How Much Does Window Installation Cost In Boulder?

Window installation and replacement costs vary based on a number of factors, including how difficult your windows are to access or install, the materials you choose, and the number and size of the windows. On average, homeowners in Boulder will spend around $270 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

Installing new energy-efficient windows can substantially boost your home's comfort, value, appearance, noise reduction, and insulation. Some clear indicators it's time to invest in new windows include the following:

  • Windows that are hard to open, close, and lock properly due to age and wear.
  • High energy bills and a chilly house due to poor insulation around windows.
  • Outdated and inefficient window styles that detract from your house's curb appeal.
  • Cold air and drafts coming in through old, loose-fitting windows.
  • Condensation issues, fogging between window panes, or rotting window frames that let in moisture.

How To Choose a Window Company

For a successful window replacement, you want to hire an installation contractor with proven expertise. Below, we go over the most important qualifications for picking a window installer.

Experience

Make sure you select a seasoned local installer with a proven track record of successfully installing and replacing windows. Providers that have been operating locally for many years are more likely to have a deep knowledge of the local climate and local homeowners' needs. Get references from recent clients to learn more about a provider’s service.

Certifications

Look for installers that are backed by leading window manufacturers and certified by leading industry groups, including the Fenestration and Glazing Industry Alliance, formerly known as the AAMA. Appropriate credentials mean that a provider has received suitable training in quality installation methods. Ensure installers are employees rather than subcontractors. Verify that any technicians working on your home hold the right certifications.

Reputation

Spend time going through online reviews, checking the Better Business Bureau, and asking for references from people in your area. Review customer feedback to verify that a company consistently does quality work and provides good service. Avoid companies with complaints of poor work or unfinished jobs.

Process

The most experienced window installers will supply a comprehensive project plan and schedule, clear expectations, and an overview of material and installation options. Avoid companies that offer vague quotes or timelines that don't provide specifics upfront. Look for regular contact throughout to avoid surprises later in the project.

Warranties

Look for companies that stand behind their work and provide warranties on labor and materials. This demonstrates trust in their window installations. Look for unlimited lifetime warranties that can even transfer to new homeowners.

Materials

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

Frequently Asked Questions About Window in Boulder, CO

In Boulder, the best time to install windows is when temperatures are mild, generally in the spring or fall. These conditions allow installers to do their work without having to worry about extreme temperatures.

The best type of replacement window for your Boulder home will depend 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 newer — so your new windows match. Wooden windows can give a traditional look and feel, while vinyl windows are more popular in newer homes. Fiberglass windows are also a popular choice, since they are energy efficient and durable.

Windows made from vinyl, fiberglass, or wood are known to last the longest, with some lasting up to 45 years. Vinyl windows are particularly durable and low-maintenance, making them a great choice if you want windows that can last a long time. Adding more glazing can help reduce your heating and cooling bills over time. This is especially helpful during Boulder's cold winters.

The process for window installation typically includes taking measurements, removing the old windows, installing the new windows, inspecting for proper insulation, and caulking around the edges of the frames. Additional steps may be necessary depending on the type of window being installed.

Replacing your own windows can be a difficult task, especially in Boulder, where temperatures can get quite warm. It's generally best to get a professional window installer. Their knowledge and experience ensures your windows are securely installed and that you get the most out of your investment.

Yes, many window installers offer payment plans for their services. Different companies have different financing options, so you should shop around to find the best option for you. Depending on your income level, which is a median of $74,902 a year in Boulder, you may be able to qualify for special financing.
