How To Choose a Window Company in Sunnyvale

With Sunnyvale's sheer size, you're sure to find a reliable replacement 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 upgrading your windows, cost-effectiveness is most important. Each window you buy should deliver top-notch durability at a fair price point. Although premium replacement windows may be more expensive to buy, they often yield better long-term value due to their extended lifespan. The total cost of your replacement windows will rely on the specific sizes, styles, and materials you need. Simple double-hung windows deliver great value with their straightforward style and simple mechanisms, while a sweeping, custom-size picture window will cost more. If you're unsure, a window provider can help you figure out which options are ideal for your home.

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

Window TypesAverage 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 TypesAverage Cost
Aluminum$63-$1792
Composite$647-$1453
Fiberglass$106-$906
Vinyl$218-$2016
Wood$323-$1817

Other Window Replacement Costs

Ask each window 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 handles jobs valued at over $500. Each certification 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

No two window installers offer the same window designs and materials. Look for one that's an expert in the type you want for your home.

Equally important to your desired windows' shape is their framing. Ask your window provider if it offers the frame material you want, such as wood, composite, vinyl, aluminum, or fiberglass.

Customer Feedback

Perhaps the best way to vet window companies for your job is to read what previous customers have said about them. Trustworthy sources for customer reviews include Trustpilot, Google, and Yelp 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 Sunnyvale

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

By working with an expert, you don't need to worry about measurement missteps or not having the right tools. A window installation crew is well-equipped with the right tools and skills to do the job safely and precisely. You can also get fast, informed answers to your questions and tailored assistance to maximize your new windows' potential.

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 reach out to an installer, ask the representative about when demand is lowest. By scheduling your job during an off-peak time, you could potentially save some money on labor costs.

How can I fix a broken window screen?

It depends on the tear size and where it's located on your window. You can usually fix small tears yourself using a special kit. Some window companies will supply you with one when they install your windows, or you can purchase one for $5–10 from a local hardware store. Larger tears, or those located at the edge of a window, usually need expert help.
