    Foundation Repair Sherwood

    Foundation problems can lead to significant damage to your home if not taken care of. Common signs to watch for include cracks in your floors, walls that bow, and sagging floors. Homeowners in Sherwood, OR may also notice doors that stick, windows that fail to close correctly, or visible gaps between walls and ceilings. These issues could indicate that your foundation is shifting due to soil movement, water damage, or aging. It’s important to address these symptoms promptly to protect your investment.

    At TerraFirma, we specialize in foundation repair in Sherwood, offering targeted solutions designed to address the root cause of your foundation issues. Our process starts with a thorough inspection to evaluate the extent and source of the problem. From there, we’ll recommend one or more of our trusted foundation repair systems:

    Foundation piers

    In Sherwood, OR, our push and helical piers are expertly designed to stabilize and lift your foundation by transferring its weight to deeper, more stable soil. Helical piers work best for familiar soil conditions, while push piers are ideal for areas with uncertain soil stability. Both solutions are minimally invasive and provide lasting results.

    Wall Stabilization Systems

    For cracked, bowing, or leaning walls, we offer a suite of reinforcement products. These include:

    • CarbonArmor®: Made from fiber-reinforced polymers ten times stronger than steel.
    • PowerBrace®: Zinc-plated steel beams that can be tightened over time.
    • GeoLock® Anchors and Helical Tiebacks: These systems halt inward movement and gradually straighten walls over time.
    • EverBrace™: Designed for severely deteriorated walls, this system replaces and reinforces failing foundation walls with steel supports.

    We also offer grouted micropile tiebacks for difficult soil conditions, SmartJack® crawl space support posts for sagging floors, and vapor barriers to manage humidity and prevent further moisture damage.

    Every solution comes with professional installation, ongoing maintenance options, and transferable warranties, so you can feel confident and at ease in your Sherwood home.

    Basement Waterproofing Sherwood

    Living in Sherwood, OR, you know how crucial it is to keep your home dry. A wet basement can lead to mold, mildew, structural damage, and poor air quality throughout your space. You might notice signs of water intrusion like musty odors, stained walls, pooling water, or efflorescence—a white, powdery residue that appears when water evaporates. Even a small crack in your basement wall can open the door for moisture troubles.

    TerraFirma provides top-notch basement waterproofing solutions in Sherwood, ensuring your space stays dry, healthy, and functional—come rain or shine.

    In Sherwood, OR, we design and install custom drainage systems that effectively redirect water away from your basement and into sump pumps, safeguarding your foundation.

    Basement Drainage System: Our most popular system, it’s installed below the floor slab and above the footing to prevent clogging.
    Perimeter Drainage System: Ideal for monolithic foundations where jackhammering is not feasible.
    Thin-floor Drainage System: A thin-floor drain system used in basements with thin concrete slabs.
    Grated Trench Drain: Block ground air from entering while allowing water to drain.

    We offer several sump pump options tailored to your water exposure:

    Multi-pump Sump System: Three-pump system for maximum protection, including battery backup for power outages.
    Battery Backup Sump Pump: High-capacity battery backup pump that activates when the main pump fails or power goes out.
    Basement Sump Pump System: A single-pump system for homes with minor water issues.

    Heavy-duty wall vapor barrier: A heavy-duty wall liner that stops moisture and mold while directing water into drainage systems.
    Basement Dehumidifiers: Energy-efficient dehumidifiers that remove up to 109 pints of moisture daily, improving air quality and comfort.

    Our Basement Window Well Enclosure and Window Well Drainage System keep your basement bright, dry, and free from debris, while meeting egress codes for safety.

    Waterproofing in Sherwood, OR not only safeguards your investment but also turns your basement into a safe and functional part of your home.

    Crawl Space Repair Sherwood

    Crawl spaces in Sherwood are often neglected, but they play a vital role in your home’s structure and air quality. If left unaddressed, a poor crawl space can become a breeding ground for mold, pests, and standing water. These problems can lead to wood rot, unpleasant odors, and even respiratory issues for those living in your home.

    We understand the crawl space conditions in Sherwood, OR, and TerraFirma’s crawl space repair services are tailored to tackle moisture, mold, pests, and sagging floors with comprehensive encapsulation, effective drainage, and robust structural support.

    Encapsulation & Drainage

    We begin by sealing the crawl space with our Vapor Barrier, a 120-mil thick waterproof barrier that blocks moisture, soil gases, and allergens. To ensure proper drainage:

    • We use drainage matting under the liner to guide water to your perimeter drain or sump pump.
    • Sump pumps remove water quickly and efficiently, even during heavy rain or high water table conditions.

    Concrete Repair Sherwood

    Damaged, cracked, or uneven concrete isn’t just an eyesore—it can be a safety risk too. These issues may arise from factors like inadequate soil compaction, freeze-thaw cycles, erosion, or tree root growth. That’s why Sherwood homeowners trust us to quickly and effectively repair their concrete slabs, sidewalks, patios, and driveways.

    TerraFirma provides quick, efficient, and durable concrete leveling and repair services right here in Sherwood, OR, utilizing advanced polyurethane foam injection and expert crack sealing.

    PolyLevel® Concrete Lifting

    PolyLevel uses expanding polyurethane foam to lift and stabilize concrete slabs. This non-invasive method is perfect for homeowners in Sherwood who are looking to repair:

    • Sidewalks – Eliminates tripping hazards and restores smooth walkways.
    • Driveways – Prevents further cracking and improves curb appeal.
    • Patios, Porches, and Pool Decks – Ensures proper drainage and surface stability.

    NexusPro™ Crack & Joint Sealant

    To prevent water intrusion that can lead to further sinking, we apply NexusPro, a UV-resistant silicone-based joint sealant that:

    • Cures in just 60 minutes.
    • Withstands extreme weather and heavy use.
    • Includes color-matched sand for a clean, polished look.

    SealantPro™ Concrete Protection

    After sealing and lifting your concrete, SealantPro provides a long-term barrier against moisture, chemicals, and seasonal temperature changes. It penetrates deep into concrete to resist stains, flaking, and surface erosion.

    We also provide commercial concrete repair in Sherwood, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.

    Earthquake Retrofitting Sherwood, OR

    Sherwood, like much of the Pacific Northwest, is situated in an active seismic zone. Homes built before the updated building codes of the 1990s may be particularly at risk. Even a minor earthquake can lead to your home shifting off its foundation or suffering significant structural damage.

    TerraFirma’s earthquake retrofitting services help secure your Sherwood home to its foundation and strengthen its ability to withstand seismic events.

    Retrofitting your home for earthquakes in Sherwood can help lower your insurance premiums and deductibles, and may even make you eligible for coverage that wasn’t available before the upgrade.

    How We Retrofit

    Assessment & Planning

    In Sherwood, OR, the retrofitting process starts with a thorough assessment of your building’s current condition. A knowledgeable expert, like a structural engineer or trained technician, will inspect your home to pinpoint any weaknesses and suggest the best solutions tailored to your needs.

    This assessment covers the foundation, walls, roof, and overall structure of your home. After that, our engineer will create a detailed retrofitting plan tailored to the results.

    Foundation Bolting

    Securing the foundation is a crucial next step for homes in Sherwood, OR. Our technicians expertly install anchor bolts to firmly connect your house to its foundation, helping to prevent any lateral movement during an earthquake.

    Our process begins by drilling holes into your foundation and inserting sturdy steel bolts. Our team then tightens these bolts to reinforce your structure, increasing its stability and ability to withstand seismic forces.

    Adding Shear Walls

    Shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces and keep structures in Sherwood safe from collapsing.

    Shear walls, usually made from sturdy materials like plywood, are strategically placed throughout homes in Sherwood, especially in areas known as cripple walls. These additions enhance the strength and stability of your walls, helping to minimize the risk of damage during an earthquake.

    Bracing & Reinforcing

    Next, we enhance and strengthen vital areas of your home in Sherwood with durable steel braces and straps. Our team expertly installs these reinforcements on essential structural elements like the roof, walls, and floors. This crucial step boosts your home’s stability, creating a robust framework designed to withstand seismic activity.

    Securing Appliances

    Securing your appliances is key to creating a safer home for everyone in Sherwood, OR. Anchoring essential items like water heaters and refrigerators can make a real difference. Our technicians can also provide protection for gas meters to help minimize the risk of gas leaks.

    Repairing Foundations

    During retrofitting, technicians may notice substantial foundation damage that needs immediate repair. Adding crawl space support posts and foundation piers, and stabilizing the walls are some of the ways TerraFirma can reinforce your foundation.

    We had our sump pump serviced and our encapsulated crawlspace inspected. Clay was very thorough, professional, and helped us identify other areas to watch out for in our home. Our service was scheduled by Michael who was very prompt and helpful as well. Many thanks to Clay and Michael!
    Nate and his crew went above and beyond on the project and I'm so glad I decided to work with TerraFirma! The team was punctual, efficient and very professional! In addition to lifting my house and adding supports, they also flattened out the ground around my craw space, added pipe insulation and let me know about a leak under the house. I will definitely be recommending TerraFirma to others!
    Their service was great from Eric doing the quote to the crew that completed the project.
    I appreciate that they have workers that have been with them for long periods. Timothy kept me informed every step of the way, and Spencer, Filipe, and Jose were respectful of my space. Jonah was a good manager, and the project was concluded on time and budget.
    It is very rare to find a company that is excellent from the very first encounter to the last phone call. Every person at Terra Firma has been attentive and kind, but most of all they have taken the time to explain their process and to do the highest quality work. The crews took pride in their work and knew their craft, answering my questions in a thorough manner. I felt compelled to write this very positive review because so many times only negative people take the time to express their opinions. This company lives up to their commercials and quality of work. They're local and we should all support this local business when we can.
    Wanted to share my experience with fixing a flooding issue with Terrafirma. Right from the get go of setting up the appointment, followed by the onsite estimate and scheduling the project and the crew arriving, it was such an excellent experience. The crew with foreman Luis, and his cohorts Casey and Jairo were awesome. They explained every detail of what they were planning to do and being open to taking inputs and adjusting things and completing the project right on time. And finally Luis demonstrated the system working and I can't put in words the sheer joy of having a dry garage and no fear of water seeping into the utility room.. A giant thanks.. Highly recommend Terrafirma and this awesome crew.. -Ramesh
    I can't say enough about the professionaism of Louis,Sebastian, and Jairo.They were very courteous,explained the process step by step &when they were finished supporting my floors the cracks in my walls had all but disappeared! l very highly recommend Terra Firma!I couldn't be happier!!! So glad I called them!
    Edit: Jan ‘26 Unfortunately this sump pump did not solve the problem after all, as water again came in after several days of hard rain. To be fair, TF did not guarantee a solution. I still think it is a good company but sadly my problem persists. Previous review from Nov 25 - Terra Firma installed a sump pump in my home that has solved my water incursion issues. This had been a problem for months. I had several different companies and professionals out to evaluate and try to solve the problem, from plumbers to leak detection companies and a few more. Most scratched their heads and said "this is a mystery." Terra Firma came up with this solution and it is working. I wanted to wait until we had significant rain to write this review - and after the past few days of pretty good rain, and no water coming in - I feel confident that the problem was solved. They were helpful, considerate and creative. They didn't try to sell me more than was needed. I recommend Terra Firma.
    TF crew did a fantastic job despite a misunderstanding about a small area by the front door that was excluded in the proposal. We are extremely pleased with the results. Obviously, we need to evaluate the results during and after this winter, i.e., when the flooding is likely to occur.
    Will came out, today, to give us an estimate. He did a thorough inspection and explained everything in laymen's terms, as he went. I also appreciated that he didn't try to sell me on services that I didn't need but was honest about what our options were. I highly recommend Terrafirma!
    The guys were real efficient and professional. We’ve used Terra Firma for close to 10 years and it’s always a positive experience.
    Marcus and the Terra Firma team were extremely professional and helped us find a cost-effective solution to our sump pump replacement. I would recommend Terra Firma to anyone who needs help with home waterproofing needs.
