When To Replace Windows
Replacing your current windows with new energy-efficient ones can greatly boost your home's comfort, insulation, noise reduction, appearance, and value. Clear indicators it's time to invest in new windows include:
- Cold air and drafts leaking in from old, loose-fitting windows.
- Fogging between window panes, condensation issues, or rotting window frames allowing moisture intrusion into the home.
- Windows that are hard to open, close, and lock properly due to wear and age.
- Inefficient and outdated window styles that reduce your house's curb appeal.
- A chilly house and high energy bills from poor insulation around windows.
How To Choose a Window Company
Hiring a qualified windows installation contractor is the key to a successful project. Below, we cover the main factors to consider when making your selection.
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 Islip's climate and your requirements. Request references from recent clients to confirm the quality of a company's work.
Certifications
Choose an installer that’s accredited like major window manufacturers, and that has Fenestration and Glazing Industry Alliance (formerly AAMA) certification. Proper certification shows they've received proper training in installation best practices. Verify that installers are staff rather than subcontractors, and confirm that the technicians assigned to your job have certification.
Reputation
Spend time reading through online reviews, checking the Better Business Bureau (BBB), and asking for local references. Review customer feedback to verify that a company regularly provides good workmanship and customer service. Avoid companies with complaints of shoddy or unfinished work.
Process
The best window installers will supply a detailed project plan and schedule, clear expectations, and an overview of product and installation options. Avoid companies that offer ill-defined quotes or timelines that lack necessary details. Look for ongoing contact throughout the process to avoid surprises later in the project.
Warranties
Research window installers that back their installations with guarantees and provide warranties on labor and materials. This demonstrates confidence in their work. Opt for companies with unlimited lifetime warranties that can be transferred to new homeowners.
Materials
Verify that your window company works with long-lasting, durable brands, offers power-saving window options, and fits your budget. Look for window options with enhanced UV protection, design flexibility, and good energy ratings, and check whether the materials include their own manufacturer warranties.
