Michael was exceptional. I hired him to conduct a lead inspection, and his work was incredibly thorough and professional. Once the report was completed, he remained readily available to answer any questions I had, always responding promptly and thoughtfully. Not only did he provide a comprehensive and detailed report, but he also connected me with qualified professionals who could assist with remediation efforts beyond his scope of practice. His expertise, responsiveness, and willingness to help throughout the entire process were greatly appreciated. I highly recommend Michael's services without hesitation.

Lead Hazards in Maine Homes
Many homes built before 1978 in Maine may contain lead-based paint, especially properties with original windows, doors, trim, stairs, siding, or other historic building components.
A lead inspection should be considered if your home was built before 1978, contains deteriorating paint, has high-friction surfaces such as windows, doors, and stairways, or if children under the age of six live in or regularly visit the property. When lead-based paint deteriorates or is disturbed during renovation, invisible lead dust can be released into the home environment.
The good news is that several testing methods can identify potential lead hazards, including XRF Lead Paint Inspections, Lead Dust Wipe Testing, Lead-in-Soil Testing, and Lead-in-Water Testing. A comprehensive evaluation often combines multiple testing methods to provide a complete picture of lead risks and help protect your family, tenants, employees, or future occupants.
HarborLight Property Inspections provides certified lead inspections across Southern Maine, specializing in pre-1978 homes where lead-based paint hazards are most common.
We are Maine DEP Licensed Lead Inspectors (License #LO-0020), providing XRF lead paint testing, limited lead-safe certificates (LLSC), and compliance inspections for real estate transactions, insurance requirements, and property owners.
Our inspections go beyond basic testing. We apply building science and real-world experience to identify lead hazards, interpret results, and provide clear next steps.
From Portland to Biddeford and across Southern Maine, we help homeowners, landlords, and investors make informed, confident decisions.
