Mold inspection across Northwest Washington.

You may have a musty room, a recurring stain or a concern raised during a home inspection. An inspection provides a place to start when you need to understand the property conditions and decide what further work makes sense. Tell us whether your goal is to investigate an unfamiliar problem, follow up on a known leak or plan work in an affected space.

Bring any earlier findings into the conversation. An old test result, a repair invoice or photos taken before a wall was closed can help explain what has already been investigated and which questions remain.

The investigation considers visible conditions and moisture clues together. Damp materials, repeated condensation and the history of a leak can help direct attention to an area. Moisture meters can support that investigation by measuring building materials; the readings still need to be interpreted in context.

North Sound also uses infrared imaging. A thermal camera shows surface temperature differences, not mold or moisture itself. It can point to an area worth checking with other tools. Learn more about the equipment on our Tools of the Trade page.

Mold is not always on the face of a wall. EPA guidance identifies concealed locations such as the back of drywall, carpet backing, damp crawlspaces and roof materials above ceilings. The areas included in your inspection depend on the concern, access and the agreed scope.

Tell us if an attic, crawlspace or enclosed wall is part of the concern before the visit. Investigation that disturbs suspect materials needs care because it can spread debris and mold. Discuss access and any proposed opening of materials with the inspector first.

Make a short list of the rooms or surfaces that concern you and describe what changes over time. Does the stain return after rain? Was a leak repaired, but the odor remained? Those observations are useful even if you do not know the cause.

For a rental or commercial property, identify the person who can authorize access and share maintenance history. Before scheduling, ask which spaces are included, what access is needed and how the findings will be communicated. Discuss deadlines at the first call so the scope and timing can be considered together.

The practical question is what to do with the information. Your next conversation may be about moisture control, a repair, targeted laboratory sampling or a remediation scope. Ask which observations support each recommendation and whether any inaccessible areas leave unanswered questions.

Inspection and testing have different purposes. If sampling is proposed, ask what it would clarify and how the result could affect the plan. Our testing page explains the difference between air and surface samples and the limits of a laboratory result.
