How Much Does Window Installation Cost In Fort Collins?

The price of window installation or replacement is influenced by a number of factors, including the number and size of the windows, the materials you choose, and how difficult your windows are to access or install. On average, Fort Collins homeowners will spend roughly $280 per window*. Below are additional cost breakdowns. *Cost data based on sample pricing for window installation from multiple retailers and adjusted for local cost of living.

When To Replace Windows

New, energy-efficient windows can substantially improve your home's noise reduction, appearance, value, insulation, and comfort. Obvious signs that it's time for window replacement include the following:

  • Inefficient and outdated window styles that reduce your house's curb appeal.
  • Condensation issues, fogging between window panes, or rotting window frames that allow moisture intrusion into the home.
  • A chilly house and high energy bills due to poor insulation.
  • Drafts and cold air leaking in through old, loose-fitting windows.
  • Windows that are difficult to open, close, or lock properly due to wear and age.

How To Choose a Window Company

Choosing a window installer with the right qualifications helps ensure a smooth installation. We review the most important considerations for selecting a qualified company below.

Experience

Look for highly-regarded local companies with many years, ideally decades, of experience successfully installing all kinds of windows. These providers are more likely to understand Fort Collins' climate and your requirements. Ask for references from recent clients to verify quality and experience.

Certifications

Choose an installer that’s accredited like major window manufacturers, and that has Fenestration and Glazing Industry Alliance (formerly AAMA) certification. Appropriate accreditation means they've received appropriate instruction in installation best practices. Verify that installers are staff, not subcontracted laborers, and confirm that the technicians assigned to your job have certification.

Reputation

Spend time reviewing online feedback, checking the Better Business Bureau (BBB), and asking for local references. Review customer feedback to confirm that the company delivers consistent quality workmanship and great service. Avoid companies with complaints of shoddy or unfinished work.

Process

The most qualified company will take time to provide you with a detailed project plan, timeline, expectations, and reviews of all material and installation options. Beware of vague quotes or timelines that don't provide enough specifics upfront. Look for continual communication throughout the process to avoid surprises once the project gets underway.

Warranties

Seek out window installers that back their installations with warranties on materials and labor. This demonstrates confidence in their work. Research companies that offer unlimited lifetime warranties that can transfer to new homeowners.

Materials

Verify that your window installer works with trusted, long-lasting brands, offers energy-saving window options, and fits your budget. Look for window options with enhanced UV protection, good energy ratings, and design flexibility. Check whether the materials come with their own manufacturer warranties.

Frequently Asked Questions About Window in Fort Collins, CO

In Fort Collins, the best time to install windows is when temperatures are mild, generally between the spring and fall. This enables professionals to work without having to worry about extreme temperatures.

The best type of replacement window for your Fort Collins home will vary based on your home's age, as well as your personal style and budget. You'll want to consider the style of your home — such as if it's more modern — so your new windows match. Wooden windows can provide a traditional look and appearance, while vinyl windows tend to be popular in more modern homes. Fiberglass-framed windows are also a popular choice, as they are energy efficient and durable.

The types of window that typically last longest are ones made of vinyl or wood, with triple glaze for extra insulation. Vinyl windows are famous for their durability and require little maintenance, while wood windows offer a more timeless look. Tripling up on the glazing will help reduce energy costs over time. This is especially helpful during Fort Collins' cold winters.

The window installation process typically involves measuring and ordering the windows, prepping the area for installation, taking out the existing window, installing the new one, and insulating the frame. Depending on the type of window being put in, additional steps may be required.

Replacing your own windows can be a difficult task, especially in Fort Collins, where temperatures can get quite cold. It's generally best to get a skilled window installer. A professional installer has the knowledge and experience that ensures your windows are correctly installed and that you get the most out of your investment.

Yes, many window companies offer payment plans for their services. Different companies have different financing options, so you should do your research to find the best option for you. Depending on your income level, which is a median of $78,977 a year in Fort Collins, you may be able to qualify for lower interest rates.
