    Under house pier/post & girder repair and strengthening for foundation stabilization on a 100-year-old farmhouse
    Dar R.

    I contacted Jim Lopez of Pinnacle Home Services after receiving a home inspection report that the little 100-year old 2 bed/1 bath farmhouse I was buying had foundation & related issues. He was very prompt in responding and following up with an appointment for a quote. (We liked them so much, they also handled our subterranean termite mitigation.) He came to see my Colusa home pretty fast (within a week or so). He was very kind and personable and offered a quick turn around on a comprehensive quote for services complete with options for installment payments upon major milestones in the project which would take ~45-60 days, as permitting was required and we would be at the mercy of the City of Colusa (who actually moved things along nicely). There were many issues with the foundation & surrounding area, including: 1) previous excessive moisture conditions in the substructure with water entering from the outside; 2) hair line cracks in interior wall plaster; 3) sloping floors throughout the house; 4) displaced girder system & pier/post support structure systems (caused by long-term settling, excessive water intrusion into subarea, under-sized footers supporting the pier/post, and lack of seismic hardware [plus the main girders were also undersized]); 5) exterior stem & basement stem walls in substandard condition with settling and deterioration to the stem walls; 6) cracking/deterioration to the concrete stem walls & basement walls; and 7) foundation spalling in several areas. Jim put together an agreement to: 1) install three (3) 4" x 6" x 20' and two (2) 4" x 6" x 6' Girder systems and support posts mounted on 12" x 12" x 12" footers in between the existing stem wall foundation and girder systems to relieve pressure from the perimeter stem wall and failing girder systems; 2) install a support post with seismic hardware; and 3) install Simson Crack-Pac® to stem wall cracks to basement walls. (All while working around existing [or moving or rerouting] plumbing and HVAC ducting.) The price quote seemed fair so we contracted with Jim, who started the project within a couple of weeks of executing the agreement. For us, it was a significant investment, but we knew that having the foundation stabilized was going to be vital to the long-term value (and our peace of mind). The project went pretty perfectly. Jim was so good at assessing the details of the work, there were no major changes or deviations from the plan. We started early to mid-February and the project, including follow up inspections, concluded the first week of April - so somewhere between 45 and 60 days all said and done. Communication was excellent and they were very reliable and timely. The work was nicely executed and we never worried that the house was going to fall in on itself (particularly during earthquakes in neighboring areas). Fast forward a year and we decided to sell the home and a foundational pier/post concern came up on the buyer's inspection report. I called Jim to ask if he would come out and take a look at their concern. Not only did Jim remember me and treat me with unbelievable kindness, he expedited the no-cost follow-up / fix and ensured the house sale didn't get held up or renegotiated. I cannot recommend Jim Lopez & Pinnacle Home Services enough! They are wonderful humans with high integrity - and offer such an incredible, unique service for homeowners. In fact, my realtor called me for a referral for another home in Colusa recently and I was so pleased to refer them. This is a 5-star company ! Call them for a quote - you will definitely be glad you did!

    This is a true account of my experience in dealing with Pinnacle Home Services and Jim Lopez. Jim Lopez is now resorting to more lies in order to prevent me from telling the truth in the form of a review about this experience with his company, which I am entitled to do as a consumer. He falsified findings from his inspection in order to sell me a service I did not need. Misrepresented the result claims from said services. Damaged my home, created thousands of dollars in lost income, breached his contract, then after all that placed a lien on my home. Unfortunately I was not made aware of his contractors license until after the fact so I was unable to properly conduct due diligence on him beforehand. Turns out he has been involved in two lawsuits, both involving fraud/misrepresentation (Case No. 2010-81, Case No. 2017-38) and 12 violations with the California State Licensing Board which I am sure that number will soon more than double since I've contacted them.It's unfortunate that people conduct business in this manner, but homeowners need to protect themselves against these types of business practices. For a sinking foundation/stem wall, they said raising my sub-floors with crawl jacks would handle it. Any engineer, professional foundation company or anyone who knows about structural weight distribution would tell you that is not possible, but how was I supposed to know? I trusted this company as the "expert" and I lived out of State.My floors were level and ready to lay flooring down, before they distorted the flooring and caused it to become un-even by installing crawl jacks. Then he claimed they needed to lift them more! The room that was the worst was a huge bell curve in the middle of the room, causing about a 3" slope from the center of the room to the outer wall. How can this guy claim he wants to raise the floors more? LOL Said they would fix cracks, bait and switch to saying half of cracks from inside. I have contacted the CSLB and recommended a license suspension. Caused thousands of dollars in lost rental income and delays in the project costing more money.Jim Lopez (Pinnacle Home Service/Foundation Fixed) either knew beforehand that this cockamamie idea of his would never deliver what he promised because crawl space jacks are NOT designed to lift the foundation but to support sagging floor, or he had no business working on foundational structure work. What he sold me was a lie and I was duped.

    Three of the ten EVER-JACKs expertly installed by Charles and Alred!

    I called Jim on Wednesday to get a foundation inspection and he was able to set me up with an appointment on Friday.

    I asked my friend for a recommendation on a roofer to look at the leaks in my roof and she…read morerecommended Ray at Sealtight Roofing. She said he did a great job on roof work for her contracting company, so I called him up. I was not disappointed. An appointment was made for an inspection the very next day, The guy went into my attic with my husband, let us know it was something we could fix ourselves, told us how to do it and didn't even charge us for the time. AMAZING!!! Maybe that was the friend-of-a-friend special deal or something, but I would definitely recommend SealTight to anyone else looking for roof help. They know their stuff and want to be your hero.

    I had a hard enough time just getting someone to come give me an estimate . I appreciate getting a…read morenew roof but this place is a joke . I decided it was easiest to get financing through thier company they deal with called Service Finance Company Inc . Especially with covid starting up . I asked them if this loan worked like a normal home loan and was told yes . The interest rate looked good at 6.99% so I took it . None of my paperwork I got actually says APY on it . I made 5 payments and was noticing my principle was not dropping much nor did this company feel fit to put all the pay information on the next bill . I just found out this company is basing their fees on what a credit cards gets charged . Sealtight literally lied to me on the type of loan . The work is less than desirable . On tear off day I come home to find pieces of my siding beat to hell and pieces broken . I chewed out the foreman because he was the only one that spoke english . Then they put the roof on . They had some splash guard to put on and so instead of doing it proper they cut my siding and left a piece of metal sticking out of it . They did fix that after I chewed them out again but it looks ugly . After the roof was on they didnt pass inspection because the vents were in the wrong places . I am happy with the end results of the roof and for getting a new roof but I have to wonder how long it will last . What pisses me off the most was being lied to about the loan . I hope you got a nice pay day for the loan Sealtight because it bought you one star . I would give you zero if it was possible . I have good credit and didnt really need you to screw me over like this .
