Structural problems with the foundation or roof, water damage, and significant plumbing or electrical issues are all considered major red flags in a home inspection. Of these, a structural problem related to the foundation is often the most severe. Foundation repairs are typically the most expensive and intrusive to carry out, averaging around $5,000 but sometimes reaching up to $16,000. Because these problems can pose safety risks and be costly to fix, you should ask your inspector detailed questions about any identified issues. You will need to carefully consider how major problems affect what you’re willing to pay for the home, or if you want to proceed with the sale at all.

Some of the signs that could mean your water is contaminated, such as cloudiness or bubbliness, could also be non-problems that don’t affect your water’s potability. However, if your water smells or tastes strange, it’s a good idea to stop drinking it and test it immediately. If your well water is contaminated, the best way to discover that is to test it.

Lead exposure poses significant health risks, including neurological, developmental, and behavioral disorders, especially critical in young children and fetuses.

If lead is detected in a property, steps should include arranging for professional removal or containment, notifying all occupants, and implementing interim safety measures to reduce exposure.
