Part one of a two part foundation project Recently we had…read moreour house foundation repaired by Groundworks out of Fairfield. One bedroom had sunk by almost 5 inches as that part of the house had been built on fill. In order to restore the house to it's proper level numerous foundation jacks and floor leveling screw jacks were required. In addition some landscaping bushes and pvc sprinkler pipes had to temporarily removed. Groundworks had informed me prior to starting work what would be required to successfully complete this project and had my full approval. The house is now level, the doors no longer swing on their own and the interior cracks between the walls and ceiling joints no longer exist. Prior to the crew leaving the yard was cleaned up and the pvc pipes replaced. Best of all Groundworks will come back annually to the next 5 years and make any necessary adjustments. The Groundworks crew that made this happen was Andrew, the site supervisor, Charlie and Allen. Their performance and daily communication was superior on all levels. This is part 2. The Groundworks Poly crew of Anthony & Brian were very fast and efficient in completing their part of the foundation repair contract which was to level our family room slab floor. Fast, yes, but Anthony did take the time to not only explain what they were going to do but also walked me through the process as they were working. I have no problem in recommending them & Groundworks to other home owners who need to have their foundation repaired.

All Season was the only one that offered a straight forward solution. As there were many unknowns, they offer a "time and material" bid with a max not to exceed. They did a 5-star job with much attention to detail. Set up inside laser level to make sure I was happy with the result. I will be calling them first when I do leveling on the back half of the house. Project came in at less than 1/3 of the max estimate. Super professional.

They duscussed the issue and the possible options very clearly. They also explained me what I could expect. Joro was in charge of the job. In stead of just addressing the immediate issue alone, he also looked at things beyond the problem area to ensure that is all needed fixing. After they addressed the main levelling issue near the drive they also did the match-up work in the surrounding area. They came on time and finished the job on time. It gave lot of peace of mind. Thanks to Joro and his team for the job well done.
