I have two manuals that I use, one for interior and one for exterior. they include all types of jobs, small to large and include materials, time to finish and factoring system for different eco locals.
I use mine all the time.
Remember, there are two seperate manuals.
Exterior Home Improvement Costs Updated sixth edition RS Means Copy right 1998 R.S. Means Company, Inc. Construction Publishers and Contractors 63 Smiths Lane P.O. Box 800 Kingston, MA 02364 781 585 7880
a Construction Market Data Group company
The books are about $25 each.
Now, I use this manual as a guide, but I first shop local competition for a much better feel of what the market will bear. But, this is a good starting place and one that you can show to a tight wad customer that says your work is too expensive, then you pull out your book and show them the book price.
I usually go about 80% of the book price. I found that its about 20% higher than my market.
I highly advise you find this book and have it with you on all bids. Very helpful.
