1. You can’t get a new window installed for $189. Many remodeling companies have flyers that reach our Richmond mailboxes fairly frequently that advertise cheap window replacements. Advertising $189 for a replacement window is almost always a bait and switch. The cheapest double pane windows are priced at about $125. If you find a contractor willing to arrive at your home, remove your old window, install a $125 window, install trim, apply caulk, and then dispose of the old window for a gross profit of $64, call us and let us know. We want to meet him. When you factor in the contractors other costs, his net profit would probably be around $2. You aren’t going to get a window installed for $189, but that doesn’t stop window salesman from advertising that price. Read on to see what you can expect to pay.
