No matter how small it might be, even a little damage to your foundation will reduce your property value, and it can lead to dangerous structural issues. If you notice wall cracks in your home, they may indicate an underlying foundation problem. Together with drywall nail pops, uneven floors, and sticking windows, signs of potential foundation failure might be all over your home. If you think that your house is in trouble, call the experts at [brand] for a comprehensive inspection of your home. We have proven solutions to restore your foundation, and we have the warranties to back them up. For more information or a free estimate, visit our website today!

Problems like mold, mildew, high humidity, and standing pools of water are all signs that your home’s crawl space is in need of repair or crawl space encapsulation. Our crawl space repair solutions can keep your crawl space free of pests, mold, and mildew, and can help regulate temperature and moisture levels in your home. For more information or a free estimate, visit our website today!

Exterior sunken concrete patios, driveways, and sidewalks are frustrating for homeowners across the country. PolyRenewal™ is the perfect concrete leveling solition. It's a lightweight, high-density polyurethane foam that goes beneath concrete slabs. It quickly expands and hardens, lifting cracked concrete slabs back into place. If you’re concerned about sinking concrete, call today or visit online to schedule a free home inspection.

While it is common for most basements to have moisture issues, they shouldn't be ignored. Basement water and moisture management problems negatively affect your home’s health and structural integrity. Call or visit us online today to schedule a free inspection and find out more about our basement waterproofing solutions.

Crawl space encapsulation creates a dry, hygienic, and safe interior space beneath your home that repels moisture and allergens. This can be achieved in many ways, but the main key component is a thick, durable vapor barrier to seal out the moisture from getting in. Encapsulation protects your property and creates a healthier interior climate for your entire home.

    Groundworks sent out Will Watters to do an inspection of our crawl space needs. He did a very thorough job, and went over his estimate in detail. You could tell that he was very experienced, and professional in every way. He was also very polite and listened to all of our concerns and questions about how the work would proceed and what each cost covered.

    Matthew Wyatt came out to service our system today, & he was fantastic! We have a basement system installed by Groundworks back around 2019 including an interior perimeter drain & a sump pump. At the time, the company was called Rainy Day Basement Systems, & they did a really good job. Matthew came out today to service it & was great. Very communicative, on time, friendly, & even made me aware of a 5-yr contract that will end up saving me money on this maintenance in the future! Thanks Matt!

    Just had the front sidewalk in Southwest Washington lifted back into place. Bailey and his co-worker did a fantastic job! They used equipment called a Slab Jack, as the cement was four inches thick and had been sunken for several years. They worked efficiently while keeping us informed of the process, finished and cleaned up in less than two hours. It was a pleasure working with everyone in this company from the gentleman who bid the work, the schedulers willing to work around our availability, to the final results. We highly recommend them. Thanks, Groundworks!

    Three years ago I had a crawl space rehab and drainage system installed. It has worked flawlessly. The company is responsive to my concerns and comes out for yearly inspection and maintenance on the sump pump system. Today service technician Matthew Wyatt was very professional, clear in his communications and took the time to explain in detail all of his findings - very thorough and never rushed. Highly recommended!

    Matthew Wyatt was extremely helpful. He explained everything he was going to do. Answered all our our questions. Explained in detail about the cracks in the foundation and Temperature changes. Paperwork and warranty and how the warranty can be transferred to the next owners. He crawled under the house to inspect the prior work and made adjustments. Then changed out the power cord to match the house. Matthew was very professional and knowledgeable, we look forward to working with him on our next improvements. Thank you
