On average, homeowners in Knoxville will spend around $280 per window*. Below are additional cost breakdowns. *Cost data based on sample pricing for window installation from multiple retailers and adjusted for local cost of living.

When To Replace Windows

Installing new energy-efficient windows can significantly enhance your home's appearance, value, insulation, noise reduction, and comfort. Some clear indicators it's time for new windows include the following:

  • Fogging between window panes, condensation issues, or rotting window frames that allow moisture intrusion into the home.
  • Inefficient and outdated window styles that take away from your home’s curb appeal.
  • Cold air and drafts coming in through old, loose-fitting windows.
  • Windows that are hard to close, open, or lock properly due to age and wear.
  • A chilly house and high energy bills due to poor insulation.

How To Choose a Window Company

For a successful window replacement, you want to find an installer with proven expertise. Below, we cover the most important considerations when selecting a window installer.

Experience

Make sure you hire an experienced local installer with a proven track record of successfully installing and replacing windows. Providers that have served Knoxville for years are more likely to understand the local climate and local homeowners' needs. Get references from recent clients to confirm a company provides quality installations.

Certifications

Look for installers that are backed by top window manufacturers and accredited by top industry associations, including the Fenestration and Glazing Industry Alliance, formerly known as the AAMA. Appropriate accreditation indicates that a provider has been appropriately trained in installation best practices. Ensure installers are employees, not subcontractors. Verify that any technicians assigned to your job have the right certifications.

Reputation

Read through online reviews, check the Better Business Bureau (BBB), and request local references. Review customer feedback to verify that the provider consistently delivers quality work and good customer service. Avoid providers that have complaints of shoddy work or unfinished jobs.

Process

The most qualified company will take time to provide you with a detailed project plan, timeline, expectations, and reviews of all material and installation options. Beware of vague quotes or timelines that lack clear and specific information. Look for continual communication throughout the process to avoid surprises later on.

Warranties

Search for window installers that back their installations with warranties on labor and materials. This shows confidence in their work. Target companies that offer unlimited lifetime warranties that can pass to new homeowners.

Materials

Confirm that a window company offers durable, long-lasting windows and leading energy-efficient window bands that fall within your budget. Research choices with enhanced UV protection, good energy ratings, and design flexibility, and verify that the materials come with their own manufacturer warranties.

Frequently Asked Questions About Window in Knoxville, TN

In Knoxville, the best time to install windows is when temperatures are mild, generally during spring, winter or fall. This allows professionals to do their work with less worry about the weather.

The right type of replacement windows for your Knoxville home depends on when your home was built –the average house in Knoxville was built around 1951. For older homes, you might want to consider energy-efficient windows such as double-pane windows, which are designed to keep your home cool in the summer and warm in the winter. Wood frames also have a timeless look that's perfect for older homes. For more modern homes, you may want to consider vinyl windows, which are affordable, durable and have a modern look.

You can save money on window installation by choosing a cheaper option like single-hung vinyl windows. These have lower prices compared to more expensive windows such as wood, fiberglass, or double-hung windows.

The process for installing windows typically starts with measuring the old windows and ordering new ones. After that, a professional installer will prep the work area, remove the existing windows, and install the new ones. Once this is done, the installer will trim out the gap and finish by caulking the window.

Yes, many window companies provide financing options. Some installers offer low-interest or no-interest loans based on your income, while other companies offer special financing plans with agreements and conditions that vary depending on the project.

Window replacement companies in Knoxville typically offer a variety of services, including window installation, fixing windows, window maintenance, cleaning, tinting, and weatherproofing.
