When To Replace Windows

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

  • Condensation issues, fogging between window panes, or rotting window frames letting in moisture.
  • High energy bills and a chilly house due to poor insulation.
  • Inefficient and outdated window styles that detract from your house's curb appeal.
  • Windows that are hard to open, close, or lock properly due to age and wear.
  • Cold air and drafts coming in from old, loose-fitting windows.

How To Choose a Window Company

For a successful window replacement, you need to hire an installer with proven expertise. Below, we go over the most important qualifications for selecting a window installer.

Experience

Look for well-established local installers with lots of experience. Installers that have been installing windows locally for many years are more likely to know the local climate and how to best meet your needs. Ask for references from recent customers to verify that a provider delivers quality work.

Certifications

Choose companies that have certifications from top window brands, and that have Fenestration and Glazing Industry Alliance (formerly AAMA) certification. Certification means they've been properly trained in installation best practices. Make sure installers are staff rather than subcontractors, and confirm that any technicians working on your home are certified.

Reputation

Spend time reading through online reviews, checking the Better Business Bureau (BBB), and asking for local references. Review customer feedback to confirm that a company consistently does quality work and provides good service. Avoid companies with complaints of shoddy or unfinished work.

Process

A reputable window installer will be able to provide a comprehensive project plan, reasonable timelines, clear expectations, and an overview of all material and installation options. Avoid companies that provide vague quotes or schedules. Ask for consistent contact throughout to avoid surprises further into the project.

Warranties

Research window firms that provide guarantees on their work, and that offer warranties on products and labor. This shows confidence in their work. Also look for unlimited lifetime warranties that can transfer to new homeowners.

Materials

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