Foundation, Basement or Crawlspace Waterproofing / Encapsulation
We have yearly maintenance inspections done on our crawlspace encapsulation, sump pumps, dehumidifier, and on our driveway drainage grate. GROUNDWORKS has been our "one-stop go to" company for our home. Technician JR WALZ is a very articulate professional that provides courteous attention to detail service. JR explained every inspection step & maintenance procedure he was doing. He checked our cement walkway & steps for any future hazards. The GROUNDWORKS projects & service checkups have increased our home value to ourselves and frankly to any future home buyers (in my honest opinion). JR WALZ provided us with stellar written service notes to add to our house maintenance history folder. He welcomed us to call him personally for any concerns or issues we may have. We appreciated the fact that he included my wife during his service overview explanations too. Lastly, JR WALZ proactively communicated by text & phone prior to the appointment. EXCELLENT CUSTOMER SERVICE & WORK ETHICS!

Groundworks really came thru for us big time. They sent someone out to help us within a week of our calling, and not only did Tobias fix the problem, he went above and beyond the call of duty by removing a rattlesnake we had found only an hour earlier. He was a total professional and we could not possibly have received better service!!

Foundation, Basement or Crawlspace Waterproofing / Encapsulation
After heavy rain we had Groundworks mitigate water in our basement. They drafted a plan and advised on how to prevent water intruding on the east wall of our house, which consisted of a front and back bedroom. The water was currently only entering from the back bedroom, so Groundworks advised to put in an interior french drain and waterproofing. My wife and I specifically asked whether we should also mitigate the front bedroom, and they advised against because it would entail losing the bedroom closets, and the existing plan would mitigate water for the entire side of the house. We also specifically asked if we had water intrusion later in the front bedroom if it would be covered under the warranty and they confirmed that it would be covered.
Now less than 2 years later, I have water in my front basement bedroom every time it rains. I have contacted the company repeatedly, and while they initially, verbally stated that they would correct the work and make things right, they have

Great. Would use again. They’re good with their communication starting yesterday, even though their appointment was for today. Thorough conscientious and very, very respectful. If you have any questions, you can always reach out to me. I am a good reference for this work.

Concrete Injection Leveling Mudjacking
They installed two ground screw anchors to lift the sinking pillars on our back porch. They also stabilized and lifted several concrete slabs that were also sinking due to some water drainage issues. Price was acceptable and they offered some good financing options that made the project more affordable. All crews were professional and very communicative. They spent a few hours with me going over all of the options and the end result met expectations. Would recommend for anyone needing this service.

Sump Pump or Interior Foundation Drains Installation
Outstanding job! Thomas and Travis were superb!! They completed the job efficiently and quickly. I was asked several times if I had any questions about their work, as well as explaining what they were doing so I fully understood what to expect when the job was completed. They were very friendly and always courteous. True professionals!!

Had a garage driveway issue wherein several of the concrete slabs had dropped below adjacent slabs. I had the team provide an explanation of the issue, create a quote, schedule an install, and communicate arrival times as promised.The installation crew of Mike, Tyler, and Nick completed the project as requested, quickly and efficiently, as well with a great pleasant attitude. I highly recommend .

Chris and his crew were on time and ready to go to work. They were very professional and efficient. It was obvious they had done this type of work many times and knew exactly what needed to be and which step to do first, second, and third. I expected the job to take two day to complete. However thier work ethics and dedication to mission accomplishment enabled them to finish in one day. Thank you.

I hired this company to help with a water issue in my basement. they sent an inspector out to assess the situation. was told under my sidewalk was hollow and if they came drilled hoes and put foam in it would take care of the water coming into my basement. So I agreed and went ahead with the work. The next day after the work was completed there was a thunderstorm. when I got home I found not only water in my basement but mud ruined my carpet. The damage was worse than ever. there was foam product in my window well. Called the company. They sent someone out. He told me the product was not meant to prevent water problems. funny that is why I called them. Now I still have a water problem I am out $2800. my Basement carpet and walls are ruined and the Company said to be Bad. The man who came to look at the damage admitted that the sidewalk directly in front of the window well was still hollow. That is where the water came in.

Concrete Foundation Repair
The installation team of foreman Edgar, CO Shawn, and installers Ricardo and Randain were amazing! They were friendly, courteous, respectful, knowledgeable about their system, and very hardworking. They went above and beyond by completing my installation without cutting into my floors as was previously planned. They demonstrated outstanding teamwork and Edgar showed great leadership in leading by example. They are the main reason I am, and will, recommend complete basement systems. Clint Campbell that did the initial inspection was also very friendly and knowledgeable. The installation team is an asset to the company. Professional and excellent customer service. Great job, Edgar, Shawn, Ricardo, and Randain!

Concrete Foundation Repair
A very well-organized operation, from first call, to follow-up, to site inspection, proposal, and financing options. Jonathan Francone is the best. He is professional yet friendly and personable. He knew what I was dealing with, and my concerns, and gave me the proposal straight-up, and with considerations for other projects that CBS also does that would bring my systems to code, which is helpful for resale purposes, and for overall safety and health. The products used, the trade association they are part of, and the quantity of work done in the Front Range, I have complete confidence that CBS will put together the best repair system for my foundation.
