How To Choose a Window Company in Brentwood

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

Window Cost by Type

Replacing your windows is a significant undertaking, so balancing cost with value is crucial. Although top-of-the-line windows may cost more upfront, they often provide better long-term value due to their extended lifespan. The size, style, and material of your new windows have the greatest impact on your final cost. Simple double-hung windows deliver great value with their straightforward style and simple mechanisms, while a custom-cut arch window in a master suite will cost more. An installer can help you with picking the products that fit your preferences.

To help you form a rough estimate, this table shows the typical cost of the most common residential window types.

Window TypesAverage Cost
Arched$234-$1,434
Awning$338-$942
Bay$779-$5,779
Custom$347-$963
Casement$270-$1,562
Double-hung$126-$813
Egress$231-$577
Glass Block$46-$585
Picture$203-$1,498
Single-hung$92-$1,541
Skylight$116-$1,391
Sliding$265-$1,348
Storm$55-$381
Transom$283-$591

Window Material Cost

Materials also help determine a window's cost. You might choose a material based on your energy efficiency goals, your desired look, and the local climate. 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$55-$1,541
Composite$556-$1,250
Fiberglass$92-$779
Vinyl$187-$1,734
Wood$278-$1,562

Other Window Replacement Costs

Your total cost for new windows will also include applicable warranty fees, permit-related costs (if required), and labor. Make sure to discuss each of these factors with a sales representative before committing to a window company.

Experience and Training

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

  • The number of years it's been in business
  • Photo galleries of projects its crews completed
  • Official non-government accreditations attesting to its workmanship
The more experience a company has, the better its service and workmanship.

Licensing and Credentials

A California window company must be licensed as a Window Coverings Contractor, Glazing Contractor and General Building Contractor if it takes on 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 hefty penalties.

Types of Windows Offered

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

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

Customer Feedback

Reading other customers' stories is an excellent way to screen potential window companies. You can find customer reviews on websites like Google, Trustpilot, the BBB, 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.
