We finally replaced our original windows (1967!) and are extremely happy with our choice of Windows on Washington. Everything about the processes was fantastic, from the information/ bid gathering to the planning to instalment to the product.
Initial consultation: we had several other bids from other companies with extremely pushy salespeople ("sign tonight or your "deal" will fall through!", even though the "deal" was approaching twice our other bids). Brandon from Windows on Washington was knowledgeable, professional, not pushy and he gave us a straight forward, no-nonsense bid. The contrast was dramatic.
Planning: WoW was extremely professional, and focused on our interests. When we changed our minds about the color of the outside flashing at the very last minute (3 days before the installment!), even though they had confirmed our initial choice twice the month before, they didn't bat an eye at the change. The color we wanted was not in stock, and they offered either to postpone our installment and get the color of our choice or to use another very closely matched color they had in stock. We chose the nearly identical color they had in stock, and I was impressed with how positive and accommodating to our desires they were.
Installment: The installment team, led by Joon, was outstandingly meticulous. The work was clean and efficient, I note that *every* single time they entered the house, they took their shoes off. We replaced all the windows on a large town house (29 windows!) and they were done in a day and a half, leaving the house spotless when they were done. They even removed and reinstalled the safety bars on the 7 downstairs windows (which I note that some of the other companies refused to do, saying we had to find our own outside contractor). Joon is a true professional who clearly takes pride in high quality work.
Product: The Okna windows WoW uses are great. Some other companies will try and disparage vinyl windows, but these are high quality, great looking windows. Simply put, it was one of the best contracting/ house project experiences we've had.
