How Installing Energy-Efficient Windows in Helvetia Saves You Money

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

  • Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its real estate value.
  • 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 your furniture, carpet and other valuables from fading.
  • Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Switching to energy-efficient models can help lower that number, therefore saving you about 12% more on your bills.
  • Reduce your carbon footprint: In Helvetia, you can reduce your indirect greenhouse gas emissions by about 642 pounds per year once you switch to energy-efficient windows.

Estimated Cost of Window Replacement in Helvetia

When researching window installation, each company provides different services and costs. Let's take a look at some typical costs and services.

How Much Do New Windows Cost?

According to our research, the typical cost of replacing a single window is around $600. However, window installation costs can range from $200 to $1,200 a window. But costs will vary considerably based on the quality of your products, your location, the number of windows you need and the current condition of your home. A lot of window companies also offer door installations and other add-ons like coating, shutters, baths and more. Additional services will increase your overall project costs.

With windows, efficiency is one of the most important factors for most homeowners. High efficiency windows may cost more off the bat, 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, purchasing certified energy-efficient windows can save Helvetia homeowners $313+ each year after replacing single-pane windows.

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

What Services do Window Installers Offer?

The first thing to ask yourself when getting new windows is: Should you get a full-frame installation or a pocket installation?

A full-frame installation is a replacement of the full window. It involves taking out the old window, the sill, and the exterior and interior trim. It also involves other materials, like insulation and drip edges, which raise the overall cost of the project. It's also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation entails installing a new window without replacing the frame. This means instead of tearing out the whole window and rebuilding it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.

If you're hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Helvetia, the decision will mostly depend on how much damage there is currently and the condition of your existing frames.

How We Choose the Best Window Installers in Helvetia

EcoWatch is different from other reviewers, as we evaluate these companies through a sustainability lens. We've assessed the best window installers in Helvetia primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve the Helvetia area so you can find the right window installation company near you.

Work Quality

When it comes to new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand you opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent online reviews to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including quality of parts, warranty, professionalism, quality of installation, cost and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing the prices of providers, we gave higher scores 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 with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Helvetia, IL Window Replacement FAQs

What is the typical cost to install new windows?

The typical cost to replace a window can range between $450 and $650. There are a variety of factors that influence the cost, such as how energy-efficient the windows are, the number of windows, local labor costs, styles and sizes 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 will be more efficient than single-pane windows and windows that don't open are more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification — they're certified energy-efficient by the U.S. Department of Energy.

Can I install my own windows?

If you're handy and have experience with similar home improvement projects, it's possible to install your own windows. However, if you don't have the time or skills, we recommend getting a professional to do it for you.

What time of year is a good time to replace my windows?

Replacement windows can be installed during any season, but autumn might be best. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into the home, so the temperature outside isn't necessarily a big factor. What's most important is that the weather should be dry.

Should I replace all my windows at once?

If your windows are more than 20 years old, you most likely need to replace all of them. By that point, they are typically less efficient, draftier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
