When To Replace Windows

Installing new energy-efficient windows can substantially boost your home's value, noise reduction, appearance, comfort, and insulation. Some clear indicators it's time for new windows include the following:

  • Cold air and drafts coming in from old, loose-fitting windows.
  • Condensation issues, fogging between window panes, or rotting window frames letting in moisture.

How To Choose a Window Company

Choosing a window installer with the right qualifications helps ensure a smooth installation. We review the most important considerations for choosing a qualified company below.

Experience

Look for well-established local companies with a long track record of experience successfully installing all kinds of windows. These providers are more likely to have a deep knowledge of Dover's climate and local homeowner needs. Ask for references from recent clients to verify quality and experience.

Certifications

Choose companies that have certifications from leading window brands, and that have Fenestration and Glazing Industry Alliance (formerly AAMA) certification. Having certification shows they've received proper training in installation best practices. Make sure installers are staff, not subcontractors, and confirm the technicians doing your job are certified.

Reputation

Spend time looking through online reviews, checking the Better Business Bureau, and asking for local references. Review customer feedback to verify that the company regularly provides good workmanship and service. Avoid companies with complaints of shoddy work.

Process

The most experienced window installation providers will supply a comprehensive project plan and schedule, clear expectations, and an overview of product and installation options. Avoid companies that offer vague quotes or timelines that lack necessary details. Look for continual contact throughout to avoid surprises later on.

Warranties

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

Materials

Ensure your provider uses durable, energy-efficient window brands that fit your budget. Look for design flexibility, enhanced UV protection, and good energy ratings. Confirm the window materials come with their own manufacturer warranties as well.

Frequently Asked Questions About Window in Dover, DE
