What customers say

Customers praise professional crews, efficient work and clear explanations. One customer says the team came quickly to quote and returned about a week later to complete the repairs. A customer who reported two sinkholes after the dirt settled says their air-conditioning unit was tilting; follow-up appointments were repeatedly rescheduled, no callback came, and they hired someone else to fill the dirt.

Groundworks came out quickly for a quote and came back to complete the repairs about a week later. Anthony and Brian worked efficiently to get the job done quickly! We appreciate the professionalism and fast turnaround.

I cannot say enough good things about this company and their staff. Our point-of-contact was Steve. He was an absolute top-notch professional. He exhibited top quality customer service and communication. He could explain the more technical parts in a way a layperson could easily understand. He was courteous, easy-going, and very conscientious inside and with our home. If you think you might have structure issues, I highly recommend consulting with Grooundworks, and ask for Steve!

The team from Groundworks was awesome! Mark Papillion, Luis Gutierrez and Ken were prompt, knowledgeable, friendly, clean & experts at their craft. They were attentive, unobtrusive and quick. I thought this job would take longer but they really finished quickly. They were very good at explaining how to maintain the environment and purifier. Thanx team!

We recently had Groundworks lift the back of our home and we couldn’t be happier with the results. The crew was professional, hard-working, and extremely knowledgeable. They explained every step of the process, arrived on time each day, and kept the area clean and organized. The job was done efficiently, and the difference is incredible.We are so impressed with their workmanship and attention to detail truly excellent workers. Highly recommend recommend Groundworks for anyone needing foundation or lifting work done.
