How Installing Energy-Efficient Windows in Meridian Saves You Money

When you upgrade to energy-efficient windows, you may see several benefits, such as:

  • Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Replacing your windows with energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.
  • Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.

Estimated Cost of Window Replacement in Meridian

Windows come in various styles, shapes and purposes, so costs and services will vary remarkably based on your project. Below, we go over the typical cost and services that you can get from window replacement companies.

How Much Do New Windows Cost?

Generally, Meridian homeowners can anticipate their replacement window installations to range from $250 to $1,200. The average cost is at about $600. How much it will cost you varies based on several factors, such as size, type, the location of your home, material, number of windows and more.

With windows, efficiency is the most important factor for most homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Meridian homeowners $443+ per year after replacing single-pane windows.

Costs will also vary depending on the material of your frame. Aluminum frames cost the least. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

The first thing to ask yourself when planning on installing new windows is: Do you want a full-frame installation or a pocket installation?

Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has a great amount of deterioration. Full-frame installations involve more time and labor and will increase overall costs. A pocket installation entails installing a new window without replacing the frame. This means instead of removing the whole window and rebuilding it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window installer can help you decide which type of installation you need.

How We Choose the Best Window Installers in Meridian

EcoWatch is different from most reviewers since we evaluate these companies through a sustainability lens. We have evaluated the best window installation companies in Meridian primarily based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Since this is a guide for Meridian, we gave more points to companies that cover the city. There are certainly other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Meridian.

Work Quality

When choosing 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 more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another very important review factor. If most customers don't have nice things to say about their experience with a certain installer, you won't see it 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 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

Lastly, we like to see companies that have been in the industry for quite some time. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Meridian, CO Window Replacement FAQs

How much should window installation cost?

The typical cost of replacing a single window ranges from $450 to $650. There are several factors that influence the price, such as styles and sizes of windows, local labor costs, how energy-efficient the windows are, the number of windows, your property's location and the materials used in designing the windows.

What type of window is the best for energy efficiency?

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

Can you replace your own windows?

If you're handy and have the time and patience to do the job right, you may be able to install your own windows. But if you don't have the time or skills, we recommend getting a professional to do it for you.

When is the best time of year to replace windows?

While you can install windows any time of year, warmer weather is usually better for installing replacement windows. Additionally, the weather should be dry, as rain can make the installation harder.

Should I replace all my windows at the same time?

If your windows are more than 20 years old, you probably need to replace all of them. By that point, they are often less efficient, draftier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less time.
