How To Choose a Window Company in Gilroy

Trustworthiness is key when it comes to choosing a window installer. However, your chosen company should also align with your priorities and respect your vision. Consider the following factors during your company search:

Window Cost by Type

When it comes to upgrading your windows, cost-effectiveness is most important. Each window you purchase should deliver top-notch durability at a fair price point. Choosing cheap windows could actually raise your overall cost, since they come with a shorter lifespan and more intensive maintenance needs. The final cost of your window replacement will depend on the particular materials, styles, and sizes you need. Single-hung windows often cost less due to their straightforward style and simple mechanisms, while a custom-cut arch window in a master suite will cost more. It's recommended to speak with a reliable installer to determine your best options.

In this 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 $271-$1667
Awning $393-$1095
Bay $906-$6721
Custom $403-$1120
Casement $313-$1817
Double-hung $146-$945
Egress $268-$671
Glass Block $53-$680
Picture $235-$1742
Single-hung $106-$1792
Skylight $134-$1618
Sliding $308-$1568
Storm $63-$443
Transom $328-$687

Window Material Cost

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

Window Types Average Cost
Aluminum $63-$1792
Composite $647-$1453
Fiberglass $106-$906
Vinyl $218-$2016
Wood $323-$1817

Other Window Replacement Costs

Your contractor will factor the price for your windows and the value of their services into its total estimate. Make sure to factor in the cost of installation, guarantees, and any other supplemental fees that your project may need.

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 portfolios that exhibit past projects.

Ensure that the company specializes in window replacement. The more specific training its staff has, and the longer it has been active, the more likely it will deliver high-quality service.

Licensing and Credentials

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

Types of Windows Offered

There are a variety of replacement window types you can choose from, and it's essential 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 kind of window framing materials a company works with. Each material has distinct price points, life spans, and energy performance capabilities. Common materials include composite, aluminum, vinyl, wood and fiberglass.

Customer Feedback

Perhaps the best way to evaluate window companies for your job is to find out what previous customers have said about them. Trustworthy sources for customer reviews include Yelp, Google, and the BBB Talk to people you know who have used the company you'd like to hire, and ask a representative for professional references.

Frequently Asked Questions About Window Replacement in Gilroy

What are the benefits of hiring a window installer?

By hiring a professional, you don't need to worry about measurement missteps or lacking the right tools. A window installation crew is well-equipped with the right tools and knowledge to do the job safely and precisely. You can also get fast, informed answers to your questions and personalized assistance to make the most of your new windows

How can I fix a rotting or molding window frame?

A molding or rotting window frame is usually a moisture issue. You likely won't have to replace the entire window. Instead, a simple framing job could do. It's best to consult a window expert to ensure adequate sealing and weatherproofing.

What are some important metrics to know when I shop for replacement windows?

One of the first metrics you'll notice when looking at a replacement window is its U-factor. The lower this number, the better the window is at preventing extreme cold and heat from entering your home. Other numbers to consider include:
  • "visible transmittance," which indicates how much light passes through the window
  • "solar heat gain coefficient," which shows how much UV light the window absorbs and releases as heat
  • "Condensation resistance," which determines how well a window can resist moisture (the higher the number, the better)
  • "Air leakage," which evaluates how easy it is for air drafts to occur (the lower the number, the better)
