How To Choose a Window Company in Knoxville

With Knoxville's robust local economy, you're sure to find a reputable window company that aligns with your values and preferences. As you make calls, keep the following factors in mind:

Window Cost by Type

Replacing your windows is a substantial investment, so balancing cost with value is crucial. Although premium windows may be more expensive to buy, they often yield better long-term value due to their increased lifespan. The material, size, and style of your new windows have the greatest impact on your final cost. Single-hung windows often cost less due to their straightforward style and simple mechanisms, while new skylights cost more to prepare for and install. If you're undecided, a window specialist can help you figure out which options are best for your home.

In this table, you can find cost data for the most common residential window types to determine how much you might pay.

Window TypesAverage Cost
Glass Block$43-$555

Window Material Cost

Window prices also vary based on material. Each option offers unique advantages depending on your climate and energy-saving goals. Fiberglass and vinyl are readily-available materials, so they tend to cost less. Likewise, composites and aluminum look sleek and stay strong against the elements, so they tend to cost more.

Window TypesAverage Cost

Other Window Replacement Costs

Your contractor will factor the price for your windows and the value of their services into its total estimate. Make sure to assess the cost of installation, warranties, and any other additional costs that your project may require.

Experience and Training

The longer a window installer has served your area, the better its workmanship will likely be. Talk with a company representative to learn more about its guarantees, public and private credentials, and experience. Company websites often keep photo galleries showing off previous work technicians have done.

Licensing and Credentials

If your window work costs over $25,000, your installer will need a Tennessee contractor's license. There are three license classifications for residential work, and the application process involves a trade and legal exam.

If your job costs between $3,000 and $25,000, the installer may need a home improvement license if you live in Rutherford, Bradley, Marion, Hamilton, Knox, Haywood, Shelby, Robertson, or Davidson

Types of Windows Offered

The type of window you want should play a role in your company choice. Not every installer will necessarily be familiar with the window styles you want. A company website will provide more about the styles of windows it specializes in, such as:

  • Awning
  • Bay
  • Bow
  • Casement
  • Crank-out
  • Custom
  • Double- or single-hung
  • Egress
  • Garden
  • Jalousie
  • Picture
  • Sliding
  • Skylight
  • Specialty
  • Storm
  • Transom
  • Vent
Finally, pay close attention to the framing materials that a company uses. Each frame material has a different energy efficiency level, life span and price point. A company will usually specify whether the windows they set up use fiberglass, vinyl, wood, composite, or metal.

Customer Feedback

One of the best ways to vet a company is to see what other customers have written about their experiences. Trustworthy sources for customer reviews include Trustpilot, Yelp, and Google Speak with people you know who have used a company you're interested in, and ask a representative for a copy of its reference list.

Frequently Asked Questions About Window Replacement in Knoxville

Why should I hire a professional to install or replace my windows?

Replacing your windows is a substantial expense that greatly impacts your home's livability and energy performance. Hiring a professional window company to oversee your project ensures your windows will fit correctly, operate effectively, and be properly sealed. Companies also typically include a guarantee that covers required maintenance and most future repairs.

Does window replacement involve pulling permits?

Window replacement may involve securing permits, depending on your local building codes and regulations. Some communities mandate permits for window replacement projects if they involve structural changes or alterations to the window openings. We recommend checking with your local building department or consult a professional before proceeding with any window replacement work.

Do window installers also work with blinds and coverings?

Maybe. Numerous installers work with both windows and blinds, so you can design a window covering solution that adds aesthetic appeal and improves your new windows' performance. However, depending on your state, blind work can require a different license that a company may not hold. During your company search, inquire with each representative about blind installation. If a company does not offer it, they may delegate the task to a different company or recommend a retailer that can help you with blinds.
