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 are the most significant factors in your final cost. Single-hung windows often cost less due to their straightforward style and simple mechanisms, while a sweeping, custom-size picture window will cost more. An installer can guide you through picking the solutions that fit your needs.

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$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

Window prices also vary based on material. Each option gives you different benefits depending on the local climate and energy efficiency needs. Vinyl and fiberglass are readily-available materials, so they tend to cost less. Likewise, aluminum and composites 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

Your total cost for new windows will also include warranty fees (if applicable), permit application fees, and labor. Ensure that you discuss each of these aspects with a sales representative before committing to a window company.

Experience and Training

Choose a provider that focuses on window replacement and repair, and look for this information on its website:

  • How long it's been in business
  • Photo galleries of projects its crews completed
  • Privately-issued accreditations attesting to its workmanship
The more experience a company has, the better its service and workmanship.

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 the cities and counties in which they operate. Both Denver and Colorado Springs license window installers, treating them as either general contractors or building contractors. For other areas, check with your local government.

Types of Windows Offered

No two businesses offer the same window types and materials. Find one that focuses on the type you want for your home.

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

Customer Feedback

Perhaps the best way to screen window companies for your job is to see what previous customers have said about them. Read customer reviews on sites such as Trustpilot, Yelp, and Google. You can also view customer reviews and company ratings on the Better Business Bureau (BBB) website. 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 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 in during the wintertime, both protecting your comfort and saving you money.

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

Refer to your product warranty to determine how long your windows are meant to last. Most residential windows are built to serve 15–20 years. Check your windows for damage, water infiltration, and poor performance to determine whether your windows should be replaced.

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

It could take up to 4–7 weeks 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 highly skilled crew can finish the installation quicker.
