"Wow. What can I say about this company. My father passed away recently and left us his house, which needs major foundation repairs. It’s all my Dad had left to leave his kids, and his grandkids. So with the life insurance he left, we decided the foundation needs repaired. Went online and found Groundworks. The first day I met with Matt Gumpert, for a free quote. He went over EVERYTHING in perfect detail. In the beginning, he made sure I understood everything about Groundworks and what they do. How they operate, and why he does what he does. He spent well over an hour in my crawl space making sure to note every detail along the way. He was in my dining room for quite a long time, going over options of what needs fixed and what we could afford, and honestly, he felt like a part of the family. He was totally professional, but also has a way about him of putting you totally at ease with a stranger. Never ever put any pressure on me at all, and didn’t use any scare tactics to push me into going with their company. At one point, our permit got rejected by an engineer and he spent all day sorting out the issue and really eased all of my concerns. He got it to a geotechnical engineer instead and there were no more issues. Unfortunately in the process of waiting for the city to approve permits, some unexpected financial issues hit us and we had to put the project on hold. I contacted Matt and he didn’t make me feel bad. He totally understood how hard things have been for us without my Dad around, and worked hard to get us most of our deposit back as well. Even though we did not get the project done, in the future when I have the funds, I will definitely be contacting Matt Gumpert at Groundworks again for all of my foundation needs. I wouldn’t trust anyone else with the project, or with my Dads legacy."

Common Causes of your Basement Problems in Seatac

Ever wondered why basements in this area often show signs of wear and tear? Homes in and around Seatac experience unique environmental factors that affect their foundation's integrity. The regional climate, characterized by frequent rainfall and seasonal moisture fluctuations, interacts with the clay and silt-rich soils found in many neighborhoods. During heavy rain, soil expands, exerting pressure on basement walls, known as hydrostatic pressure. Conversely, dry periods can lead to soil shrinkage, creating gaps that allow for unwanted movement and settlement in your home's foundation.

These natural forces stress your basement over time, causing cracks in walls, uneven floors, and doors that stick. Excess moisture can seep through weakened areas, leading to problems like rising damp or mold, which are common in local properties. Pooling water near your foundation can be a red flag for poor drainage or blocked gutters. Noticing these issues early can prevent potentially expensive repairs, as even small shifts in your foundation can snowball into significant damage. Regular inspections help detect threats to your basement's structural health and preserve your home's long-term value.

Yes, homeowners can perform a preliminary inspection of their basement for signs of damage. Look for cracks in the walls or floors, signs of water intrusion such as mold or mildew, and any unusual odors. However, it is advisable to have a professional inspection to accurately assess any structural issues.

Seatac's seasonal weather can have several impacts on basement walls and floors. During the rainy season, increased moisture can lead to water intrusion, which can cause walls to crack or become damp. Freezing temperatures can also contribute to expansion and contraction in building materials, potentially leading to cracks or other structural issues.

Water can cause materials to deteriorate, lead to mold and mildew growth, and increase pressure against walls, which may result in cracks or bowing. Addressing water intrusion promptly is crucial to maintaining the integrity of your basement.

The duration of a basement wall repair project can vary depending on the extent of the damage and the repair method used.
