True Statement: there is nothing stopping anyone from setting up a mould remediation company and spraying, blasting, removing some affected material, etc... without having a proven or verifiable system in place. Yes, there are certification programs and there are professional organizations to which one can belong. The content of the former is unregulated and opinion-based; involvement in the latter serves as a bare minimum to show that a company is at least serious enough to have sought out and paid for membership. For your edificaion HIP has gone through those bare minimum hoops: it is everything else that we have done that sets us apart.
Mould: To See or Not to See
HIP most often comes across mould in secondary inspections for real estate transactions. We are referred to when the home/buidling inspector finds an unknown black substance in a place known for mould growth: attics, basements, crawl spaces, cold cellars, and one-off locations where a leak may have occurred. There is some risk that the inspector faces in recommending secondary inspection: their insurance policy wording does not allow for mould identification and flagging that which could be mould stands to stall a transaction for realtors, sellers and buyers (+ scare buyers).
Treatment Cost has no Correlation with Efficacy
We do have an entire section on Industry Comparisons, but would like to touch on the wide range of mould remediation costs that we come across in the bidding process. This is part and parcel to the lack of regulation, and it's noteworthy in that there is little to no quality correlation, rather the correlation seems largely to do with the invasiveness of the process (and the expense incurred by contractor). Taking the very same property / same amount of mould / same materials affected, we have seen quotes ranging from $500 (spraying bleach) to $40,000 (replacing a perfectly good roof). Seriously. Of note: neither were guaranteed processes.
HIP Has the Only Provable Mould Treatment Method
HIP has a complete "turnkey" process that takes into account everything from the science side of matters (namely the structure of mould, the structure of common building materials, ventilation, and moisture considerations and how all interact wtih one another); the fear -- founded or not - that the discovery of mould can elicit in a property owner; and, the health and associated liability issues that can arise if mould is not killed and prevented from returning. Because of the unregulated nature of mould remediation, you should seek a company that can provide references and testimonials (including some from at least 2 years ago to show that the mould has not returned to the site), a non-time-limited guarantee where they have been around long enough to show that claims on guarantee have not bankrupted them, third-party passing air quality tests post-treatment, and mould remedation specific insurance. Naturally, HIP can deliver on all of the above.
