How To Choose a Window Company in Gilroy

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

Window Cost by Type

Replacing your windows is a substantial investment, so balancing cost with value is important. Although high-quality replacement windows may be more expensive to buy, they often yield better long-term value due to their longer lifespan. The material, style, and size of your replacement windows are the most significant factors in your final cost. Simple double-hung windows deliver great value with their straightforward style and simple mechanisms, while a sweeping, custom-size picture window will cost more. A professional can help you with choosing the solutions that fit your needs.

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
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

Materials also help determine a window's cost. You might pick a material based on your desired look, the local climate, and your energy efficiency goals. For example, wood windows can give your home an organic design without breaking the bank, but you'll have to invest more toward maintenance. Aluminum and composite windows cost more up-front, but they're incredibly durable against the elements, so you'll spend far less on maintenance.

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

Other Window Replacement Costs

Ask each contractor you're evaluating 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 installer has been operating, the better its workmanship will likely be. Call a company representative to learn more about its guarantees, experience, and public and private credentials. Company websites often keep photo galleries where you can see previous work technicians have done.

Licensing and Credentials

A California window provider must be licensed as a General Building Contractor, Glazing 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 steep fines.

Types of Windows Offered

The type of window you prefer should play a role in your company choice. Not every installation crew will necessarily be familiar with the window brand you want. A company website will show more about the window types it focuses on, such as:

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

Customer Feedback

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

Frequently Asked Questions About Window Replacement in Gilroy

What are the benefits of hiring a window installer?

Window replacement is a substantial purchase 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 warranty that addresses required maintenance and most needed fixes.

How can I fix a rotting or molding window frame?

Mold tend to set in due to moisture issues or water damage. Fortunately, you may not need to replace your windows to solve this annoying and unsightly issue. A window company can remove the mold, restore the affected area, and reset the tight seal your windows need to work at their healthiest.

How can I gauge the quality of a replacement window?

You can assess the quality of a replacement window by looking at some key numbers, including the following:
  • Air leakage rating, which indicates how tight a window's seal is
  • Condensation resistance, which shows how a window manages moisture
  • U-factor, which measures a window's insulating capability
  • Visible transmittance, which measures how much light passes through a window
  • Solar heat gain coefficient, which determines how much heat from sunlight can pass through the window
