Turn a mold scare into a clear next step
Most sites either scare you or sell you. These four tools help you understand the mold you are dealing with, then decide what to do about it.
Identify
Is it actually mold, or just mildew?
Not every dark patch is mold, and not every mold is a crisis. The guided identifier walks you through color, texture, location, and moisture, then gives you a plain read on whether you are looking at mold, surface mildew, powdery efflorescence, or an old water stain.
What it turns out to be changes what you do next. A wipeable film on grout is a different problem from fuzzy growth creeping behind a baseboard, and the check points you to the right guide either way.
- Tells mold apart from mildew, efflorescence, and water stains
- Flags when a patch is likely past a safe do-it-yourself clean
- Sends you to the matching how-to for what you actually found

Assess
Know your home's real mold risk
Mold risk is mostly about where you live and how your home was built. Pick your city and Your Home Report pulls real climate normals, the typical construction era, and local flood exposure into one snapshot, then lists the government offices to call in your area.
It is the fast way to see whether your climate pushes mold risk up before a problem starts, and exactly who to reach locally if it already has.

Decide
Do you need a mold pro, or can you clean it yourself?
A small patch of surface mold in a dry spot is often a safe do-it-yourself job. Larger areas, hidden growth, and contaminated water are not. Four quick questions give you a clear read on which side of that line you are on, and the reasons behind it.
If it turns out to be a pro job, you will see what a licensed remediation contractor actually does and roughly what it costs, so none of the process catches you off guard.
- A plain DIY-or-pro verdict, with the why spelled out
- A realistic cost range for professional mold removal and remediation
- Safe step-by-step cleaning when it is a job you can handle
