How To Choose a Window Company in Fort Collins

With Fort Collins' large population, you're sure to find a reputable replacement window company in line with your values and preferences. As you gather estimates, keep the following factors in mind:

Window Cost by Type

When you're shopping for replacement windows, it's essential to remember that there's more to cost than just purchase price. You want a high-quality and durable window. Choosing cheap windows could actually increase your overall cost, since they come with a shorter lifespan and more intensive maintenance needs. The overall cost of your replacement windows will hinge on the specific sizes, styles, and materials you need. Simple double-hung windows deliver great value with their straightforward style and simple mechanisms, while new skylights cost more to prepare for and install. It's wise to speak with a vetted window installer to decide on your ideal options.

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

Window TypesAverage Cost
Arched$221-$1357
Awning$320-$891
Bay$737-$5472
Custom$328-$912
Casement$255-$1479
Double-hung$119-$770
Egress$218-$546
Glass Block$43-$553
Picture$192-$1418
Single-hung$86-$1459
Skylight$109-$1317
Sliding$251-$1276
Storm$51-$360
Transom$267-$559

Window Material Cost

Replacement window prices also vary based on material. Each option offers unique advantages depending on your 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$51-$1459
Composite$526-$1183
Fiberglass$86-$737
Vinyl$177-$1641
Wood$263-$1479

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 assess the cost of installation, warranties, and any other supplemental fees that your project may need.

Experience and Training

The longer a window company has been operating, the better its workmanship will likely be. Speak with a company representative to learn more about its guarantees, public and private credentials, and experience. Company websites often have photo galleries showing off previous work technicians have done.

Licensing and Credentials

Colorado's contractor licensing requirements are distinct from other states. There is no single regulatory body 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, consult your local government.

Types of Windows Offered

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

Equally important to your desired windows' shape is their framing. Ask your window company if it offers the frame material you want, such as wood, composite, vinyl, fiberglass, or aluminum.

Customer Feedback

One of the easiest ways to screen a company is to read what other customers have said about their experiences. You can find customer reviews on websites like Trustpilot, Yelp, the BBB, and Google. Ask people you know who have used the company you're evaluating, and ask a representative for professional references.

Frequently Asked Questions About Window Replacement in Fort Collins

How could new windows help my energy efficiency?

In Fort Collins specifically, most homeowners using efficient windows reduce their carbon emissions by 460 pounds yearly. This means they save $520 on their annual electricity costs.

The U.S. Department of Energy states that 25%–30% of a home's heating and cooling capacity is used to compensate for heat gain and heat loss through windows. By upgrading to new, more efficient windows, you can enhance your home's energy efficiency and minimize your electricity bills.

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

Windows don't last forever, and most wood models are designed to serve your home for 15–20 years. Over time, weatherproofing materials weaken, framing contracts and expands, and window coatings lose their efficacy. These changes result in condensation, energy loss, air leaks, and other expensive problems necessitating repair or replacement.

Is it better to replace all my windows at once, or just a few at a time?

To form a window replacement approach, consider your financial situation, home improvement goals, and energy efficiency targets. A phased replacement enables budget management and concentrate on the windows that need the most attention, but you'll also notice lesser improvements in efficiency. A entire-home replacement will require a larger investment up front, but you'll see a more noticeable energy efficiency improvement.
