What Is Included in a Home Inspection

Old Line Home Inspections in the News
View detailed information on the different types of inspections we offer, and what each one covers.


We are first time home buyers and we were nervous about buying a home that had lots of structural issues that we didn't notice. Admittedly we don't have a lot of knowledge when it comes to knowing what to look for.

Andrew was the key to the entire home buying experience! He is incredibly knowledgeable and was able to figure out what every weird looking set up the house had and find all the good things and not-so-good things.

His inspection was more thorough than I could have imagined and let me walk around with him the entire time so I could learn, see the issues, and ask questions. I really felt by the end of the appointment there was no stone unturned.

The best part is I could tell he really cared. He went back multiple times to double check things. He wanted to make sure he got it right. He worked so hard in getting on the roof, he didn't want to rely on pictures, he wanted to get up there and see for himself what was going on. He even offered to take a mold sample when some was found, which turned out to be such important information for the negotiation process. I could tell he really wanted us to have all the knowledge we needed in the home buying.

The report was so great! It was easy to read, and gave us a great perspective of what needed to be done. The pictures were great and he took lots of them! Our realtor was impressed!

We plan on using Old Line Inspections from now on and will also choose to recommend them when someone asks. Highly recommend choosing them for your home inspection!

It was our first time buying a house of our own, and we know that for sure the Inspection of the house is the most important thing to be done of all. So, we gave contract to Old Line Home Inspection, the best part of Andrew was, he was not only professional but also very experienced and knowledgeful, not to forget he has done this in really affordable price. He helped us to understand the problems and also showed us the severity of them. He also helped us prioritized the work need to be done. I would highly recommend him to anyone who wants their properties to be get inspected and with perfection.

I had a great experience working with Old Line Home Inspections. I was referred to them by my realtor and worked with Andrew. He did a thorough job and answered all of my questions and gave tons of helpful tips throughout the inspection. Not only on the home itself, but on local contractors and how much things generally cost to fix.

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.

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.

My husband and I contracted Old Line Home Inspections to perform a detailed due diligence inspection prior to finalizing our purchase of an existing home. Andrew exceeded our expectations with his deep knowledge and thorough inspection of the house and property. We also appreciated Andrew's very calm and personable approach and level of integrity in his discussions with us as well as his insights as to possible causes and solutions to those items he uncovered. We would very highly recommend his services to anyone.

Andrew helped me on my 11 month inspection for my new home. He was patient and did a though job. He spent time on the inspection and wrote a professional report. He also followed up to answer my questions. I should have hired him when my home was starting to be built. He is one of the best construction contractors I have hired. I am very happy with his work and would highly recommend him to anyone.

Andrew performed home inspection on a property I was interested in. He was on time, prompt, and gave me good feedback on the condition of the home. He is very prompt in his communication, and sent me the final detailed report within 24 hours of the inspection. He patiently answered all my questions during my inspection, and also raised important FYI's for me to see, and suggest possible changes. I will hire Andrew in future.

We needed home inspection for our newly built home in Frederick, MD before the final settlement. Andrew was able to provide the service. He was already at the site when I came by examining the exterior thoroughly. He took his time and went through the house with fine tooth comb. He was professional and competent while conversing with me throughout the process of inspecting our home. I was very satisfied with Andrew's work and thought what a blessing it was to have encountered him. I recommend Andrew highly for his knowledge and expertise

We are in the process of buying our first home and used Old Line Home Inspections for a home inspection that included a termite inspection because of damage we discovered on the porch. We were able to rule out termites but found wood rot damage that was even more serious than originally thought. While his assessment was a shock to us initially, Andrew set our minds at ease by confirming that once the porch support structure was repaired, we would not have any more problems. After inspecting the rest of the house, we also discovered a few more items that needed repair and we were able to determine what items needed to be repaired first. I cannot impress enough about how much of a relief it was to know the extent of the repairs that would be needed and that our house would be safe and sound.

As a real estate agent, I can tell you that Andrew Winnard has become my "go to" home inspector. There are so many things that are important in finding a good inspector and Andrew has all the characteristics that I look for. He is always on time, in fact he is usually there before I am. He knows city row homes just as well as he knows county detached homes. And if there is a way, he'll get on the roof! He has experience in septic and well systems. In just a short period of time, through his thorough inspection reports he has taught me about outlets, double tapped breakers, polybutylene pipes, water cleaning systems, termite mud tubes, plumbing boots, chimney liners, and more! His knowledge goes across the spectrum and makes my clients feel comfortable asking questions. I have called him to ask about certain repairs and he is always quick to return my call. His friendly nature is also great at reading my clients. He is good with first time home buyer's FATHERS! You know the ones that think they are inspectors. And at the same time he is patient with the super smart "Engineer" types that require seeing everything. He is good with clients that don't know what to ask. Andrew always points out good maintenance practices, like keeping a backdoor drain clear or how easy it is to grade the grounds. You know you are a good home inspector when I get referrals who say, "I was told to call you and make sure you call Andrew for my inspections!"

Andrew is the best! He was on time, professional & wrote a detailed home inspection with pictures included. I shopped around for 2 days looking for a reasonably priced home inspector that could fulfill all my needs including termite & radon test. I found his company online and researched to find positive feedback from others which let me know I could confidently give him a try. He surpassed my expectations he presented 5 star service and when I had specific questions after my inspection regarding my roof, heat pump & ac unit Andrew gave me more helpful info. I’m so thankful he was available within my 10 day deadline to conduct my new home inspection as I will definitely refer him to friends & family.

I am a first time home buyer. I came across Old Line Home Inspections for it’s 5 star reviews and because it was close to the house we were purchasing. Andrew was right on time and got to work immediately. His level of customer service was outstanding. He took his time and took photos of every angle of the house to include on the report which by the way was very detailed. He even stayed after the inspection was done to make sure my questions and concerns had been answered. I enjoyed working with him. Thank you Andrew for your services. I highly recommend this company if you are looking for a home inspector in the Baltimore area.

Our family was purchasing a home in as is condition with a small window of time to inspect property for pre-existing conditions. A found Old Line Home Inspections through an internet search, emailed them, and Andrew responded within the hour. He gave a great price and was able to work me into his schedule. I was extremely impressed at the thorough and very detailed inspection he provided. He pointed out small issues that were easy fixes but not critical to the condition of the property. Before leaving, he gave a verbal summary of his findings and the next day, as promised, I received the very professional and detailed report of his inspection. Very, very pleased with Old Line Home Inspections and the owner, Andrew. I highly recommend him.

Andrew did a great job providing us with a detailed, easy to read, easy to understand, comprehensive report about our new construction townhome that contained pictures of every issue. He found several issues that we would not have been able to diagnose on our own. He was also very pleasant to work with and available for questions after the report, and he gave his report to us in a timely manner, just like he promised.

I was so happy that my realtor recommended Andrew and Old Line Home Inspections during my recent home purchase. Andrew was responsive, on-time, and well-prepared for the inspection. He took the time to look at every detail of the house, and was very patient to explain the construction and details of the house, even if I asked the same question a few times. Andrew did not rush, was very trustworthy in his analysis, and seemed very passionate about home construction and care for the home. Andrew provided thorough feedback as we walked through each room within the house, and presented results in a report that included photos, problem statements, and recommendations. Old Line Home Inspections is miles ahead of any other inspectors I have had used in the past when purchasing a home, and I will always use them again for my future purchases, or when an inspection may be needed.

Our family is so happy to have found Old Line Home Inspections. On two occasions, we needed an inspection done quickly and Andrew accommodated us. He is very organized and a good communicator, making scheduling easy. Andrew was incredibly thorough and explained his findings before sending us his report.

I price shopped around and spoke with several inspectors, but felt comfortable speaking with Andrew about a home inspection. I needed a home in Ellicott City inspected and Andrew did a really thorough job. Overall, he's very honest and thorough with his work.

Where do I even begin? Andrew provided exceptional customer service from our first conversation through receiving our report. He was thorough and it is very clear that he knows what he is doing. Upon finishing, he walked us through the house and explained everything he found... as well as how things functioned in our home. We also received a VERY detailed report PROMPTLY. From customer service, to knowledge, to professionalism... he does does it all and earned every star given! Hands down I highly recommend Andrew for your home inspection needs.

Andrew inspected my house front to back, inside out, doors, roofing, driveway, sidewalks, the yard, electric, water, water heater! Bathrooms, windows, hvac, sumppump, everything in a house to be efficient and safe. A very detailed and concise inspection.
