How To Choose a Window Company in Amherst

Each window company has varying offerings and approaches. To ease the company search, keep these factors in mind:

  • Window Cost

    Replacing your windows is a substantial expense, so balancing cost with quality is vital. Although high-quality windows may cost more upfront, they often provide better long-term value due to their longer lifespan. The types, sizes, and materials of your new windows are the most significant factors in your final cost. An installer can help you with picking the options that fit your needs.

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

    Window Types

    Average Cost

    Arched $219-$1343
    Awning $316-$882
    Bay $730-$5414
    Custom $324-$902
    Casement $252-$1464
    Double-hung $117-$762
    Egress $216-$540
    Glass Block $43-$547
    Picture $190-$1403
    Single-hung $85-$1443
    Skylight $108-$1303
    Sliding $248-$1263
    Storm $51-$356
    Transom $264-$553

  • Window Material Cost

    Materials also help determine a window's cost. You might choose a material based on your energy efficiency goals, the Amherst climate and your aesthetic preferences. The table below showcases the cost differences between the most common materials: Finally, ask each installer you're evaluating about labor costs, warranty fees, and permit fees. This will help you get a clear picture of of the overall expenses involved in the project.

    Window Types

    Average Cost

    Aluminum $51-$1443
    Composite $521-$1171
    Fiberglass $85-$730
    Vinyl $175-$1624
    Wood $260-$1464
  • Experience and Training

    Browse 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 photo galleries that highlight past projects.

    Ensure that the company specializes in window replacement. The more specific training its staff has, and the longer it has been in operation, the more likely it will provide excellent craftsmanship.

  • Licensing and Credentials

    New York's state government doesn't issue contracting licenses for window installers, but this hasn't stopped local governments from taking charge and creating their own licenses. For example, to put in windows in New York City, a company must obtain a Home Improvement Contractor License by passing exams and environmental audits.

  • Types of Windows Offered

    There are numerous replacement window types you can choose from, and it's vital to find a company that has expertise with the ones you want. Look on a company's website and reviews for any of these types:

    • 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 a provider uses. Each frame material has a different price point, energy efficiency level and life span. A company will usually specify whether the windows they place use fiberglass, metal, vinyl, composite, or wood.

  • Customer Feedback

    One of the easiest ways to evaluate a company is to see what other customers have written about their experiences. You can find customer reviews on websites like Yelp, Trustpilot, the BBB, and Google. Speak with people you know who have used the professional you're thinking of hiring, and ask a representative for professional references.

Amherst Window FAQ

How much energy and money will I save by upgrading my windows?

Amherst homeowners could save up to $370 per year by upgrading to efficient windows. They'll also reduce their property's carbon dioxide emissions by 65 pounds per year.

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

What time of year should I replace my windows?

With Amherst's chilly and snowy winters, it's best to schedule your window replacement for the warmer months. You might also choose to replace your windows in the autumn, when costs may be lower.

Should I replace my windows a couple at a time, or is it more economical to replace them all at once?

To form a window replacement game plan, consider your finances, home improvement goals, and energy savings targets. A step-by-step replacement allows for cost savings and prioritize the windows that need the most attention, but you'll also notice smaller gains in efficiency. A whole-home replacement will be more expensive up front, but you'll see a more dramatic energy efficiency improvement.
