Installed cost in Knoxville runs roughly 4% below the national average for this trade. Here's how we got to that number.
Project costs include three main components: labor, materials, and overhead. Material ships at national prices no matter where you live, and overhead is fairly consistent as well. So the main pricing difference between metro areas is labor costs. This is why a quote from a high-wage metro is rarely as far above the national average as people expect.
To get Knoxville labor costs, we compared the average hourly wage in the Knoxville, TN area to the national average hourly wage for this trade. (source: US Bureau of Labor Statistics, Occupational Employment and Wage Statistics, May 2025)
We found that the local trade wages sit about 18% below the national figure. Labor costs typically make up about 20% of a door replacement project cost, so the weighted difference between Knoxville and national averages is −4%. See methodology and sources.
It depends on the scope of your project, so you should talk to the permitting authority to find out what your project needs. In general, Knoxville permitting is simple compared to other metros we cover.
Permitting for structural and plumbing work in this area goes through Knox County.
You should ask each contractor if they pull the permits for you and if the fee for pulling permits is included in their quote. Also, tell them you need to see the written, approved permit before work starts.
