## Warning Regarding Selection of Mold Removal Services Before the Rainy Season
Mold Tori Gyosha Dot Com, a specialized comparison and ranking site for mold removal services, is issuing an alert to help consumers avoid misconceptions when choosing providers, in preparation for the increased mold issues expected during the upcoming rainy season.
Recently, search results for terms like 'regional name + mold removal service,' 'best mold removal service,' and 'mold removal service ranking' display numerous comparison and ranking articles. While these can be helpful, some are operated or written by the mold removal services themselves, or include advertisements and PR content.
The issue is not the ranking article itself, but that consumers may decide on a service provider based solely on the ranking, mistakenly assuming it is a 'neutral evaluation by a third party.'
Especially during the rainy season, when indoor humidity rises, mold is more likely to grow in places like bathrooms, closets, behind wallpaper, around windows, inside air conditioners, and underfloors, leading many to search for services urgently. In such times, it is crucial to check not just the ranking, but also the operator information, authors/supervisors, PR disclaimers, evaluation criteria, detailed pricing, chemicals used, and warranty details.
## 1. Mold Growth Increases Before and During the Rainy Season
Before and during the rainy season, outside air humidity rises, and indoor humidity becomes trapped. Mold is particularly likely to grow in areas with insufficient ventilation or prone to condensation, such as bathrooms, closets, behind wallpaper, around windows, inside air conditioners, and underfloors.
According to regional surveys conducted by Mold Tori Gyosha Dot Com, the number of inquiries regarding mold growth has shown an increasing trend from 2022 to 2024. Monthly trends show that inquiries tend to concentrate between March and April, June and July (start of the rainy season), and September and October (autumn rain season).
Mold in homes can lead to not only aesthetic unpleasantness but also musty odors, deterioration of wallpaper and wood, spread into building materials, and additional costs due to recurrence. Many people are also concerned about their health, including allergies and asthma.
It is important to perform inspections early when noticing initial signs such as 'slight darkening,' 'musty odor in the closet,' 'odor when turning on the air conditioner,' or 'repeated mold growth in the same place,' and to address them before they spread.
## 2. 'Recommended Rankings' May Be Created by the Services Themselves
Mold Tori Gyosha Dot Com has previously issued warnings regarding the fairness and transparency of mold removal service rankings.
Some comparison and ranking articles appearing in search results are not created neutrally by third parties; they may be operated or written by the mold removal services themselves, or by affiliated services, and include advertisements or are configured to lead to inquiries for specific services.
Such articles themselves are not necessarily a problem. Sometimes, ranking or comparison formats are used to introduce features or service areas of one's own service. Also, some clearly state PR disclaimers or provide operator and author information.
However, reading just the title or heading may lead consumers to interpret them as 'fair, third-party rankings' or 'objective recommendations.' Especially when feeling anxious about mold odors or black mold and searching for services in a hurry, they might decide on a provider based solely on the ranking or heading.
Therefore, when viewing ranking articles, it is important to confirm the following:
- Who operates the article?
- Who wrote/supervised it?
- Is there an advertisement/PR disclaimer?
- Are the evaluation criteria clearly stated?
- Is the operator's own or affiliated service placed in a prominent position?
- Is it possible to verify pricing and warranty details?
- Have you cross-referenced with multiple sources, such as official sites and reviews?
When choosing a mold removal service, while using rankings as one reference, it is crucial to verify multiple pieces of information such as official websites, construction examples, detailed estimates, warranty terms, and reviews before making a final decision.
## 3. Cases Where Consultation Did Not Lead to Expert Response
Misconceptions caused by ranking articles go beyond just how information is presented.
We have received reports from consumers who inquired because they thought a company was a 'mold removal service' based on a ranking article, but were turned away because the company was actually a general housekeeping service, not a specialized mold removal and prevention service.
In such cases, consumers inquire thinking 'they must be a specialized mold removal service since they are in the ranking.' In reality, they may not handle investigations into the cause of mold, moisture content checks, specialized mold removal, anti-mold treatment, or recurrence warranties.
Mold removal is not just cleaning.
It requires assessing not just surface dirt, but also the cause of mold, the extent of contamination, the moisture content of building materials, the safety of the chemicals used, anti-recurrence treatment, and warranty details. Choosing a service solely because it is in a ranking article may result in failing to receive professional mold対策 and lead to recurrence and additional costs.
## 4. The Problem is Lack of Clarity in Interests and Evaluation Criteria
Ranking articles themselves are not inherently bad. Information that allows users to compare multiple services can be a helpful guide.
The problem arises when it is unclear who operates the ranking, who the authors are, the basis for ranking, the evaluation criteria, PR disclaimers, or whether there is advertising or referral revenue, while consumers interpret the ranking as 'objective superiority.'
The Consumer Affairs Agency explains that displays that do not allow the general consumer to recognize that it is an advertisement, despite being so, may be a problem under the Act against Unjustifiable Premiums and Misleading Representations as stealth marketing. Regarding comparison advertising, it is also important that claims are objectively proven, figures and facts are cited accurately and appropriately, and comparison methods are fair.
For consumers choosing a mold removal service, it is crucial not to conclude 'it's safe because it's #1' or 'it's a specialist because it's recommended,' but to check who created the ranking and by what criteria.
Mold Tori Gyosha Dot Com strives to provide information that does not mislead consumers by clearly stating operator information, evaluation criteria, the presence of advertising/PR, and the reasoning for ranking to enhance the transparency of the information provided.
