- Windows that are hard to close, open, and lock properly due to wear and age.

- Outdated and inefficient window styles that reduce your house's curb appeal.
How To Choose a Window Company
Selecting a window installer with the proper qualifications helps ensure a smooth installation. We review the most important qualities to consider when choosing a qualified provider below.
Experience
Look for highly-regarded local companies with a long track record of experience successfully installing all kinds of windows. These providers are more likely to understand Napa's climate and your requirements. Request references from recent clients to confirm the quality of a company's work.
Certifications
Choose an installer that’s accredited like leading window companies, and that has Fenestration and Glazing Industry Alliance (formerly AAMA) certification. Suitable credentials indicate they've received proper training in installation best practices. Make sure installers are staff rather than subcontractors, and confirm that the technicians assigned to your job have certification.
Reputation
Spend time going through online reviews, checking the Better Business Bureau, and requesting local references. Review customer feedback to confirm that the company regularly provides good workmanship and service. Avoid companies with complaints of shoddy or unfinished work.
Process
A reputable provider will give you a comprehensive project plan, detailed timeline, clear expectations, and an overview of all material and installation options. Avoid providers that offer unclear quotes or timelines. Ask for regular contact throughout the process, so you aren't caught off guard when installation starts.
Warranties
Look for contractors that guarantee their installations and offer warranties on labor and materials. This is a sign of trust in their window installations. Look for unlimited lifetime warranties that can even transfer to new homeowners.
Materials
Verify that your window installer works with trusted, long-lasting brands, offers energy-efficient window options, and fits your budget. Look for window options with design flexibility, enhanced UV protection, and good energy ratings, and check whether the materials include their own manufacturer warranties.
