How To Choose a Window Company

Choosing a window installer with appropriate qualifications helps ensure a smooth installation. We review the most important qualities to consider when selecting a qualified provider below.

Experience

Make sure you select a seasoned local installer with a proven track record of successfully installing and replacing windows. Providers that have served Kingsport 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. Proper certification shows that a provider has gotten proper training in installation best practices. Ensure installers are employees rather than subcontractors, and verify that the technicians working on your home hold the right certifications.

Reputation

Spend time reviewing online feedback, checking the Better Business Bureau, and requesting local references. Review customer feedback to verify that a company consistently does quality work and provides good service. Avoid companies with complaints of shoddy work or unfinished jobs.

Process

A quality 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 unclear quotes or schedules. Ask for consistent contact through the whole process to avoid surprises once installation is underway.

Warranties

Look into window installers that provide installation guarantees on materials and labor. This demonstrates confidence in their work. Target companies with unlimited lifetime warranties that can transfer to new homeowners.

Materials

Verify that your window provider works with trusted, long-lasting brands, offers power-saving window options, and fits your budget. Look for window options with design flexibility, good energy ratings, and enhanced UV protection, and check whether the materials include their own manufacturer warranties.
