Groundworks Provides Professional Foundation and Crawl Space Repair
As the most populated city in Colorado, Denver homeowners deal with their share of foundation, waterproofing, and crawl space problems. If your home is experiencing foundation cracks, uneven floors, musty odors, or sunken concrete slabs, it’s likely the area’s soil and weather conditions are to blame.
Homes, both big and small, new and old, experience problems regardless of foundation type. The soil in Denver is poorly drained clay loam. This is one of the most problematic soil types for foundation construction. Clay soils absorb and hold water, causing molecules to expand. This added water content puts pressure on basement and crawl space walls, causing them to crack and bow inward. During dry periods, which are common since the area sees less than average rainfall per year, the clay loam soil shrinks, leaving voids that are unable to support a home. A sinking foundation leads to cracks and sloping floors throughout your home. Additionally, cracks provide the perfect entry point for water and cause costly damage.
Groundworks offers various waterproofing, foundation, and crawl space repair options. Our innovative, permanent solutions are backed by long-term transferable warranties for peace of mind. With more than 20 years of living and working in the Denver area, you can trust we aren’t going anywhere and will be there if you need us.

I am a property manager, and foundation issues on homes are the last thing anyone in my position wants to deal with. Fortunately I worked with Mike Kilduff to get my foundation repair taken care of. Mike was incredibly communicative and made sure to check in with me every step of the way. As the work started on my home, I was also fortunate to add Armando to my project team, as the foreman for the job. He and his crew worked hard and did a great job, they even closed some very big gaps in my brickwork, which is never something that can be guaranteed. I fully intend to use Complete Basement Systems / Groundworks for another property, and will certainly refer them to all of my contacts.

Matt Daily is a wonderful, professional, humerous, warm, easy to communicate with individual. All the positive accolades you can imagine are applicable to Matt. If the Complete Basement Systems install goes as well as Matt's presentation, we will be extremely pleased, and entering an additional review afterward. Had we not entered into a Contract for services, we would still have acquired a new life-long friend in Matt Daily.

I had 2 crawl spaces in my home encapsulated by Complete Basement Systems. Phil Haggerty was the contact person and did a very thorough inspection of both spaces and found an issue we were not expecting. He did not put any pressure on us to use his business and was very good at answering questions, addressing concerns. He returned calls the same day, if I didn't talk to him when I called. HIs crew- 2 gentlemen both named Jose, were very professional and friendly. They covered the entire path from the basement to the garage with plastic to keep everything neat. They showed up on time, worked the whole day and did a great job. I would recommend using CBS.

Edgar and Isaiah did a fantastic job leveling the columns supporting my front porch and roof. This was after a crew had tried but failed to complete the job several years earlier. They showed up exactly when they said they would, talked to me to make sure they understood exactly what I wanted done, and then got right to work. They let me know when they were ready to start raising the columns so that I could watch the progress and let them know when the porch was at the level I wanted. Even though they were short-handed, they got the job done quickly. I am very happy with the job they did.Brooks Myers

My sump pump went out and I did not realize it until late on a Friday night. 1/3 of my basement had standing water in it. I called and left a message Friday night around 10:30, knowing that they were closed on Saturday. However, first thing Saturday morning, they called me and were able to be out before 9 am. They fixed the problem and even cleaned up the standing water. They recommended ways to dry up the carpet faster. Ryan was very professional and not pushy at all. I really appreciate this business and will use them in the future for all my basement needs.

My initial installation of a basement water mitigation system was performed in October of 2021. After my basement flooded twice through two separate window wells, my neighbors recommended that I reach out to Complete Basement Systems (now Groundworks) and have them install window well drains in addition to a full basement drain system that all ran to my sump pit. My neighbors had this work done in their home 8 or 9 years ago and were thrilled.My installation was terrible. The crew was apparently very inexperienced and we had struggles communicating in English. I speak enough Spanish to get by but it would have been even more frustrating if we hadn't been able to communicate. The crew was very friendly but outside of that, everything about them was terrible. They absolutely destroyed my basement (outside of the areas they were supposed to work on). The dented my walls in the stairwell, destroyed 4 of my window screens, etc. They were like bulls in a china shop AND they didn't do their job well at all. The drains from the windows down to the drain in the floors were left unsealed, the sump cover was left unsealed, the sump was plugged into a tripped GFI outlet and the exterior drain was left pointing back into the house. It was absolutely awful. When I asked them if they tested the system, the assured me they had. I had to show them that the system (and half of my basement) didn't have power due to the tripped outlet. On top of all of that, the backup sump and battery were installed incorrectly and weren't powered at all. My $8,000 system was completely inoperable and when I showed them all of this, they said they had another job to get to and they would try to come back later in the week. Thankfully I hadn't paid and refused to pay until things were fixed, which they were later in the week.But…A year later, I'm happy with my work. After I called and spoke with a manger, they set out to make things right. I requested that a supervisor and a different crew come by and that crew (led by Travis…I think?) was phenomenal. They went through the work and fixed every single problem. Beyond that, they made things right with the damage to my home and repaired or replaced my screes for me.My most recent interaction was last week when Michael Swan, service technician, came by. He was night and day different than my first experience with their crews. He called ahead of time and walked me through everything that was noted on my account BEFORE he even came to my house. He knew of all the issues and told me everything he was going to test during his visit. He was honest, hardworking and overall just a great guy. If their crews are lead by people like Michael, my faith is restored.I'd also be remiss if I didn't give a shout out to Vicki Parrish in the main office. She is single-handedly the main reason I'm happy with my purchase. There were a couple of snafus after the majority of my issues were fixed and the operations manager ghosted me over and over again. Finally, I called the main number and talked to Vicki, who was completely blameless for any of my problems. Vicki was absolutely amazing. She took charge of my account and made things happen, even though it wasn't her job at all. Vicki was responsive, even in the midst of surgery, and made sure to keep me posted on everything that was happening.Because of Travis (I really hope I got his name right), Michael and Vicki, I am a happy customer. The work was done right the second time around, my basement has stayed completely dry and I'm happy to recommend Groundworks. I had to fight for what was right a more than I'd prefer but they honored their work and took care of me. It's been smooth sailing since last year and I wouldn't hesitate to use this company again.

I had this company come give me an estimate for raising my back porch cement slabs that had fallen away from my house for years. A very nice guy named Peyton Peeples has been my contact person. He is very knowledgeable in what needed to be done. Every time I contacted him, he was quick to respond to all my concerns and questions.About a month ago, I had the company come and do the work. They were quick and cleaned up wonderfully after done. The guy that came and did the work was named Tyler Moorehead. He walked me through everything his team was going to do and made sure I understood and agreed with him. After the work was done, he went over everything.My porch looks SO much better!! They lifted it, filled in all the cracks, and caulked the whole thing so it looks neat and tidy. I'm not embarrassed anymore to have people see my back porch. THANK YOU!!!

I called Groundworks to level my driveway and repair the back patio. They came out and gave me a fair quote told me how they would fix the areas. They were on time and completed the job in just a few hours. Happy Homeowner! they did excellent work I was very impressed. After a couple of months to me it just didn't look right. I wanted them to come out and fix it under warranty. I thought it would be a real hassle to get them to fix it to my likening. So, I called them, and they said no problem be out tomorrow to fix the issues. They arrived on time and an hour later they were finished! Happy Customer! You can't go wrong with Ground Works.

Carlos Castillo came out to do my bench marking after my job was completed. He was courteous, thorough, answered all the questions I had, and was just the nicest guy! I signed up for the 5 year bench mark to be done to make sure that the movement of my house is corrected, and would be thrilled if he was assigned to do that for me for the future. I highly recommend Carlos!
