How To Choose a Window Company in Sunnyvale

With Sunnyvale's robust local economy, you're sure to find a reputable window company that suits your values and preferences. As you contact companies, keep the following factors in mind:

Window Cost by Type

When it comes to window replacement, value is most important. Each window you buy should offer maximum durability at an affordable price point. Choosing economy windows could actually raise your overall cost, since they come with a reduced lifespan and more intensive maintenance needs. The material, style, and size of your new windows have the greatest impact on 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. It's recommended to consult a trusted installer to figure out your most suitable options.

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

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

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

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 installer you're evaluating about labor costs, warranty fees, and permit fees. This will help you get a better picture of the total costs involved in the project.

Experience and Training

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

  • How many years it's been operating
  • 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 provider must be licensed as a Window Coverings Contractor, Glazing Contractor and General Building Contractor if it performs jobs valued at over $500. Each certification has its own test and work requirements. If a contractor is caught working without a license, they'll have to pay steep fines.

Types of Windows Offered

There are many replacement window types you can choose from, and it's important to find a company that has expertise 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
Also, check the style of window framing materials a company works with. Each material has different price points, life spans, and energy performance capabilities. Common materials include fiberglass, vinyl, wood, composite and aluminum.

Customer Feedback

Perhaps the best way to prescreen window companies for your job is to read what previous customers have said about them. You can find customer reviews on websites like Google, the BBB, Trustpilot, and Yelp. Speak with people you know who have used a company you're interested in, and ask a representative for a copy of its reference list.

Frequently Asked Questions About Window Replacement in Sunnyvale

What are the benefits of hiring a window installer?

By working with a professional, you don't need to worry about making measurement mistakes or not having the right tools. A window installation team 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 assistance to make the most of your new windows

What time of year should I replace my windows?

Since Sunnyvale has very mild winters, any time is a good time to put in new windows. When you contact an installer, ask the representative about when demand is at its lowest. By scheduling your job during an off-peak period, you could potentially save some money on labor costs.

My window screen tore. How should I fix it?

It depends on the size of the tear and its location on your window. You can usually address small tears yourself using a special kit. Some window companies will supply you with one when they set up your windows, or you can get one for $5–10 from a home improvement store. Bigger tears, or those located at the edge of a window, usually need professional repair.
