    As of November 28, 2023 Pen Win has not refunded the monies he promised. When asked to provide documentation to prove me wrong he has also been unresponsive. Please refrain from providing him or his company with your credit card information. He even threatened to take me to court and that hasn't happened either. UPDATE The response I've received from Horace is not the response I would have expected from a legitimate business owner. The response I expected would have been. "What did I do to expect such a response from a customer" instead he is replying negatively. Completely shocking to me. I allowed Horace into my home and I believed, to my lack of knowledge on the process, to give this man monies upfront believing he was genuinely going to help me. I paid him in advance, which I found out later is not protocol. However, 2 hours later I told him I was seeking other estimates and to hold off until I chose a contractor. He was fine with this. Something so small has mushroomed into something catastrophic. I am asking him via this review to post this so called contract, which never existed, to show the people considering using Pen Win, LLC the documentation. Again, less than 2 hours after I paid him I called him back to inform him that I was going to get other quotes and he told me he was fine with this, yet he still used the funds, for what I have yet to determine. A honest business owner would have asked what can he do without all this confusion. This further verifies that this man is a true scam. Horace, if there was ever an agreement between you and I I'm requesting you post the contract on this website immediately with my full permission. I'm attempting to post the work you said you started but at this time there is no way I can show the world what condition my home is still in. How dare you lie about the services you have performed. Instead you should be asking me how you could have resolved the situation instead of pretending to perform work

    This matter is a fraudulent attempt to not only get free labor, but also get two refunds. We were contracted to repair an internal ceiling that fell. We came and gave an estimate and was contracted for the job. The client called Discover credit card and approved two payments. We only received one payment from Discover to start work the next day. When we arrived and completed a portion of the repair, the client wanted to shop around after work was completed to keep the walls from falling. We agreed to wait until 1pm of that day as requested . After waiting till 8pm that night for a job scheduled for the next day as requested. The client canceled the job. After we agreed for a porrion of the deposit to be refunded by Friday of that week. The client filed for a Credit card refund, with the understanding we already had a refund coming. So we contacted the USPS and had the deposit intercepted. So the plan was to not pay us, but for us to actually pay them. We are still owed for the labor done. We decided to refund Ms Rodgers. *We sent over a letter from our credit card processor and their contact information*We are being falsely accused to defame our company publicly. If we didn’t pay the client,it would be fraud and Discover would be contacting us or our processor. You can’t be scammed if a customer has admitted you paid them, and you approved the payment and had labor done.Every ounce of this is false. We now have performed and emergency repair to help someone, and now we are defending ourselves. Please go online and review our past clients reviews. We will update this case as it moves along. https://penwinwindows.com/reviews/

    - Updated at the bottom The initial experience with the salesman was good. He was knowledgeable, polite, and professional. The installation crew was great! They were fast, neat, polite, and professional. They even explained the process to my inquisitive daughter. From then on it went downhill. The date for install was never given, I had to call them multiple times to get them to schedule it. Then the screen that came with the door was broken. The installation crew apologized and immediately called the office to have them order a new one (score another point for the installation crew). That was over 2 months ago. I made calls to find out what was going on, but they ended in apologies and empty promises, I made texts and only got more empty promises. Nothing so far is getting them to actually install the screen. Maybe negative reviews will get them interested in giving us what we paid for. - Update: After posting this negative review, we were told the replacement screen would be in by that weekend. It was not. So the following week I called and requested a refund for the screen door. I was told it would be put in the mail that day.. 1 week later I called them again and they said it would be put in the mail, along with a gift card. Finally, almost another week later, I have gotten the refund for the screen and a gift card for Panera. This entire thing started in the spring, and is finally done. While I think it could have been a great experience, if they had followed through, I am saddened to see that it took a negative review to get their attention. However, as they did finally send my refund, I have upgraded the stars from a 1, to a 2 star rating.

    Horace sent his crew out to repair 3 pieces of rotted wood on my back door frame. They did an exceptional job at a very fair price! Thank you so much Horace. You are definitely on my list if I need any other similar repairs. I appreciate it!

    I have had excellent experience with Horace of Penwin. They replaced some windows in my townhouse. Everything went well. He went through all the details with me, explained everything, and communicated very well. They did what they said they would do. I'm gradually replacing the windows in my townhouse, and I intend to use them for the rest of the windows moving forward. On top of everything, Horace happens to be a great gentleman who is nice to work with.

    The communication was key. Our window well and window had to be replaced because of flooding due to the terrible work of a previous contractor. Our new window is high quality and our window well has been repaired . The owner of the business was responsive to all my questions and present to oversee the project at every step of the installation.
