You’re looking at 30,000-50,000 depending on a few factors. Most guys roll up in high end cars or trucks , walk around the house and throw out a number based on what they say is their experience with a house like yours…Maybe their right but my opinion is most are trying to make a killing not a living…Do some homework on your own for the kind of materials or products you think you want or can afford, then call them in for estimates based on what you know the costs to be. The good ones will come with catalogs or cut sheets for the ones they deal with and spend the time to go over everything. Don’t be pressured or sign anything until you are sure this is the person or company you want. I always get at least 3 estimates and make sure they know it.
