What We Do?
Typically, a MACTexas mold assessment will consist of:
I. A Top to Bottom Visual Inspection
- Interior & exterior conducive condition areas
- Thermal Imaging Infrared Scan
- Humidity Level check
- Carbon Dioxide(CO2) check
II. Collecting of Samples for Testing
- A bulk, swab, or tape surface sample (as needed)
- A min. of (2) Air quality tests indoor & outdoor (as needed)
- A mold lab test (if applicable)
- Remediation protocol (if applicable)
- Corrective action / Remediation (if applicable)
MACTexas will visually ‘assess’ your residential building, commercial building, municipal building, school, church, or industrial building. We will take a sample of the air, the surface, or both. Essentially, a mold inspector collects the air or surface samples and delivers them to the lab to determine what kind of mold exists and/or if the mold found can grow in the area tested.
We provide a detailed written ‘mold’ assessment of the findings afterward. Contact us today in Houston, Texas to schedule a service or request a free quote. Every MACTexas mold assessment comes with a courtesy (RH) Relative Humidity level reading as well as a (CO2) Carbon Dioxide level reading.
*We do not perform mold remediation, which eliminates any conflicts of interest.*
Whether you need to gather data for a mold litigation case, have potential health concerns due to mold, or looking for peace of mind, the MACTexas is ready to provide the knowledge and hands-on experience you’ll need to get the job done. The process for a cleaner, healthier and mold-free home starts with these simple steps:
Step 1: Set an Appointment at your Convenience
The first step is to set an appointment at your convenience to have a state-licensed and insured mold inspector come to your location. Appointments can be made from Monday through Saturday at a time that works best for you. Just fill out the form or call us to speak with one of our friendly experts!
Step 2: The Visual Mold Test
The entire mold test inspection is a two-step process where the inspector will perform a visual mold inspection as well as a collection of samples. The entire mold test process can take up to 1.5 hours.
Visual Mold Inspection:
Our state-licensed and insured Mold Assessment Consultants will begin the process with a thorough Multi-Point Inspection. An exterior inspection of the property will be conducted to look for potential microbial growth, unusual humidity levels, and water intrusion. The interior inspection will include a visual check for mold, humidity, and temperature readings of each room, and inspection of your HVAC system. Based on the results of the visual mold inspection recommendations will be made for the sampling process.
Collection of Mold Test Samples:
The second part of the mold test is the collection of samples. An interior air quality sample will be taken as well as an exterior air quality sample for comparison. As an added bonus, MACTexas performs a swab sample of the HVAC system to provide additional insight into the interior air quality. Additional samples can be taken at the discretion of our certified inspector or at your request.
Step 3: Lab Testing
Once the mold test is completed, the biological samples are overnighted to a third party Certified Microbiology Laboratory under Chain of Custody. Once the environmental samples are received and properly logged into the laboratory, analysis begins. The results of the mold test samples will usually be available between 3-7 business days with the option to expedite your results.
Step 4: Discuss Lab Results with a Senior Mold Assessment Consultant
The last step in the process is our consultation call. Once the lab results have been returned, a Senior Mold Assessment Consultant will contact you to discuss any results that need your attention, including any potential follow-up steps and assistance in mold remediation, litigation, or even find a health care provider. You will also receive a certified test report with all the findings of the mold test.
What is Included With Our Mold Inspection
Our base service includes:
- Interior and exterior inspection of the structure including attic and HVAC systems
- Exterior baseline testing
- Relative humidity readings
- Examination of the HVAC system, including swab sample
- Interior and exterior temperature readings
- Moisture readings in the walls, floors, and ceiling – where applicable
- Two microbiology samples (Air-O-Cell)
- Certified microbiology laboratory results
- Final written report with our recommendations and opinions
Air samples can be used to gather data about mold spores present in the interior of a house. These samples are taken by using a pump that forces air through a collection device which catches mold spores. The sample is then sent off to a laboratory to be analyzed.
TAPE LIFT, BULK AND SWAB SAMPLING, ARE TECHNIQUES USED FOR DIRECT EXAMINATION. A DIRECT EXAM ALLOWS FOR THE IMMEDIATE DETERMINATION OF THE PRESENCE OF FUNGAL SPORES AS WELL AS WHAT TYPES OF FUNGI ARE PRESENT. DIRECT EXAMINATIONS SHOULD ONLY BE USED TO SAMPLE VISIBLE MOLD GROWTH IN A CONTAMINATED AREA SINCE MOST. MOST SURFACES COLLECT A MIXTURE OF FUNGAL SPORES THAT ARE NORMALLY PRESENT IN THE ENVIRONMENT.
THERMAL IMAGING INFRARED SCAN
ONE METHOD THAT CAN BE USED TO DETECT MOLD IN A HOUSE IS BY USING INFRARED THERMOGRAPHY. BY USING AN INFRARED CAMERA THAT PRODUCES IMAGES OF HEAT RADIATION, A TECHNICIAN CAN DETECT THE EXISTENCE OF MOISTURE INSIDE OF WALLS THAT CANNOT BE SEEN BY THE HUMAN EYE. MOISTURE AND SIMILAR CONDITIONS CAN PROMOTE MOLD GROWTH
Humidity Level Reading
Humidity levels above 55 percent can allow mould to grow, although levels of 70 percent are more ideal for mould growth.
Sometimes, humidity or dampness (water vapor) in the air can supply enough moisture for mold growth. Indoor relative humidity (RH) should be kept below 60 percent — ideally between 30 percent and 50 percent, if possible. Low humidity may also discourage pests (such as cockroaches) and dust mites. Over 50 percent there is enough moisture for mold growth.
Carbon Dioxide CO2 Level Reading
When mold increases in your environment and body, it creates an abundance of carbon dioxide and when mixed with water and blood, it turns into carbonic acid. This CO2 then causes your cells to be deprived of oxygen and the blood to become acidic.
Indoor carbon dioxide concentrations are driven by a combination of outdoor CO2, indoor breathing and the ventilation rate of the building. As buildings and homes become more energy-efficient and airtight, this means we have less fresh air. Many of the ventilation systems we use today recycle air to conserve energy, essentially moving the contaminated air around rather than cycling in new air. This results in high CO2 concentrations and poor indoor air quality.
