How To Choose a Window Company in Westmont

It's crucial to find a window replacement company that matches your unique values, needs, and preferences. Consider the following traits during your search:

Window Cost by Type

When it comes to replacing your windows, value is key. Each window you buy should offer optimal durability at a reasonable price point. Although high-quality replacement windows may be more expensive to buy, they often provide better long-term value due to their extended lifespan. The final cost of your replacement windows will hinge on the specific sizes, materials, and styles you need. Simple double-hung windows deliver great value with their straightforward style and simple mechanisms, while a sweeping, custom-size picture window will cost more. A professional can guide you through choosing the options that fit your preferences.

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
Arched$243-$1495
Awning$352-$981
Bay$812-$6025
Custom$361-$1004
Casement$281-$1629
Double-hung$131-$848
Egress$241-$601
Glass Block$48-$609
Picture$211-$1562
Single-hung$95-$1606
Skylight$120-$1450
Sliding$276-$1405
Storm$57-$397
Transom$294-$615

Window Material Cost

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

Window TypesAverage Cost
Aluminum$57-$1606
Composite$580-$1303
Fiberglass$95-$812
Vinyl$195-$1807
Wood$290-$1629

Other Window Replacement Costs

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

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 galleries that showcase past projects.

Ensure that the company focuses on window replacement. The more specialized training its staff has, and the longer it has been in business, the more likely it will provide excellent craftsmanship.

Licensing and Credentials

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

Types of Windows Offered

The kind of window you want should factor into your company choice. Not every installation crew will necessarily be familiar with the types you want. A company website will show more about the kinds of windows it specializes in, such as:

Also, check the kind of window framing materials a company works with. Each material has different price points, life spans, and energy performance capabilities. Common materials include vinyl, wood, aluminum, 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 Yelp, Google, Trustpilot, and the BBB. 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 Westmont

How much energy and money will I save by upgrading my windows?

Westmont homeowners could save up to $510 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 federal Department of Energy, as much as 33% of a house's HVAC usage is to compensate for the heat or cold entering through windows. Energy-efficient windows help keep heat out in the summertime and retain heat in the wintertime, both protecting your comfort and saving you money.

How can I fix a rotting or molding window frame?

Mold and rot often set in due to moisture issues or water damage. Fortunately, you might not need to replace your windows to solve this annoying and unsightly issue. A window company can eliminate the rot, restore the affected area, and reset the tight seal your windows need to function at their best.

What's the typical timeline for a professional window replacement?

It could take about a month to begin installation after the contractor orders your windows from the manufacturer. The installation itself usually takes around an hour per window. A larger window will take more time to get done, but a particularly experienced crew can get the job done faster.
