How Installing Energy-Efficient Windows in Belleville Saves You Money

By upgrading to energy-efficient windows, you and your family can benefit in several ways, including:

• Decrease your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Belleville, that’s about 642 pounds per year on average.
• 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.
• Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Replacing your windows with energy-efficient models can help lower that amount, therefore saving you about 12% more on your bills.
• Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if your home is on the older side.

Estimated Cost of Window Replacement in Belleville

When looking into window installation, each company offers different services and prices. Let’s take a look at some typical costs and services.

How Much Do New Windows Cost?

Although the national average cost to replace one window is around $600, it can range from $200 to $1,200. This is because the cost of window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as the location of your property.

It’s also worth keeping in mind that energy-efficient windows will typically cost more upfront, but Energy Star estimates that switching out the windows on your Belleville home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you’ll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Requesting free quotes from several installers is the best way to find out which one will work best for your budget.

What Services do Window Installers Offer?

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

Full-frame installations are usually recommended when you want to change the style of your windows or your window has a lot of rot. With this service, your professionals will replace the whole window, including the sill, trim and frame. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

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 Belleville, the choice will mostly be based on the efficiency of your home and the condition of your existing frames.

Service Area

Because this is a guide for Belleville, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Belleville.

Work Quality

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

Customer Reviews

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

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers’ prices, we awarded 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 offer 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 installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
