How To Choose a Window Company in Milpitas

An exceptional reputation is crucial when it comes to choosing a window installer. However, your chosen company should also suit your priorities and appreciate your vision. Keep in mind the following factors during your company search:

Window Cost by Type

Replacing your windows is a major purchase, so balancing cost with long life is vital. Although high-quality windows may come with a higher initial price tag, they often provide better long-term value due to their longer lifespan. The material, style, and size of your new windows play the largest role in determining your final cost. 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. If you're unsure, a window provider can help you decide which options are most suitable 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 $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

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

Window Types Average 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 considering about labor costs, warranty fees, and permit fees. This will help you understand the total costs involved in the project.

Experience and Training

The longer a window provider has been operating, the better its workmanship will likely be. Contact a company representative to learn more about its experience, guarantees, and public and private credentials. Company websites often have photo galleries where you can see previous work technicians have done.

Licensing and Credentials

A California window installer must be licensed as a General Building Contractor, Glazing Contractor and Window Coverings Contractor if it handles 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 substantial fines.

Types of Windows Offered

There are a variety of replacement window types you can choose from, and it's important to find a company that is experienced with the ones you want. Search a company's website and reviews for any of these types:

  • 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, fiberglass, composite, vinyl and wood.

Customer Feedback

One of the best ways to vet a company is to read what other customers have said about their experiences. You can find customer reviews on websites like Google, Trustpilot, Yelp, and the BBB. 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 Milpitas

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

In Milpitas specifically, most homeowners using efficient windows cut their carbon emissions by 120 pounds yearly. This means they save $560 on their annual electricity costs.

The U.S. Department of Energy states that 25%–30% of a home's heating and cooling capacity is used to compensate for heat gain and heat loss through windows. By purchasing new, more efficient windows, you can enhance your home's energy efficiency and minimize your electricity bills.

Do I need a building permit to replace my home's windows?

Replacing windows may involve pulling permits, based on your local building codes and regulations. Some areas mandate permits for window replacement projects when they involve structural changes or alterations to the window openings. We recommend you check with your local building department or consult a professional before starting any window replacement work.

Should I replace my windows a couple at a time, or is it more economical to replace them all at once?

To form a window replacement approach, consider your finances, home improvement goals, and energy efficiency targets. A phased replacement allows for cost savings and focus on the windows that need the most attention, but you'll also notice smaller gains in efficiency. A whole-home replacement will require a larger investment up front, but you'll see a more dramatic energy efficiency improvement.
