"Gauge is a Representative who puts his Clients first. He reminds me, of a younger me. (This says a lot, because I was always a top notch Sales Rep and I retired early, as a result of my personal efforts and how I always did, as I said, and placed my Clients as top priority). I have yet to begin my project, but he won over my business and I?m excited to see the results. I?m confident they will exceed my expectations."

FAQs for concrete foundation raise projects in Sammamish, WA

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.
