How To Choose a Window Company in Fontana

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

Window Cost by Type

Replacing your windows is a significant investment, so balancing cost with value is important. Choosing budget windows could actually raise your overall cost, since they come with a shorter lifespan and more intensive maintenance needs. The age of your home, as well as the styles, materials, and sizes of windows you select, can impact pricing. 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. A professional can help you with 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
Glass Block$44-$561

Window Material Cost

You'll also need to select a window material. Homeowners often choose a material based on energy efficiency objectives, aesthetic preferences and the local climate. Aluminum windows are perfect for sleek, modern designs, but they cost more up-front. Wood windows cost less 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 company you're considering about labor costs, warranty fees, and permit fees. This will help you gain a complete understanding of the total costs involved in the project.

Experience and Training

The longer a window provider has been in business, the better its workmanship will likely be. Call a company representative to learn more about its public and private credentials, guarantees, and experience. Company websites often keep photo galleries demonstrating previous work technicians have done.

Licensing and Credentials

A California window installer must be licensed as a Window Coverings Contractor, Glazing Contractor and General Building Contractor if it takes on 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 steep fines.

Types of Windows Offered

There are a variety of replacement window types you can choose from, and it's vital to find a company that is experienced with 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
Finally, pay close attention to the materials that a company uses. Each frame material has a different life span, price point and energy efficiency level. A company will usually specify whether the windows they mount use wood, fiberglass, metal, vinyl, or composite.

Customer Feedback

Perhaps the best way to screen window companies for your job is to check what previous customers have said about them. Trustworthy sources for customer reviews include Google, 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 Fontana

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

In Fontana specifically, most homeowners using efficient windows cut their carbon emissions by 120 pounds annually. That amounts to $540 of annual savings.

The U.S. Department of Energy states that 25%–30% of a home's heating and cooling capacity is used to compensate for heat gain and heat loss through windows. By upgrading to new, more efficient windows, you can enhance your home's energy efficiency and lower your electricity bills.

How frequently should I upgrade or replace my windows?

Refer to your product warranty to best understand how long your windows are meant to last. Most home windows have life spans of 15–20 years. Check your windows for damage, leaking, and poor performance to determine whether your windows should be replaced.

What repair services do window companies offer?

Many window companies repair screens, glass, window seals, frames, and mechanisms
