New siding is one of the biggest projects you will do on your home, and the installer matters as much as the product. Even the best siding fails early when it is nailed too tight, flashed poorly or hung over rotted sheathing. This guide explains how to choose a siding contractor in Knoxville: the Tennessee licenses to check, the insurance to ask for, red flags to avoid and 10 questions to ask before you sign.

Knowing how to choose a siding contractor protects both your budget and your home. The steps below take about an hour of homework and can save you thousands.
How to choose a siding contractor: the short version
If you only have five minutes, here is how to choose a siding contractor you can trust: confirm the right Tennessee license, get proof of insurance, favor a local siding company with years of work in your area, compare at least three itemized written estimates, and never pay more than one-third up front. Every good siding contractor in Knoxville should be comfortable with all five.
Step 1: Check the right Tennessee license
Tennessee has two license types that apply to residential siding, depending on the size of the job:
- Home Improvement license: required for residential remodeling jobs from $3,000 up to $25,000 in nine counties, including Knox County, according to the Tennessee Home Improvement program. Nearby counties such as Blount, Anderson, Loudon and Sevier are not on that list.
- Contractor license: required by the Tennessee Board for Licensing Contractors before a contractor bids or offers a price on a project of $25,000 or more, materials and labor included.
You can look up any license for free at verify.tn.gov. If a contractor cannot give you a license number, keep looking.
Step 2: Ask for proof of insurance
- Workers’ compensation: Tennessee requires construction businesses with one or more employees to carry it. Without it, an injury on your property could become your problem.
- General liability: ask for a certificate of insurance that protects your home if something is damaged during the job.
Step 3: Look for a local track record
Consumer Reports recommends choosing an installer with at least five years of experience in your area and checking references. A local company knows how East Tennessee’s humidity, heat and storms treat siding, and it will still be here to honor its warranty. Read recent reviews, check the Better Business Bureau, and ask to see finished homes near you.
Step 4: Compare itemized written estimates
Get at least three written estimates and make sure they cover the same scope: siding material and profile, tear-off and disposal, house wrap, flashing, trim, soffit and fascia, and cleanup. A low price often means something was left out. Our siding replacement cost guide explains what affects price so you can spot gaps.
10 questions to ask a siding contractor
- What is your Tennessee license number, and is it the right type for my job size?
- Can you show me certificates for workers’ comp and liability insurance?
- How long have you installed siding in the Knoxville area?
- Will your own crew do the work, or do you use subcontractors?
- Will you remove the old siding, or install over it? (Consumer Reports recommends removing it so damaged sheathing can be found.)
- How do you handle rotted sheathing you find during tear-off, and how is it priced?
- Is house wrap and flashing at windows and doors included?
- Who pulls the permit? (The Tennessee Attorney General says it should be the contractor, not the homeowner.)
- What is your workmanship warranty, in writing, and what does the manufacturer’s warranty cover?
- What is the payment schedule? Tennessee guidance is no more than one-third down.
Red flags to avoid
- Door-to-door offers right after a storm, or deals that expire today
- Requests for cash or a large deposit up front
- No written contract, or a contract without dates, materials and price
- Asking you to sign over an insurance check
- No license number, no insurance certificates, or no local address
The Tennessee Attorney General lists these same warning signs in its home-repair consumer alert.
About manufacturer certifications
Some manufacturers run contractor networks. James Hardie, for example, has a tiered contractor network, and states that it does not warrant the installation of its products. Certification can be a good sign, but it does not replace a license, insurance and a written workmanship warranty from the company doing the work.
