How To Choose a Window Company in Pomona

With Pomona's sheer size, you're sure to find a trustworthy replacement window company that suits your values and preferences. As you contact companies, keep the following factors in mind:

Window Cost by Type

Replacing your windows is a major investment, so balancing cost with quality is vital. Choosing cheap windows could actually raise your overall cost, due to their reduced lifespan and more intensive maintenance needs. The size, style, and material of your replacement windows are the most significant factors in your final cost. Transom windows are inexpensive with their simple size and straightforward form factor, while new skylights cost more to prepare for and install. It's advisable to speak with a trusted window installer to decide on 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 TypesAverage Cost
Glass Block$48-$609

Window Material Cost

You'll also need to pick a window material. Homeowners usually base their decision on aesthetic preferences, energy efficiency objectives and the local climate. Aluminum windows are perfect for sleek, modern designs, but they cost more up-front. You'll pay less for wood windows 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 take into account the cost of installation, warranties, and any other additional costs that your project may need.

Experience and Training

Choose a provider that focuses on window replacement and installation, and look for this information on its website:

  • How many years it's been operating
  • Photo galleries of projects its crews completed
  • Private accreditations attesting to its workmanship
The more experience a company has, the better its service and workmanship.

Licensing and Credentials

A California window company must be licensed as a Window Coverings Contractor, Glazing Contractor and General Building 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

No two window companies offer the same window styles and materials. Look for one that's an expert in the type you want for your home.

Finally, pay close attention to the materials that an installer uses. Each window frame material has a different life span, energy efficiency level and price point. A company will usually specify whether the windows they place use wood, vinyl, fiberglass, metal, or composite.

Customer Feedback

Reading other customers' stories is an excellent way to screen different window replacement companies. Trustworthy sources for customer reviews include Trustpilot, Google, and Yelp 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 Pomona

What are the benefits of hiring a window installer?

By working with 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 skills to do the job safely and precisely. You can also get fast, informed answers to your questions and customized help to maximize your new windows' potential.

I've heard there are tax credits for energy-efficient windows. How much could I save?

Yes. No matter where you're located, you can claim a federal tax credit of up to $3,200 per year on up to 30% of your window replacement's cost. Additionally, most state and some local governments offer tax breaks of their own. We recommend consulting your local government for specific information about tax incentives available in your area.

How can I gauge the quality of a replacement window?

One of the first metrics you'll encounter when looking at a replacement window is its U-factor. The lower this number, the better the window is at blocking extreme heat and cold from entering your home. Other numbers to look at include:
  • "visible transmittance," which measures how much light can pass through the window
  • "solar heat gain coefficient," which measures 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 measures how easy it is for air drafts to occur (the lower the number, the better)
