How To Choose a Window Company in Glendora

Reliability is key when it comes to choosing a window company. However, your chosen company should also suit your priorities and respect your vision. Keep in mind 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. Choosing budget windows could actually increase your overall cost, due to their shorter lifespan and more intensive maintenance needs. The age of your home, together with the styles, sizes, and materials of replacement windows you opt for, can influence pricing. Transom windows are inexpensive with their simple size and straightforward form factor, while new skylights cost more to prepare for and install. A window expert can help you with choosing the solutions that fit your preferences.

This table shows average prices for various window types to give you an idea of what to expect.

Window TypesAverage 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

Materials also help determine a window's cost. You might select a material based on your energy efficiency goals, the local climate, and your desired look. 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 in Glendora's strong storms, so you'll spend far less on maintenance.

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

Other Window Replacement Costs

Your total cost for window replacement will also include warranty fees (if applicable), permit-related costs (if required), and labor. Ensure that you discuss each of these elements with an estimator before committing to a window company.

Experience and Training

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

  • How long it's been in business
  • 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 General Building Contractor, Window Coverings Contractor and Glazing Contractor if it takes on jobs valued at over $500. Each license has its own test and work requirements. If a contractor is caught working without a license, they'll have to pay substantial fines.

Types of Windows Offered

The style of window you want should influence your company choice. Not every installer will necessarily be familiar with the window brand you want. A company website will show more about the varieties of windows it focuses on, such as:

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

Customer Feedback

One of the simplest ways to evaluate a company is to read what other customers have said about their experiences. Read customer reviews on sites such as Trustpilot, Yelp, and Google. You can also view customer reviews and company ratings on the Better Business Bureau (BBB) website. 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 Glendora

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

Replacing your windows is a significant investment that greatly impacts your home's comfort and energy performance. Hiring a reputable window contractor to manage your project ensures your windows will fit correctly, operate effectively, and be properly insulated. Companies also typically include a warranty that covers required maintenance and most needed fixes.

When's the best time to replace my windows?

Since Glendora has mild winters, anytime is a good time to install new windows. When you reach out to an installer, ask the representative about when demand is lowest. By scheduling your job during an off-peak season, you could potentially save some money on labor costs.

What's the typical timeline for a professional window replacement?

The length of a window replacement project can vary greatly. It usually takes up to a month for the contractor to receive your windows from the manufacturer. The installation process itself often takes 40–60 minutes per window. However, larger windows or more complex installations may require additional time.
