On average, Westminster homeowners will 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 noise reduction, comfort, value, insulation, and appearance. Some clear indicators it's time for new windows include the following:

  • High energy bills and discomfort from poor insulation around windows.
  • Inefficient and outdated window styles that reduce your house's curb appeal.
  • Windows that are hard to open, close, and lock properly due to wear and age.
  • Drafts and cold air leaking in from old, loose-fitting windows.
  • Fogging between window panes, condensation issues, or rotting window frames letting in moisture.

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 choosing a qualified provider below.

Experience

Find well-established local installers with considerable experience. Providers that have been installing windows locally for many years are more likely to understand the local climate and how to best meet your needs. Request references from recent customers to confirm a company’s reputation.

Certifications

Choose companies that are certified by major 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 rather than subcontractors, and confirm that any technicians working on your home are certified.

Reputation

Read through online feedback from past clients, check the Better Business Bureau (BBB), and ask for local references. Review customer feedback to confirm that the provider consistently delivers quality work and good customer service. Avoid contractors that have complaints of shoddy work or unfinished jobs.

Process

The highest-quality window installation providers will supply a comprehensive project plan and schedule, clear expectations, and an overview of product and installation options. Avoid companies that offer vague quotes or timelines that lack necessary details. Look for continual contact throughout the process to avoid surprises once work gets underway.

Warranties

Search for window installers that provide installation guarantees on labor and materials. This displays confidence in their work. Target companies that offer unlimited lifetime warranties that can pass to new homeowners.

Materials

Ensure your provider uses durable, energy-efficient window brands that work with your budget. Look for good energy ratings, enhanced UV protection, and design flexibility. Confirm the window materials have their own manufacturer warranties as well.

Frequently Asked Questions About Window in Westminster, CO

In Westminster, the best time to install windows is when temperatures are mild, generally in the spring or fall. This enables professionals to work without having to worry about extreme temperatures.

The best type of replacement window for your Westminster home will vary based on your home's age, as well as your style preference 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 are more popular in newer homes. Fiberglass windows are also a popular choice, as they can be energy efficient and long-lasting.

Windows made from wood, fiberglass, or vinyl can last the longest, with some lasting for close to 45 years. Vinyl windows are especially durable and low-maintenance, making them a good choice if you want windows that can last a long time. Double or triple glazing can help reduce your cooling and heating bills over time.

It varies on your specific needs and budget, but generally it's recommended to replace all your windows at once if they're not energy efficient. Replacing all your windows at once ensures that you'll get the most out of your energy efficiency and can possibly save you money in the long run. This is important in Westminster, where the average energy bills are roughly $968 a year.

Yes, many window companies offer payment plans for their services. Different companies have their own financing options, so you should shop around to find the best option for you. Depending on your income level, which is a median of $90,651 a year in Westminster, you may be able to qualify for special payment plans.

Window companies in Westminster usually offer a range of services, including measuring and installing new windows, fixing existing windows, replacing window glass, and hanging window treatments. They may also offer additional services such as weatherproofing or cleaning.

Professional installers will measure in order to get a perfect fit and will use the right materials and techniques to ensure your windows are properly sealed and fitted. Additionally, professional installers are likely to have access to higher quality materials and more experience than the average person, so you can count on your windows to be put in correctly and last for years to come.
