    We ordered windows from Window World on July 6, 2025 after an in-home meeting with their rep, Greg, attended by myself and my builder. We specifically asked for the lead time for our exact order, which included custom sizes and bronze exterior / white interior factory finish. We were clearly told that the expected turnaround time was 6–8 weeks from the time of order. Based on this information, we proceeded with the purchase and structured the remainder of our construction timeline accordingly. Based on the stated lead time, our windows should have arrived by the first week September 2025 at the latest. At approximately six weeks post-order, I attempted to follow up for a status update. Multiple voicemails were left over several days without response. About a week later, I was informed that Greg had been on vacation and that the windows were now expected to arrive in another 2–3 weeks, which still aligned reasonably with the original estimate. However, after that point, the communication deteriorated significantly. At 9 weeks post-order, we were told “hopefully next week.” This same message continued for another 5 weeks, despite repeated follow-ups. On November 3, I left another voicemail. Greg returned my call on Nov 5 and stated the following (paraphrased): “Normally standard white windows are 6–8 weeks. Once you get them painted or colored, they have to ship them to another plant to get painted, and it takes longer—usually about 10–12 weeks.” This explanation was never disclosed at the time of sale, despite us asking specifically about lead times for our chosen configuration. Had this information been provided upfront, we would have made a different purchasing decision or adjusted our construction schedule accordingly. Ultimately, the windows were not delivered until November 9 — approximately 16 weeks after the order was placed, more than double the original quoted timeframe (and beyond the timeline even IF they had given the 10-12 weeks in the first place) Key Issues: 1. Misrepresentation of lead times when directly asked about this specific order configuration. 2. Failure to return calls and provide timely, honest updates. 3. Repeated assurances that delivery was imminent when it clearly was not. 4. A significant domino effect on our construction schedule, including delays to drywall and finishing work. 5. Substantial financial impact, including: • Delayed move-in from Christmas to March/April • Additional months of rent while simultaneously paying a mortgage • Thousands of dollars in avoidable costs caused by inaccurate and misleading information I fully understand that delays can occur in construction and manufacturing. What is unacceptable is intentional or negligent misrepresentation, compounded by poor communication once the sale was secured. Had Window World been honest about realistic lead times—or transparent once delays became evident—we could have planned accordingly and significantly reduced the financial and logistical damage. This experience reflects a breakdown in honesty and accountability. I am documenting this not only to seek acknowledgment and resolution, but also so that future customers are not placed in the same position.

    I could not be happier. Everyone I've delt with has been nice and informative. If I ever have to have anything else done I will be asking for Logan personally. He was so quick, knowledgeable and kind. Thank you Window World!
