Mold Inspection & Testing in Houston, TX

Mold Inspection & Testing in Houston, TX

Mold inspection and testing in Houston typically runs between $300 and $700 for a standard whole-home assessment, with most homeowners paying around $450 when the inspection includes air sampling and a written lab report. Keegan Restoration Houston inspects, samples, and documents mold conditions across the Houston metro, then hands you a plain-language report that tells you exactly what we found, where it is, and what it will take to fix it. If you’re seeing stains, smelling something musty, or dealing with repeat allergy symptoms inside your home, call (325) 550-1783 and we’ll walk you through what an inspection covers before you spend a dollar.

This service sits under our broader Mold Remediation in Houston work. The distinction matters: inspection is the diagnostic step. Remediation is the fix. Some companies blur the two because they want to sell you a treatment you may not need. We keep them separate on purpose. You get an honest assessment first, and a written price only if work is actually required.

When You Need Mold Inspection & Testing

Houston’s humidity doesn’t let up. A home that stays above 60 percent relative humidity for any stretch of time is a candidate for hidden mold, even when no leak has ever been obvious. Here are the situations where we most often recommend an inspection:

• You smell it but can’t see it. A persistent musty or earthy smell, especially in older Houston neighborhoods like Braeswood Place or Garden Oaks, often points to mold behind drywall, under carpet, or inside HVAC duct runs.
• You had a water event and dried it yourself. A supply-line leak, a dishwasher overflow, or a slow AC drain pan leak that lingered for more than 48 hours is a textbook mold trigger. Even if the surface feels dry to the touch, the cavity behind it may not be.
• Family members feel better when they leave the house. Chronic congestion, headaches, coughing, or worsened asthma that eases at work or school but returns at home is a common reason Houston homeowners call us.
• You’re buying or selling a home. A mold inspection before closing gives both parties a documented baseline. In Houston’s market, that report can protect a buyer from inheriting a hidden problem and protect a seller from a post-close dispute.
• You’re moving back into a home after a major flood. After Harvey or any of Houston’s subsequent flood events, structural cavities can hold moisture for weeks. An inspection before rebuilding starts tells you what the framing actually absorbed.
• You see staining that keeps coming back. If you’ve cleaned a patch of discoloration on a ceiling or baseboard and it returned within months, the moisture source driving it is still active – and the visible stain is rarely the full extent of it.

None of these scenarios mean you definitely have a mold problem. They mean you need someone to look properly. That’s what we do. The inspection is the part of the job where we find out what’s actually going on, and we document every finding so you’re not relying on a verbal summary.

Our Mold Inspection & Testing Process

Here’s how a Keegan Restoration Houston inspection runs, start to finish, when you bring us into a Houston home:

1. Walk-through and moisture mapping. We start with a full property walk, inside and out. We look for water intrusion points – roof flashing, window seals, slab edges, AC condensate lines – then use moisture meters to map elevated readings in walls, ceilings, and floors. In Houston homes, the attic and the AC closet are two areas we never skip because heat and humidity concentrate there.
2. Visual inspection of suspect areas. Every area with elevated moisture gets a close visual check. We look behind furniture against exterior walls, inside cabinets under sinks, around toilet flanges, and at baseboards near tubs and showers. This is where the trade experience matters – mold in Houston hides in predictable places, and we know what those look like.
3. Sampling strategy, agreed in advance. Before we pull any sample, we tell you what we’re sampling, why, and what each sample costs. Air samples are taken with a calibrated pump and cassettes, typically one outdoor baseline sample and one per suspect room. Surface samples use sterile swabs or tape lifts. You approve the scope before we start – the price never changes mid-job.
4. Third-party lab analysis. Samples go to an independent accredited lab for analysis. We do not run samples through an in-house lab, and we do not interpret results with an interest in finding mold that isn’t there. The lab reports genus-level identification and spore counts, which gives you an objective read on what’s in the air.
5. Written report and plain-language review. You get a written report that maps every finding: what was tested, where, what the lab found, what the moisture readings showed, and whether remediation is recommended or not. Then we sit down or get on the phone and walk you through it in plain English, page by page, until you understand every line.

This process runs to The Garrison Standard, which is the operating discipline Keegan Restoration Houston has followed since joining the Garrison Partners family in 2005. Show up inside the window, put the price in writing before work starts, do the work by the book, leave the site clean, and stand behind it for a full year. That applies to every inspection we run, not just the big remediation jobs.

Mold Inspection & Testing Pricing in Houston

Straight numbers, because you should know what you’re walking into before you pick up the phone. Here’s How Much Does Mold Remediation Cost? (2026 Price Guide) - Houston, TX alongside what mold inspection and testing in Houston generally costs at Keegan Restoration Houston:

• Visual inspection only: $150 – $300. We do a full moisture mapping and visual assessment, then give you a verbal summary and written notes on what we found. No lab samples.
• Visual inspection plus air sampling: $350 – $600 for a typical 2,000 – 3,000 square foot Houston home. This includes one outdoor control sample and two to five indoor samples, lab fees, and a written report with lab results.
• Whole-home inspection with air and surface sampling: $500 – $800 for larger homes, homes with multiple suspect areas, or situations where we need to isolate specific microbial growth for identification.
• Post-remediation clearance testing: $250 – $450, depending on sample count. If you’ve had remediation done elsewhere and need an independent third-party clearance read before you let the drywallers back in, this is the tool you want.

What moves the price: home square footage, the number of suspect areas, how many air samples you approve, and whether you need surface identification in addition to air sampling. What doesn’t move the price: anything that happens at the door. We quote a number, you approve it, we do the work at that number. No add-ons, no “while we’re in there” upcharges.

We also tell you straight when you don’t need testing. If we can see visible mold growth that clearly needs Mold Remediation services, an expensive lab panel may be money you don’t need to spend. The inspection is a diagnostic tool, not a revenue lever. When testing is warranted, we say so. When it’s not, we tell you that too.

What Houston’s Climate Means for Mold Inspection

Houston sits in a hot-humid climate zone where the outdoor dew point stays above 65°F for most of the year. That means condensation happens easily on interior surfaces, especially around AC supply vents, uninsulated ductwork, and poorly sealed windows. It also means that drying a wet wall cavity is not just about time – it’s about psychrometrics, which is the science of how temperature, humidity, and dew point interact to move moisture out of building materials.

We run XPOWER and B-Air air movers and dehumidifiers during the drying phases of any mold-related water event, and we operate in compliance with IICRC standards for water damage restoration and mold assessment. When a Houston home has a hidden mold issue, it’s almost always a moisture source that never fully dried. Our inspection protocol is built around finding that source, because you can scrub every visible spore off a wall and the colony will return if the moisture is still feeding it.

In practice, we see a lot of mold problems in Houston homes that trace back to one of three things: an AC drain line that backed up inside a wall, a slow plumbing leak that puddled under a cabinet for months, or a roof flashing detail that failed during a heavy spring storm. In neighborhoods like Timbergrove and Sharpstown, where the housing stock is older, we regularly find exterior wall cavities that have been wet for years with no visible indication from the living space. That’s the kind of thing a visual-only “inspection” misses, and it’s exactly why our process includes moisture mapping with professional equipment.

Why Houston Homeowners Call Keegan for Inspections

Shane Pruitt runs Keegan Restoration Houston, and the way he describes the inspection work is simple: “We’re there to give you an honest read, not to sell you a job.” That philosophy comes out of years of watching homeowners get deliberately spooked by inspection reports that overstate findings to justify a big remediation contract.

Here’s what actually sets us apart when you hire us for a mold inspection in Houston:

• The price is in writing before we start. You’ll get a scope and a number, in writing, before we pull the first sample. That number does not move. The Garrison Standard means exactly that – no door dickers, no surprise line items.
• We don’t self-refer. Keegan Restoration Houston does both inspection and mold remediation, which means we could, technically, inspect a house and immediately recommend ourselves for a five-figure remediation job. We don’t do that. The inspection department reports objectively. If remediation is needed and you hire us, good. If you take our report to another contractor, that’s fine too. The report stands on its own.
• Background-checked, uniformed technicians. Every Keegan technician who walks into your home has passed a background check and arrives in a company uniform. You know who’s in your house. That’s not a perk – it’s a baseline for letting a stranger into your home.
• A live person answers the phone. Calls to Keegan Restoration Houston are answered by a live person, 24 hours a day, 7 days a week. No phone tree, no call-back queue, no third-party answering service that can’t answer a basic question. If mold is actively spreading, you don’t have time to leave a voicemail and hope.
• Written documentation, formatted for your insurance claim. Every inspection we run produces written documentation that can be submitted to your insurance carrier. We format our reports to align with what insurers actually need, which saves you from going back and forth with an adjuster over missing details.

We’re part of the Garrison Partners family, and we’ve operated in the Houston market under that banner since 2005. The 365-Day Done Right Promise applies to our remediation work – every repair is backed by a written guarantee, and if it fails within one year, we return and make it right at no charge. For inspections, the equivalent commitment is this: if our report misses a mold condition that a reasonable professional inspection should have caught, we’ll come back and re-inspect at no charge.

FAQs – Mold Inspection & Testing

How much does mold inspection and testing cost in Houston?

Mold inspection and testing in Houston typically costs $300 to $700 at Keegan Restoration Houston, with visual-only inspections starting around $150 to $300 and full air-and-surface sampling packages running $500 to $800 for larger homes. The exact number depends on home size, how many rooms need sampling, and whether you need lab identification of specific mold types. Call (325) 550-1783 for a free estimate with the exact scope and price for your home.

How long does a mold inspection take?

Most mold inspections in Houston take 2 to 4 hours on site, depending on home size and how many rooms we’re sampling. Lab results typically come back within 3 to 5 business days, at which point we send your written report and walk you through the findings.

Do I need mold testing if I can already see mold?

Not always. If visible mold is clearly present and the moisture source is identified, the next step is remediation, not a lab panel. We’ll tell you honestly when testing is unnecessary and save you the money.

What’s the difference between mold inspection and mold remediation?

Inspection finds the problem and documents it. Mold Removal and remediation fixes the moisture source. Keegan Restoration Houston offers both services, but we keep them separate so your inspection report is never influenced by the possibility of selling you a remediation job.
