Heck it even gives you some insight into calculating waste…
What about calculating for waste?
Yes calculating for waste is a VERY IMPORTANT thing. Some contractors calculate up to 30% on top of the raw exterior square footage (just the parts that will get vinyl siding) but it really depends on the project. Back in our contracting days we used to get our waste down between 5~10% (max) but we had to be very consious of reusing our cut-offs and plan the order of the walls we would do (plan our cuts). Most skilled vinyl siding installers will probably need to calculate around 15~20% on most projects. Your results may vary. There honestly is A LOT of skill that goes into bidding and installing vinyl siding. Take your time, proper planning in the begining will save you a lot of potential headaches in the long run.
