How To Choose a Window Company in Palo Alto

It's essential to find a window company that meets your individual values, needs, and preferences. Consider the following points during your search:

Window Cost by Type

When you're shopping for new windows, it's crucial to remember that there's more to cost than just purchase price. You want a window with top-notch quality and durability. Choosing budget windows could actually raise your overall cost, due to their reduced lifespan and more intensive maintenance needs. The final cost of your window replacement will rely on the particular styles, sizes, and materials you need. Simple double-hung windows deliver great value with their straightforward style and simple mechanisms, while new skylights cost more to prepare for and install. An installer can help you with choosing the solutions that fit your requirements.

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

Window TypesAverage Cost
Glass Block$53-$680

Window Material Cost

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

Window TypesAverage Cost

Other Window Replacement Costs

Ask each installer you're evaluating about labor costs, warranty fees, and permit fees. This will help you get a clear picture of the overall expenses involved in the project.

Experience and Training

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

Licensing and Credentials

A California window company must be licensed as a General Building Contractor, Glazing Contractor and Window Coverings Contractor if it performs jobs valued at over $500. Each license has its own exam and work 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 essential to find a company that is experienced with the ones you want. Check 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
Equally important to your desired windows' shape is their framing. Ask your window company if it offers the frame material you want, such as composite, vinyl, aluminum, wood, or fiberglass.

Customer Feedback

One of the easiest ways to vet a company is to check what other customers have said about their experiences. Trustworthy sources for customer reviews include Trustpilot, Yelp, and the BBB 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 Palo Alto

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

Palo Alto homeowners could potentially save $560 annually by upgrading to efficient windows. They'll also reduce their property's carbon dioxide emissions by 120 pounds per year.

According to the national Department of Energy, as much as 33% of a house's HVAC usage is to compensate for the heat or cold entering through windows. Efficient windows help keep heat out in the summertime and in during the wintertime, both protecting your comfort and saving you money.

What should I do if a window is molding or has rot?

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 window expert to ensure a proper seal.

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 around an hour per window. However, larger windows or more complex installations may require additional time.
