Inside Tyler city limits, the City of Tyler issues the permits, and the work its list names includes retaining walls, roofing, electrical and replacing sheetrock, but it doesn't spell out insulation, so before we schedule your job we check with the city's Building Services office. If a permit's needed, we take care of it as part of our work and tell you up front, and the start date waits on that answer. The sheetrock rule matters on wall jobs, because the city wants a permit for new sheetrock even when no walls move. Contractors register with the city's permit system by sending in a copy of their license and a certificate of insurance, so it's fair to ask anyone you're thinking of hiring for both.
Your price turns on how much insulation is up there now, whether any of it has to come out, how many gaps need sealing and whether foam or blown-in fits your attic. The schedule mostly turns on that permit answer and on any removal work that has to happen first. We make the same drive from Longview out to Marshall and Kilgore, so a Tyler job gets the same crew lead, the same installers and the same order of work.
