How To Choose a Window Company
Hiring a qualified windows installation contractor is the key to a successful project. Below, you'll learn the main factors to consider when making your selection.
Experience
Find well-established local installers with extensive experience. Installers that have worked in Lake St. Louis for years are more likely to know the local climate and how to best meet your needs. Ask for references from recent customers to confirm a company’s reputation.
Certifications
Look for installers that are backed by top window manufacturers and certified by leading industry groups, including the Fenestration and Glazing Industry Alliance, formerly known as the AAMA. Appropriate credentials mean that a provider has been appropriately trained in installation best practices. Ensure installers are employees, not subcontractors, and verify that any technicians working on your home have the right certifications.
Reputation
Spend time going through online reviews, verifying with the Better Business Bureau (BBB), and asking for local references. Review customer feedback to confirm that the company delivers consistent quality workmanship and great service. Avoid companies with complaints of shoddy work or unfinished jobs.
Process
The best window installers will supply a comprehensive 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 continual contact throughout to avoid surprises later in the project.
Warranties
Look for window companies that back their installations with guarantees, and that provide warranties on products and labor. This indicates faith in their work. Also seek out unlimited lifetime warranties that can be transferred to new homeowners.
Materials
Make sure the window company offers windows that are built to last and top energy-saving window brands that fit your budget. Look for design flexibility, enhanced UV protection, and good energy ratings. Check that the window materials also have manufacturer warranties.
