What Really Happens During a Home Inspection

If you have never been through a home inspection, the whole thing can feel like a black box. You hand over a check, someone walks around your future home with a flashlight, and a day later a long PDF lands in your inbox. I want to pull back the curtain a little, because an inspection you understand is worth far more than one you just file away.

I am Joshua Knouff. I spent more than 25 years working with homes and buildings, including years as a union carpenter framing and finishing houses, before I became a licensed Washington State home inspector. Here is how I approach inspection day across Pierce and Kitsap counties.

What I am actually doing out there

A home inspection is a thorough, visual evaluation of the accessible parts of a house. I am not tearing open walls or moving your seller's furniture. I am looking, testing, and documenting the things that affect safety, cost, and how the home will hold up over time.

On a typical inspection I work through:

  • The roof and gutters, including how water is meant to leave the property
  • The exterior, siding, trim, decks, grading, and drainage
  • The foundation and structure, the bones of the house
  • The attic, insulation, and ventilation
  • The electrical panel and visible wiring
  • Plumbing and water heating, including drains and venting
  • Heating and cooling, weather permitting
  • Windows, doors, and the interior
  • Built-in appliances, a basic functionality check

My carpentry background matters most here. Because I have built these systems with my own hands, I know where corners get cut and what a small stain or a hairline crack is actually telling me.

How long it takes

Most inspections take two to three hours, depending on the size and age of the home. New construction can go faster. A 1920s farmhouse with three additions takes longer, and that is fine. I would rather spend the extra hour than miss something that costs you thousands later.

You are welcome to come along. In fact, I encourage it. Walking the home together is the best way to understand your report before you ever open it.

Reading your report without the panic

Here is the part nobody tells first-time buyers: every house has findings. A clean report does not exist, and if someone hands you one, be skeptical. My job is not to scare you or to talk you out of a home. It is to give you the truth so you can make a confident decision.

When you read your report, sort the findings into three buckets:

  1. Safety and major systems, the things worth negotiating or addressing before you close
  2. Maintenance items, normal upkeep you will handle over time
  3. Minor and cosmetic notes, good to know, rarely deal-breakers

If you are ever unsure which bucket something belongs in, call me. Clear communication is the whole point. I will never just hand you a document and disappear.

The bottom line

A good inspection turns a stressful unknown into a plan. You walk away knowing what you are buying, what to budget for, and what to keep an eye on. That peace of mind is exactly what every homeowner deserves.

If you are buying in Tacoma, Gig Harbor, Port Orchard, or anywhere across the South Sound, I would be glad to walk the home with you.
