- Inefficient and outdated window styles that detract from your house's curb appeal.

- Condensation issues, fogging between window panes, or rotting window frames allowing moisture intrusion into the home.
How To Choose a Window Company
Selecting a window installer with the right qualifications helps ensure a smooth installation. We cover the most important considerations for selecting a qualified provider below.
Experience
Seek out an established local window company with a proven track record of success installing all types of windows. Seasoned providers are more likely to have an in-depth knowledge of Alton's climate and local homeowner requirements. To verify a provider's reputation, request references from recent customers.
Certifications
Look for installers that are backed by leading 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 been appropriately trained in installation best practices. Ensure installers are employees rather than subcontractors, and verify that the technicians assigned to your job hold the right certifications.
Reputation
Read through online feedback from past clients, check the Better Business Bureau (BBB), and request local references. Review customer feedback to confirm that the contractor consistently provides quality work and good customer service. Avoid companies that have complaints of shoddy work or unfinished jobs.
Process
A good window installer will be able to provide a detailed project plan, precise timelines, clear expectations, and an overview of all material and installation options. Avoid companies that provide unclear quotes or schedules. Ask for continual contact from the beginning to avoid surprises later on.
Warranties
Research contractors that guarantee their installations and provide warranties on labor and materials. This is a sign of confidence in their window installations. Look for unlimited lifetime warranties that can even be transferred to new homeowners.
Materials
Make sure the window company offers durable, long-lasting window options and top energy-saving window brands within your budget. Look for design flexibility, enhanced UV protection, and good energy ratings. Check that the window materials also have manufacturer warranties.
