On average, homeowners in Littleton spend around $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

Installing new energy-efficient windows can significantly enhance your home's insulation, value, noise reduction, comfort, and appearance. Some clear indicators it's time for new windows include the following:

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  • Inefficient and outdated window styles that take away from your house's curb appeal.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

How To Choose a Window Company

Choosing a window installer with the proper qualifications helps ensure a smooth installation. We review the most important qualities to consider when selecting a qualified company below.

Experience

Make sure you hire a seasoned local installer with a long record of successfully installing and replacing windows. Installers that have been operating locally for many years are more likely to understand the local climate and local homeowners' needs. Get references from recent clients to confirm a company provides quality installations.

Certifications

Choose companies that are certified by leading window brands, and that have Fenestration and Glazing Industry Alliance (formerly AAMA) certification. Being certified indicates that they've been properly trained in installation best practices. Make sure installers are staff, not subcontractors, and confirm the technicians doing your job are certified.

Reputation

Spend time reading through online reviews, verifying with the Better Business Bureau (BBB), and asking for local references. Review customer feedback to verify that the company regularly provides good workmanship and customer service. Avoid companies with complaints of poor work or unfinished jobs.

Process

The best window installers will supply a comprehensive project plan and schedule, clear expectations, and an overview of all material and installation options. Avoid companies that offer unclear quotes or timelines that lack necessary details. Look for continual contact throughout the process to avoid surprises later in the project.

Warranties

Seek out window installers that guarantee their work and provide warranties on materials and labor. This demonstrates confidence in their work. Choose companies with unlimited lifetime warranties that can transfer to new homeowners.

Materials

Make sure the window company offers durable, long-lasting window options and top energy-saving window brands within your budget. Look for good energy ratings, enhanced UV protection, and design flexibility. Check that the window materials also come with manufacturer warranties.

Frequently Asked Questions About Window in Littleton, CO

In Littleton, the best time to install windows is when temperatures are mild, generally in the spring or fall. These conditions enable installers to work with less worry about extreme temperatures.

The ideal type of replacement windows for your Littleton home depends on the year your home was built –the average house in Littleton was built around 1987. For older homes, you might want to consider energy-efficient windows such as double-glazed windows, which are made to keep your home cool in the summer and warm in the winter. Wood frames also have a classic look that's great for older homes. For more modern homes, you may want to think about vinyl windows, which are affordable, durable and have a modern look.

Windows made from vinyl, wood, or fiberglass can last the longest, with some lasting up to 45 years. Vinyl windows are particularly durable and low-maintenance, making them an excellent choice if you want windows that will last a long time. Extra glazing can help reduce your heating and cooling bills over time.

The process for installing new windows typically starts with measuring the existing windows and ordering new ones. Next, a professional installer will prep the work area, take out the old windows, and put in the new ones. Once this is done, the installer will trim out the space and finish by sealing the window.

Window replacement companies in Littleton typically offer several services, such as installation, repair, window maintenance, cleaning, tinting, and weatherproofing.

Getting a professional window installer helps guarantee the job is done correctly. Professional installers will measure your windows properly in order to get a perfect fit and use the right techniques and materials to ensure your windows are correctly sealed and secure. Additionally, professional installers are likely to have access to higher quality materials and more knowledge than the average person, so you can expect your windows to be installed correctly and last for years to come.
