How Installing Energy-Efficient Windows in Nevada Saves You Money

By switching to energy-efficient windows, you and your family can enjoy several benefits, such as:

  • Reduce your carbon footprint: In Nevada, you can reduce your indirect greenhouse gas emissions by about 715 pounds per year once you install energy-efficient windows.
  • Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
  • Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.
  • Save money on power bills: Since energy-efficient windows reduce the amount of energy used to heat or cool your home, they can help you save about $403 annually on your energy bills in Nevada.

Estimated Cost of Window Replacement in Nevada

Each window replacement company offers various services and has different costs depending on a few factors.

How Much Do New Windows Cost?

On average, homeowners in Nevada can anticipate that most window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. These amounts are based on specific characteristics of your installation, such as size, material, number of windows, the location of your home, type and more.

Whether or not you opt for energy-efficient windows is another factor that will affect the cost. These will typically cost more than other windows, but on the other hand, you can save about $403 a year on your energy bills in Nevada.

Asking for free quotes from several companies is the best way to find out which one is right for you.

What Services do Window Installers Offer?

The first thing to ask yourself when considering a window replacement is: Do you want a full-frame installation or a pocket installation?

Full-frame installations involve replacing the full window, including the trim, frame and sill. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable rot. Full-frame installations are more involved and will raise the overall cost. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are on the simpler end and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.

Your window installer can help you choose which type of installation you should get.

How We Choose the Best Window Installers in Nevada

In our search to find the most reliable, eco-friendly window installers in Nevada, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we evaluated each installer and ranked them based on the following methodology:

Service Area

Because this is a guide for Nevada, we only included companies that serve the city. There are certainly reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Nevada.

Work Quality

When picking new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the type of window you choose. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have nice feedback about their service from a certain company, it won't be featured on EcoWatch.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers' prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Nevada's climate, homeowners will want to mitigate low efficiency, water damage and rot. We factored in local experience to reflect the ability of Nevada window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

Nevada, IA Window Replacement FAQs

What is the average cost to replace windows in a home?

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

Which kind of window should I get?

Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. If you want to be sure you'll get the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.

What do window installers do?

Window installation professionals cover the entire process — from replacing old windows with new ones to cleaning up after the installation. Additionally, some companies offer window manufacturing, customization and repairs.

When is it time to replace your windows?

Windows typically have a lifespan of 20 to 30 years, but anytime you see damage on your windows, it's a good time to have an expert take a look at them to determine if they need any repairs or replacements.

Should I replace my windows all at the same time?

If your windows are greater than 20 years old, it's probably time to replace all of them. By that point, they are typically less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.
