"The technician examined the basement and determined that the water was likely not coming in because of a problem with the foundation but because of a leak somewhere and advised us to call a plumber. Highly ethical behavior."

"They did an excellent job of waterproofing our foundation, burying downspouts, and replacing a patio to guarantee drainage away from the house. Most of our interaction was with the crew foreman. He spoke good English, showed attention to detail, and did a careful, professional job even when the weather got so hot we found ourselves urging the crew to take more breaks. They were not the cheapest bid, but worth it for the skilled workmanship. This is the second project we have hired them to do, and I would recommend them for any work where drainage is important."

"I recently had the pleasure of working with Oswaldo and his team for a foundation repair project, and I couldn't be more impressed with the service they provided. From the moment they arrived at the job site, Oswaldo displayed exceptional professionalism and expertise. He quickly assessed the areas that needed attention and promptly updated the repair plan to ensure it met the specific requirements of the situation. Despite facing challenging weather conditions—snow and ice melt, followed by heavy rain, and an unexpected flow of water under the house—Oswaldo and his team showcased remarkable perseverance. Their dedication to completing the job, no matter the obstacles, was commendable. Additionally, I appreciated Oswaldo's commitment to communication. He kept me thoroughly updated on the project's progress and any necessary changes, which provided me peace of mind throughout the process. Overall, I highly recommend Oswaldo and his team for any foundation repair needs. Their experti"

"All Aspects Waterproofing installed a French Drain and new sump pump in my basement. The project also required adding a curb to the foundation. From the estimate to project close out, all of the employees were great to deal with - very responsive to emails and calls with questions and pro-actively called me to keep me up to date throughout the process of getting the permits and inspections, coordinating with my plumber who took out and installed new hot water heater, and coordinating with my own schedule. All of the workers who came and did the hard work were great - they worked very clean and went above and beyond helping remove items I needed to have out of the way for their work and left my basement and yard (where they needed to do some of the prep like making concrete) spotless. They were great - responsible, knowledgeable, honest, friendly, reassuring - and I would totally use them again. Also, great value."

"Was polite and professional but didn't have the tools needed to properly unclog my underground gutter drain which was clogged with roots. Tried a mechanical auger that he had but that was all he could do and only pulled thin roots which helped but didn't completely unclog the drain."

"Excellent service. The technician (I am blanking on his name) was very professional. He looked at the issue (clogged drain), gave me a couple of options, we chose one, he proceeded with unclogging the drain and voila, no more issue. Thank you!"

"Came promptly the first day I contacted them. Job was to clear a clogged laundry drain buried in slab floor between laundry room and kitchen two rooms away. The construction is old, not up to current code. The job required dismantling fixtures at both ends of line. They worked diligently, explained what they were doing (and current building practice), reassembled everything, and cleaned up thoroughly. They solved the problem! I would hire again, and I recommend."

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.
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.
