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$233-$1433
Awning$338-$941
Bay$778-$5777
Custom$346-$962
Casement$269-$1562
Double-hung$125-$813
Egress$231-$576
Glass Block$46-$584
Picture$202-$1497
Single-hung$91-$1540
Skylight$115-$1390
Sliding$265-$1348
Storm$54-$380
Transom$282-$590

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$54-$1540
Composite$556-$1249
Fiberglass$91-$778
Vinyl$187-$1733
Wood$278-$1562

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

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

Ensure that the company focuses on window replacement. The more specialized training its staff has, and the longer it has been active, the more likely it will provide high-quality craftsmanship.

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.

Frequently Asked Questions About Window Replacement in Brentwood

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

By working with an expert, you don't need to worry about making measurement mistakes or lacking the right tools. A window installation team is well-equipped with the right tools and skills to do the job safely and accurately. You can also get fast, informed answers to your questions and personalized assistance to make the most of your new windows

Do I need a building permit to replace my home's windows?

Replacing windows may involve pulling permits, based on your local building codes and regulations. Some cities mandate permits for window replacement projects in cases involving structural changes or alterations to the window openings. It is always advisable to check with your local building department or consult a professional before undertaking any window replacement work.

I broke my window's glass. Could I replace just the glass?

If you shattered your window's glass, you don't necessarily need to replace the whole thing. In many cases, you can simply change the shattered glass pane without having to change the entire window unit. However, it's best to consult a window repair expert to determine the most appropriate repair for your specific situation.
