How To Choose a Window Company in Thousand Oaks

With Thousand Oaks' sheer size, you're sure to find a trustworthy window replacement company that suits your values and preferences. As you gather estimates, keep the following factors in mind:

Window Cost by Type

When you're shopping for new windows, it's important to remember that there's more to cost than just purchase price. You want a high-quality and durable window. Choosing economy windows could actually increase your overall cost, due to their shorter lifespan and more intensive maintenance needs. The age of your home, together with the materials, sizes, and styles of replacement windows you select, can affect pricing. 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 choosing the solutions that fit your requirements.

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

Window TypesAverage Cost
Arched$226-$1391
Awning$328-$913
Bay$755-$5607
Custom$336-$934
Casement$261-$1516
Double-hung$122-$789
Egress$224-$559
Glass Block$44-$567
Picture$196-$1453
Single-hung$88-$1495
Skylight$112-$1349
Sliding$257-$1308
Storm$53-$369
Transom$274-$573

Window Material Cost

Window prices also vary based on material. Each option provides different benefits depending on the local climate and energy-saving goals. Fiberglass and vinyl are readily-available materials, so they tend to cost less. Likewise, composites and aluminum look sleek and stay strong against the elements, so they tend to cost more.

Window TypesAverage Cost
Aluminum$53-$1495
Composite$539-$1212
Fiberglass$88-$755
Vinyl$181-$1682
Wood$269-$1516

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 take into account the cost of labor, warranties, and any other extra expenses that your project may need.

Experience and Training

Examine a company's website and contact a representative to learn more about its product and service offerings, pricing, and warranties. Many window companies also keep online portfolios that showcase past projects.

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

Licensing and Credentials

A California window company must be licensed as a General Building Contractor, Window Coverings Contractor and Glazing Contractor if it performs jobs valued at over $500. Each license has its own test and work requirements. If a contractor is caught working without a license, they'll have to pay hefty penalties.

Types of Windows Offered

There are several replacement window types you can choose from, and it's crucial to find a company that is experienced with the ones you want. Check a company's website and reviews for any of these types:

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 composite, wood, fiberglass, aluminum and vinyl.

Customer Feedback

Perhaps the best way to screen window companies for your job is to find out what previous customers have said about them. You can find customer reviews on websites like Yelp, Trustpilot, Google, and the BBB. Speak with people you know who have used a company you're interested in, and ask a representative for a copy of its reference list.

Frequently Asked Questions About Window Replacement in Thousand Oaks

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 not having the right tools. A window installation team is well-equipped with the right supplies and training to do the job safely and accurately. You can also get fast, informed answers to your questions and tailored help to make the most of your new windows

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

Window replacement may involve securing permits, depending 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 generally a good idea to check with your local building department or consult a professional before starting any window replacement work.

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

If your window has a cracked pane, you do not always need to replace the frame. In many cases, only the glass needs to be replaced unless the frame has also experienced damage. A professional can determine exactly what's necessary during an estimate visit.
