As founder and owner Old Line Home Inspections, it is my duty, and my privilege, to provide you with the best service possible and to arm you with the information you need about the condition of the property. I am an AHIT Trained, InterNACHI Certified Professional Inspector (CPI) with over 1,000 continuing education hours and over 30 advanced certifications to better serve you. Being a native Marylander and local businessman, I have over 20 years’ experience in the Central Maryland real estate community where I have lived raising my family for over 25 years.

We encourage you to be present during the inspection. You’ll be able to see the condition of the home first-hand, and I’ll be able to explain everything to you as we move throughout the house. Take advantage of this time to ask questions since good communication is crucial to a complete home inspection. Your time is important to us and we take pride in knowing that if we do our job right you will have the security you need to approach the purchase of your new home with confidence.

I am a realtor and we used Old Line Home Inspections for my clients who are buyers for a home in Baltimore City. The inspector was great. Very thorough and professional. I would recommend him again!

Old Line Home Inspections inspected our new home after our offer was accepted. Andrew was amazing. He was on time and very professional and knows his stuff. He noticed everything that was wrong in the house and gave us a great Inspection Report so that we could follow-up on all repairs.

Mr. Andrew Winnard is very professional. He is extremely detail-oriented and is willing to spend as long as it takes to do a thorough examination of the house. In my case he spent over 2 hours doing the inspection, going through all aspects in great detail, answering all my questions, and then sent me a final report on the same day. I highly recommend him.
