You can sell a house with lead paint, but there are several requirements. If you are aware that lead paint exists anywhere in the home, you must disclose that to potential buyers. Required home inspections will often uncover lead paint, especially for older houses where lead paint may still be a problem. If you have taken steps to encapsulate lead, you should provide buyers with full documentation of the project so it won’t cause any problems later on.

DIY lead testing kits are available, but they often lack the accuracy and reliability of professional services. Professional testing is recommended for more accurate results, as properly certified testers can provide a thorough analysis, clear recommendations, and the necessary legal documentation if remediation is required.

The average cost of a lead paint inspection is about $600, but it can cost as low as $150 or as much as $800, depending on the size of the area, geographic location, and the inspection methods. Some of the most common lead paint inspection methods include:

• Visual inspection: $150–$400

• Paint sampling: $200–$600

• X-ray fluorescence (XRF): $250–$700

• Risk assessment: $300–$800

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.
