A clearer place to begin.

We organize common home conditions around the questions homeowners actually have: what am I looking at, who normally handles this, and what would make me change course?

Common Course provides general educational information. It does not inspect your property, diagnose a condition, prescribe a repair, or replace the judgment of a qualified professional who can evaluate the property directly.

Start with the condition that sounds most like what you’re seeing. The default course identifies a professional category that commonly evaluates that kind of condition. “Change course if” highlights observable circumstances that may make another category relevant.

What you observe is useful information for a professional. It is not a diagnosis.

Some pages may offer a link to connect with a professional or a third-party service that helps locate professionals. If you use one of these links, Common Course may receive compensation. That compensation does not determine which professional categories appear in our guidance.

Any professional or matching service you contact is independent from Common Course. Availability, qualifications, licensing, pricing, scope, and suitability should be evaluated for your particular project and location.

Where appropriate, condition pages include references to technical, government, standards, trade, or other relevant publishers used for general orientation. Sources support the educational material; they do not turn a web page into an evaluation of a particular property.
