    How To Choose a Window Company in State College

    An exceptional reputation is essential when it comes to choosing a window company. However, your chosen company should also suit your priorities and appreciate your vision. Consider the following factors during your company search:

    Window Cost by Type

    Replacing your windows is a major purchase, so balancing cost with long life is important. Choosing cheap windows could actually raise your overall cost, since they come with a shorter lifespan and more intensive maintenance needs. The age of your home, in addition to the styles, sizes, and materials of windows you opt for, can impact pricing. Transom windows are inexpensive with their simple size and straightforward form factor, while a custom-cut arch window in a master suite will cost more. An installer can help you with choosing the products that fit your preferences.

    In this table, you can find cost data for the most common residential window types to determine how much you might pay.

    Window TypesAverage Cost
    Glass Block$46-$591

    Window Material Cost

    You'll also need to choose a window material. Homeowners usually choose a material based on aesthetic preferences, the local climate and energy efficiency objectives. Aluminum windows are perfect for sleek, modern designs, but they cost more up-front. You'll pay less for wood windows up-front, but you'll need to invest in regular maintenance to prevent the frame from wear and warping. Vinyl is readily available and tends to cost less, but don't underestimate its strong durability and low maintenance needs.

    Window TypesAverage Cost

    Other Window Replacement Costs

    Ask each installer you're considering about warranty fees, labor costs, and permit fees. This will help you get a clear picture of the total costs involved in the project.

    Experience and Training

    Peruse a company's website and chat with a representative to learn more about its product and service offerings, pricing, and warranties. Many companies also keep online portfolios that highlight past projects.

    Ensure that the company focuses on window replacement. The more dedicated instruction its staff has, and the longer it has been active, the more likely it will provide excellent workmanship.

    Licensing and Credentials

    While Pennsylvania window installers don't need a state license, they must still register with the attorney general's office and follow written contract requirements for residential jobs over $500 in value. Some cities, including Philadelphia, require licensure and have liability insurance standards.

    Types of Windows Offered

    No two installers offer the same window designs and materials. Look for one that's an expert in the type you want for your home.

    • Awning
    • Bay
    • Bow
    • Casement
    • Crank-out
    • Custom
    • Double- or single-hung
    • Egress
    • Garden
    • Jalousie
    • Picture
    • Sliding
    • Skylight
    • Specialty
    • Storm
    • Transom
    • Vent
    Finally, pay close attention to the materials that an installer uses. Each frame material has a different price point, life span and energy efficiency level. A company will usually specify whether the windows they mount use vinyl, metal, composite, wood, or fiberglass.

    Customer Feedback

    Reading other customers' stories is an interesting way to screen window companies in your area. You can find customer reviews on websites like Google, Yelp, Trustpilot, and the BBB. Referrals can also help you in your company search. Ask each company you're interested in for a list of references, and talk to family and friends about who they use for window installations.

    Frequently Asked Questions About Window Replacement in State College

    How could new windows help my energy efficiency?

    State College homeowners could save up to $320 per year by upgrading to efficient windows. They'll also decrease their property's carbon dioxide emissions by 290 pounds per year.

    According to the national Department of Energy, as much as 33% of a house's HVAC usage is to compensate for the heat or cold entering through windows. Efficient windows help keep heat out in the summertime and retain heat in the wintertime, both protecting your comfort and saving you money.

    Are there tax incentives for installing energy-efficient windows?

    Ultimately, the tax incentives you can claim depend on the scope of your window replacement and your city. You can claim up to 30% of the value of new efficient windows as a federal tax credit, up to $3,200 per year, until 2032. We also encourage you to speak with your local building department for more information on financial benefits specific to your area.

    How important are guarantees and extended support packages?

    Window companies often give warranties for the work they do. Each typically covers defects with materials and workmanship for a specified period of time. It's essential to verify the specific terms of the warranty with a window company before you sign a contract.
