- IIldin -3 days ago5.0Folks were on time and efficient at their work.
- MAMona Amirian3 days ago5.0We had an excellent experience with Window World! From start to finish, the entire job was handled professionally and efficiently. The installation team did a wonderful job and paid great attention to detail.
- GGGreg GAug 25, 20261.0Honestly, I've had good experience with WW in the past, they replaced all my windows in a CO home, and did a good job. This time, what an absolute disappointment and waste of my time. In my online request for a quote, I specified clearly that I was on an interior courtyard, 4 floors up. I wanted them to have full information. So the day of the appointment, an hour out, the salesman, Henry, calls up to discuss. After dancing around the topic, he - Tells me he doesn't necessarily need to come here to provide info on the replacement...an appointment I coordinated with WW - Discusses that he's looked at my home online, tells me when the building was built, and that the WW windows will likely be more efficient I catch on that he's telling me he's not going to make the appointment. I remind him that in my appointment request I didn't disguise my location in the building. Then he mentions that condo rules may prohibit their windows and they'd need scaffolding, so I should seek out a commercial or multi-unit window installer. (Other units have had windows replaced here, I know for a fact) These may even be valid points. But they should've been made at least a week ago. And don't point fingers at the marketing team who sets up the leads because someone waited until today to look more closely at the details of my location. Both the marketing team and the salesman own part of this. All in all just a poor sales experience. My general impression was that WW wouldn't make money on the window install, so they offered a handful of reasons they couldn't. Surely their (good) prices mean they need volume. Combined with their poor planning and wasting my time, it was a pretty sour experience.
