Air Testing

Same-day and next-day appointments are usually available across our Tacoma service area, with 24/7 emergency response for active leaks, recent water damage, or urgent real estate timelines. Standard scheduling runs 1 to 3 business days depending on availability.

Our certified mold inspectors assess bathrooms, kitchens, laundry rooms, basements, attics, crawl spaces, HVAC components, and any area showing signs of past or current water issues. Thermal imaging and moisture meters identify hidden moisture behind walls and under floors.

Yes, in most cases. Tacoma's historic homes — particularly those built before 1950 in the North End, Stadium District, and Hilltop neighborhoods — carry elevated mold risk for several interconnected reasons. Original wood framing has been absorbing and releasing moisture for decades, and areas where small leaks or condensation were never properly addressed have often developed long-term mold colonies behind plaster walls and under hardwood floors. Single-pane windows generate significant condensation during Tacoma's wet winters, feeding moisture into adjacent wall assemblies. And many of these homes retain original or modified crawl spaces where vapor management was never a design priority. That said, newer construction is not immune — tightly sealed modern homes in Tacoma's south end can trap interior moisture if ventilation is inadequate, and HVAC condensation issues are common in newer builds throughout the region.

Pricing varies based on the size of the property, the scope of testing required, and whether any lab work is included. Most residential mold inspections in Tacoma fall within the standard industry range of $300 to $600, with a clear quote provided before any work begins.

Air sampling, swab testing, tape lift testing, wall cavity sampling, and HVAC mold testing. The inspector recommends the right method on-site based on what's found. Samples go to a state-certified lab, with results typically back in 24 to 72 hours.

Mold needs water to grow, so finding the moisture source is what prevents the same problem from coming back after any cleanup. Moisture detection during the inspection identifies plumbing leaks, roof leaks, condensation issues, and humidity buildup that's feeding any growth.

Yes. Post-remediation verification confirms the remediation contractor's work succeeded and the space is safe to reoccupy. Because we don't perform remediation ourselves, the verification stays independent of the remediation contractor's interests, which is what insurers and tenants look for.

Inspection and testing only. In Tacoma's older housing stock, where a moisture source is often a building-system failure — aging plumbing, deteriorated crawl space vapor barrier, failed roofing detail — rather than a single acute event, the remediation scope can be substantial, and a company with cleanup work to sell has a financial reason to find more of it. What you receive is the diagnosis: extent of growth, moisture source, lab-confirmed species, and a written scope you can use to get comparable bids from multiple contractors. Because we perform no remediation, our post-remediation verification carries no conflict of interest — in Tacoma's older rental and commercial stock, that independence is what makes the clearance report credible to an insurer or a landlord.

Post-remediation verification confirms that a remediation contractor's work succeeded — growth was removed, the moisture source was controlled, and spore counts are back within normal range. It's needed whenever a remediation was performed and the property owner, buyer, insurer, or tenant requires independent confirmation that the work is complete and effective. In Tacoma, it's particularly relevant for properties near the waterfront and port corridor where persistent ground moisture means a remediation that didn't address the source will return within a season. Because 24H Mold Inspection never performs the remediation work, the verification is independent — we have no stake in the outcome.

A standard single-family home inspection takes two to three hours depending on the size of the property and how many areas of concern the initial walkthrough identifies. Crawl space access in older Tacoma homes adds time — the subfloor inspection is thorough rather than a quick visual. Commercial properties, multifamily buildings, and properties near the waterfront with below-grade spaces take longer. The written report with lab results is typically delivered within three to five business days of the inspection. Same-day and next-day appointments are usually available, and 24/7 emergency response is available for active water intrusion.

Yes — property managers and landlords are a significant part of our Tacoma work, particularly in the Hilltop and South End rental corridors where older housing stock and high occupancy create recurring moisture conditions. What we provide is documentation: a written, lab-verified report that establishes the condition of a unit at a specific point in time, identifies the moisture source, and defines what remediation is needed. For a landlord responding to a tenant habitability complaint, that documentation either confirms the problem and defines the fix or provides defensible evidence that the unit met habitability standards at the time of inspection. Because we perform no remediation, the report has no financial interest attached to its findings.

Yes — pre-purchase and pre-listing inspections are a common request in Tacoma's North End and Stadium District, where older properties change hands frequently and buyers want independent assessment of moisture conditions before closing. The report documents thermal imaging findings, moisture meter readings, crawl space condition, and lab results in a format that a buyer's agent, lender, or escrow company can work with. We operate independently of any remediation company, which means our findings aren't shaped by a financial interest in the cleanup work. Turnaround is typically two to three business days from inspection to written report.
