I hired Synergy for work in my home, and the experience was extremely disappointing and costly…read more The work was never completed properly and required multiple return visits because of incomplete and defective workmanship. After removing the acoustic ceiling in my living room, the crew left the ceiling exposed with visible water damage and walked away. I ultimately hired someone else to finish the work because I did not want the crew returning again. During the process, my home sustained additional damage, including a kitchen cabinet being ripped out and left in my driveway, damage to my kitchen floor, electrical wiring being cut (which required a licensed electrician), and custom drapes and blinds being torn down and balled up even though they should not have been removed. An oak cabinet was also disassembled on top of my washer, rendering it unusable. These issues were documented on site by their own representative, who expressed dissatisfaction with the quality of the work. Despite causing documented damage, the company refused to reimburse for my custom drapes, sheers, and valences for seven windows. They rejected estimates--first claiming it was fraud--without providing any alternative valuation. To this day, my window treatments have not been replaced. To make matters worse, the company attempted to bill me for a disputed balance while threatening a lien, even though the damage caused far exceeded the amount they claimed I owed. This experience resulted in significant stress, additional out-of-pocket expenses, and unresolved damage to my home. Based on my experience, I cannot recommend this company to anyone looking for professional, careful, and accountable work.

I contacted Air Quality Testers after a $20 radon testing kit from Amazon revealed that we have…read morehigh levels of radon in our basement (4.5 pCi/L). Because we were just doing this for safety and not for documentation (for example, related to a real estate transaction), they recommended that we get a $200-300 digital meter instead of springing for them to come out and test ($900). That meter showed consistently that we are at 1-2 pCi/L, which is an acceptable level. I am really impressed with this company that values integrity and honesty above profit!

We did not receive our preliminary report as expected (took a week and a follow up text, rather than the 2-3 business days communicated) and the final report was the same (took two weeks and a follow up text after the samples were taken, rather than the one week communicated). If your needs require tighter timing or more proactive communication, maybe consider alternatives but we did get the results we paid for and are happy with the price.

I hope I won't have to, but I would trust to work with Dan Eisen and his team again…read more Asbestos abatement was for popcorn ceilings throughout the house. Crew of 4 arrived on time and were efficient with set up, removal, and clean up over 2 days. The service I got was priced well compared to several others in the East Bay which was important for me. Communication with Dan was smooth and easy, and I appreciated that he walked me through the process and answered all my questions. It gave me piece of mind that things were done professionally, safely, and properly for both myself and their team's health. Note: it takes ~10 days to get the air district permit unless you pay extra for expedited service, so that the minimum wait time before abatement can start. Keep that in mind for scheduling purposes

After describing the job, I was given a verbal quote of roughly how much it would cost. Of the 4 quotes, one was several thousand higher than the other 3. Eisen's verbal quote was in the same ballpark as the others. Only downside is that they are scheduled 1.5 months out and very busy.

He was patient, friendly, and thorough during the initial walk-through inspection and testing process.

As a fellow small business owner, I cannot highly recommend Patrick and his team enough. Patrick is…read morea true Godsend and indeed an answer to prayer. We had a mold issue downstairs in a storage area in our basement. This basement area is adjacent to a renter's bedroom, so yeah, big problem! We initially tried to deal with the problem by scrubbing ourselves but my wife got sick while attempting to do so (KIDS...DON'T TRY THIS AT HOME!) Patrick to the rescue. I was able to quickly get an appointment and he was able to quickly assess the problem. His team of John and another gentleman WORKED THEIR BUTTS OFF!!!! They basically had to sand all the mold that had accumulated on the wood...I heard dual sanders going on downstairs for hours on end. THEY WORKED SOOOOOO HARD! They came by on October 1st during the heat wave when it reached 103 degrees outside. They worked from about 10 am to 4 pm to completely remediate our mold situation. When they knocked on our door at about 1 pm, they were dripping in sweat. By 430 pm or so it was done. Patrick was nice enough to leave his air scrubber for three days to completely purify the air. Patrick is an amazing businessman because he is an amazing PERSON. This guy's life is driven with PURPOSE & PASSION. Do you guys remember the Ultimate Warrior from WWE? Patrick is the ULTIMATE MOLD WARRIOR! We are thankful to God for allowing us to meet and find Patrick. His estimate was also significantly cheaper than the other 3 quotes we got and I can guarantee that the work is better just based on what I saw. The end result is our basement is free and clear of mold and I can rest easy knowing my renter's respiratory system is not compromised. THANK YOU PATRICK! I will recommend you to all my friends!

Stay away from this company…read more They secretly worked with my public adjuster behind my back and billed my insurance policy an outrageous $5,000 for an asbestos test -- all without my knowledge, authorization, or a signed contract. They even went directly to my insurance adjuster to request payment, bypassing me entirely. To make matters worse, their so-called $5,000 report is only valid for 60 days. If you don't complete the abatement work within that time, they charge you again -- even though all they do is reprint the same report with a new date. No new testing. No new work. Just another charge. When I filed a small claims case against them, they refused to accept the delivery of the court documents by not opening the door for the serving man, dodging service attempts by not answering the door. It was clear they were trying to avoid accountability. I had to find alternative ways to serve them because they simply would not cooperate. Attached is the invoice they charged against my insurance policy. I have also reported them to the California Department of Insurance and is pursuing them through small claims court. I will update this review with the outcome once the case is resolved. If you value transparency and honest business practices, please stay away from this company. Learn from my experience. If I Yelp has negative reviews ratings, I definitely will rate this company as negative! - Jason
