Jesus Martinez and Miguel Murrillo were hired to make our crawl space into a useable space. They arrived on time, put down tarps to protect our floors and began work. They worked continuously and had the job completed within 15 minutes of the predicted finish time. They are professional and know their business very well. We were very happy with the work they did and would certainly request them back if we needed other work. We would consider them part of the "A" team.

Xavier and his crew were great. They were punctual and ready every day. They were professional, efficient and finished a half day early. Everything looks great and were extremely satisfied with the results. We're excited to use them on future crawlspace and foundation work for our home. Thank you - the Buchanans

Excellent service and thoroughness. They had lift our sunroom which was sinking on one side. They did a thorough investigation and feasibility study and the crew worked with us, stopping at every stage to show us the progress and make sure it was to our satisfaction

I hired these guys to level some concrete in the back and front yard. The estimate went well but fell apart after that. I gave them $1.4k upfront by the way. Installers encountered some issues, not their fault..ok. to make a long story short, every communication over the next month, I had to initiate. I finally had to ask for a refund... twice. Would not recommend it.

Although the inspector said I would need to replace everything back after the crew had left, Jesus, Miguel and Josue replaced all the large stones and left the site better than when they arrived. It looks great and they finished in record time. Professional and friendly.

I am in the middle of having a terrible experience with this company and am finding them to be unreliable, poor quality and not to stand behind their work. Following a very positive initial appointment with a Complete Basement Systems salesman, we recently hired them to install a sump pump in our basement and bury downspouts in the backyard. Because they took two days rather than the one that was scheduled to do the work I ended up making the completion payment by phone without having inspected the work. On inspection, the downspouts had been buried in a way that would require water to run uphill for the work to do any good. Much worse, the work to install the sump pump has damaged our radon mitigation system such that is causing certain areas of the house to shake constantly, loud enough that certain bedrooms cannot be slept in. This was a week ago and despite frequent calls the company has not contacted us to fix the downspouts. Unbelievably, the one contact we have had is to tell is that they refuse to fix the issues they have caused with the radon system because â itâ s not in the contractâ . Very confusing as I canâ t see anything remotely relevant in the contract. We are disputing the charges with our credit card company. Our experience is that this company is incompetent and will not stand behind their work or make things right when they screw up.. I absolutely would not trust them to work in my house again. I see others saying that this company is just interested to get their money and run which is completely consistent with my experience DO NOT USE!

Do Not Use this company. Their customer service was amazing their install techs and their service managers were terrible!! They installed multiple piers and their team did not ramp down the soil correctly. Multiple employees said they made a mistake and the GM hid behind wording the contract to not pay for the repairs. Then they online presence said they would call me back and NOTHING. They got their money and ran.

Thomas and Jose from CBS were able to lift our sunken driveway nearly six inches, and it is back in perfect alignment with our garage floor. They also sealed multiple cracks and joints in our driveway and garage. They were professional, knowledgeable, friendly, and very effective in their work. Five stars! I

Great company overall to work with. This was our second large project with them. Very professional timely and efficient. The actual work crew were great. They walked in took one look at what work was proposed and made some changes to plan to save destruction of our finished basement to a minimum but yet accomplish same goal. Structural stabilization d/t expansive soils. Roje and crew left my yard looking like they had never been here and the basement cleaner than they found it. Excellent follow up instructions and work review. So impressed with Roje, Manuel, and Christian. Even finished 1 day earlier than the contract. My only concern is the project manager the structural engineer and the foreman who actually took rein and made calls on what actual work would be never came out as a team to confirm what would need to be done so we were met with a last minute audible and big plan changes leaving us nervous and questioning the original evaluation. Recommend these 3 people go to site before work begins to make sure the plan is laid out with property owner ahead of time not after work starts. That would instill a lot more confidence In the original recommendations especially when its a large fairly, expensive project. Overall, at end of project we are very pleased with everything. Anxious to see the results over the years.

Very courteous and considerate crew. They took extra precautions to ensure cleanliness and avoid any damage to the floors while moving equipment into the basement. The quality of the work is excellent and conformed exactly to the contract. We are totally satisfied with Complete Basement Systems and highly recommend them for foundation and basement repair work.

This company was very professional. They I came when they said they would. They kept my home spotless. Put a plastic to keep dust from going to other rooms. Answered all my questions and really made me feel like we were dealing with a professional company. Michael and his crew were wonderful!. They waterproofed my basement as requested.

The Complete Basement Systems crew â â - Rogelio, Manuel, and Iranan â â - were professional, efficient, and hardworking. The service they performed was the installation of helical piers around my home to mitigate foundation settling due to the bentonite soil in the area. They made the process stress-free by immediately addressing any questions I had. They were also personable and friendly. They earned the 5-star rating!
