How To Choose a Window Company in Fort Collins

With Fort Collins' robust local economy, you're sure to find a reliable window replacement company that suits your values and preferences. As you make calls, keep the following factors in mind:

Window Cost by Type

When it comes to upgrading your windows, value is paramount. Each window you replace should deliver maximum durability at a fair price point. Choosing cheap windows could actually increase your overall cost, due to their reduced lifespan and more intensive maintenance needs. The size, material, and style of your new windows play the largest role in determining your final cost. Transom windows are inexpensive with their simple size and straightforward form factor, while new skylights cost more to prepare for and install. It's wise to speak with a reliable window installer to figure out your best 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

Window prices also vary based on material. Each option gives you different benefits 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

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

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 public and private credentials, guarantees, and experience. Company websites often keep photo galleries showcasing previous work technicians have done.

Licensing and Credentials

Colorado's contractor licensing requirements are unique among states. There is no single regulatory body 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

The style of window you desire should influence your company choice. Not every contractor will necessarily be familiar with the window brand you want. A company website will provide more about the kinds of windows it deals with, such as:

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 vinyl, composite, aluminum, wood and fiberglass.

Customer Feedback

One of the most surefire ways to screen a company is to see what other customers have said about their experiences. 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. 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 Fort Collins

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

Fort Collins homeowners could potentially save $520 each year by upgrading 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. Efficient windows help keep heat out in the summertime and retain heat in the wintertime, improving your comfort and furthering your dollar.

How frequently should I upgrade or replace my windows?

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, leaks, and subpar performance to determine whether you need a replacement.

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

The answer to this question is primarily influenced by your finances, how your windows are doing overall, and your plan for your home. Replacing all your windows at once can improve your home's insulation and add value to your home, while replacing your windows over time can protect your budget and let you focus on the windows in the worst condition. Ultimately, you should weigh the pros and cons and select the approach that aligns with your goals.
