We deeply regret to learn about your recent experience. The presence of mold can indeed have detrimental effects, and it can arise from various factors, not solely insulation-related issues. In accordance with our agreement, you had opted out of the insulation options in order to minimize costs for the project. Furthermore, you had explicitly mentioned that the designated area was intended for storage and laundry purposes in the basement, rather than for residential use. Subsequently, we did make attempts to contact you after the expiration of the warranty period, which transpired two years ago, with an offer to rectify the matter at a significantly reduced cost compared to your initial request. However, it appeared that you were seeking a resolution without incurring any expense. As an investor/landlord, we comprehend your desire to secure the most advantageous arrangement to maximize your profitability. Unfortunately, collaborating with you proved to be an unfavorable experience. We feel compelled to caution other businesses about engaging with this individual, as he has a tendency to negotiate excessively, exhibit late payment tendencies, and ultimately, after a span of three years, attempt to hold you accountable for an issue and demand complimentary services.
