Since 1993, Reliable Home Inspection Service has been proudly serving homeowners across Delaware—and into nearby communities in Pennsylvania and Maryland. We’re not a distant franchise or automated call center: every member of our team lives right here in the neighborhoods we inspect. From our ASHI-certified home inspectors to our DEP-licensed radon technicians and friendly office coordinators, these are your neighbors—people who share your schools, your streets, and yes, your weather challenges. They’re intimately familiar with the quirks of local construction, whether it’s identifying moisture-related wood rot in coastal Sussex County or spotting improper flashing on town-home roofs in northern New Castle.
When you call Reliable, you’re greeted by a knowledgeable professional who’s been trained in all aspects of home safety and performance. No robotic menu. No faceless customer service rep. Instead, you’ll talk with someone who can answer your questions in plain language, explain what to expect during the inspection, and—if you choose—schedule follow-up services like radon testing or post-repair re-inspections. Our inspectors know exactly how radon tends to accumulate in Pennsylvania basements, how certain neighborhoods in Newark have known structural issues, and what newer builders in Wilmington commonly miss during framing. That level of local insight, combined with more than three decades of hands-on experience, means you’ll get a thorough, photo-illustrated report—usually delivered the same day—that highlights every safety concern and maintenance recommendation specific to your home.
By choosing Reliable Home Inspection Service, you’ll work with a team that cares deeply about your home because, chances are, one of our own families lives just down the street.
Every inspection we conduct is more than just a checklist—it's a commitment to ensuring your peace of mind. We understand that buying or maintaining a home is one of the most significant investments you'll make, and our goal is to equip you with the knowledge to protect it. Our reports are not only comprehensive but also easy to understand, filled with clear photos and detailed notes that demystify the condition of your property.
We pride ourselves on fostering transparent communication. Whether you’re a first-time homebuyer or a seasoned homeowner, we encourage you to attend the inspection and ask questions. Our inspectors are always eager to share their insights and offer tips on how to maintain the safety and efficiency of your home.
With Reliable Home Inspection Service, you’re not just hiring an inspector—you’re gaining a partner in home care. Trust us to provide the honesty, expertise, and neighborly service that has built our reputation over the past 30 years.

WHY CHOOSE A RELIABLE HOME INSPECTION?
-
We cover the mechanical systems of the home including your HVAC unit as well as the structural condition including your foundation basement, crawl space and attic. All general interiors are inspected including the ceilings, walls, floors, doors and windows.
-
Plumbing and electrical systems are also inspected including piping, the water heater and the fireplace and chimney if present.
-
We perform an extensive inspection of the exterior of your home and roof which other companies may not. We inspect the siding, drainage, grading, gutters and roofing. All inspectors carry 32 foot ladders to inspect and walk the roof.
-
We cover multiple stages of new construction, residential and commercial buildings!
-
We carry many ladders, not just one or none. If we can safely evaluate your roof by walking it, we walk the roof. Not every inspection company gets in the crawl space or even has tall enough ladders to get on the roof. Other companies don't even walk on the roof or will just shine a light in the crawl space. If you call around to other companies for pricing, ask if they get in the crawl space and on the roof.
-
Same day delivery of your written, photographed home inspection report.
-
Three decades of experience and more than 20,000 completed inspections!
-
An unbiased opinion of the home. We work for you!
