Summary: Insurance exploitation/fraud and sleazy sales practices. I contacted Gen Ex with a clear description of the work I wanted done on my house. After coming for an inspection, I received a follow up trying to get me to submit insurance claims for hail damage to replace my siding and a new roof. The roof is only a few years old and I had not experienced any hail damage. I explained that and told the sales rep that I only wanted a quote for the work that I had requested. He continued to push while also trying to play an angle of convincing my girlfriend that the work SHOULD be done in the hopes that she would insist I agree to all the extra work. Very pathetic and sleazy sales tactic. When I asked that he send the quote only for what I asked, he again insisted I consider making a false insurance claim and would send the quote after I've made a decision about that. It is clear that Gen Ex is only interested in exploiting your homeowners insurance to extract the most money out of your repairs rather than doing honest and quality work. They are unfortunately a part of a large trend of contractors exploiting this system which is causing premiums to rise and putting home owners at risk of being denied insurance coverage in the future. A further response to the response added below: I would have been more receptive to the inquiry if my home had any hail damage. At this point I might give the benefit of the doubt that the wrong house was inspected; however, the representative spoke to my partner. When I arrived home the only thing she had to say was "he was strangely insistent that we have hail damage to our siding". To say that there is any damage to the siding warranting an insurance claim is VERY FAR reaching. None of the other 4 companies that came to quote this job made any comment or note about poor condition of/damage to the roof or siding. I did take your advice from the strangely timed text message you sent me at 9:45pm trying to explain how my experience

Dear Kyle, Thank you for taking the time to share your experience. We're truly sorry to hear that you were dissatisfied with your interaction with our team. Your concerns are important to us, and we appreciate the opportunity to respond. After inspecting your home, our project manager observed what appeared to be significant hail damage to the aluminum siding. As a courtesy, we obtained a certified storm report for your property, which confirmed that a large hailstorm had occurred in your area within the past year. Our goal was simply to inform you of this and help you understand all available options for addressing the damage. We want to emphasize that we never encourage or condone false insurance claims. It is standard and responsible industry practice to inform homeowners when legitimate storm-related damage is found and to help them understand their potential coverage options. Ultimately, the choice to file a claim is entirely up to the homeowner. Additionally, we’d like to clarify that we do not chase storms, knock on doors, or engage in high-pressure sales tactics. That’s something we take pride in. Our project manager was not attempting to be pushy or misleading in any way — he was simply doing his job by sharing his professional assessment and trying to be helpful. We are proud of our reputation for honest, high-quality work and customer-first service, and we take accusations of unethical behavior very seriously. If you’re open to it, we’d welcome the chance to speak with you directly to clear up any misunderstandings and address your concerns. Please don’t hesitate to reach out to us at 815-388-3561 or email - genexmchenry@gmail.com Sincerely, The General Exterior Construction Team

This company is who you want to do business with. I've had a great experience with them rebuilding my porch which turned out to be a much more difficult job that both they and we anticipated. They were skilled and kind. That was several years ago. Now a new problem has developed, and they're quoting us on a more permanent solution, but we called today to ask about a temporary fix until the main work is done next month. Its sounds crazy to say but not long after hanging up the phone someone was at our door fixing the issue. They didn't wait. They didn’t "see what they could do". They showed up and just plain fixed it. This is a whole other tier of customer care and support. Never have I been treated as well as General Exterior has treated us. I would recommend them to anyone without hesitation. Incredible people, outstanding work, and otherworldly customer support.

With an evening of high winds, a piece of my siding came loose and was hanging from the top floor. I stopped by the GenEx office and asked for someone to check it out. They actually came that same evening and made the repair. I was very grateful since we were expecting more windy conditions and I worried about losing more siding. Thank you very much for your quick response and professional work. I'll definitely use your company again when needed.

Thank you so much for the kind words and for trusting us with your project—we truly appreciate it! We were happy to assit the high school district’s building trade program. At your request, the installation was completed during cold-weather conditions, which can add an extra layer of complexity. Our team took the proper steps to ensure a quality installation, including storing the materials in our warehouse so they could properly acclimate before installation. We’re glad we could respond quickly after the windstorm and take care of the few shingles that were affected. Standing behind our work and being there when our customers need us is always a top priority. Thank you again for the recommendation—it truly means a lot to our entire team!
