How Installing Energy-Efficient Windows in Lafayette Saves You Money

Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to think about making the switch:

  • Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Replacing your windows with energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
  • Reduce your carbon footprint: By using less energy once upgrading to Energy Star certified windows, you’ll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.

Estimated Cost of Window Replacement in Lafayette

Windows come in various styles, purposes and shapes, so costs and services will vary considerably based on your project. Below, we describe the typical cost and services that you’ll find from window replacement companies.

How Much Do New Windows Cost?

Even though the average cost to replace a single window is around $600, it can range from $200 to $1,200. But costs differ considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door replacements, which will make your project cost more.

It’s important to keep in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Lafayette homeowners $579+ a year when replacing single-pane windows.

Asking for free quotes from multiple installers is the best way to figure out which one will work best for your budget.

What Services do Window Installers Offer?

Generally, there are two types of window replacement services companies provide: full-frame and pocket installations.

A full-frame installation replaces the complete window, including the windowsill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you will most likely need a full-frame installation instead.

If you’re not sure which window installation service you should get, your installer should be able to assist you. Typically, the choice depends on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Lafayette

In our hunt to find the most reliable, eco-friendly window installers in Lafayette, the EcoWatch team examined dozens of companies before deciding on these. Along with energy efficiency, we reviewed several window installers in Lafayette and assigned rankings using the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve Lafayette so you can find the right window installation company near you.

Work Quality

We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer included in our guide to ensure its contractors are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including professionalism, cost, warranty, quality of installation, quality of parts and more.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a proven track record in the industry. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Lafayette, CA Window Replacement FAQs

How much should window installation cost?

The national average cost to replace a single window is around $600 but can range between $200 and $1,200, based on several factors. The price is typically influenced by the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

What are the different kinds of windows?

There are several different types of windows you can get for your house, such as double-hung and single-hung windows, bay windows, awning windows, casement windows, slider windows, picture windows and transom windows.

What services do window replacement companies offer?

Window installation professionals go to your property to remove your old windows and replace them with new ones. Some providers install products sold by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.

Should I replace all my windows at once?

If your windows are more than 20 years old, it’s most likely time to replace all of them. At that point, they are typically less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
