How To Choose a Window Company
For a successful window replacement, you want to find an installation contractor with proven expertise. Below, we cover the most important qualifications for selecting a window installer.
Experience
Look for reputable local companies with many years, ideally decades, of experience successfully installing all types of windows. These providers are more likely to understand Berkeley's climate and your requirements. Ask for references from recent clients to confirm the quality of a company's work.
Certifications
Look for installers that are backed by major window manufacturers and certified by leading industry groups, including the Fenestration and Glazing Industry Alliance, formerly known as the AAMA. Appropriate accreditation indicates that a provider has gotten proper training in quality installation methods. Ensure installers are employees, not subcontractors, and verify that any technicians assigned to your job hold the right certifications.
Reputation
Take time to read online reviews, check the Better Business Bureau (BBB), and request local references. Review customer feedback to verify that the company consistently delivers good workmanship and service. Steer clear of companies with complaints of shoddy work.
Process
The highest-quality window installation providers will supply a detailed project plan and schedule, clear expectations, and an overview of material and installation options. Avoid companies that offer unclear quotes or timelines that don't provide specifics upfront. Look for regular contact throughout to avoid surprises once work gets underway.
Warranties
Search for window installers that offer guarantees on materials and labor. This shows confidence in their work. Target companies with unlimited lifetime warranties that can transfer to new homeowners.
Materials
Ensure that a company uses durable, energy-efficient window brands that fit your budget. Look for design flexibility, enhanced UV protection, and good energy ratings. Confirm the window materials come with their own manufacturer warranties as well.
