How To Choose a Window Company in Castle Rock

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

Window Cost by Type

Replacing your windows is a major purchase, so balancing cost with long life is vital. Choosing budget windows could actually raise your overall cost, due to their shorter lifespan and more intensive maintenance needs. The age of your home, as well as the styles, sizes, and materials of replacement windows you choose, can affect pricing. Single-hung windows often cost less due to their straightforward style and simple mechanisms, while a custom-cut arch window in a master suite will cost more. If you're undecided, a window provider can help you determine which options are best for your home.

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

Window TypesAverage Cost
Arched$236-$1450
Awning$342-$952
Bay$788-$5846
Custom$350-$974
Casement$272-$1580
Double-hung$127-$822
Egress$233-$583
Glass Block$46-$591
Picture$205-$1515
Single-hung$92-$1559
Skylight$116-$1407
Sliding$268-$1364
Storm$55-$385
Transom$285-$597

Window Material Cost

You'll also need to choose a window material. Homeowners frequently base their decision on energy efficiency objectives, the local climate and aesthetic preferences. 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$55-$1559
Composite$562-$1264
Fiberglass$92-$788
Vinyl$189-$1753
Wood$281-$1580

Other Window Replacement Costs

Your total cost for new windows will also include applicable warranty fees, permit application fees, and labor. Ensure that you discuss each of these elements with an estimator before committing to a window company.

Experience and Training

Peruse 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 portfolios that showcase past projects.

Ensure that the company specializes in window replacement. The more specific training its staff has, and the longer it has been in operation, the more likely it will deliver top-notch craftsmanship.

Licensing and Credentials

Colorado's contractor licensing requirements are distinct compared to many states. There is no central board that licenses window companies, but they might still need licenses from the cities and counties in which they operate. Colorado Springs and Denver license window installers, treating them as either general contractors or building contractors. For other areas, consult your local government.

Types of Windows Offered

No two window companies offer the same window types and materials. Find one that's an expert in the type you want for your home.

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

Customer Feedback

Reading other customers' stories is a great way to screen potential window companies. Read customer reviews on sites such as Yelp, Trustpilot, and Google. You can also view customer reviews and company ratings on the Better Business Bureau (BBB) website. 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 Castle Rock

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

Castle Rock homeowners could potentially save $440 per year by switching to efficient windows. They'll also decrease their property's carbon dioxide emissions by 460 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.

What time of year should I replace my windows?

Window replacement can occur 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. Talk to a licensed window professional to determine the best climate conditions for your replacement project.

How important are guarantees and extended support packages?

We strongly recommend choosing a window company that backs their work with a warranty for your protection. These policies usually cover manufacturer defects, workmanship errors, and material flaws that appear after installation. Verify the warranty terms with a window company before signing a contract.
