Bruce Wall is a small reference site about the most overlooked part of a house: its walls. Walls hide almost everything that matters — framing, insulation, wiring, moisture — behind a quarter inch of paint, so when something goes wrong the first problem is usually just figuring out what you are looking at.
The guides here answer specific questions homeowners actually ask: how to patch a drywall hole so it disappears, why a wall feels damp and how to narrow down where the water is coming from, how wall insulation is actually specified, and what the federal renovation rules mean if your painted walls date from before 1978. Where a federal agency or industry body has published the authoritative document on a topic, we link straight to it rather than paraphrasing it badly.
The centerpiece is the Drywall Repair Cost Estimator, a quick tool for getting a defensible ballpark before you call anyone. It won't replace a quote — nothing on a website can — but it will tell you whether the number a contractor gives you is in the neighborhood of normal, and it's honest about what it doesn't account for.
Everything here is reference material written for a general U.S. audience. For decisions involving lead paint, mold remediation, or structural problems, the guides point you to the right certified professional rather than pretending a web page can stand in for one.
