Keystone Home Inspections

Giving You our Absolute Best

About Us

As a young growing family with two children, trying to purchase our first home was incredibly stressful. The last thing that we wanted to worry about was the home of our dreams needing a costly major repair upon moving in. We were much more concerned about which shade of pink our daughter loved more and which couch layout would work best—all of the fun stuff!

Thankfully, we had a home inspector to trust and put us at ease. Our skilled home inspector inspired me to start my own business to offer everyone that same level of comfort and trust. As a couple who has been married for 7 years with two children, we understand the stress and difficulty you face during the home purchasing process. Let us take the weight of one of those stresses off of your shoulders!

About the Inspector

My name is Johnnie Sexton and I am the owner and operator of Keystone Home Inspections. When you hire me, you can trust that you’re getting the right man for the job. I have over a decade of experience in the construction industry and seven years in the plumbing field. These years of experience, especially the years I spent as a service plumber, have trained me to have a keen eye for detail.

I use my eye for detail to find problems in your home before they become headaches. I have been trained by one of the nation’s top training institutes and am a Certified Professional Inspector with InterNACHI.

The Keystone Promise

Choosing the right home inspector can be difficult. Unlike most professionals, you don’t typically meet your inspector until the appointment itself—after the hiring process has already been completed. Every home inspector has different qualifications, equipment, experience, reporting methods and pricing. A thorough inspection depends on the individual inspector themselves. If you hire Keystone Home Inspections to inspect your home, we guarantee that we will give you our absolute best effort.


At Keystone Home Inspections, a standard home inspection is anything but standard! Our skilled inspectors will act as your eyes, ears and hands while carefully inspecting every portion of your home or the home you are interested in purchasing.

Pre-Purchase or Home Buyers Inspection

A home buyer’s inspection will let you and a professional inspector go through the home that you want to purchase with a fine-tooth comb. Our inspector will examine everything from the plumbing to the HVAC system. Our inspectors always offer an unbiased opinion on the condition of the home or make any personal gains. Our goal is to have every prospective home buyer fully understand any potential issues that exist within the home they want to buy.

Pre-Listing or Home Seller’s Inspection

If you are preparing to sell your home, a thorough home inspection beforehand will allow you to correct any issues before they detract from the value of your home! Our home inspectors will walk through your home and identify any potential problems and potential solutions. A pre-listing inspection allows you to find out issues, use your preferred contractor and shop around before it is an urgent problem. Pre-listing inspections are the best way to get the highest amount your home is worth from home buyers.

Maintenance Inspection

Even homes in the best condition start to degrade over time. Whether you’re living in a home that used to be new 20 years ago or starting to have issues with a 100+ year old home, a maintenance inspection will identify problems you wouldn’t otherwise notice. As your home ages, all of the systems within it age as well. Our maintenance inspection encompasses all of your home, from the basement to the attic, to identify hidden problems before they become a major pain.

Additional Services

Keystone Home Inspections offers additional services that include:

Radon Inspection

Radon is a tasteless and odorless gas that is one of the primary causes of lung cancer in the United States. Radon is formed by decaying rock that seeps into plumbing, basements, and sump pump pits. Testing for the gas is critical, especially if you are in an older home. Our radon tests will be left in your basement for 48 hours while you live and use your plumbing normally. We will pick up your test, orchestrate the testing process and give you the results.

Pool or Spa Inspection

A new home with a swimming pool or spa can cause a lot of heartache if it is in poor condition. Our pool or spa inspection services will carefully examine the pool to detect any signs of improper maintenance or damage. We will ensure that your pool meets the standards set by bother InterNACHI and ASHI.

Water Quality Testing

Many homeowners need their well water tested before moving in or applying for certain loans. While wells are intimidating if you’ve never used one before as your primary water source, our water quality testing can offer you peace of mind. We will walk you through the process and test your water for 90+ different issues including heavy metals and bacteria.

Baltimore County Rental Inspection

Baltimore County law requires rental property inspections on a regular basis. We are equipped to perform these county-regulated inspections.
