How To Choose a Window Company in Union City

Trustworthiness is important when it comes to choosing a window installer. However, your chosen company should also suit your needs and respect your vision. Think about the following factors during your company search:

Window Cost by Type

Replacing your windows is a substantial investment, so balancing cost with durability is vital. Although high-quality windows may be more expensive to buy, they often provide better long-term value due to their extended lifespan. The style, size, and material of your new windows play the largest role in determining your final cost. Simple double-hung windows deliver great value with their straightforward style and simple mechanisms, while a sweeping, custom-size picture window will cost more. An installer can guide you through choosing the options that fit your requirements.

This table shows average prices for various window types to give you an idea of what to expect.

Window TypesAverage Cost
Arched$255-$1569
Awning$370-$1030
Bay$852-$6323
Custom$379-$1053
Casement$295-$1709
Double-hung$137-$889
Egress$252-$631
Glass Block$50-$639
Picture$222-$1639
Single-hung$100-$1686
Skylight$126-$1522
Sliding$290-$1475
Storm$59-$416
Transom$309-$646

Window Material Cost

Window prices also vary based on material. Each option provides unique advantages depending on the local climate and energy-saving goals. Fiberglass and vinyl are readily-available materials, so they tend to cost less. Likewise, composites and aluminum look sleek and stay strong against the elements, so they tend to cost more.

Window TypesAverage Cost
Aluminum$59-$1686
Composite$608-$1367
Fiberglass$100-$852
Vinyl$205-$1897
Wood$304-$1709

Other Window Replacement Costs

Your total cost for new windows will also include warranty fees (if applicable), permit-related costs (if required), and labor. Make sure to discuss each of these elements with a sales representative before committing to a window company.

Experience and Training

Browse a company's website and talk to a representative to learn more about its product and service offerings, pricing, and warranties. Many companies also keep online galleries that showcase past projects.

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

Licensing and Credentials

A California window provider must be licensed as a Window Coverings Contractor, General Building Contractor and Glazing Contractor if it takes on jobs valued at over $500. Each certification has its own test and work requirements. If a contractor is caught working without a license, they'll have to pay steep fines.

Types of Windows Offered

There are numerous replacement window types you can choose from, and it's vital to find a company that focuses on installing the ones you want. Check 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
Also, check the type of window framing materials a company works with. Each material has distinct price points, life spans, and energy performance capabilities. Common materials include aluminum, wood, vinyl, composite and fiberglass.

Customer Feedback

Reading other customers' stories is a surefire way to screen window companies in your area. Read customer reviews on sites such as Trustpilot, Google, and Yelp. You can also view customer reviews and company ratings on the Better Business Bureau (BBB) website. Talk to people you know who have used the company you're interested in, and ask a representative for professional references.

Frequently Asked Questions About Window Replacement in Union City

How could new windows help my energy efficiency?

Union City homeowners could save up to $530 each year by installing efficient windows. They'll also lower their property's carbon dioxide emissions by 120 pounds per year.

According to the federal 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.

What is the maintenance schedule for an average window, and how long will it last?

Refer to your product warranty to best understand how long your windows are meant to last. Most residential windows are built to serve 15–20 years. Check your windows for damage, leaks, and poor performance to determine whether you need a replacement.

Is it better to replace all my windows at once, or just a few at a time?

To form a window replacement approach, consider your financial situation, home improvement goals, and energy savings targets. A phased replacement helps you save money and prioritize the windows that need the most attention, but you'll also notice lesser improvements in efficiency. A entire-home replacement will be more expensive up front, but you'll see a more significant energy efficiency improvement.
