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 cracksuneven floorsmusty 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 waterproofingfoundation, 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.

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!

Our family had a great experience with Groundworks. Cody came for our initial inspection and acted as our coordinator throughout the project. He is kind, professional, and available for consultation and guidance. The construction team was efficient and friendly. This was a very stressful time for our family and I’m so glad we chose groundworks for the project – they put our minds at ease. I had full trust that they would do a good job given their lifetime guarantee, and they did not disappoint. Absolutely recommend!

I selected Groundwork’s to devise a solution for water challenges in our home’s crawl space. Their team completed the remediation solution, but I experienced an add’l water challenge. One of their Service Engineers, Joshua Miller came to inspect and diagnosed the issue. He reacted quickly and setup remediation for resolution. I so appreciated Joshua’s honesty and leadership to set a plan in motion. Thank you very much Joshua and the Groundwork’s Team!

Had an old sump pump replaced with a modern system The experience was positive from start to finish. The initial inspector was exceedingly thorough, patient, fair, and able to give detailed yet easy to understand explanations. Luis and his installation team were highly experienced, conscientious, quick, and neat. Every single person I dealt with at Groundworks was good at their job, but on top of that, kind, communicative, and willing to go the extra mile. Highly recommended.

Groundworks Field Inspector Mike Gold was excellent in communicating with us the results of his work/measurements on our property. He explained that we now have a baseline for comparison in future years re: our house's foundation settling. He also informed us about the effect of moisture content of soil below the foundation and how to mitigate the potential problem. He is indeed knowledgeable in his area of expertise and has excellent communication skills!

Having concerns about the foundation of your home can be overwhelming. I am so grateful to have found Groundworks! From the moment I started talking with them it was clear that customer service and professionalism is their top priority. Kalen the project manager arrived right on time, and was incredibly thorough in inspecting my home and spending time with me to make sure I understood his findings. Often when I’ve had basic assessments it’s with an estimator who will have no connection to the work, and I value the fact that Groundworks sends the person who would manage a possible project for the initial inspection. I highly recommend them!
