Groundworks Provides Professional Foundation and Crawl Space Repair
Longmont 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 Longmont is mostly made of clay. This is one of the most problematic soil types for foundation construction. Clay soils absorb and hold water, causing the ground to expand and push your foundation out of line. This added water content also 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 Colorado, you can trust we aren’t going anywhere and will be there if you need us. Let one of our trained inspectors walk you through our custom solutions to solve your home’s unique problems.

Everyone we interacted with here provided exceptional service. Aaron was very thorough in his explanations and measuring. He explained the suggested plans to us and answered all of our questions. Prince and Cleveland were very communicative on when they would be arriving and completed the work very quickly. The porch is in much better shape, and they managed to close gaps that were about 1 in down to less than a centimeter with minimal damage to the existing structure. I will definitely be using them for any future structural work that needs to be done.

We had Ground Works come out to our home to raise some slabs in our driveway and back patio. Manuel Belio and Jose Ortiz arrived as scheduled, looked over the job and went to work. I was a little concerned because they had to straighten out 3 slabs in the driveway that were raised 3 years ago by another company but settled more than 1 1/2 inches. Manuel said there wouldn't be any problem , they run into that all the time. I am 80 years old and have problems with trip hazards, when they were finished the job was like walking on a single slab of concrete. If you use Ground works for your concrete leveling you should see if you can request Manuel and Jose for your job.

Earlier today, Mike Gold from Groundworks inspected our sump pump and seal lining that was installed last year. Despite a long drive to the mountains from Denver, Mike was right on time. In fact, Mike thoughtfully called beforehand to see if ok to come about an hour earlier, and texted me when he was 5 mins away. Mike’s demeanor was both professional and pleasant. Mike did a full inspection and test of the system, as well as re-attached part of our crawlspace seal lining to our wall, in 30 minutes. Mike showed me photos, and even looked for potential mouse droppings at my request. For our future inspections, I’m going to ask for Mike. Groundworks is fortunate to have him on their team. Thanks again Mike.

Francisco, Rene, and Salvador were so nice to me and treated me with respect. I am very happy with the work they did, it barely looks like part of the yard was dug up to lift my house.

Eric and Ryan did a fine job and worked a strong, hard day to get my enormous driveway leveled and lifted to the best they can given the circumstances and conditions of my concrete. My house is nearly 60 years old and my concrete definitely was not in the best condition or ideal dimensions to make a perfect repair. It wasn’t horrible, but I didn’t want to wait until someone busted their face on my driveway to make it safe to walk on. Even with the portions of the driveway that resisted getting perfectly level, I’m happy to avoid needing to replace my concrete and now that everything has been stabilized with foam and no longer need to worry about the driveway for years to come. I may consider grinding down more high spots on my own if it’s an issue clearing snow this winter with my snow blower. If I tried to do this job myself I wouldn’t have done a great job because the shear volume of foam that was needed to do the job was enormous. Plus, any foam I could have used would have been inadequate for the job it was designed to perform and I don’t think I could have injected foam fast enough to make much of a difference. Granted, I could have searched and found something to use, but man given my tight schedule with a toddler and work, it’s nice to get to done by someone who has all the right tools and skills to ensure that nothing is overdone. I didn’t want to pay for equipment that I was needed for this specialized job. (Although I could have looked for rental equipment….) Anyways! For a two man crew tackling a 1000+ sqft driveway racing against the rain, wow what a performance! Eric and Ryan were very responsive to any questions I had during the job, which was very nice. I wish they spent more time blowing off the dust and debris off the driveway and in my garage, but it started raining shortly after they left so I guess there isn’t much that could have been done. I’d give five stars for the work Eric and Ryan did, but I’m giving four stars because Groundworks backed out of repairing the public sidewalk that we originally agreed upon due to “Liability Issues” which was the original reason I called them in the first place because in my city I am responsible for repairing/maintaining my public sidewalks. Although Jacob, the representative to helped develop the service agreement and initially inspected the concrete, pushed back to keep it in the scope of work, Groundworks didn’t want to risk damaging the road repairing my sidewalk getting the city involved. They do advertise sidewalk repair, which is why I’m bringing it up here in a review… if you’re trying to get your sidewalk repaired you may need to just get it fully replaced or get trip hazards ground down (I got my sidewalk ground down from someone else) lifting/stabilizing public sidewalks you’re responsible for maintaining may be out of the question- at least for Groundworks. I recommend Groundworks and likely will call them again for future work on other projects around the house. I just wish they would have helped me with my sidewalk because it was a scramble to find someone to help grind down the sidewalk in the timeframe I was looking at getting the work done. Thanks Jacob, Eric, and Ryan for helping with my driveway!

My inspector, Curtis, was knowledgeable and explained the issue I was having in a way that I could understand. Luis, Ramon, and KeVaughn did an amazing job with installing my basement solution. The entire encounter with Groundworks was solid. They were able to get an inspector and team out quickly.

This team is fantastic! Mark first came to my home, assessed my needs and proposed a solution. During the preparation stage, Mark and other members of the team stayed in touch. On remediation day 1, Silvino contacted me regarding his arrival time. The excellent communication continued over the 2 days they were in my home. His team was polite, professional and extremely clean. They minimized the intrusion in my life, which isn't easy when you have jackhammers in your basement. Upon their exit, Silvino promised to send photos of the entire process. I highly recommend Groundworks!

Had an emergency water pipe leak with water running into the basement where Groundworks had already installed a sump pump and drainage system. The pump clogged up with mud and wouldn’t work. Josh Moreno responded and worked so hard getting the system apart and cleaned out. Unfortunately he couldn’t finish until we got someone out to dig up the front yard and replace main water line. Josh was here first thing Monday morning and finished cleaning the system out, tested everything, and got everything working again. We are so thankful he responded to our home and took care of it. Thanks Josh!

We had our driveway and front porch steps stabilized. Alexander Fancher is great to work with. He explained everything thoroughly and was always on time and did what he said he was going to do. These days that is really appreciated. Alexander checked the whole driveway and not just the part that had sunk.

We’ve had some basement flooding issues over the years. In 2023 we hired Groundworks to assist with the mitigation. We just had our 1 year preventive maintenance. Josh Moreno was our inspector. He was polite, thorough, and knowledgeable about our systems in place. He tested everything and walked us through the process as he did it. We’re pleased with Groundworks and Josh!
