How To Choose a Window Company

Choosing a window installer with the right qualifications helps ensure a smooth installation. We explain the main factors to consider when selecting a qualified company below.

Experience

Make sure you select a seasoned local installer with a proven track record of successfully installing and replacing windows. Companies that have served Westmont for years are more likely to have a deep knowledge of the local climate and local homeowners' needs. Get references from recent clients to learn more about a provider’s service.

Certifications

Select an installer that is accredited by leading window companies and associations like the Fenestration and Glazing Industry Alliance, formerly known as the AMMA. Appropriate accreditation means that a contractor is trained in best practices for installation. Confirm that installers are staff, not subcontracted workers, and verify that any technicians working on your project are certified.

Reputation

Read through online reviews, check the Better Business Bureau (BBB), and request local references. Review customer feedback to make sure that the contractor consistently provides quality work and good customer service. Avoid companies that have complaints of shoddy work or unfinished jobs.

Process

A quality window installer will be able to provide a comprehensive project plan, precise timelines, clear expectations, and an overview of all material and installation options. Avoid companies that provide vague quotes or schedules. Look for regular contact throughout to avoid surprises later on.

Warranties

Seek out companies that back their work with guarantees and offer warranties on products and labor. This demonstrates trust in their window installations. Look for unlimited lifetime warranties that can even transfer to new homeowners.

Materials

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