and the benefit very well. The workers did an amazing job, they left our house cleaner than when they came. We now don't have to worry about mold growing into our house through the floors. I highly recommend the San Jose branch of clean crawl space. read more

We contacted Clean CrawlSpace at the recommendation of a neighbor. What nice people! Our first contact was with Sabrina who listened to our concerns about an odor in our home and immediately set up an appointment for an in home no obligation inspection. Within a few days Florencio came and crawled into our crawl space, emerging over an hour later with pictures, a map of the area, and list of issues that needed to be addressed. Wow! We were so impressed. He was so thorough. For the first time in many years, the lights "went on" in an area of our home we could never dream of crawling. The first step was to make the area environmentally clean for workmen. Florencio sent out Mariano and Isai to vacuum the crawl space and remove debris and loose/falling insulation. These nice men were so respectful of our property and answered all our questions, showing us bags of debris. We noticed a cleaner smell in our home within a day. Florencio's recommendations for heating and plumbing repairs has helped us avoid problems down the road. We are so grateful for his expertise. These guys are really pros. read more

We were very impressed w the service and results of Clean Crawl Space. Larry came over and did the free quote and was very personable and helpful. Barbara in the office was very friendly. David the manager came over and made sure that the crew was done on time and called us as we were out of town to be sure we knew they were on schedule. He even brought in a package delivered to our doorstep for us while we were away. As I am very sensitive to odors they obtained a negative air machine to run for a few days to eliminate any remaining odors. We were very happy w the results! read more

We had Clean CrawlSpace do mold remediation work, install a sump pump as well as the vapor barrier system under our house in the fall of 2016. As far as I could find, they were the only company who would do both the mold remediation work as well as install the vapor barrier system. I was impressed by their quick response to my inquiry for an estimate. Their sales person was professional and prompt in providing an estimate, and once they were given the "go ahead," they effectively and efficiently completed all phases of the work in approximately 5 or 6 days. We were impressed by the professionalism and work ethic of all the guys who worked on this project. One of the gentleman also alerted us to an issue with the duct work under our house, which were then able to get replaced. I highly recommend them! read more

This company went above and beyond on a holiday weekend. Our original sump pump, installed in 2005, started making noise. When the technicians came to repair it, they saw a broken pipe from our kitchen sink was spewing food from the garbage disposal all over the space under the house. When we couldn't find a plumber to fix the pipe, the owner found one of his employees to come out on the Saturday of Memorial Day weekend. He fixed the pipe, cleaned up and sterilized the space, replaced the broken pump and secured it with gravel. Based on all the work done, the price was very reasonable. We highly recommend Clean Crawl Space. The owner treated our job as if it were his. read more

A wonderful company to work with. Everyone from the office staff to installers were professional and efficient. We have noticed an almost immediate difference in the air quality of the house. Allergies are better and almost daily headaches are gone. Wish we had done this sooner! Not sure how it will hold up over time but for right now we are very pleased. read more

From the very first phone call to ask for help to the inspection and all the way through the work that needed to be done this company went above and beyond my expectations! Not only were the crew who did the work (and it is tough grueling work) incredibly friendly and professional they noticed other problems they saw in places I couldn't see and suggested other services/help I might want to look into that were outside the scope of their own company! It was clear that they wanted me to have the best long- term solution to all my crawl space related problems. They picked up a problem with my HVAC that am HVAC inspector missed! Saved me from big problems that would have quickly emerged. I can't say enough good things about this company ... they have integrity and an amazing work ethic. Best contractor I have worked with in years and I have incredible peace of mind knowing the quality of the work they did. Even other contractors I've had in to do other work have asked for the name of the company who did the work! read more

David Cideos was the guy who installed my crawlspace. I am not to happy with the product they installed. The installation were very unprofessional, not what it look like in the pictures. I've paid over 5k to cover walls and bottom crawlspace. Bottom is covered but some walls were just not covered. Cuts on the materials were very crooked on the walls and not covering some part of the walls. When i inspect the space they left some debris of dirt and silicon tubing tips. read more

Daniel, the guy installed the system for the house did come over and fixed the pipes, etc. The operation was pretty clean and he has been very nice. But I won't upgrade their rating yet, will need to see how David, the manager, handles our reimbursement issue. read more

Clean Crawlspace salesman Alex was able to explain and show pictures of what would be done. He took pictures under our house and emailed it to us so we could clearly see what was going on and the beginning of mold on our wood. The crew came and did an excellent job. They were also very polite. David the manager came over and inspected the crews work to make sure everything was done correctly. I highly recommend this company. I know my house is now safe from mold and water collecting under my house. read more

We live in Santa Cruz and just used them to dig some trenches, sump pump and encapsulate subfloor because of high water table, lots of moisture in subfloor. I gave them 3 stars waiting to see how this winter goes with water issues and if that resolves them, if it works Ill give them 4 stars. Work crews did good job and were nice. Only irritating thing was long wait for appointment and install ( took months) but it was the winter of the century around here and everyone was having water issues. read more

These men worked under our house for 5 straight days taking only a one hour break for lunch. They do an amazing job and it ends up looking just like the photos on their website. They cleaned up every day and were very pleasant to deal with. They stood by their bid even though it took longer than expected. I highly recommend them if you want your crawl space to be clean and dry. read more

They are not the cheapest but I suspect they are the best. Started with a thorough exam and photos of what was wrong. Plenty of options presented. An immediate estimate. Very prompt arrival to start the job and the guys doing the work were wonderful -- very pleasant and professional. I would recommend them to anyone -- just terrific. read more

I want to acknowledge David, Josh and team's effort in ensuring the job is done well, and right, the first time around. The team arrived on-time to my house, and acted friendly and professionally. The Clean CrawlSpace Encapsulation System kept away the musty odor caused by the wet soil. My heater and duct testing crews also complemented the job well done when they went under the crawl space to perform repairs. I am very glad to have chosen Clean CrawlSpace as the service provider to address moisture issues in my crawl space. I would recommend them to anyone who needs a moisture control solution. read more

I've got to say that I was skeptical of the promises made by Clean CrawlSpace but after living with the their product for a several months now I have to say I'm a true believer. The guys were neat, they kept things clean, and came when promised. They've been very responsive to a followup issues. My crawl space was a smelly mess and they did a terrifc job, highly reccomend them. read more

I couldn't be happier! David Carney and his company are amazing! I needed some work done including trenching, grading, lining the crawlspace and installing a sump pump. He was very thorough in his explanations and estimates. He also provided before and after photos which was extremely helpful. The job took about 4 days to complete (along with some HVAC work I was having at the same time by a different company). When I found out I needed a new furnace, David happened to be there when the HVAC guys were explaining the defects. He made sure they showed him as well. I genuinely felt that he was making sure they were not taking advantage of me. He always checked if I had any questions or concerns during the process and was available in case I did. Could I have gotten the work done for less money? Yes...but I would not trade the quality, experience, professionalism and peace of mind for anything. . I could go on and on....but you get the idea! Thanks! read more
