When To Replace Windows

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

  • Condensation issues, fogging between window panes, or rotting window frames that let in moisture.

  • Cold air and drafts coming in through old, loose-fitting windows.

  • High energy bills and a chilly house from poor window insulation.

How To Choose a Window Company

Hiring a qualified windows installation contractor is critical to a successful project. Below, you'll learn the main factors to consider when making your selection.

Experience

Make sure you select 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

Choose an installer that’s accredited like major window manufacturers, and that has Fenestration and Glazing Industry Alliance (formerly AAMA) certification. Proper certification shows they've received appropriate instruction in installation best practices. Verify that installers are staff, not subcontracted laborers, and confirm that any technicians working on your home have certification.

Reputation

Spend time reviewing online feedback, checking the Better Business Bureau, and requesting local references. Review customer feedback to confirm that a company delivers consistent quality workmanship and great service. Avoid companies with complaints of shoddy work or unfinished jobs.

Process

The best window installers will supply a detailed project plan and schedule, clear expectations, and an overview of all material and installation options. Avoid companies that offer vague quotes or timelines that lack necessary details. Look for regular contact throughout the process to avoid surprises later on.

Warranties

Look for window installers that guarantee their work and provide warranties on materials and labor. This is a sign of expert workmanship. Choose companies with unlimited lifetime warranties that can be transferred to new homeowners.

Materials

Ensure that a company uses durable, energy-efficient window brands that fit your budget. Look for good energy ratings, design flexibility, and enhanced UV protection. Confirm the window materials have their own manufacturer warranties as well.
