How To Choose a Window Company in Redwood City

Each window installer has different offerings and approaches. To ease the company search, keep these factors in mind:

Window Cost by Type

Replacing your windows is a major purchase, so balancing cost with value is vital. Choosing cheap windows could actually increase your overall cost, since they come with a reduced lifespan and more intensive maintenance needs. The style, material, and size of your replacement windows play the largest role in determining your final cost. Simple double-hung windows deliver great value with their straightforward style and simple mechanisms, while new skylights cost more to prepare for and install. It's recommended to consult a trusted window installer to figure out your ideal options.

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

Window TypesAverage Cost
Glass Block$53-$679

Window Material Cost

Materials also help determine a window's cost. You might select a material based on the local climate, your desired look, and your energy efficiency goals. For example, wooden 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

Other Window Replacement Costs

Your contractor will factor the price for your windows and the value of their services into its total estimate. Make sure to factor in the cost of installation, guarantees, and any other additional costs that your project may require.

Experience and Training

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

  • How long it's been in business
  • Photo galleries of completed projects
  • Private certificates attesting to its workmanship
The more experience a company has, the better its service and workmanship.

Licensing and Credentials

A California window business must be licensed as a Glazing Contractor, General Building Contractor and Window Coverings 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 substantial fines.

Types of Windows Offered

The kind of window you desire should influence your company choice. Not every contractor will necessarily be familiar with the types you want. A company website will reveal more about the window types it works with, such as:

Also, check the kind of window framing materials a company works with. Each material has distinct price points, life spans, and energy performance capabilities. Common materials include vinyl, wood, aluminum, fiberglass and composite.

Customer Feedback

One of the most surefire ways to evaluate a company is to read what other customers have said about their experiences. Trustworthy sources for customer reviews include the BBB, Yelp, and Google 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 Redwood City

How could new windows help my energy efficiency?

Redwood City homeowners could potentially save $440 per year by switching to efficient windows. They'll also lower their property's carbon dioxide emissions by 120 pounds per year.

According to the national Department of Energy, up to a third 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, improving your comfort and furthering your dollar.

What time of year should I replace my windows?

Window replacement can be done year-round. However, the installation process may be different depending on the season. Costs are often less expensive in winter when demand is reduced. Keep in mind, however, that this could overexpose your home to the elements. Speak with a licensed window professional to determine the best climate conditions for your replacement project.

What's different between a new construction window and a replacement window?

Replacement windows, also known as retrofit windows, are specifically designed for homes that already have existing windows. They are installed in the existing window opening, without the need to remove or alter the surrounding materials or structure. New construction windows, on the other hand are designed for mounting in a newly built home or during a significant renovation project. These windows include a nailing fin, which is a thin piece of metal or vinyl that protrudes from the frame. It's used to attach the window directly to the framing of the house, ensuring a secure fit.
