WoW replaced 12 old, wood double hung windows in our house. Instead of the same old window, we worked with WoW to get the Okna company to build custom slider windows with the trim / inlay a very specific way. From the first time we met the sales rep in our house, it was clear we were dealing with a company that treated potential clients differently compared to other window companies that walk door-to-door. The WoW sales rep was very honest, direct, and patient as we iterated over various design options. No one at WoW questioned us when we went with our chosen design that actually saved us money - they cared more about us being happy with our choices, not just the revenue. At the day the work was done, the team showed up and had everything our and replaced in the time they estimated. The crew cleaned up everything well, and they left behind some caulk/sealant for us to touch up with after we did some other modifications to our trim post-replacement. I would definitely recommend WoW to anyone.
