Sump Pump
Yasmin B.

We had an incredible experience with Miguel and his crew. His prices were extremely reasonable for the quality of materials in the workmanship. He was extremely thorough in explaining to us the options available and the benefits of encapsulating our crawlspace. His crew came at 8 AM and we're finished by 6 PM. They made sure to cover the floors so that they did not leave a trace of dirt behind. They were extremely professional and I couldn't be more pleased with the service. I noticed looking through my vents That one of the ducks were not secured properly and he came right away and took care of it. Very happy with the service and the product received.

BAMC just finished encapsulating our crawl space and updating our 2 old pumps. Bill was the one…read morewho came to take a look, and he was fantastic to talk with. Our house had a mish-mash of prior attempts to mitigate water under the house, and I felt good that Bill fully understood the complexities of the existing situation and offered a couple of solid options to deal with it. We did end up choosing the full encapsulation (to just finally be done with the issue) but I did not feel pushed in that direction at all during our conversation. Once we decided, working with Gina in the office and Bill to get the details of the plan finalized was easy, we got our dates locked in, and on the scheduled days Antonio and crew showed up on time and cranked through the job. Everything was finished exactly to the plan Bill had drawn up, including the interface to the existing parts of the system we wanted to keep. And the crawlspace looks incredible - truly a major upgrade to our home. Looking forward to a rainy season finally not worrying about it!

We hired Bay Area Moisture Control to install a sump pump with trenching to address standing water…read moreunder the house. On the positive side, the crew (Antonio) was punctual, easy to work with, and efficient. The whole job took 3.5 hours. The issue came with the placement of the sump pump discharge location. I had talked to their sales lead (Bill) about having the water be discharged to the street where there is a storm drain. Instead, the sump pump "pop up" was placed 8 feet from the front of the house, way too close. Water can flow back under the house, defeating the purpose of the sump pump entirely. When I called Bill during the job to talk about our options, he dismissed our concerns and immediately pointed to the contract, implying that this was our fault because we signed the contract. In reviewing the contract, the design was completely unclear about where the sump pump would exit water. Bill continued to skirt the fact that that we had discussed pumping water to the street, and instead, he baked a different design into the contract with unclear markings. We are dissatisfied with the poor communication, but even more so, the lack of accountability from the company. If you hire this company, just a word of caution to walk through the design with them before signing and make sure you're on the same page about everything. We are going to have to bring someone else out to fix the issue. One more thing ... I was flabbergasted that when talking to Bill on the phone about the iffy sump pump discharge location, Bill was trying to upsell me on encapsulation! Read the room, dude.

When buying our new home I opened the crawlspace hatch to check the framing. I noticed the dirt…read moreunder the home was mud. Could smell the heavy dampness in the air. Framing looked fine and saw no mold. After purchase I looked for companies to add a 20mil vapor barrier. My neighbor used clean crawlspace years before so added them to my quote list. I was a bit shocked by the high price but they were the best company I talked with. They did the most thorough quote - spent a long time crawling under the home. When they started the install and I saw what they were doing the quote made more sense. Crawling around in an 18" crawlspace unfolding first a "rigid mat" and then rolling out the 20mil barrier over than and sealing all the seams and attaching it flat against every wall of the foundation. I had insulation, hvac workers and myself crawling over every inch of their work and nothing tore or came loose. Could also see they attached everywhere. Even center 4x4 support footings were carefully attached all the way around. My only quibble is the liner has a rather strong industrial odor that is taking quite a bit of time to dissipate but this is beyond their control. If you want the strongest 20mil it will smell industrial for a while.

I selected Clean Crawlspace over their competitor Bay Area Underpinning due to price. They were…read morebooked out so I had to wait a few months until they could perform their work in two phases, but it looks like they did it good and at a fair price for my home. The service requested was up to my standards with them taking a couple days during each phases and displaying professionalism as they did their work. They were also helpful in providing a couple references for a local plumber and electrician that both knew their stuff and quoted me a fair price for the additional work that had to be done. I would highly recommend giving them a ring for your crawlspace needs and feel like I got the product I had purchased.
