The purchase of real property, whether a single family home or a condominium unit, is the single largest investment most of us ever make. Who do you trust when seeking the assistance you need to be assured the property is not going to be full of surprises when you become the new owner? Finding a home inspector is not a simple task.

Are they qualified? Are they experienced? Do they have a proven track record of accuracy and thoroughness? Are they properly certified by an independent third party? Do they agree to keep the report confidential and not share or discuss it without your permission? With more than 40 years of experience providing home inspections in the Washington DC metropolitan area, you can have faith that we provide helpful and accurate inspection reports.
Services
Call (301) 588-1318 to schedule your inspection. Our office is open Monday through Friday, from 9:00 A.M. through 5:00 P.M. Inspections are conducted Monday through Friday mornings or afternoons. Most inspections take three to four hours to complete. We offer a convenient digital multi page report that includes embedded photographs of the areas of concern.
Partial inspections to diagnose specific problems are also available.

Perhaps your roof has begun to leak and you don't know if you need an entire new roof or just a patch; or perhaps your basement floor is suddenly wet and you can't find where the water is coming from or don't know how to stop it; or perhaps you've hired a contractor to construct an addition and his work seems questionable to you so you'd like the work evaluated before you release the contractor's next draw.
Sean Troxell has worked with investigators at the Montgomery County Office of Consumer Affairs; as well as, Montgomery County police and has provided expert witness services for clients in MD and DC. Mr. Grewell, in his time, was recognized as an Expert Witness for all aspects of both residential and commercial buildings and gave expert witness testimony in many courtrooms.
Ideally, we'd like to inspect your property-in-progress at three separate times during construction: Pre-backfill, Pre-drywall, and Final. It is not always possible to conduct all three inspections simply due to scheduling difficulties. The more notice you can give us of your needs, the better we are able to serve you.
Our most commonly requested inspection service is for a resale home. Older homes require a thorough inspection since many items begin to show wear and tear almost as soon as they are installed. Generally, the older the home, the longer it usually takes us to document its problems, however, some newer homes may have had numerous short-cuts taken during construction that will also require longer inspection/documentation periods.

Very pleased with the high-quality home inspection conducted by JD Grewell & Associates. Sean, the inspector, is a great professional who spent several hours inspecting my home. He did an outstanding job identifying potential maintenance issues and suggesting ways to address these. I am a homeowner who is not planning to sell any time soon, but nonetheless I wanted my home inspected by a qualified professional to know what issues, if any, exist that need to be tackled. Within 24 hours of
the inspection, Sean submitted a very detailed 58-page report, with pictures, listing items under categories

As buyers purchasing our first home, we wanted to make sure we chose a good home inspector so we know what we were getting ourselves into. We were VERY impressed by the time and care Sean put into the inspection. We had heard from friends and family their inspectors breeze through this process and I was so glad we cannot say the same. Every detail was noted and the report was extremely thorough. He let us ask as many questions as we needed and explained the entire process while he was doing the inspection. We will recommend him to every one and know we will be customers again if and when we need

He has done 4 inspections for me in the past 5 years, so you can see my dataset is not thin. I'm also an engineer and very savvy at home renovations, so I'm capable of making an assessment. Finally I did a fair about of pricing quotes and they were the lowest. This is the firm I use and recommend to all my friends.

When you love what you do, it shows. Mr. Grewell isn't the friendliest inspector, but his knowledge and expertise more than make up for it. He is extremely thorough and knows houses inside and out. If there is something going on in the house, you will know about it. He inspected my house and I was so impressed I joined him. I am thrilled to be helping people make one of, if not the biggest, financial decisions of their life. The price of an inspection is a drop in the bucket when you think about it, and the ammunition you get from one, used correctly, can more than offset the nominal fee.

J.D. helped us tremendously. I can't say enough great things about his service. We have a new home with many, many problems and his inspection really identified all the areas.

Any home buyer won't find a better home inspection company than JD Grewell & Associates(JDGAI), they are fantastic. We used them to inspect two homes we were considering for purchase. On the first occasion, JDGAI revealed multiple issues with the property that literally saved us from purchasing a home that would have cost tens of thousands to fix. Hugely helpful!!!!!! They were so meticulous, they found numerous things less professional inspectors would have likely overlooked.

We chose JDGAI because of their decades of experience and reputation for doing the best job possible. We were
