"The sales man offered me leveling and light of my foundation. The end result was my doors not being able to close, more cracking in my sheet rock on the walls and on the ceiling. The house is not level and now Iâ  m seeking options to fix this whole debacle. Ram Jack West is sales based, not service based. Please do research before you make a $30,000 to have hire a company to repair your foundation, working with them is one of my biggest lifetime regrets."

Since 1987, Groundworks has specialized in helping homeowners with their foundation repair, waterproofing, and concrete needs. Our top priority is providing high-quality home repair solutions and personalized service across North-West Washington. With fully trained technicians, industry-leading products, and nationally backed warranties, Groundworks is here to restore your basement, foundation, or crawl space.
"I don't leave a lot of reviews, but the Groundwork crew and the encapsulation work are exceptional, so here goes. We have a pretty large crawl space under our 30-year old house. The team (Wyatt, Zane L. And Volodymyr M.) worked really diligently to get the 5 day job done. They managed a huge amount of cleared-out debris, and thoroughly cleaned up all of the construction material after they installed. No sign of any dust, garbage or debris after they finished the job. Not even a staple. The encapsulation looks fantastic and it's so nice to have the area dry, insulated and clean. Oh, and they were able to install the dehumidifier in a place that is easily accessible when we need to clean the filter. Just really glad we decided to do this. Wyatt S. Went out of his way to keep us well informed of when the team coming each day, when they took breaks and when they were going home at night. He shared progress photos each day and addressed all of my concerns. I've worked with many contractors and these guys are at the top of their game."

On average, it takes two to seven days to physically raise your house. However, this does not include the preparation work, which is often the most lengthy process. The entire project, including preparation, obtaining permits, disconnecting utilities, and any subsequent landscaping, can take four to eight weeks. This timeline ensures everything is done safely and that your home remains structurally sound.
If proper safety protocols are not followed, raising a house can cause severe damage, as the process involves applying controlled force to the home's structure. The risks involved make it crucial to hire a skilled contractor who uses engineered methods to secure your home and prevent any harm to your household.
If your foundation shows signs of instability after raising your home, you might need to add structural support. A structural engineer can assess your foundation and recommend reinforcements to ensure your house stays stable and safe for the long term. Available support options include installing additional piers or pilings, reinforcing existing footings, or using steel beams to distribute the load more evenly.
You will need a structural engineer to assess your home before you begin. These professionals determine whether your house is suitable for lifting and identify any issues that could compromise its stability. Their expertise ensures that the project is designed correctly and all risks are managed to achieve a successful lift.
