Every town we cover in Frederick County
Frederick County is one of the areas we cover for home inspection, radon testing, mold testing and air quality testing. Lot size, drainage and the age of a home and its systems change from one address to the next, which is the whole reason an inspection is done on the house rather than on the neighborhood. This page is the index to the towns we cover here. Pick your town below for what we look for at that address and how to reach us there.

What we see in Frederick County homes
What an inspection turns on in Frederick County depends on the address rather than the county line. Where a property sits on public water and sewer, the visit is the standard structural and mechanical review. Where it runs on a private well and septic system, those components get their own look.
On an older house we check the electrical panel and service, roof age and layers, and any addition or finished space that may or may not have gone through permit review. On a newer one we still check grading, downspout discharge and any sign of moisture in a basement or crawlspace, because a house finished last year can be graded wrong just as easily as one finished decades ago. A failed well or septic system is a much bigger repair than most buyers expect going in, so where either is present we check it rather than mention it.
01
Well and septic systems
Where a property is not on public water and sewer, we check well flow and septic function separately from the main inspection. These systems fail in ways that do not show up on a simple walkthrough and cost real money to fix.
02
Additions and permit history
An older house has usually been added to or altered at some point. We look for work that does not match the original framing or wiring, and flag anything that appears to have skipped a permit, since that affects both safety and resale.
03
Grading and drainage on sloped lots
Where a lot slopes, water management matters more. We check grading, downspout discharge and crawlspace or basement moisture on every visit, since poor drainage is one of the most common findings on any inspection.
Most additions, decks and electrical work need a county permit.
When we inspect a home with an addition, a converted garage or a finished basement, we look for signs that the work was permitted and finaled, since unpermitted work is common in older housing and does not always meet current code. We note anything that looks unpermitted so a buyer can follow it up with the right office before closing.
Permit rules change, so confirm with Frederick County before you rely on this.
