Showed up on time; completed project under schedule; VERY conscientious about not tracking any dirt from crawlspace onto floor; took LOTS of before and after pictures to show/explain what was done as it is very hard from to move around our crawlspace; trenched 5 downspout to keep water away from foundation; now the project has been completed I would say encapsulating a dirt crawl space is as necessary for a home maintenance as good insulation and widows and should be done as soon as possible rather than waiting until it HAS to be done; I would give this company 20 stars if I could!!!!

We hired Rob Martin CBS for a $50,000 plus foundation stability project. If your project requires engineering consultation and extensive communication between CBS management and its on-site workers, do not hire CBS. We experienced little customer service and sometimes their communication bordered on bullying. Concerns started when they recommended a modification to our engineer's original plan. Within a week of this conversation a sump pump was installed. They sent a bill for an additional $6K. We had a meeting to discuss all the accruing problems. Our main point of contention regarding the sump pump was that a change order was never presented, no pricing was reviewed and no agreement was ever obtained from us. CBS was not prepared to own this mistake. In our group meeting, Jason turned to the employee, Augustine, who installed the sump pump, looked at me and asked if I was prepared to tell Augustine that he needed to take the $6000 from his paycheck to cover the cost. Ultimately, CBS covered the cost of their mistake. This incidence was the catalyst for ongoing dysfunction. In this same meeting, negligent work was identified. * In the original foundation design, the French Drain was to be dug to 3-4 feet deep. The French Drain had already been dug and it had only been dug to 6-12 inches. *When digging the French Drain, instead of respecting our property and simply removing the patio pavers, the crew completely destroyed the patio by sawing down the middle of the patio pavers. The work continued and our property continued to be disregarded. A window was broken by the CBS concrete crew. 4 weeks later, and winter approaching, the window had not been repaired despite their awareness. When they went back to dig the French Drain, to the appropriate specification, they cut through a sprinkler line disabling the system. When they replaced the dirt, after digging the trench, they did not tamp it down correctly and that portion of the yard began to sink. The French Drain needs a pressure release cap to allow the system to function appropriately. They utilized solid caps which would have rendered the system ineffective should it ever be employed. There was a window flower box that one of the workers disengaged and just left it there. We were responsible for moving the furnace so that they could build a cement retaining wall. On the original plan, CBS was to verify the wall height with the engineer. This was verified with the engineer and the construction manager, Jose. Unfortunately, the CBS concrete guy built the wall above the verified height and also sprayed cement over all the furnace vents rendering them inoperable. The wall was too high thus making it impossible to re-install the furnace. The concrete guy failed to show twice to provide repair solutions. We told Jose we would hire our own contractor, to repair these problems and that we would bill CBS for the cost. Jose agreed. We had to hir

Lalo and his crew were excellent. They were running behind, but called to let me know what was going on. Lalo was very courteous and his crew was respectful of our home; leaving the work area cleaner than they found it. The work was high quality and very efficient (5.5 hours for 38 linear feet of drainage channels and a sump).

My project involved leveling my existing driveway slabs. The project presented several challenges for a number of reasons, however, Complete Basement Systems, after the project was completed, provided a full refund for the project. CBS stands by its work, no question. Next year, I will probably replace the driveway and plan to invite CBS to bid for the project.

I had a difficult exterior leak in stucco that was quite small. Rather than a sump pump they sealed the outside wall. But they left a gap at the top of the impermeable material that they adhered to the wall. This had to be repaired. Still not entirely convinced that it will adhere due to the rough surface of the stucco. There is only a one year warrantee on an exterior patch like this whereas an internal fix is much longer. Was expensive for the amount of time actually expended.

Jose V. and his team (Geraldo, Manuel) did a great job. I really did not believe they could dig and install a new basement sump, lay the water guard channels, with new concrete, install drains to the outside under the lawn, and correct the issues in a window well ALL IN ONE DAY, but they did. It was very hard work, including hauling old concrete up the stairs. Oh, and they also scheduled the electrician to put in a new line for the pump the same day too. They were very efficient, the job was done neatly, and even the lawn looks perfect again. Will know more after the next torrential rain, but I am confident that our basement water problem is solved. (I am a repeat customer. Had Complete Basement System do driveway leveling in a prior house, also good work.)

These guys are awesome! I had a new sump pump installed at the house, and the technician showed up 10 minutes early! That never happens! He was super nice, intelligent and explained everything. The work was done quickly and at a fair price. I highly recommend Rod M. Complete Basement Systems to any homeowner that needs their services.

Jose Amaya and his brothers did a fantastic job fixing our foundation issue. Jose kept me up-to-date on everything his team was doing, he was extremely customer focused. I loved how he took the time to explain things to me so I would better understand what was being done, why and how. The team was amazing, I would 100% recommend them to anyone. It was a win-win.

Lalo was the hardest working foreman I have ever seen. He cares deeply about the quality of not only his work, but the work of his team. I appreciated their care as they worked to stabilize our foundation. This was a VERY tough job and entailed a ton of pure physical labor. These men were diligent and did a great job! I would request this team in particular as they went above and beyond to solve our problem and then put our "war zone" back to better than when they began. Thanks again gentlemen, your hard work was VERY appreciated.

Tony and his team were great! They were very professional and had the project completed sooner than we expected. They enclosed entire crawl space with protective lining and also put in a floor drain. Looks great! We did not get any other estimates so unsure how price compares. Very happy with the company!

I had them repair a floating floor that had been sinking for about 10 years. They did an excellent job and I am very happy with the results. Upon searching for another repair which is in a different category, I spoke with their staff and was given courteous and helpful information even though they would not be the type of company for the repair I need.
