A good starting point for determining the budget of your kitchen or bath remodel should be at the project estimator from contractors.com. There are also project estimators for roofing, decks, and additions. These estimators take into account your geographic area as well as the size and scope of your project and cost of materials you’ll use. After submitting the details of your project the estimator will provide you with a figure that should consider in the “ball park” of what your project will cost. Knowing what to expect from a bid should help relieve the sticker shock as well as help you plan for future projects.
