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!

"Our Man in Rio".... ....er, I should say, our man "IS" Rio,…read moreas in Rio Morales, owner-operator of Montgomery Structural Lifters. The first thing you should know, is that Rio is not just some guy who only shows-up at your job site to collect the bag-fulls of money you will likely need (regardless of who you hire) if you are unfortunate enough to need structural foundation repairs; but on the other hand, Rio was there every day on our job directing/orchestrating his crew and swinging a hammer with the best of them. That said, even if you don't know didley about foundation repairs, but are freakin'-out enough to start calling foundation experts, I can tell you from my experience of having no less than 13 contractors/foundation companies coming out in the past year before hiring Montgomery, Rio was the only one who instilled in me any confidence that his job approach was the right one for resurrecting the listing /crumbling foundation of our otherwise structurally sound 1920s Land Park garage. I initially emailed Rio pix of the deteriorated slab/foundation/dramatic leaning of the garage before he came out for his extremely thorough evaluation; and yes he did charge a fee (which was applied against his bid), but I can tell you it was the best investment I could have made. I have been in this home 43 years and am pretty handy with repairs/general construction, but I do leave the complicated jobs like foundations/roofs/HVAC to the pros, and I do know enough to ask the right questions and know the right answers when I hear them. If you don't have that kind of knowledge yourself, DON'T WORRY, Rio will give you the "straight-story" and you WON'T have to worry about getting ripped-off by shoddy work or un-needed repairs to "jack-up" a repair bill. Upon accepting the bid, Rio arranged for his structural engineer to draw-up the plans and took care of all the permitting, which went seamless, and on one occasion during the project while the city inspector was meeting with Rio on the job site, they were both on the phone with the engineer to discuss some of the foundation plans; which obviously made the "passing" inspections proceed without delays. Our job involved actually lifting the entire garage on steel beams and demo-ing the shot slab & foundation/re-racking the entire building with "come-alongs"/new internal bracing/seismic bolt & plates for the upgraded footers/headers, all which was brought up to current city code. Rio initially gave me two bids for my choosing: one to generally fix the foundation issues by repair or the second option, which I chose, to completely renovate the garage, and I couldn't be happier with Rio's attention to detail. He estimated 6 weeks from start to finish and Office Manage Dana always kept me advised of scheduling to keep Rio and crew from being in 14 places as one time! The crews always let me know beforehand what was scheduled for the day and ALWAYS showed-up on time and were a quite pleasant competent crew (Thank you to Travis, Rick, Jessie & Jesus for the great work!) OK I could go on and on, but I will say I am pretty picky who works on our house and Rio is as honest and competent as you will find, right alongside other top-notch contractors I have used ie "Fargo Construction" (now retired Land Park remodeler); "Sierra Pacific" for HVAC; and "Cal Vintage Roofing". To sum it up, we were extremely grateful that Montgomery took on our project and couldn't be happier. Thankyou Rio, Dana and the rest of the crew !!

I read the yelp reviews for Montgomery Structural Lifters. they had great reviews so I called the company to schedule a home inspection and bid.

I called the office and they kept saying he would contact me. i also emailed him again. He never responded. if he was to busy to do the job, he should have let me know that right away instead of wasting my time. I think his lack of follow thru was very unprofessional.

We removed a wall in our two story house a couple of years back and started to notice uneven floors…read morethroughout our house. I was worried that the beam supporting the roof was not adequate and that was leading to foundation issues. Most online advice suggested to hire a structural engineer to inspect the foundation, as contractors may blow minor issues out of proportion an suggest unnecessary repairs. The structural engineers quoted me $500 for an inspection and they wanted pictures from a foundation repair contractor anyways, since they wouldn't go into crawl spaces. I was losing sleep thinking about my uneven floors, so I decided to reach out to NorCal Ram Jack for a free estimate. What was there to lose? After filling out their online request form they reached out within a couple of hours and scheduled an appointment the following week with Adam, their Foundation Specialist. Adam showed up early and I was easily able to communicate my concerns to him. He measured the elevation differential throughout my house, asked about details of the removed wall and installed beam, and answered all my concerns. He walked us through his thought process and what signs of concerns we should look for that would warrant a foundation repair. We are lucky that our house currently doesn't have issues of concern, but I wouldn't hesitate to contact Ram Jack again with the peace of mind they gave us.

They peeled the carpet back,drilled the holes and re-installed the carpets to the best of their ability (which actually isn't bad at all). Fence+gate have been fixed as well. They aren't fence guys or carpet guys so leaving a review about those not done to the quality of someone who does it professionally isn't necessary, although they did do a good job with both. We appreciate the 2nd visit, no one had contacted me to change my 1star review, this is of my own doing a week later. No refund,no pay out, no negotiating, we didn't sign anything stating the review would come down after work was done. We appreciate all your guys hard work and cheerful attitude. Hope your guys liked the cookies! Thank you !

The communication is absolutely horrible, if you get any at all. With repeated attempts to follow up on my project, I kept getting the same answer that they were waiting on permitting, but on two separate occasions, over two separate issues, with two separate time spans, that was incorrect and the delay was a failure to complete the correct paperwork to even submit to the city. This caused months of delays that were unnecessary. They did damage to my electrical, but only would accept responsibility when I pushed back. The work took weeks longer than originally anticipated. All of these things I can understand, but again the terrible communication made the situation so much worse than it needed to be. The technicians who performed the work were very nice and worked their butts off. They walked onto my project totally unprepared for the work involved, even though two representatives were under my house on two separate occasions and could have assessed the work needed. I could keep going, but no one reads long reviews and I am hoping to save someone the headache I went through.
