    I am updating the review to respond to the business's calculated misrepresentation of the facts and…read morean attempt to minimize severe, documented building code violations. For prospective customers reading this, here is the verified context: Fraudulently advertising yourselves as a "James Hardie Elite Preferred Contractor" to secure the job, only to systemically violate the manufacturer's strict installation guidelines, is not a "punch-list" oversight--it is deceptive marketing and a material breach of contract. Puncturing an internal PVC plumbing pipe, illegally wrapping it in black duct tape, and immediately hiding it behind the new siding is not a 'punch-list' item - it is active fraudulent concealment. The 'Fraudulent' Financing: We authorized the payment because they claimed to follow actively concealed the duct-taped plumbing. Inducing a customer to authorize a loan by hiding severe damage is the legal definition of fraudulent concealment. Contradictory Public Statements & The BBB Complaint: JP Exteriors is using public platforms to feign cooperation. On our active BBB complaint, they claim they are waiting for our independent inspection report before taking action. However, their own written record proves they inspected the property themselves on June 11th and issued a superficial patching offer on June 22nd. The very next day, they explicitly stated in writing they were not willing to expand their scope to a full replacement, formally refusing to cure the hidden defects before our third-party inspection was even conducted on June 24th. The 42-page independent inspection report, which we received on June 29, definitively confirms that the widespread, concealed code violations and structural deficiencies cannot be resolved through superficial patching. The report details systemic failures, including improperly installed weather-resistant barriers, missing flashings, overdriven fasteners, damaged boards, unsealed wall penetrations, and an internal PVC plumbing pipe that was punctured by a fastener and actively concealed with black duct tape. The Manufacturer's Involvement: James Hardie is indeed involved, to the extent that the manufacturer offered to provide free replacement materials to JP Exteriors so they could execute a proper rework. JP Exteriors leadership actively refused this offer. We stand entirely by our documented evidence, our 42-page forensic inspection report, and our active fraud dispute with the Texas Attorney General's Consumer Protection Division. The video proof of punctured plumbing remain on this review.

    This was by far the worst contractor experience I've had…read more I hired Rick to remodel our closet with bifold doors. During the initial consultation, he agreed the design was feasible and promised the project would be completed in 3-4 days. Five days into the project, he suddenly claimed the bifold doors were not possible and proposed changing the entire design to cabinet-style doors instead. This should have been identified before demolition began, not after work was already underway. From that point on, I was repeatedly told, "We'll finish tomorrow." That promise was made day after day for 19 days. Eventually, after nearly three weeks of delays and little meaningful progress, I asked them to stop work and remove their tools. I then had three independent contractors inspect the work. Two of them told me it was among the poorest closet workmanship they had seen. The issues included: * Panels cut to incorrect dimensions * Cabinet pieces shaped incorrectly * Poor fit and alignment * Work that would cost more to demolish and rebuild than to complete properly In the end, I paid for a project that accomplished virtually nothing except leaving me with demolition and additional repair costs. The worksite was also poorly managed. Although I was promised a clean work environment, they created excessive dust throughout the room and garage and rarely covered furniture or flooring unless I specifically asked. At the end of each day, I was often left cleaning after them myself. Safety was another serious concern. My toddler found a loose nail in the hallway during the project. Thankfully we noticed it before anything happened, but leaving sharp construction debris where young children are present is completely unacceptable. As the project progressed, work slowed dramatically. Some days they only worked a couple of hours, and there were 4-5 days where no one showed up at all without meaningful communication. To make matters worse, after all of the delays and poor workmanship, I was asked to purchase my own cabinet handles to save them roughly $30. The biggest disappointment wasn't just the quality of the work--it was the constant broken promises. If the project had been honestly scoped from the beginning, I could have chosen another contractor before losing nearly three weeks of time. I have extensive photos documenting the progress from day one through day nineteen and will be uploading them so others can judge the workmanship for themselves. I cannot recommend this company.
