  • Uses state-of-the-art detection equipment
  • Comprehensive reports for mold remediation
  • Can also perform post-remediation inspections


  • Difficult to reach during busy hours
  • Doesn’t offer mold remediation services

We like Mold Inspection Sciences of Houston because they use state-of-the-art equipment to detect mold and moisture on commercial and residential properties. 

After their visual inspection, the company will use air quality and humidity sensors like hygrometers and Zefon BioPumps to determine the extent of mold infestation in an area.

Then, the company will provide a systematic written report that details the extent of the mold coverage, the mold species present, and the airborne spore count. The report also contains photographs and recommendations, which can be used in mold remediation.

A detailed mold inspection report ensures that the remediation services won’t miss a spot, which can result in the resurgence of the infestation after some time. It also tells the technician what type of fungicide to use to effectively kill the mold.

After the mold remediation process in the area, we like that Mold Inspection Sciences of Houston will also come back to perform an inspection to ensure that the procedure is successful.

Although, note that this company is hard to reach during busy hours, especially when it comes to further questions after their inspection.

Furthermore, customers must also look for a separate company to address the mold problem because this mold inspection firm doesn’t provide removal and remediation services. 

They do this because, under Texas mold laws, an inspection company cannot perform remediation services because of a conflict of interest.

Still, we commend that, Mold Inspection Sciences of Houston also offers other test services aside from mold, including those to detect dangerous airborne substances like allergens, asbestos, for

  • Uses different sample collection methods to identify mold species
  • Has an in-house lab to process mold samples


  • Reports take a long time to arrive
  • Testing service more costly than average

AWA Environmental shines through its mold lab tests using air, bulk, and surface sampling.

We’re impressed with how the company’s technicians use different collection mediums like cassettes, culture dish collectors, and impaction samplers to get a sample of the mold. 

What’s more, they’ll also use swab tape if there is visible mold growth on surfaces like walls and duct linings.

Now, in cases of widespread growth, the company will even take a bulk sample from easily-removable materials like carpets and rocks. We like how technicians will work as lightly as possible and also carry air-tight sample containers to prevent cross-contamination.

The said samples acquired through the three methods will be sent to their in-house labs for analysis. After that, they’ll report on the mold species and develop customized plans to eradicate it from the building.

Now, one should know that different mold species have different effects on people. For example, the common Penicillium mold used in antibiotic agents can spoil food such as bread and cause respiratory irritation.

Although the company is thorough with their test, they are slow when it comes to providing a complete report to clients. Their testing can also cost more than $500, which is higher than the average mold inspection rates in Houston.

Still, the slow reports and higher fees are justified because AWA Environmental personally tests the samples in their lab, which needs a lot of time and money to accomplish.

  • Focuses on inspecting for mold after water damage
  • Assessment results arrive quick
  • Attentive inspectors


  • Doesn’t have their laboratory for testing
  • Fewer inclusions on their inspection compared to others

Certified Mold Testing and Consulting focuses on inspecting for mold after water damages in buildings. And we have to say, we’re quite impressed with their attention to detail. 

After events like bursting pipes or storms, the company will inspect areas with little sunlight like cupboards and under the sink to check if there’s still leftover water. Then they’ll check for airborne spores in the said areas to gauge the severity of mold growth.

One should know that fungi like molds and mildew thrive in dark and damp places. Water damage caused by flooding or pipe damage will provide a suitable environment for mold to multiply rapidly.

The samples will then be sent to laboratories for analysis. Customers commend how fast these results arrive, arriving only a few days after the technicians’ inspection.

Regarding their analysis, it’s important to note that the company has no in-house laboratory for analysis. This means that you may need to pay extra on top of their service fees.

The company also has fewer inclusions on its testing service compared to others. Nevertheless, customers love how attentive Certified Mold Testing and Consulting’s crew is during their inspections. 

The technicians will take their time to explain the inspection procedure and break down the contents of the report so that clients know what to expect when another company performs mold removal on their property.

  • Excels in inspecting commercial establishments
  • Reports arrive quick
  • Uses simple terms to break down issues to customers


  • Difficult to contact through their online channels
  • Shorter office hours than others

What makes Mold Inspection Houston stand out from others is its Commercial Mold Inspection offering.

The company’s process is quite impressive. It involves a visual inspection and air samples to test areas like storage rooms, above ceilings, and restrooms, which are the most common areas for mold growth.

We especially like that the inspectors assure that their work won’t disturb the operations of your businesses, as they will work outside business hours for lesser interruptions.

After they perform the mold removal, Mold Inspection Houston will return to conduct a post-remediation assessment and provide a Certificate of Mold Damage Remediation right after the inspection.

It’s important to know that a Certificate of Mold Damage Remediation, is a requirement in Texas for a successful insurance claim. We praise how quickly the company provides the document, as it enables customers to process their insurance documents faster.

Although, it’s difficult to book the services of this company, they reply slowly to messages sent to their different online platforms. The company also has shorter office hours than others, inconvenient for those that need their services during the weekend.

In addition, clients also praise the quickness of the inspection results’ arrival. Within only a maximum of 2 days, the property owner will receive the written report through their physical and electronic inboxes.

Also, the reports are written in such a way that they use simple terms to easily break down information for clients. We think it’s noteworthy because most reports involve complex terms that may confuse a person with little knowledge of mold inspections.

  • Has 24-hour inspection services
  • Technicians arrive quick on appointments
  • Reports are sent within 24 hours after inspection.


  • Fewer services than other mold inspection companies
  • Follow-up consultations take a few days to schedule

Mold Testing Houston provides the usual mold inspection services like others. However, what sets the company apart is its 24-hour inspection services.

We like how the company’s process starts with a visual inspection of every nook and cranny of the house. The technicians mark the areas affected with mold to warn customers to avoid these places.

After that, the company will take samples using the air, bulk, swab, and tape methods. Technicians would also analyze the air both inside and outside.

We were impressed that mold inspectors also measure air quality outside as a point of reference for normal air composition. The results will be compared to the inside levels to see if the air quality inside is at acceptable levels.

The praiseworthy aspect of this service is that the technicians can arrive even after midnight to check your house for mold. It’s perfect for those people who are working day jobs or are unavailable during weekdays.

In addition, the technicians arrive hours after you book their services. The reports also arrive within 24 hours of the inspection. 

For us, inspection companies must arrive and send test results quickly so that the mold remediation firms can start their work as soon as possible.

On the other hand, Mold Testing Houston has fewer services than other mold inspection companies. Also, their follow-up consultations take a few days to schedule, which lengthens the time before you can avail mold remediation.
