    Injecting expanding foam under the sunken slab.
    David K.

    Groundworks responded immediately to my need to lift a sunken 20x6 foot section of a concrete slab that had cracked and drifted 1 inch laterally and sunk 2 inches along the long edge. Alan Dawber measured the amount of sink with specialized equipment and provided a reasonable estimate to inject expanding foam to lift and stabilize the problem areas. Crew of Oscar Gonzalez and Riccardo Vargas drilled about 20 injection holes and in 2 hours leveled and stabilized the slab. They were efficient, clean and expertly leveled uneven sections. Much cheaper than demo and pouring new concrete

    Professional team, hard working, got the job done in record time. Rob, in sales did a great job with the inspections and letting me know what my options were. Left the work area tidy and did a phenomenal job, shout out to Brandon, Edgar & Oscar.

    Sunshine Foundation Repairs - Foundation Replacement

Some contractors only walked around the exterior of my home, while others took a quick look underneath. Jon, the field representative from Sunshine Foundation Repairs was different from the moment he arrived. He was on time, friendly, professional, and immediately went into the crawl space to perform a thorough inspection. I was impressed that I received a detailed proposal the very same day. The biggest reason I chose Sunshine Builders was the quality of Jon's inspection. He was the only contractor who identified sagging floor joists in my living room, which likely explained the squeaking floors I had been hearing. He documented the issue with photos and recommended the appropriate repairs, giving me confidence that he was looking out for the long-term integrity of my home--not just trying to sell a standard retrofit. Throughout the entire process, Jon kept me informed every step of the way, from permitting and plan check to scheduling the installation. Communication was excellent, and I always knew what to expect. On inspection day, everything went smoothly. The contractor arrived prepared with all the required paperwork, met with the City inspector, and ensured the inspection was completed without any issues. Jon made an outstanding first impression and represented Sunshine Foundation Repairs exceptionally well. His thorough inspection, attention to detail, clear communication, and guidance throughout the entire process are the reasons why I chose Sunshine Foundation Repairs I would highly recommend them. The proposal bid was right where my budget was.

The crew arrived early in the morning and got started right away. Everyone was in sync and worked efficiently, completing the job faster than I expected. They also left the crawl space clean and removed all debris and trash. I'm very happy with their service and would definitely recommend them.

    I feel compelled to share our latest alarming experience with Anchorstrong. An employee, Joe Essy,…read morethreatened us via email, stating that he might file false reports against us unless we removed our honest Yelp reviews. He also suggested that he might leave negative reviews for a kind handyman we've worked with and file false reports against him, despite never having used his services. We also asked Joe to provide the permit he claimed to obtain for our project, as required by our contract. Several weeks have passed with no response, leading us to believe he never secured it. Rosie (Office Manager) and Steve (owner) were copied on our email, and we forwarded Joe's threatening email to them as well, but they have not responded. I also have serious concerns that Joe may have created multiple accounts to post fake reviews, including negative ones for others that reflect the threats he made in his email to us, as well as positive ones for his own business and employer. Yelp has removed several reviews based on these issues, and I have documented evidence to support my claims. Believe it or not, Joe has done more shady things, which we've documented. To keep this more concise, I'm highlighting just these examples but there are many more. In my opinion, Joe's behavior is not only beyond unprofessional but also seems unhinged to me. Who engages in such extreme, dishonest tactics against their customers simply because they left honest feedback? Providing feedback is our right as customers and a key purpose of Yelp. Multiple individuals who interacted with Joe raised serious concerns about his questionable honesty, erratic temperament, and disrespectful behavior. The emails I shared from Costco are just a few examples of this (see photos I posted in this review). Instead of simply addressing valid feedback, Joe resorts to intimidation tactics. His actions made me feel unsafe enough to install a security camera, especially since Joe said he lost the key to our front door. It's deeply disturbing that Joe has threatened to unfairly target us and this handyman--who has nothing to do with this situation and doesn't even know Joe--in what seems to be retaliation for our honest reviews. This handyman is genuinely kind, hardworking, and excellent at his job. He does not deserve this treatment at all. Since Joe mentioned he provides handyman services himself, Joe's threats also raise serious concerns about a conflict of interest. Based on our experience, it seems Joe is willing to go to very extreme lengths, including unethical tactics, to silence honest reviews, suggesting serious issues. His intimidating behavior has been completely unjustified and, in my opinion, it's shameful. Anchorstrong has failed to meet their contractual obligations, leaving us with substantial damages and financial losses, and refusing to refund us or work with us toward a fair resolution. After we paid them over $34K, we've faced intimidation, which we have proof of, instead of accountability. As paying customers, it's disheartening to experience such unethical treatment. If you work with them, be prepared for the same treatment. Also, ensure all permits are actually secured. I didn't want to write this update because this company isn't worth anyone's time, but their intimidation has led me to warn others and I hope it helps someone make a more informed decision. We've never encountered such appalling treatment from a vendor before. To Anchorstrong: We have every right to post honest reviews. Stop trying to intimidate us. While we've accepted that you won't provide the fair refund we are owed after taking our money, we simply want to be left alone--and for others to be left alone as well. The photos of Joe's shoddy work and the damages he caused speak for themselves. We face significant expenses to fix these issues, in addition to the $34K+ we already paid you and the other losses we incurred due to your failure to meet your contractual obligations. You have not reimbursed us, and we are left to cover these costs ourselves. Why threaten us? Haven't you done enough to us? We don't want to deal with you any further. Please leave us alone.

    We live in the hills in Los Angeles County and our chimney weighing over a ton has settled a few…read moreinches over the last few years, creating leaks in our roof with rain and pulling the floor around it. We decided with Eaglelift as they have the technology and experience of doing such work. We worked with a geo-engineer who drew up plans for installing 6 helical piers to support the chimney's footing toward halting the settling once and for all. The job also included sealing in the holes dug with high-density polyurethane foam which solidifies into solid rock, holding the helical piers, the clamps into place. The most exasperating part of working with Eaglelift was the scheduling and how our start date kept getting pushed back for months. It was scheduled as a 4.5 day job, but with rain and other challenges it ended taking up 2.5 weeks. That said, having experienced the curve balls that came with the foundation work of our chimney, it is understandable how our original start date got pushed back the way it did. My biggest angst about the job of reinforcing the foundation of the chimney was having to tear up our flooring, and the potential cracks in the old brick chimney, which towers over 20 feet tall. I was fortunate though to have a great team working at my home. They took care to cover the traffic area of the flooring with heavy paper, sealed off their working area with plastic and with a zipper to enter and exit. And when it became clear they needed more flooring to cut into, they helped me move and cover up the furniture. The team was made up Ramiro (the foreman) with colleagues Nick, Edward and Jose, and I can tell you, with all my years of remodeling and construction workers, these guys were a nice bunch to have around. They were pleasant, they enjoyed their work, and worked their tails off. The most nerve wrecking part for all involved was the lifting of the chimney by just over an inch, which was successfully achieved without any damages to the chimney and its footing, not to mention the rest of the house. All in all, I'm glad we had Eaglelift and especially Ramiro and his team. Thank you guys!

I was able to discuss the scope with the project manager and the crew got started right away. The work, installation of 16 push piers and void fill took 5 days instead of the originally quoted 7-10. The crew (Brandon, Ricardo, and Ivan) were courteous, efficient, and cognizant of our needs (access across doorways, warning before noise, calls before arrival). They often stayed a bit late to make sure excavations were safe and open holes were blocked off. They subcontracted a ground penetrating radar tech to mark out utilities within the slab to avoid any mishaps when drilling for injection ports. They lifted and stabilized the slab and performed the void fill so that our floor is probably as strong as it was when it was first constructed. They were fairly good at communicating possible change orders and were patient with my 4 year old who wanted to jump in every hole. Overall they were a wonderful crew. I knew from the plans that the work would be fairly destructive to surrounding yard and interior floor. As we have a series of interior projects (flooring, kitchen remodel, etc.) slated we gave the crew a bit of free reign in their work; The slab lift opened up some old patches, the void fill popped a few portions of our laminate floor, and a door got jammed as it was originally hung when the slab was sinking. Interior projects are not within Eaglift's scope so if you do not plan on doing an interior remodel I would engage in alternate plans for void fill. However as we are basically remodeling from the bottom up, the damage, while inconvenient, is not a deal breaker. There was dust left after drilling for injection ports and some interior concrete cutting when the plastic they used to isolate the area mistakenly ripped. The did their best to clean up afterwards but we still have some areas where we are finding dust. Billing was easy and their accounting was very accommodating when we wanted to split up payments. We had some discrepancies on some change order paperwork but that was easily dealt with over email and correct balance was invoiced. As with any contractor, you are best served by being informed. Ask what the crew is planning for the day, check against your plans, and be present for any inspections, or walk throughs. Eaglelift came through efficiently once work started. They did the job well and were consummate professionals. I would definitely recommend that you include them in your quotes for slab and foundation work for either commercial or residential projects. The delay was a huge drain on our schedule which keeps them from getting 5 stars, but that was likely an uncommon occurrence. I would recommend talking to their scheduler as well as their project engineer to get a realistic start date. They will know what their field crews are up to far better than someone coming in to provide initial quotes or draw up plans.
