How To Choose a Window Company in Castro Valley

An exceptional reputation is important when it comes to choosing a window company. However, your chosen company should also match your needs and appreciate your vision. Think about the following factors during your company search:

Window Cost by Type

When you're shopping for new windows, it's important to remember that there's more to cost than just purchase price. You want a high-quality and durable window. Although high-quality windows may be more expensive to buy, they often provide better long-term value due to their longer lifespan. The style, size, and material of your replacement windows have the greatest impact on 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. If you're unsure, a window specialist can help you decide which options are ideal for your home.

To help you form a rough estimate, this table shows the typical cost of the most common residential window types.

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

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, windows made of wood 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$59-$1686
Composite$608-$1367
Fiberglass$100-$852
Vinyl$205-$1897
Wood$304-$1709

Other Window Replacement Costs

Your total cost for window replacement will also include applicable warranty fees, permit application fees, and labor. Make sure to discuss each of these factors with a sales representative before committing to a window company.

Experience and Training

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

  • How long it's been serving the Castro Valley area
  • Photo galleries of completed projects
  • Official non-government certificates attesting to its workmanship
The more experience a company has, the better its service and workmanship.

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 certification has its own exam and experience requirements. If a contractor is caught working without a license, they'll have to pay substantial fines.

Types of Windows Offered

There are many replacement window types you can choose from, and it's crucial to find a company that focuses on installing the ones you want. Browse a company's website and reviews for any of these types:

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

Customer Feedback

Perhaps the best way to vet window companies for your job is to find out what previous customers have said about them. Trustworthy sources for customer reviews include Yelp, Trustpilot, and the BBB 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 Castro Valley

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

Castro Valley homeowners could save up to $530 annually by upgrading to efficient windows. They'll also reduce their property's carbon dioxide emissions by 120 pounds per year.

How can I fix a rotting or molding window frame?

A molding or rotting window frame is usually a moisture issue. You might not have to replace the entire window. Instead, a simple framing job could do. It's recommended to consult a specialist to ensure proper sealing and weatherproofing.

What repair services do window companies offer?
