Home Inspectors Who Know Oswego Inside & Out

Oswego has transformed dramatically over the past two decades. Once a small Kendall County farm town, it's now a thriving suburb of over 35,000 residents with a booming real estate market, top-rated schools under Oswego CUSD 308, and one of the most active new construction markets in the southwest suburbs.

With so much newer construction in Oswego, many buyers assume a brand-new home doesn't need an inspection. That assumption is one of the most costly mistakes we see. New construction homes in Oswego regularly have issues with grading and drainage, improperly installed windows and flashing, HVAC ductwork inconsistencies, and minor structural defects that are far cheaper to address before closing than after. Our inspectors have extensive new construction experience and know exactly where builders cut corners.

Oswego also sits in Kendall County, where radon levels are well above the national average. We strongly recommend pairing every home inspection in Oswego with a certified radon test.

We also serve buyers in nearby Yorkville, Plainfield, Montgomery, Aurora, and Naperville.
