How To Choose a Window Company in Monrovia

Dependability is essential when it comes to choosing a window provider. However, your chosen company should also suit your needs and respect your vision. Keep in mind the following factors during your company search:

Window Cost by Type

Replacing your windows is a significant investment, so balancing cost with performance is vital. Choosing economy windows could actually increase your overall cost, since they come with a reduced lifespan and more intensive maintenance needs. The style, size, and material of your new windows are the most significant factors in your final cost. Transom windows are inexpensive with their simple size and straightforward form factor, while a custom-cut arch window in a master suite will cost more. If you're undecided, a window specialist can help you determine which options are best for your home.

In this table, you can find cost data for the most common residential window types to determine how much you might pay.

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

Window prices also vary based on material. Each option provides unique advantages depending on the local climate and energy efficiency needs. Fiberglass and vinyl are readily-available materials, so they tend to cost less. Likewise, aluminum and composites look sleek and stay strong in Monrovia's strong storms, so they tend to cost more.

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

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 factor in the cost of labor, guarantees, and any other additional costs that your project may need.

Experience and Training

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

  • How long it's been serving the Monrovia area
  • Photo galleries of projects its crews completed
  • Official non-government credentials 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 exam and experience requirements. If a contractor is caught working without a license, they'll have to pay hefty penalties.

Types of Windows Offered

The style of window you desire should influence your company choice. Not every installer will necessarily be familiar with the types you want. A company website will provide more about the window types it works with, such as:

  • Awning
  • Bay
  • Bow
  • Casement
  • Crank-out
  • Custom
  • Double- or single-hung
  • Egress
  • Garden
  • Jalousie
  • Picture
  • Sliding
  • Skylight
  • Specialty
  • Storm
  • Transom
  • Vent
Equally important to your desired windows' shape is their framing. Ask your window company if it offers the frame material you want, such as wood, composite, vinyl, fiberglass, or aluminum.

Customer Feedback

One of the most surefire ways to screen a company is to check what other customers have written about their experiences. You can find customer reviews on websites like Google, Trustpilot, the BBB, and Yelp. 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 Monrovia

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

By working with 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 supplies and skills to do the job safely and accurately. You can also get fast, informed answers to your questions and customized help to make the most of your new windows

How frequently should I upgrade or replace my windows?

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

Can I replace just my windows' glass and not their frames?

If your window has broken glass, it is not always necessary to replace the frame. Often, only the glass needs to be repaired unless the frame has also experienced extensive damage. A professional can determine exactly what's necessary during an estimate visit.
