Schedule Your Free Evaluation

Radically fair quotes: We never charge for work that doesn't need to be done. Period. End of story.

Our comprehensive free foundation evaluations give you peace of mind knowing your structure is sitting on a firm foundation. If we do find any issues, you can trust we will only suggest repairs your foundation actually needs.

    Deep in the heart of South Texas, San Marcos stands proudly as the seventh-most populous city in the United States, with a rich and diverse cultural heritage. Offering iconic attractions like the River Walk and historic Alamo, which traces its roots to a Spanish mission established in 1718, San Marcos warmly invites visitors to experience a seamless mix of history and contemporary charm. However, beneath this vibrant city lies a geological challenge – the thick clay soil. Inherent to the Blackland Prairie region of Texas, clay possesses a high shrink-swell potential, signifying a risk of foundation problems.

    At Pinnacle Foundation Repair, we understand the unique challenges posed by the San Marcos soil and climate, and our specialized team is well-equipped to address them – providing tailored solutions to tackle issues such as soil settlement, slab cracks, and foundation shifts. From free evaluations to comprehensive foundation repair services, we’re committed to ensuring the structural integrity of homes and businesses in both San Marcos and its neighboring communities.

    Free evaluations for residential and commercial properties

    Radically honest, radically reliable.

    Yep, you read that right: free evaluations. As in no cost, no hassle, no worry. The friendly experts at Pinnacle Foundation Repair are ready to inspect your foundation and check it for signs of damage using the latest techniques like ground-penetrating radar. If repairs are needed, we diagnose any issues and put together a customized plan.

    But here’s the best part: Our evaluations reveal that 1 in 3 of our clients don’t need any repair services at all. In those cases, we offer strategies to keep your structure standing firm and show you how to check for signs of potential foundation damage in the future. How’s that for radical honesty?

    Types of damage to be on alert for in San Marcos , TX

    Foundations can show signs of damage long before serious structural issues arise, but you have to know what to look for and what to do when you suspect a problem. Get ahead of the situation and prevent collateral issues by checking for these signs:

    Exterior Brick Cracks in San Antonio Texas

    Exterior Brick Cracks

    If you have a brick home and notice either horizontal or vertical cracks on the exterior of your home, this is a strong signal that your home is experiencing foundation issues and needs to be inspected by a professional.

    Cracks on Interior Walls ​in San Antonio Texas

    Cracks on Interior Walls

    Take a close look at areas like seams or breaks in the wall and other vulnerable areas inside your house. These are usually among the first places to show signs that foundation issues are a concern. Inspect drywall around doorways, windows, and thresholds for cracks and misalignment.

    Doors and Windows Sticking ​in San Antonio Texas

    Doors and Windows Sticking

    Doors and entryways will begin to sag when there’s damage to your property’s foundation. Doors often stick or potentially swing freely due to the misalignment, and windows may become hard to open and close. Check for these signs and call a professional right away.

    Cracking and Buckling Floors in San Antonio Texas

    Cracking or Buckling Floors

    Flooring issues can be a tell-tale sign that you have foundation issues. If you notice tiles are uneven or cracked, the hardwood is sagging, or if you notice cracks on your exterior slab foundation, you need to have your foundation inspected.

    Frieze Board Separation in San Antonio Texas

    Frieze Board Separation

    Frieze board separation occurs when the horizontal trim board (frieze board) visibly detaches from the exterior wall of your house. This noticeable gap is a vital indicator of potential foundation problems, signaling shifts or settlements that may jeopardize the overall structural integrity of the building.

    Pinnacle’s proven foundation repair methods

    We are experts at a wide variety of foundation repair methods. This allows us to use the best method for your specific project.

    Lifetime Warranty

    Steel Pier

    In this popular method, we interlock 12-inch steel pipes with a friction reduction plate and fill the pipes with cement to prevent the piers from failing. Steel piers can reach up to 75 feet into the ground - five times deeper than concrete cylinders. And because they can bear a higher load than any other foundation repair method, they’re a permanent solution.

    Lifetime Warranty

    Steel
    transition pier

    Struggling to choose between a steel and a concrete pier system? Get the best of both worlds. Steel transition piers mix double-walled steel and high-strength concrete to provide a strong, stable foundation at a reasonable cost. Compared to a concrete pressed piling or a drilled pier, it reaches deeper into the ground for greater stability.

    10-Year Warranty

    Drilled pier

    Drilled piers are screwed into the earth instead of pressed, which causes less strain to the building. These lightweight and durable piers are an ideal choice for smaller buildings that are unable to endure the vibrations caused by a larger hydraulic press. We reinforce these 12-to-18-inch piers with rebar and a five-sack concrete mix.

    5-Year Warranty

    Mud jacking

    Got sunken or uneven concrete slabs on your porch or home’s foundation? Our Mud Jacking process solves this by injecting a mixture of water, soil, sand, and cement beneath the surface to restore the slab’s proper elevation.

    Lalo's crew did a very efficient and well organized job on our foundation on the 22nd & 23rd this past week. They explained everything on how they were going to do it each step of the way and the clean up afterwards was excellent! They put everything back that had to be moved back in its original place. I even had some requests that Lalo didn't have to do, but he went ahead and did it for me without hesitation👍 Vito & Jesse, the managers, were great to. Just an all around great experience that I was very anxious about from the beginning. That all went away. I would recommend this company to anybody👍

    We received quotes from 4 different companies. Brian's visit with Pinnacle balanced efficiency with thoroughness. I really appreciated the crystal clear recommendation and the price was the most competitive. We're looking forward to getting soon on our foundation repair! -- I'm updating this review after the work was done. I was so impressed by Jesse Peña's crew. We have two young children and a dog, and they took a lot of care to make sure everything was left safe each night. The job was finished on time (4 days).
    Response from the owner:Wonderful to hear, Shayanne! We are ready when you are. You will receive the same level of service and professionalism as you experienced with Brian during the evaluation. Thank you for taking the time to review your experience thus far. Reviews like yours help others considering our free quote services!

    Brian Phillips did an excellent job during our initial foundation inspection. He listened to our concerns and conducted a thorough review and measurement of our foundation. He took the time to explain the current condition of our foundation and how the results of his inspection were likely causing the cracks we were seeing on the interior and exterior of our home. He explained the options available to repair our foundation and provided a detailed quote for the required work. After his visit, we are now better informed and prepared to move forward with our foundation repair. Thanks Brian!

    Brian is an excellent foundation consultant. He was running a little late, and he had the courtesy to text me. He is very knowledgeable about Pinnacle's product. I appreciate his honesty in comparing the fabrication of the steel posts with Pinnacle compared to other companies. He did his work quickly, and efficiently. He's got a great online library of Pinnacle jobs and was able to show pictures of a variety of things. He's very easy to talk to, and a good listener, inviting my questions, and answering clearly. I would recommend Pinnacle and Brian when people need foundation work done.

    Had an inspection with Ross from Pinnacle. I live in a neighborhood with well known foundation issues so I was worried I was gonna be sold something I didn’t need based on the fact that most of my neighbors have had repairs done. But Ross ran his measurements and concluded that the foundation was still in good shape. He gave me a few pointers on things to help prevent movement and things to look for before my next inspection request. Thanks Ross, I appreciate your honesty and integrity.

    We got an outstanding foundation inspection on the pier and beam home we were looking to buy. Ross was thorough, honest, and we never felt any ‘upsell’ for any thing. We got a clear quote quickly, and the peace of mind we needed to move forward. Highly recommend!

    We had a concerning interior crack that ran two stories so I called Pinnacle and they offered a free evaluation! Another company I called charged $500 just to come out. Brian was so professional yet personal. He explained the testing he did and why the results proved we didn’t have an actual foundation issue, just normal settling. Amazing customer service, and he seemed to care about my concerns as much as I did. Though we ended up not needing work done, I wanted to leave a good review. I would have gone with Brian in a heartbeat if we had needed repairs!

    The experience with Pinnacle thus far has been great. They were able to squeeze in my inspection despite having a busy schedule. Jason was knowledgeable and took the time to walk me through his findings and the available options. He listened to the circumstances around my property and helped me make a recommendation that made sense for my situation and bottom line. Based on his honesty, transparency, and competitive pricing, I have decided to move forward with the foundation repair recommendations from Pinnacle. I will update my review once the foundation repairs are complete.
    Response from the owner:Shelby, what a wonderful testament to one of our core values...Radical Honesty. We are so pleased that level of experience and dedication to transparency were evident in the evaluation!.
    I was very pleased with the transparency, honesty and integrity of everyone associated with this company. It began with Ross Adam's and ended with Jesse Pena. Jesse's crew was outstanding. Ontime, worked hard and cleaned up everyday. This was a scary process for me but the way these people handled things were outstanding. I got more than one estimate and went with Pinnacle because I felt comfortable and confident with the way my issue was handled.

    How I really wish I had called Pinnacle to begin with! It would have spared me so many headaches and days worrying! They are next level professional. (I needed to find a company to work on the exterior skirting of my mom’s pier and beam house, after new piers had already been installed by another company.) It was so nice to get a really knowledgeable and HONEST assessment from Ross!! Although the service I needed was not one they offer, I absolutely know which company I will call when I get ready to do the slab foundation repair on my own home in the fall!! Thanks again Ross!!

    FAQs about Foundation Repair in San Marcos , TX

    San Marcos soil is mainly clay, known for soaking up water like a sponge. When it rains hard, it swells, and when it dries, it shrinks. This can spell trouble for foundations, as uneven water accumulation may occur around the base, exerting pressure that can push certain areas of the foundation upwards and lead to damage.

    In most cases, the repairs will not require you to be out of the home during the process, but there are some scenarios where some rooms would have to be cleared out to cut through the slab to install piers. However, Pinnacle offers tunneling services as an option to avoid this disruption.

    The cost for foundation repairs will vary depending on the issue, but an average quality repair made by a reputable company is going to average just over $11,000 based on the thousands of repairs we have made over the past 12 months. This average cost also includes having a reputable 3rd party engineer inspecting our work, a city permit, and also a hydrostatic plumbing test by a 3rd party plumber.

    Our steel pier system is the best method used in most structures in San Marcos and surrounding areas. Not only does it penetrate even the most dense clay in Texas, providing the most permanent solution, it’s also stronger than similar steel options on the market that many national foundation repair companies offer at a higher price.

    As long as the structure is lifted correctly by a properly trained technician following the proper IRC guidelines, repairing an affected area will not cause other areas of the foundation to settle. There are some foundation repair companies that outsource their repairs to inexperienced subcontractors that have created this stigma, but we do not operate this way at Pinnacle Foundation Repair.

    It’s best to take action as soon as you see signs of failure, no matter what time of year it is. With our extreme Texas weather conditions and problematic soils in San Marcos, it’s not advised to wait to repair your foundation. As time passes, the foundation failure can worsen and have a negative impact on a greater portion of the foundation, resulting in a larger scope of repair work. While cracks in the flooring and sheetrock are obvious signs of failure, watch for less obvious signs, like doors swinging on their own, trim separation, and sloping in the floors.
