How To Choose a Window Company in Altadena

It's essential to find a window company that aligns with your specific values, needs, and preferences. Consider the following traits during your 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 window with top-notch quality and durability. Choosing economy windows could actually increase your overall cost, due to their shorter lifespan and more intensive maintenance needs. The overall cost of your window replacement will depend on the specific materials, styles, and sizes you need. Single-hung windows often cost less due to their straightforward style and simple mechanisms, while a custom-cut arch window in a master suite will cost more. It's advisable to consult a trusted installer to decide on your best options.

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

Window Types Average Cost
Arched $243-$1495
Awning $352-$981
Bay $812-$6025
Custom $361-$1004
Casement $281-$1629
Double-hung $131-$848
Egress $241-$601
Glass Block $48-$609
Picture $211-$1562
Single-hung $95-$1606
Skylight $120-$1450
Sliding $276-$1405
Storm $57-$397
Transom $294-$615

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 wear and warping. Vinyl is readily available and tends to cost less, but don't underestimate its strong durability and low maintenance needs.

Window Types Average Cost
Aluminum $57-$1606
Composite $580-$1303
Fiberglass $95-$812
Vinyl $195-$1807
Wood $290-$1629

Other Window Replacement Costs

Ask each installer you're considering 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 provider has served your area, the better its workmanship will likely be. Call a company representative to learn more about its experience, public and private credentials, and guarantees. Company websites often have photo galleries demonstrating previous work technicians have done.

Licensing and Credentials

A California window provider must be licensed as a Glazing Contractor, General Building Contractor and Window Coverings Contractor if it performs jobs valued at over $500. Each license has its own test 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 companies offer the same window designs and materials. Look for one that specializes in 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
Also, check the style of window framing materials a company works with. Each material has distinct price points, life spans, and energy performance capabilities. Common materials include aluminum, composite, wood, fiberglass and vinyl.

Customer Feedback

Perhaps the best way to evaluate window companies for your job is to see what previous customers have said about them. Trustworthy sources for customer reviews include Trustpilot, Yelp, and the BBB Ask 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 Altadena

Why should I hire a professional to install or replace my windows?

By hiring an expert, you don't need to worry about making measurement mistakes or lacking the right tools. A window installation crew is well-equipped with the right tools and training to do the job safely and precisely. You can also get fast, informed answers to your questions and personalized assistance to maximize your new windows' potential.

What is the maintenance schedule for an average window, and how long will it last?

Refer to your warranty information to approximate how long your windows are meant to last. Most home windows are built to serve 15–20 years. Check your windows for damage, leaks, and subpar performance to determine whether you need a replacement.

Will my window company install blinds?

Whether a company installs blinds ultimately depends on your state's licensing requirements and the company's own preferences. Many jurisdictions require window covering installers to get a separate license, and not every installer will carry one. If you'd like blinds with your new windows, ask a company representative if its crews can handle the cutting and installation. If a company can't work with blinds, they could recommend another company or subcontract the work.
