- A chilly house and high energy bills from poor window insulation.
- Condensation issues, fogging between window panes, or rotting window frames that allow moisture intrusion into the home.
- Drafts and cold air coming in through old, loose-fitting windows.
- Outdated and inefficient window styles that take away from your house's curb appeal.
How To Choose a Window Company
Hiring an experienced window installation professional contributes to a great experience and excellent results. Below, we outline the main criteria for selecting a qualified window installer.
Experience
Find an established local window company with many years or decades of success installing all window types. Seasoned providers are more likely to be able to seamlessly accommodate Foster City's climate and local homeowner needs. To confirm a company deliver quality work, request references from recent customers.
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. Suitable credentials show that a contractor is trained in window installation best practices. Confirm that installers are staff, not subcontractors, and check that the technicians working on your project are certified.
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 regularly provides good workmanship and service. Steer clear of companies with complaints of poor or incomplete work.
Process
A good window installer will be able to provide a comprehensive project plan, reasonable timelines, clear expectations, and an overview of all material and installation options. Avoid companies that provide ambiguous quotes or schedules. Insist on consistent contact from the beginning to avoid surprises further into the project.
Warranties
Seek out window firms that offer assurances on their installations, and that offer warranties on products and labor. This demonstrates faith in their work. Also seek out unlimited lifetime warranties that can transfer to new homeowners.
Materials
Verify that your window company works with long-lasting, durable brands, offers energy-efficient window options, and fits your budget. Look for window options with good energy ratings, enhanced UV protection, and design flexibility. Check whether the materials include their own manufacturer warranties.
