  I was really pleased with the initial estimate and decided to go with this company – their presentation just stood out compared to the others. The prices were comparable, and Jose seemed knowledgeable and professional during his initial visit in January 2025. However, things quickly went downhill. I initially assumed Todd was the owner and contractor, but we started experiencing some communication issues around March. Todd told me my windows hadn’t been ordered because the deposit hadn't been paid, and Jose reassured me he’d placed the order (including the shutters and one window with privacy glass). The delay was due to my HOA needing to approve the window. Unfortunately, when the windows were installed, there was a significant problem – the shutters didn’t match the windows at all. It’s baffling how a company specializing in windows and shutters could make such a basic error. Worse, they installed a clear window above the staircase, which was the entire reason I’d waited until December 2024 to place the order. I contacted Jose about this in April, concerned that no one had flagged the mistake, but he assured me he’d get the correct parts and it would take about two weeks. I followed up with him on April 21st and again on April 25th, but I never received a response. Despite this, I paid for the full installation, figuring I was stuck with the incorrect window since I wasn’t there to oversee the work. Honestly, at this point, I don't see a way this will work out and I'm hoping this experience doesn't happen to anyone else. report abuse

  “I’m getting increasingly frustrated with the progress on my window order, which I placed back in December. There were initial problems with the order, and they’ve had to start over in January. I’m still waiting to hear back from Todd and Jose about the status – I need an update as soon as possible, please could you call me to discuss this?” report abuse
