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.

The pool was installed in 1999…read moreand is still looking good, but the concrete structure showed its years and had linear cracks in places and one place the concrete shifted about a quarter of inch. So I thought I would have it repaired for beautification purposes. Brian the representative that came out is a fast talker and didn't explain the process of what Groundworks would and could do to improve the cracking of the concrete floor! I certainly thought that after paying $4000.00+ dollars I would be able to see a difference in the concrete. I didn't see no difference other than some lifting on the crack by the steps of the pool. Another problem I have is their is overspray of the polymer on my privacy fence. I know it is from the polymer because it is where they sprayed by the steps and diving board. I'm certainly not happy with the outcome.The crew that came were here approximately 1 hour 33 minute. WOW 4000.00 dollars just choose wisely ask a lot of questions make sure you understand what the process is. I will not refer them Stayprayedup DP

Levi Sanchez made the process seamless in its execution and follow through. Francisco paid close attention to every detail along the way. The whole process was fascinating. Never have I have any work done on my house where the workers left the place cleaner and more picked up than it was when they arrived. And things looked pretty darn good when they got here. I told them they made the neatest mess. Even the stones along where they dug down for the project were replaced better than I had arranged them. I could go on and on ... Considering how everything went so smoothly before during and after the construction, I don't think I could beat the service and value that I received. I passed Perma Level's info on yesterday to my handyman who sent it to a client of his who may give you all a call. Thank you for a great experience overall.

I had no doubt that our home was in competent hands. The workers worked very hard for about 18 days. We had 33 push piers in total. Francisco took the time to show me how the push piers worked and shared with us all the steps. Both Levi and Francisco were patient in answering all of our questions. The team was thoughtful and showed up on time every day. They secured our home when they left for the day. Our home is noticeably level now. To add, they were priced fair. The icing on the cake is when they mailed me the certification that the construction done meets all the structural requirements for structural pier placements and copies of all the pier logs and their measurements all nicely put in a folder for our records. We are all set for the roof top deck now! Thank you Levi Sanchez and Francisco for a job well done.

What followed was nearly a year of mismanagement, broken commitments, and financial consequences I'm still dealing with. They no-showed on the agreed start date. I called them at 10am to find out why -- they told me they were stuck on another job. No warning, no proactive communication. It only got worse from there. The job stretched into months of sporadic work. Midway through, they told me they needed a subcontractor for core drilling -- something that should have been identified during scoping -- then let months pass without scheduling one. My property sat in a hazardous state the entire time: open holes covered only by wood boards, piles of excavated dirt, debris, and equipment surrounded by caution tape. My homeowner's insurance company conducted a routine inspection, found the condition of my property unacceptable, threatened to drop my policy, and ultimately imposed a $2,000 surcharge. Resolving that took significant time and effort. Faced with no resolution in sight, I was pressured into accepting a reduced scope of work -- specifically, no tiebacks. Tiebacks were explicitly included in my signed contract and shown on the job drawing. Without them, there is no guarantee my home will remain stable on the hillside. I paid $52,130 for a project that does not solve my problem. After agreeing to the reduced plan, it took more months to redraw plans and pull permits, then more weeks to schedule the final visit to seal holes and reconnect drainage. On that scheduled day, they no-showed. Again. When they arrived the next day, they left without finishing. Their excuse: my gardener had told them not to proceed. My gardener -- someone I know well and trust -- told me he said no such thing. Norcal did not just take direction from someone with no authority over my contract. They fabricated an excuse to walk off the job. This company demonstrated the same pattern of behavior from the very first day to the very last: no communication, no accountability, and no follow-through.

But to complicate the roof work, we have a deck on it…read more Through Yelp , I contacted several roofing companies and none of them wanted anything to do with the deck. Except one of the roofing company recommended a general contractor they had worked with to work on the deck. It all sounded good until I asked the GC for his liability and workman's insurance which was alarmingly lacking. So I came back to Yelp for help. After meeting with several general contractors , Rothman stood out as Marshall expertly identified our deck material as Ipe wood and took steps to preserve it. Rothman also is knowledgeable and is experienced with San Francisco's permitting process. Before the roof work, Rothman efficiently disassembled our deck, removed the old frame and organized the railing and decking in a way that allowed the roofing company to move quickly and complete the roofing work smoothly. Rothman came back afterward to reassemble our deck, plank by plank, carefully and meticulously. Rothman was competitively priced and carried all necessary licenses, insurance, and certifications. Well, it is not easy to find a contractor who is honest, friendly, knowledgeable, experienced, easy to work with, pays attention to details, shows up on time, cleans up well , does great work and finishes on time. The deck looks beautiful now and we couldn't be happier with Rothman's work! Thank you Marshall!!!
