How To Choose a Window Company in Littleton

It's crucial to find a window replacement company that aligns with your individual values, needs, and preferences. Consider the following areas during your search:

Window Cost by Type

Replacing your windows is a substantial expense, so balancing cost with value is crucial. Choosing economy windows could actually raise your overall cost, since they come with a shorter lifespan and more intensive maintenance needs. The size, material, and style of your replacement windows play the largest role in determining your final cost. Transom windows are inexpensive with their simple size and straightforward form factor, while a sweeping, custom-size picture window will cost more. It's wise to consult a vetted window installer to determine your ideal options.

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

Replacement window prices also vary based on material. Each option provides different benefits depending on your climate and energy efficiency needs. 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$55-$1559
Composite$562-$1264
Fiberglass$92-$788
Vinyl$189-$1753
Wood$281-$1580

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 photo galleries that highlight past projects.

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

Licensing and Credentials

Colorado's contractor licensing requirements are unique among states. There is no statewide authority that licenses window companies, but they might still need licenses from local municipalities in which they operate. Denver and Colorado Springs license window installers, treating them as either general contractors or building contractors. For other areas, contact your local authorities.

Types of Windows Offered

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

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

Customer Feedback

Perhaps the best way to prescreen window companies for your job is to see what previous customers have said about them. You can find customer reviews on websites like Yelp, Trustpilot, Google, 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 Littleton

How could new windows help my energy efficiency?

Littleton homeowners could save up to $440 per year by installing efficient windows. They'll also reduce 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. Efficient windows help keep heat out in the summertime and in during the wintertime, improving your comfort and furthering your dollar.

What is the maintenance schedule for an average window, and how long will it last?

Windows don't last forever, and most vinyl models are designed to serve your home for 15 to 20 years. Over time, caulking and weatherstripping weaken, framing shifts, and window coatings fade. These changes result in energy loss, condensation, air leaks, and other expensive problems necessitating repair or replacement.

How long does a window replacement job take?

The length of a window replacement project can vary greatly. It usually takes up to a month for the contractor to receive your windows from the manufacturer. The installation process itself often takes 40–60 minutes per window. However, larger windows or more complex installations may require additional time.
