cost estimators for various building jobs

[hnash53]

Does anyone know of any online cost estimators for determining installation costs for various projects?  I am particularly interested in estimating siding installation.  But then that brings up another question:  If one is installing T 1-11 plywood for siding, then the costs will differ significantly from installing 6" shiplap siding.  4x8 sheets go up a lot faster than 12'x6" strips.

Any ideas or resources?

Thanks.

I have tried some programs but find that the most accurate is my spreadsheet with actual prices added by me + estimated time at estimated rate -- then you end up with a good guess.

This isn't an installation cost estimator but you might find it helpful and it could serve as a basis for adding labor costs as well.

This is a spreadsheet I've been meaning to share for some time. Just found it again
