How Installing Energy-Efficient Windows in Belvidere Saves You Money

Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to think about making the switch:

  • Protect your investment: If you have a relatively old home, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
  • Decrease your carbon footprint: In Belvidere, you can reduce your indirect greenhouse gas emissions by about 449 pounds per year after you upgrade to energy-efficient windows.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
  • Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of residential energy use. Switching to energy-efficient windows can help lower that amount, which helps you save $318 a year on your bills.

Estimated Cost of Window Replacement in Belvidere

When looking into window installation, each company provides different services and prices. Let's go over some typical costs and services.

How Much Do New Windows Cost?

Although the typical of replacing a single window is about $600, it can range from $200 to $1,200. How much it will cost you varies depending on several factors, including type, size, material, the location of your home, number of windows and more.

Whether or not you want energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $318 a year on your energy bills in Belvidere.

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

What Services do Window Installers Offer?

In regard to window replacements, in general there are two kinds that your provider will offer: full-frame and pocket installations.

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has significant deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.

If you're hiring a reputable window installation company, your company can advise you on the best type for your project. In Belvidere, the choice will mostly be influenced by the efficiency of your home and the age and condition of your existing frames.

How We Choose the Best Window Installers in Belvidere

EcoWatch reviews differ from most reviews because we're examining these companies through a sustainability lens. We have evaluated the top window installers in Belvidere mainly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Because this is a guide for Belvidere, we gave more points to companies that provide services to the city. There are certainly other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Belvidere.

Work Quality

When selecting new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand you opt for. 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 very important review factor is customer feedback. If the majority of customers don't have nice things to say about their service from a certain window installation company, it won't be featured on EcoWatch.

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 points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

Protecting your investment in new windows is important. That's why window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Belvidere, IL Window Replacement FAQs

How much should a window install cost?

The average cost to install a window ranges from $450 to $650. There are many factors that affect how much it costs, which include the materials used in designing the windows, local labor costs, the number of windows, how energy-efficient the windows are, styles and sizes of windows and your property's location.

Which kind of window is the best?

A window's energy efficiency depends on a number of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.

When do I need to use a window installation company?

Unless you have home repair skills and have the time needed to replace your own windows, we recommend hiring a professional installer. The window installation process is complicated and can take anywhere from four to six hours for a single window. Although it's tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and much safer option.

When is the best time of year to replace windows?

While you can install windows any time of year, warmer weather is often better for replacing windows. In addition, it shouldn't be raining, as rain can make the installation more difficult.

Should I replace my windows all at once?

If you want to get more efficient windows and save money on your energy bills, replacing all your windows at once is the only way to see a noticeable difference. However, if you have just a few windows that are broken or leaky, you can replace just those.
