What Does A Mold Inspection Report Look Like
Deteriorated shingles or other roof coverings are one of the first things home buyers and home inspectors notice. If the elements underneath the shingles are moist or rotted, repairs will likely be requested. Some states require a separate roof inspection. Make sure flashing around the base of the chimney is watertight, and that mortar and bricks are in good condition. Inspect the fireplace to make sure it is functioning properly .
Many mold investigators also provide non-diagnostic mold screening surveys for real estate transactions and post-mold remediation (cleanup) project onsite inspection and clearance test reports. Other professional services include odor source detection, gas testing, and building condition of property and pre purchase inspections.
What inspection methods and testing techniques form the basis of your indoor air/mold investigation report? Mold cultures are unreliable for overall characterization of fungal contamination of indoor air. Home test kits, settlement plates, samplers which collect spores onto petri dishes, and sterile swabs all have a place in the arsenal of tools but not for overall building characterization.

In one class I attended a mold test lab supervisor showed me the cheat sheet she provides to her afternoon high-school aged employees who are trained to look through the microscope for one of the eight common mold species whose photograph appears on a colored card. An under-trained lab technician may be tempted to stop examining a sample as soon as s/he finds one of the important eight on the card.
Sometimes even the presence of a few spores can be significant if they are highly toxic, as they might indicate that a problem material is present or growing somewhere in the building. But a distinction should be made between what is obviously significant by visual inspection (or if necessary by actual quantitative measurement if it was an air sample), and what was found as present but not necessarily significant.

Attic mold often appears as a thin grey or black layer on the very top of the insulation. Â The dimensionality of the growth is difficult to determine, as the underlying insulation presents a rough and uneven surface. Â If the mold growth is due to high humidity and condensation, as is usually the case, the mold growth will only occur on top of the insulation. Â In the image below, notice how the mold growth uniformly covers the insulation, but is not found on the lower layers, which were disturbed during the inspection.
A mold test lab expert alone, knowing nothing about the building conditions, test conditions, or occupant sensitivities, has only a limited ability to interpret the lab findings. Waving your notebook at a surface or choosing not to wave it during mold sampling can make a thousand-fold difference in the mold score at the exact same location.

Mildew odors signal that a basement is too moist. Buyers and home inspectors will look closely at the walls and floors for patches of mildew and signs of dampness. The inspector might use a meter to determine how much moisture is present in these spaces because moisture deteriorates building materials and attracts insects. Cover exposed earth in basements and crawl spaces with plastic to help keep moisture levels down. Most foundation leaks are a result of poor drainage that funnels water towards the foundation. To address this issue, consider the following steps:

Software often gives inspectors the choice of including photographs in the main body of the report, near the narrative that describes them, or photographs may be grouped together toward the beginning or end of the report.

NAMRI Standards of Practice
INTRODUCTION
The purpose of the NAMRI Standards of Practice is to establish a minimum and uniform standard for performing a mold inspection of a single-family to a four-family dwelling. The Standards set minimum requirements for describing and reporting conditions observed that could contribute to microbial growth. The Standards define and clarify terms, procedures, scope, conditions, and limitations as they relate to an NAMRI Inspection and Report.
INTRO
Client: A person who engages the services of a mold inspector for a mold inspection assignment.
Component: A part of a system.
Describe: To report a system or component by its type or other observed, significant characteristics to distinguish it from other systems or components.
Mold Inspection Report: A written evaluation prepared and issued by a residential mold inspector upon completion of a mold inspection that meets the standards of practice as established by NAMRI.
Inspect: To visually examine readily accessible systems and components of a building in accordance with these Standards of Practice, using normal operating controls and opening readily accessible access panels.
Mold Inspection Agreement: An agreement signed by the client prior to the start of the mold inspection that contains, at a minimum, the full name and address of the client, the address of the home to be inspected, the date and time of the mold inspection, the price of the mold inspection, and the scope and limitations of the inspection.
Readily Accessible: Available for visual inspection without requiring moving of personal property, dismantling, destructive measures, or any action which will likely involve risk to persons or property.
Structural Component: A component that supports non-variable forces or weights (dead loads) and variable forces or weights (live loads).
System: A combination of interacting or interdependent components, assembled to carry out one or more functions.
Unsafe: A condition in a system or component that poses a significant risk of personal injury or property damage during normal, day-to-day use.
PURPOSE
The purpose of a mold inspection is to detect the presence of suspected mold growth in the inspected areas of the subject property. The mold inspection Report communicates the information to the client through a written summary that describes the suspected microbial growth along with property conditions that could contribute to microbial growth. Additionally, the report may include the results of laboratory testing on suspected mold samples taken from the structure during the inspection.
SCOPE
The scope of the inspection is a visual observation of the readily accessible areas of the building, components, and systems that is limited to the readily accessible and visible areas and the systems identified as follows: Grounds, Exterior, Structure, Plumbing, Interior, HVAC, and Sampling protocols.
LIMITATIONS
The mold inspection is limited to the readily accessible and visible systems and components of the home. The inspector shall not dismantle and/or move equipment, systems, furniture, appliances, floor coverings, finished or fastened surfaces or components, personal property or other items to conduct this inspection or otherwise to expose concealed or inaccessible conditions. The inspection will not include destructive testing of any kind. Certain structural areas are considered inaccessible and impractical to inspect including but not limited to: the interiors of walls and inaccessible areas below; areas beneath wood floors or over concrete; and areas concealed by floor coverings. The following conditions are NOT within the scope of this Limited Mold inspection:
Areas to which there is no access without defacing or tearing out lumber, masonry, roofing or finished workmanship.
Surfaces concealed by floor and wall coverings or furniture.
Portions of the attic concealed or made inaccessible by insulation, belongings, equipment or ducting.
Portions of the attic, roof cavity, or under floor crawl space areas concealed or made inaccessible due to construction.
Portions of the sub area concealed or made inaccessible by ducting or insulation.
Enclosed bay windows and enclosed boxed eaves.
Portions of the interior made inaccessible by furnishings.
Areas where locks prevented access.
Areas concealed by heavy vegetation.
WARRANTIES AND GUARANTEES:
The written mold inspection report is not intended to be used as a guarantee or warranty, expressed or implied, that the items inspected are mold-free, or that concealed conditions conducive to mold do not or will not exist. Problems may exist even though signs of such may not be present during the inspection.
The Standards provide minimum guidelines for the Inspector, and outline what the Inspector should inspect, identify, and report on. The guidelines provide the minimum contents of a written mold report and are not intended to limit the Inspector from performing additional inspection services.
INSPECTOR QUALIFICATIONS
NAMRI members have demonstrated extensive knowledge of mold inspection by acquiring accredited mold inspector education and by passing the NAMRI Exam, which is a national exam sponsored by NAMRI. Members are required to obtain approved continuing education to maintain their membership.
STANDARDS OF PRACTICE

Hamilton Clinches F1 Championship No. 6 at US Grand Prix in Austin, Texas
Lewis Hamilton secured his sixth Formula One championship with a second-place finish Sunday at the U.S. Grand Prix, a race won by his Mercedes teammate Valtteri Bottas.
The British driver now ranks second in F1 history behind German Michael Schumacher's record seven titles. Hamilton has won the last three season championships and locked this one up with two races left.
He has been a dominant force at the Circuit of the Americas, with five wins here since it opened in 2012, but a poor qualifying set up a start from fifth.
Hamilton quickly bolted to third on the first lap as he passed the Ferraris of Sebastian Vettel and Charles Leclerc. From there, Hamilton looked to be in the hunt for his sixth win at the track while knowing he could coast in for the championship, because a finish as low as eighth would clinch it.
He still fought hard for the victory before fading late in the final five laps to fall behind Bottas, who was on fresher tires.
"Still we rise!" Hamilton radioed to his garage on a lap after the checkered flag.
Sunday was the second time Hamilton secured the championship in Austin, matching his 2015 title, when he fought off Mercedes teammate Nico Rosberg in the final laps to get the victory. In 2017 and 2018, he clinched the title in Mexico City without reaching the podium either time.

Hamilton could have rolled through a lazy Sunday drive had he wanted to, but championship drivers seldom do. Not when in pursuit of history.
"It's an honor to be up here with these (past) greats," Hamilton said. "My dad taught me when I was like 6 or 7 years old to never give up. That's our family motto."
Bottas was the only driver still mathematically in the hunt for the title, but just barely. Bottas had to win and have Hamilton fade to ninth or lower in order to extend the championship to the Brazilian Grand Prix in two weeks.

Saturday's qualifying left Hamilton starting from the third row as the cars bolted uphill into the blind left turn that can make the field become a demolition derby. Hamilton stayed clear of the dangerous traffic, giving Red Bull's Max Verstappen and Ferrari's Leclerc plenty of room to maneuver to avoid a collision.
Hamilton wasn't content to stay there.
He quickly reeled in and zoomed past the Ferraris into third halfway through the first lap. From there it was a matter of settling in for a long race to see whether he could make a move for a championship victory.

Hamilton grabbed the lead when Bottas pitted for tires and he didn't let it go without a fight. He defended against a Bottas pass with six laps remaining before finally surrendering the spot on the next lap.
Verstappen was looking to pass Hamilton on the final lap, but a yellow flag caused by Haas driver Kevin Magnussen ended the threat and gave Mercedes the 1-2 finish.
The Circuit of the Americas had a special spot reserved for the championship car next to the podium winners for the post-race celebrations.
