We had a modular home put up - LOVE IT. Our contractor was a real bozo!! We had it set over a basement. We asked that the stairs to the basement be installed right away. They were not installed for THREE WEEKS. During that time we had to crawl in thru the basement window to install the drywall we were putting up on the basement walls. The only reason the stairs were put in when they were is that it was raining outside! Building/remodeling is stressful enough without the contractors jerking you around. Actually, the contractors are usually the ones causing the stress!
