Licensed #897075 · Categories B, C61, & D30

A foundation problem on a commercial property is stressful — your building, your tenants, and your budget are all on the line, and it’s hard to know who to trust. Jim Lopez started Pinnacle Home Services to be that company. In 13+ years he’s built it on one principle: tell property owners the truth, and stand behind every repair — because he saw too many buildings sold the biggest, most expensive fix when a smaller, smarter solution would have protected them just as well.

On commercial projects Jim stays personally involved — reviewing the plan and partnering with licensed structural engineers on complex work — so you get an honest assessment, a clear written scope, and pricing you can take to ownership. His name is on the license (#897075), and his reputation rides on the outcome — which is why Northern California property owners, managers, and realtors keep Pinnacle on speed dial.

"On a commercial property, you're accountable to owners and tenants — and so am I. My job is to protect your building and make the whole process clear, documented, and done right the first time."

Rick and Andrew, were great during while looking at my foundation issues. They recommended a solution that fits my 1950's house, rather than suggesting a complete overhaul. I haven't made my final decision yet, but I would feel comfortable going with Pinnacle based on my experience with Rick and Andrew.

Thank you Mr. Lopez! Very professional. Even the lady who answered the phone was very polite and I was very impressed as a construction business owner my self. His expertise sounds like it goes back decades. He seems like a legend in his industry.

I had some cracks in my foundation that I was concerned about. They came out and took measurements. I 100% recommend this company because they were actually honest. (Another company skewed measurements and pressured me to commit, they called and emailed a half dozen times within a day of coming out). If you need or don’t need repairs, they’ll kick it to you straight with no bs. Highly recommend.

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 a new Girder system and support posts mounted on 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 support post with seismic hardware; & 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 was 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 knew that having the foundation stabilized was going to be vital to 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 ~45-60 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!

A+ service plus 5 star foundation knowledge! Jim and his team understand foundation issues better than any company I've worked with and how to fix problems the first time without unnecessary repairs. Our foundation issue was repaired on time within 2 weeks of his first visit exactly as quoted with no issues. They use state of the art leveling technology to better understand and repair foundations. I highly recommend them!

Omg. We’ve spent the last five years trying to resolve high humidity levels in our crawlspace. We bought the house in 2017 and a year later I became very sick and a year later we identified toxic mold as the source of my illness. We spent thousands of dollars in remediation and thousands more trying to fix humidity issue. Humidity levels were consistently in 80% to 90% range. There was no obvious source of moisture intrusion. We had multiple crawlspace experts evaluate the space and none of their recommended fixes solved the problem. We were hours short of signing a full encapsulation contract and decided to have Pinnacle come give us their opinion. They identified the problem immediately! The previous owner’s home improvements had eliminated four crawlspace vents. We hired Pinnacle to add four vents and the humidity problem was resolved immediately!! Everyone we worked with at the company was friendly, professional, timely, and the cost was a fraction of full encapsulation!! So happy and highly recommend and trust them!! Only wish we hired them five years ago!!

Excellent experience with Jim at Pinnacle Home Services. A client of ours had some questions regarding foundation findings on a home inspection. Jim was super quick to respond and share his expertise over the phone and email. He also offered a comprehensive foundation assessment for a very reasonable fee. Thanks again, Jim!

Wow. What a great experience. We had called two other foundation companies and we felt really good about Pinnacle. Not only did they level our house the cracks in the walls disappeared. We are with the work they did. Very Honest people there.

Commercial FAQ

Common Commercial Foundation Questions

Straight answers to what Sacramento property managers and owners ask most.

What are the signs of a commercial foundation problem?

Common signs include cracks in exterior walls or brick (especially stair-step cracks), cracked slab or warehouse floors, sloping or uneven floors, doors and windows that stick or fall out of square, and cracks in drywall or stucco. The earlier a problem is caught, the easier and less costly it is to fix — so an inspection is the smart first step.

What causes commercial foundation problems?

The most common causes are expansive or poor soil conditions, poor drainage and seasonal moisture changes, plumbing leaks, heavy building loads, and original construction issues. Sacramento-area soils and moisture swings make these especially common here.

How is commercial foundation repair different from residential?

Commercial projects involve larger footprints, heavier structural loads, and stricter code requirements — so they often call for engineered plans, structural loading analysis, and heavier-duty solutions like steel piers, underpinning, and polyurethane injection. We work with licensed structural engineers on complex projects.

Will the repairs disrupt my business or tenants?

In most cases you can keep operating. We schedule around your business hours — including off-hours or phased work — to minimize disruption to tenants and daily operations. The exact plan depends on the scope, which we document up front.

How long does commercial foundation repair take?

Most commercial repairs take from a few days to a few weeks depending on the size and scope of the work. Your free assessment gives you a clear timeline for your specific property.

Are you licensed and insured? Can you provide a certificate of insurance (COI)?

Yes. Pinnacle is licensed (#897075) in categories B, C61, and D30 and fully insured, and we can provide a certificate of insurance for your property or ownership requirements before work begins.

Do you provide written proposals and work with engineers?

Yes. Every assessment includes photos, documented findings, and a clear written scope and price you can budget and present to ownership or your board. For complex projects we collaborate with licensed structural engineers for permit-ready calculations.

Do you offer free inspections?

Yes — we offer a free on-site inspection for commercial property owners, with photos and a documented scope. Note: foundation inspection reports for real-estate transactions (buying or selling) are a separate paid service — just ask and we’ll explain the options.
