We do give free estimates of course. Occasionally it is difficult to get to your home to look at it in a prompt manner, so we can also give you a ball park figure over the phone, too.
1). When you call, we can give you a figure to contemplate. 2).
If you decide the estimate is in your price range, then we schedule a day to do the windows. 3).
When we arrive we can give you an exact price. 4).
If we can't agree on a price, then we part as friends!
This system has worked well for us in the past and I can only remember 1 customer turning us down over the last 11 years of estimating that way!
