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.

    Very happy to have worked with this company. Honest. Great in explaining what they are doing. Was willing to help me out with the deck that was in the way... made life so much easier. Responsive to calls, texts, and emails. I'm now trying to sell the house, and they are helping with the warranty transfer and re-inspecting the house for the potential new buyer. Shout out to Jesse the superman!

    The crew who came to do the foundation repair were very good , workers and respectful ,I was very pleased with the tremendous hard work they did to get my house leveled the right way and put everything back in place . The supervisors called me frequently also to make sure that i was satisfied with the work in progress Hats off to the whole crew from Pinnacle for a job well done ,
    Sorry this has taken so long: But my wife and I had a Great Experience dealing with Brian Phillips, Consultant for Pinnacle Foundation Repair. He did a professional job of investigating the foundation problems of our house and asked all the important questions about the history of the house and any and all work that had been done to this house. He knew by looking at the surrounding area of the house and the visual topography how the water intrusion under the house had effected the foundation. But more importantly, he had a clean design of how to fix the problems of this foundation. We are now planning to get Pinnacle activated to start as soon as they can with these fixes. Once again, thanks Brian for your time and effort!! G Cantu Jr.

    Jason from Pinnacle Foundation Repair came out to evaluate our house for drainage and water flooding issues in the backyard. I greatly appreciated his honest communication and thorough evaluation. Before calling this company I looked them up on the BBB website where they had high ratings. I trust their professional opinion and will be working with my HOA to address drainage issues within our community.
    Brian from Pinnacle Foundation Repair was exceptional! Prepared, kind and focused on getting me the most for my money! Thank you Brian!

    I just want to say thank you so much to Heather! As a first-time homebuyer, I was feeling really nervous and overwhelmed after some potential foundation concerns came up during my inspection. I was referred to Heather by a mutual friend, and she was so kind, knowledgeable, and reassuring from the beginning. She came out to look at the property, answered all of my questions, and took the time to explain everything to me. She even gave me helpful advice about home maintenance and other areas around the house. I truly appreciate her honesty and willingness to help. I’m so thankful I was referred to her and would highly recommend Heather to anyone with foundation concerns!

    This review is based only on the bidding process. I am getting 3 bids but will likely go with Pinnacle. They were the most responsive to my emails, questions, and concerns. Brian quoted a price that is very fair and he took the time to come in person to educate me, show me visual examples, show me their various options, and provided funding options. I called based on their BBB ratings and number of years in business. Brian listens and responds in a manner that is a problem solver not a SALESMAN.

    Jason came out to do an evaluation and was hands down one of the best people we’ve dealt with throughout our home renovation process. He was real, upfront, honest, and incredibly knowledgeable. From the moment he arrived, it never felt like a sales pitch. Unlike a lot of foundation companies that make you feel pressured or just try to scare you into unnecessary repairs, Jason simply told it like it is. He took the time to explain everything clearly, answered all of our questions, and gave us an honest assessment without trying to sell us something we didn’t need. He was friendly, personable, professional, and genuinely cared about helping us understand what was going on with our home. It was so refreshing to meet someone who was straightforward, trustworthy, and easy to talk to. If you’re looking for honest answers instead of a sales pitch, this is the company to call. Highly recommend!

    John Campbell was very helpful is explaining in detail of what needed to happen for our foundation. Even telling us things we don't have to have done, which for a company to do, is incredible. He was very knowledgeable and got us set up with a gameplan after feeling a little lost. Definitely recommend!

    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.
