How To Choose a Window Company in Mountain View

Reliability is key when it comes to choosing a window company. 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

When it comes to window replacement, cost-effectiveness is king. Each window you purchase should deliver top-notch durability at an affordable price point. Although top-of-the-line windows may cost more upfront, they often provide better long-term value due to their longer lifespan. The final cost of your window replacement will depend on the particular materials, sizes, and styles you need. Transom windows are inexpensive with their simple size and straightforward form factor, while new skylights cost more to prepare for and install. It's recommended to speak with a trusted installer to figure out your most suitable options.

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

Window TypesAverage Cost
Glass Block$53-$680

Window Material Cost

You'll also need to pick a window material. Homeowners often make their selection by considering aesthetic preferences, the local climate and energy efficiency objectives. Aluminum windows are perfect for sleek, modern designs, but they cost more up-front. You'll pay less for wood windows up-front, but you'll need to invest in regular maintenance to prevent the frame from warping and wear. Vinyl is readily available and tends to cost less, but don't underestimate its strong durability and low maintenance needs.

Window TypesAverage Cost

Other Window Replacement Costs

Ask each company you're evaluating about warranty fees, labor costs, and permit fees. This will help you understand the overall expenses involved in the project.

Experience and Training

Examine a company's website and chat with a representative to learn more about its product and service offerings, pricing, and guarantees. Many companies also keep online galleries that highlight past projects.

Ensure that the company focuses on window replacement. The more specific training its staff has, and the longer it has been in operation, the more likely it will deliver high-quality workmanship.

Licensing and Credentials

A California window provider must be licensed as a General Building Contractor, Glazing Contractor and Window Coverings Contractor if it handles jobs valued at over $500. Each certification 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

No two businesses offer the same window styles and materials. Find one that focuses on the type you want for your home.

  • 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 varying price points, life spans, and energy performance capabilities. Common materials include wood, aluminum, composite, vinyl and fiberglass.

Customer Feedback

One of the most surefire ways to evaluate a company is to check what other customers have said about their experiences. Trustworthy sources for customer reviews include Yelp, Trustpilot, and Google Ask people you know who have used the company you'd like to hire, and ask a representative for professional references.

Frequently Asked Questions About Window Replacement in Mountain View

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 tools and knowledge to do the job safely and accurately. You can also get fast, informed answers to your questions and customized guidance to make the most of your new windows

How frequently should I upgrade or replace my windows?

Windows don't have an indefinite lifespan, and most wood models are designed to serve your home for 15–20 years. Over time, sealants weaken, framing shifts, and window coatings lose their efficacy. These changes result in air leaks, energy loss, condensation, and other expensive problems necessitating repair or replacement.

My window screen tore. How should I fix it?

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