2. You don’t need to pay $1000-$1500 per window. Those unscrupulous, shameless conman will have you believe that you are getting a deal at $1000-$1500 per window (after advertising them for much cheaper). There is absolutely no reason to pay that much for your standard double pane window. They may even tell you that if you sign the contract that day (in the middle of the night while they are still intruding in your home) that they will cut you a deal for $950 a window. Only a custom, very large specialty window should come close to that price. You can expect to pay around $300-$600 per window. They may justify the price by claiming 40% energy savings, but that isn’t true either. Read on.
