Try to be
Try to be as accurate as possible, knowing that the final tally will be a small percentage different. You can walk around your local home improvement store or browse the internet to get some good quotes. You can even compare different suppliers and keep track of the best prices at this point.
If you don’t plan on doing all the work yourself, you will need to factor in labor costs. The best way to do this is to ask contractors to bid on the project. Try to have all the products picked out ahead of time, as this will allow the contractor to give you an accurate estimate. Carefully examine each of the bids to make sure they include a breakdown of all the components so there are no surprises in the end. Not only should you compare the final prices, but also compare each detail.
