How To Choose a Window Company in Union City

It's essential to find a window replacement company that aligns with your unique values, needs, and preferences. Consider the following traits during your search:

Window Cost by Type

When it comes to replacing your windows, value is paramount. Each window you buy should offer unparalleled durability at a fair price point. Although top-of-the-line replacement windows may be more expensive to buy, they often provide better long-term value due to their increased lifespan. The material, size, and style of your replacement windows have the greatest impact on your final cost. Single-hung windows often cost less due to their straightforward style and simple mechanisms, while new skylights cost more to prepare for and install. It's advisable to speak with a trusted window installer to figure out your ideal options.

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

Experience and Training

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

  • How long it's been serving the Union City area
  • Photo galleries of projects its crews completed
  • Official non-government 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 Glazing Contractor, General Building Contractor and Window Coverings Contractor if it takes on jobs valued at over $500. Each certification has its own exam and work requirements. If a contractor is caught working without a license, they'll have to pay hefty penalties.

Types of Windows Offered

The kind of window you desire should play a role in your company choice. Not every installer will necessarily be familiar with the window brand you want. A company website will provide more about the kinds of windows it focuses on, such as:

Also, check the kind of window framing materials a company works with. Each material has varying price points, life spans, and energy performance capabilities. Common materials include fiberglass, wood, vinyl, aluminum and composite.

Customer Feedback

Reading other customers' stories is a surefire way to screen different window replacement companies. Trustworthy sources for customer reviews include the BBB, Yelp, and Trustpilot Speak with people you know who have used a company you're interested in, and ask a representative for a copy of its reference list.

Frequently Asked Questions About Window Replacement in Union City

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

In Union City specifically, most homeowners using efficient windows lower their carbon emissions by 120 pounds annually. This means they save $530 on their annual electricity costs.

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 installing new, more efficient windows, you can boost your home's energy efficiency and minimize your electricity bills.

How frequently should I upgrade or replace my windows?

Windows don't have an indefinite lifespan, and most wood models are built to serve your home for 15–20 years. Over time, sealants loosen, framing contracts and expands, and window coatings fade. These changes result in energy loss, air leaks, condensation, and other expensive problems necessitating repair or replacement.

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

The answer to this question is primarily influenced by your finances, how your windows are doing overall, and your long-term home improvement goals. A full-window replacement can improve your home's insulation and increase your home's resale value, while replacing windows gradually can protect your budget and directs your focus to the windows in the worst condition. Ultimately, it's important to consider the benefits and drawbacks and select the approach that works best for your situation.
