I wouldnt recommend the firm that I used. I had used them before with great results, but as I continued to use them, they continued to get worse and worse.

Also dont remember the cost but it was not cheap. Every house is different however. Our job was very big and involved new doors and windows, insulation, and a sheer wall underneath the clapboards. Not everyones project is intense as mine. Also, the San Francisco building department can be a tough one with all the rules we have in California.

Whatever you end up doing, be sure to check on your project many times a week. Pay attention to the little things. For example, I came home one day and found an outlet that I used to have just covered in the wall. They were just being lazy and didnt think I would notice.

Best of luck!
