What does a foundation inspection involve?
A comprehensive inspection involves a thorough visual assessment of both the interior and exterior of your property. We examine the foundation walls, slab and crawl space for signs of distress such as cracks, bowing or water damage, and we check for uneven floors and sticking doors or windows. We also evaluate soil conditions and drainage around the home. A professional inspection is the first step toward identifying the root cause of a problem and choosing the most effective repair.
What are the signs my foundation needs repair?
Look for cracks in your walls or floors, uneven or sloping floors, sticking doors or windows, and water intrusion in the basement or crawl space. If you notice any of these issues, it is a good time to schedule a professional inspection.
