Non-destructive XRF inspection identifies lead-based painted components in pre-1978 homes so buyers understand where lead is present before closing.
LEAD PAINT
NRPP-certified continuous radon measurement documents indoor conditions during the real-estate transaction using calibrated monitoring equipment.
RADON
Targeted suspect-material evaluation and laboratory sampling, when appropriate, help buyers understand materials that may affect planned renovations or ownership.
ASBESTOS
ONE CALL. ONE ENVIRONMENTAL PROFESSIONAL. ONE DUE-DILIGENCE PROCESS.
A general home inspection does not answer every specialized environmental question. HarborLight coordinates lead paint, radon, and targeted asbestos due diligence through one independent consultant—so buyers receive clear scope, professional documentation, and direct answers before closing.
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.

We had Mike come and inspect our house for lead. He came over at my first availability and went through my house very thoroughly! I highly recommend HarborLight for all of your inspection needs! They are incredibly knowledgeable, professional and helpful.

I highly recommend Mike and HarborLight Property Inspections. I have high standards and seek quality service. This means that I have high expectations for a company being responsive, providing timely and effective communication, understanding and placing the client's needs first. Mike exceeded my expectations on all fronts. It feels that there are fewer and fewer companies and business owners today that hold themselves to a high standard. I'm glad to say that Mike and HarborLight Property Inspections is bucking that trend.
