This was one of the three home that made me initially start this convo. Then I got turned down and got frustrated. I always charged more for second story cause thats what I thought everyone did. lol Booked the job and cant complain.
When I first started I found a mixture of folks charged the same for 2nd floor and some charged more. I never saw where it was double for 2nd, usually a buck or two. For me, I just kept it the same price for both as I gained experience and speed and figured out a fair price for me and my closing rate. I wanted consistency in time so I could calculate a repeatable rate that would tell me estimated time by my job price. It took a while but I made it happen to where my dollar and time to earn it are calculable to me. If I had over priced one set of basically the same windows over another it would have screwed up my whole calculation.
This is mostly why you need to set a consistent formula to work from. After a short time you can tweak as needed where your averages get a wee bit askew. Do not expect to run perfect numbers from the get go. Your actually starting from no knowledge trying to be King. Walk before you run.
Storm on it? One price in and out, all sides.
No storm on it? Whether a casement, double hung, bay, frenchies, whatever… another price.
Over 10 feet up on the inside? Another price for Skylights and Palladians.
Outside only? 3/4 of the above prices.
Keep it simple. A per unit price allows us to do 90+% of our bids over the phone or by looking at online satellite maps. I never understood the need to count panes. Thats time taken away from actually cleaning windows and making money.
This. Is. Incredible.
