How To Choose a Window Company in Cupertino

It's important to find a window installer that matches your individual values, needs, and preferences. Consider the following areas during your search:

Window Cost by Type

When you're shopping for new windows, it's essential to remember that there's more to cost than just purchase price. You want a window with top-notch quality and durability. Choosing cheap windows could actually increase your overall cost, since they come with a reduced lifespan and more intensive maintenance needs. The age of your home, in addition to the materials, styles, and sizes of windows you opt for, can impact pricing. Single-hung windows often cost less due to their straightforward style and simple mechanisms, while a sweeping, custom-size picture window will cost more. It's wise to speak with a reliable installer to figure out your ideal options.

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$53-$680

Window Material Cost

You'll also need to select a window material. Homeowners frequently choose a material based on the local climate, energy efficiency objectives and aesthetic preferences. 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 warping and wear. 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

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, warranties, and any other supplemental fees that your project may require.

Experience and Training

The longer a window company has been operating, the better its workmanship will likely be. Talk with a company representative to learn more about its guarantees, public and private credentials, and experience. Company websites often have photo galleries showcasing previous work technicians have done.

Licensing and Credentials

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

Types of Windows Offered

No two installers offer the same window styles and materials. Find one that focuses on 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 a provider uses. Each frame material has a different life span, energy efficiency level and price point. A company will usually specify whether the windows they mount use composite, vinyl, wood, metal, or fiberglass.

Customer Feedback

Reading other customers' stories is a surefire way to screen window companies in your area. Trustworthy sources for customer reviews include the BBB, Trustpilot, and Yelp Speak with people you know who have used the company you're evaluating, and ask a representative for professional references.

Frequently Asked Questions About Window Replacement in Cupertino

What are the benefits of hiring a window installer?

Window replacement is a substantial expense that greatly impacts your home's comfort and energy efficiency. Hiring a professional window company to oversee your project ensures your windows will be properly installed, perform efficiently, and be properly insulated. Companies also typically include a guarantee that takes care of required maintenance and most future repairs.

Does window replacement involve pulling permits?

Replacing windows may involve securing permits, based on your local building codes and regulations. Some communities mandate permits for window replacement projects when they involve structural changes or alterations to the window openings. We recommend checking with your local building department or consult a professional before proceeding with any window replacement work.

What's the typical timeline for a professional window replacement?

The length of a window replacement project can vary greatly. It usually takes up to a month for the contractor to receive your windows from the manufacturer. The installation process itself often takes 40–60 minutes per window. However, larger windows or more complex installations may require additional time.
