How Much Does Window Installation Cost In Washington?

Window installation and replacement costs will be influenced by several 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 Washington should expect to 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

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

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  • Outdated and inefficient window styles that reduce your house's curb appeal.

How To Choose a Window Company

Hiring an experienced window installer helps ensure good results and a great experience. Below, we outline the main criteria for selecting a qualified window installer.

Experience

Make sure you select 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 learn more about a provider’s service.

Certifications

Select an installer that is certified by major window brands and groups like the Fenestration and Glazing Industry Alliance, formerly known as the AMMA. Proper certification indicates that a contractor has training in window installation best practices. Confirm that installers are staff rather than subcontracted workers, and verify that any technicians working on your project are certified.

Reputation

Read through online reviews, check the Better Business Bureau (BBB), and ask for local references. Review customer feedback to make sure that the contractor consistently provides quality work and good customer service. Avoid companies that have complaints of shoddy work or unfinished jobs.

Process

The highest-quality window installation providers will supply a detailed project plan and schedule, clear expectations, and an overview of all product and installation options. Avoid companies that offer ill-defined quotes or timelines that don't provide specifics upfront. Look for continual contact throughout the process to avoid surprises later in the project.

Warranties

Research contractors that back their work with guarantees and provide warranties on labor and materials. This shows trust in their window installations. Seek out unlimited lifetime warranties that can even transfer to new homeowners.

Materials

Make sure the window company offers windows that are built to last and top energy-saving window brands within your budget. Look for enhanced UV protection, good energy ratings, and design flexibility. Check that the window materials also include manufacturer warranties.

Frequently Asked Questions About Window in Washington, DC

The ideal time to install windows in Washington is when temperatures are moderate, generally in the spring or fall. This allows installers to work without having to worry about the weather.

The best type of replacement window for your Washington 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 older — so your new windows match. Wood windows can provide a classic look and feel, while vinyl-framed windows are more popular in more modern homes. Fiberglass windows are also a popular choice, since they are energy efficient and durable.

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

The typical window installation process takes anywhere from a day and a half to two days, depending on the size and number of window openings being replaced. This includes removing the old windows, measuring for the new windows, installing the new windows, and sealing them in place. On average, it takes around 30 minutes to install each window.

In some cases, you can replace your own windows, but it's generally recommended to hire a professional. It's important to consider the local temperature when replacing windows, as it will impact the process. For example, the temperatures in Washington can reach an average high of 63, so you should consider energy-efficient windows that can deflect from the heat. It's also important to get the measurements right and follow the instructions for installation. Hiring a professional for your window replacement project will ensure that everything is done correctly.

Yes, many window installers offer financing 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 $93,547 a year in Washington, you may be able to qualify for special financing.

Window companies in Washington typically offer a wide range of services, including measuring and installing new windows, repairing existing windows, replacing window glass, and hanging window treatments. They may also offer extra services such as weatherproofing or cleaning.
