  • Condensation issues, fogging between window panes, or rotting window frames allowing moisture intrusion into the home.

  • Inefficient and outdated window styles that detract from your house's curb appeal.
  • High energy bills and discomfort due to poor insulation.
  • Windows that are hard to open, close, or lock properly due to wear and age.

How To Choose a Window Company

Finding a truly qualified windows installation contractor is critical to a successful project. Below, we cover the most important considerations when it comes to making your selection.

Experience

Make sure you select an experienced local installer with a long record of successfully installing and replacing windows. Companies that have served Mount Pleasant for years are more likely to have a deep knowledge of the local climate and local homeowners' needs. Get references from recent clients to confirm a company provides quality installations.

Certifications

Look for installers that are backed by major window manufacturers and accredited by top industry associations, including the Fenestration and Glazing Industry Alliance, formerly known as the AAMA. Appropriate credentials mean that a provider has received suitable training in installation best practices. Ensure installers are employees rather than subcontractors. Verify that any technicians assigned to your job hold the right certifications.

Reputation

Spend time reading 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. Steer clear of companies with complaints of shoddy or unfinished work.

Process

The most qualified company will take time to provide you with a detailed project plan, timeline, expectations, and reviews of all material and installation options. Beware of vague quotes or timelines that don't provide enough specifics upfront. Look for continual communication throughout the process to avoid surprises down the road.

Warranties

Look into window installers that offer guarantees on labor and materials. This demonstrates confidence in their work. Seek out companies with unlimited lifetime warranties that can pass to new homeowners.

Materials

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