Our Expert DIY Tips for Foundation Inspections: Step-by-Step
A solid foundation is critical to your home’s stability, and catching early signs of foundation damage can prevent costly repairs. If you suspect foundation issues, a DIY inspection is a great first step. Knowing what to look for and having the right tools can help you determine if professional evaluation is necessary. Below, we’ll cover what you need before starting your inspection, the key warning signs to watch for, and a step-by-step guide to assessing your home’s foundation.
What You Need Before Inspecting Your Foundation
Before starting your DIY foundation inspection, gather the right tools to accurately assess potential issues:
- Flashlight – Helps you check dark corners in basements and crawl spaces.
- Level – Essential for spotting sloping floors and uneven surfaces.
- Tape Measure – Useful for tracking crack growth over time.
- Notepad or Mobile App – Keeps a record of any issues you find for future reference.
- Screwdriver – Helps test for rotting wood or soft spots in crawl spaces.
- Marble or Small Ball – A simple way to check for sloping floors by seeing if it rolls on its own.
Documenting your findings, including measurements and photos, will help track changes over time and provide valuable information if you decide to consult a professional.
IMPORTANT NOTE: Environmental factors like rising water tables can lead to foundation issues. For example, a U.S. Geological Survey study reported basement flooding and foundation damage in Brooklyn due to increased water-table levels. Being aware of such factors can enhance your inspection’s effectiveness.

Knowing what to look for is key to a thorough DIY foundation inspection. Here are some of the most common signs of foundation damage:
Common Signs of Foundation Damage:
- Cracks in Walls or Floors – Small hairline cracks are normal, but widening or stair-step cracks can indicate foundation movement.
- Uneven or Sloping Floors – Use a level to check for dips or slopes in different rooms.
- Sticking Doors and Windows – Difficulty opening or closing them could signal foundation shifting.
- Gaps Around Doors and Windows – Separation between frames and walls may point to settlement issues.
- Moisture or Water Damage – Inspect your basement or crawl space for signs of leaks or excess humidity.

Step-by-Step Foundation Inspection Guide
Follow these steps to conduct a thorough DIY foundation inspection:
- Walk the Exterior – Look for cracks in the foundation, gaps between bricks or siding, and any noticeable settlement.
- Check the Interior Walls and Floors – Inspect for cracks, bulging walls, or sloping floors using a level.
- Test Doors and Windows – Open and close them to see if they stick or if gaps have formed.
- Examine the Basement or Crawl Space – Look for water damage, mold, or signs of shifting beams.

Common DIY Foundation Inspection Mistakes to Avoid
While inspecting your foundation yourself is useful, common mistakes can lead to foundation check errors, misdiagnosed issues, or overlooked warning signs. Avoid these common pitfalls:
- Ignoring Small Cracks – Minor cracks can expand over time and cause serious structural problems.
- Not Checking the Entire Perimeter – Damage can be subtle and often appears on different sides of the home.
- Overlooking Drainage Issues – Poor drainage is a leading cause of foundation damage. Look for water pooling near the foundation.
- Misinterpreting Cosmetic Cracks – Not all cracks indicate structural failure, but some do. If unsure, consult a professional.
- Skipping Regular Inspections – Foundation shifts can happen gradually. Consistency is key.
A DIY foundation inspection is an excellent way to stay ahead of foundation issues, but if you’re uncertain about your findings, getting a second opinion from an expert is always a smart move.
When DIY Inspections Aren’t Enough: When to Call a Professional
DIY inspections help catch minor issues early, but certain signs mean it’s time to call in a home foundation expert for a professional foundation inspection:
- Cracks Wider Than ¼ Inch – These could indicate serious structural movement.
- Floors Sloping by More Than an Inch Over 10 Feet – A sign of significant foundation settling.
- Doors/Windows That Won’t Close Properly Even After Adjustments – Could indicate shifting or sinking foundations.
- Water Pooling Around the Foundation – Excess moisture weakens foundations and can cause cracks.
- Mold or Moisture Problems That Persist Despite Fixes – Often linked to foundation cracks and poor drainage.
If you spot any of these red flags, scheduling a foundation repair consultation can prevent further damage.
