In our 28 years of experience, we have never encountered a wet basement, crawlspace encapsulation or mold removal condition that we couldn’t handle. Give us a call today for a free, no obligation inspection and professional basement waterproofing system tailored for your home or commercial project. AA Action Waterproofing is licensed, insured and bonded with a A+ Rating with the BBB. Please call us and we’ll happily supply you with references.
"Our 25+ year-old French drain system in our 100-year-old basement was showing signs of failure, so we contacted several companies to get advice on what to do. Jason of AA Action was very professional and helpful when he performed his initial inspection of our basement, and had very good ideas on what needed to be done. The price he quoted for the work was also, based on what we had read, reasonable. We ended up going with another company recommended by Angi, but only because it brought up a couple of options that we had not thought of, and we felt comfortable with them doing the extra work. We were not at all unhappy with AA Action's suggestions or pricing - it's just that the other company's additional ideas made sense for our circumstances."

Additional DBA - JCF Inc .
"Jimmy showed up to my home during a time when my thermostat was not working. That issue was fixed. He sold me a services contract and told me when he returned to services the units, he will cover the pipes outdoors. I purchased the contract for twice per year maintenance. I scheduled with him for a specific date. Appointment was confirmed but Jimmy did not show. When I called, he it appears that he forgot my appointment and he rescheduled saying he could not work in the rain. He rescheduled for a few days after and one of his workers showed up (Carlos). The guy showed up looking like he was someone who does not want to work and unprepared. So, I asked him if he has filters and he said know. Jimmy's workman did not bring filter, so I offered him filters I had stored. I asked him if he bought things to cover the pipes at the back, he said no. I called and left a message for Jimmy. Carlos was so rude and unprofessional. I was so scared of him and the way he was behaving. Carlos then said he would NOT do any service. IT WAS A WASTE OF MY TIME. He did return my money. BUT I will not recommend him. Will NOT use him again. As woman I will not hire again. Customer services was poor, reliability and punctuality poor."

"JES Foundation contracts all their electrical work out to Root Electric. In the process of installing my new sump pump, back-up sump pump, and sump pump alarm system, it was determined that a new dedicated outlet could not be created due to my existing electrical panel being too small. Thus, I needed to get an electrical panel upgrade. Through JES Foundation, a date and time was arranged to have my new electrical panel upgrade installed. The lead Root electrician Andrew, and his assistant Andy, dd a terrific job installing the new upgraded electric panel. They were both very friendly, efficient, and professional.

Yes, most states require plumbers to be licensed, and for good reason. Hiring an unlicensed plumber could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
The cost to finish a basement is $18,400 for the average homeowner. However, this cost could be as little as $2,800 or as much as $34,500, depending on the basement size and the materials needed. If your basement is already outfitted with electrical and plumbing, expect the cost to fall on the lower end.
For example, the drywall cost for this project averages around $1,750, but other features, like hiring a plumber, cost between $45 and $200 per hour.
The cost to remodel a basement is between $12,100 and $33,400 for the average homeowner. The price you pay can be as little as $3,500 or as much as $50,200, depending on the size and condition of your basement and the type of remodel you're doing.
If you're doing a simple project like adding a home office to your basement, you can expect to pay anywhere from $500 to $3,000. However, if you're adding a bathroom, which is an extensive project, you can expect to pay between $6,600 to $16,500.
Foundation repairs cost about $5,000, on average. Typically, prices range from $2,200 to $7,800, depending on the type and extent of repairs needed. Cost factors include foundation type, home size, soil stability, accessibility, and the ultimate cause of the problem and what methods and materials are required to fix it.
The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in.
If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
