Previous Project Experience

Common Causes of Structural Failures
Material failure: Failures can occur due to the failure of materials used in construction, including steel, concrete, or timber. Factors like corrosion, fatigue, or manufacturing defects can contribute to material failure.
The biggest red flag in a home inspection is compromised structural integrity, frequently caused by hidden water damage or foundation issues. While minor electrical or plumbing fixes are easy to manage, structural failures compromise the safety of the entire home and can cost tens of thousands of dollars to repair.
