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.


    Learn More…
    Lifetime Warranty

    Helical pier

    Helical piers are steel shafts with round helix plates that screw into the ground as deep as a steel pier, and are our go-to method where unstable soils are a concern. These piers install quickly and cause little ground disturbance and vibrations, making them ideal for tying back bowed walls or lifting fragile structures in sandy soils.


    Learn More…
    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.

    John with Pinnacle Foundation Repair came out to my parents home because they've had multiple issues in the past with other homes. It was reassuring to find out they didn't have any problems. If you're looking for a honest and thorough foundation assessment, call and ask for John!

    We had some work done by Pinnacle and we can't recommend them highly enough! The crew chief Mike was exceptional! He was very professional and answered every question and cleaned up the site beautifully! Roy and Clint were great to work with and explained everything thoroughly. Truly a class act from start to finish.

    We needed foundation work at my son’s house and received six quotes from various companies. We chose Pinnacle because of their double walled interlocking steel piers which provide strong support and because of their customer reviews. The estimator John Campbell was easy to deal with and responded to all my text messages. Jesse and the entire crew who worked at the house were polite, answered my questions and made me feel at ease over the project. We had interior piers added to the foundation which created a lot of mess inside the house, but when the
    crew was done, they left the areas clean. I would recommend Pinnacle Foundation to anyone needing foundation work done

    The entire Pinnacle Foundation Repair team is awesome!!!

    Mr. Cunningham was outstanding in conducting our initial foundation inspection providing us with whole house measurements and pinpoint recommendations as to how to remedy our foundation issues.

    Our repair team, spearheaded by Mr. Pena, Mr. Gonzales, Mr. Lalo, Mr. Daniel, and a host of others was exceptional! Each team member knew his role and responsibilities and immediately jumped into action upon arrival at our home. It was an extremely professional, well orchestrated team effort that resulted in a highly positive result.

    If you have foundation issues, you really should consider Pinnacle…we couldn’t be happier with the work they did for us!
    Professional, thorough & explained their process and findings. Jesse & Roy was exactly what I expected in a professional company. They performed a warranty inspection. They were knowledgeable about the property's history and work done. They took measurements and provided results quickly. Any questions I had, they responded with expertise and positive attitude to explain. I also appreciated that they were training a technician - always good to see hands on apprenticeship!

    Heather is one of the best people I have ever worked with! In the stress of buying a new home in Texas where foundation problems are so common I have never felt more secure in knowing someone had my best interests at heart to keep me and my family safe in our new home! Heather came out within a day of calling during my option period and provided a survey for free to make sure my foundation was in good condition! She offered to go over her findings line by line and answered all of my questions! If I ever do need foundation repairs in the future this company will be my first call! Highly recommend working with them!

    Five star service from start to finish. A huge thanks to the admin/finance team (Yvette & Kristen) for their outstanding communication. I was kept appraised with scheduling and payment milestones, which made the entire process stress free. Foundation repair is stressful, but Pinnacle made it seamless. Jason Cunningham did a very thorough initial inspection. The crew led by Ruben was very respectful, thorough and the work areas/landscaping was handled very well. The team worked diligently for 2 days to get the job done correctly. Punctuality was outstanding and site cleanliness was handled in a very professional manner. Roy Gonzales and Ruben's team stayed on schedule and kept me informed throughout the process. They provided clear communication, a solid warranty, which gave me peace of mind. Ruben and his team, along with Roy, Yvette, and Kristen need to be commended for everything they did during this process. A thankful customer, Luis Peña.

    I met with Brian Phillips for my evaluation and my foundation repair was completed by Mr. Roy Gonzales, Mr. Clint, and their team. Everyone was extremely professional, knowledgeable, organized, and customer service oriented. I couldn’t be happier with my experience with Pinnacle! I highly recommend contacting them for your foundation repair.
    Pinnacle did a great job on our foundation. Many of the cracks we had due to the shifted foundation has reduced in size drastically, and several doors the no longer closed or had difficulty closing now close with ease. They were also very professional, arriving on time, were courteous, and they were much more reasonably priced compared to all the foundation repair businesses we had estimates from.

    Once we received our quote ( which was the same dollar amount of other quotes, except it included a larger quantity and higher quality hybrid piers), we were quickly scheduled with lines located and an engineer's review. Jesse Pena and his crew showed up on time every day and were friendly, fast, professional, and very knowledgeable. They kept us informed of work and timelines every step of the way. It was a pretty big job and the work was completed in three days (as promised). By the afternoon of day three, our property was completely cleaned up, all debris hauled away, and it looked just as good as when they arrived. They even returned all patio furniture to original positions after thoroughly cleaning both patios. Before their team even left the site, we already noticed cracks inside closing up, doors opening and closing better, and floors more level (exercise ball and office chair (in different rooms) quit randomly rolling to the corners of their rooms). We are extremely pleased with the work they did and would recommend Pinnacle Foundation Repair to anyone considering foundation repairs.

    Brian came out yesterday to evaluate my foundation issues. He was through checking under/inside the house. When he completed the inspection, he sat down with us and had the recommended repairs displayed on his tablet outlining the scope of work. Excellent presentation giving visual understanding of the work needed. Brian was also able to provide the quote for the proposed work. Brian was professional and personable.

    Brian P was knowledgeable, personable, and thoroughly professional. The plan he laid out involves considerably more excavation than those of the other three companies we consulted, but at the best price. We are moving forward with Pinnacle, confident that we have finally found the best long-term plan to maintain the foundation of our hundred-year-old home.
    Excellent professional attitude and demeanor very cordial and knowledgeable.

    Excellent company! Brian was very professional in his evaluation of our foundation, and he gave thorough, honest feedback. A home inspector thought we might need foundation work, so we had Pinnacle come check it out. Brian confirmed that we actually didn’t need repair work as work that had been done in the past by another company was done well. He confirmed it with measurements and drawings. It is refreshing to encounter a company that has a high level of integrity and wants what is best for the customer. Pinnacle Foundation Repair is clearly an ethical company!

    Brian Phillips was knowledgeable, honest, and easy to work with. He clearly explained my foundation concerns and made me feel comfortable every step of the way.I never felt rushed or pressured. His straightforward approach made it more reassuring. We even ended up sharing grandparent stories, which made the whole experience feel more personal and trustworthy. Highly recommend Brian if you’re looking for someone you can rely on.
    John Campbell completed a foundation inspection for a home I am purchasing. He was amazing! He took the time to explain in detail the status of the foundation to help me make an informed decision on my purchase. He went above and beyond to help me track down details regarding the previous foundation repair. 10/10 will use Pinnacle Foundation Repair again and again and always ask for John!

    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.
