How Installing Energy-Efficient Windows in Pontiac Saves You Money

When you switch to energy-efficient windows, you may see a few benefits, such as:

  • Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
  • 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 fading of your furniture, carpet and other valuables.
  • Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Upgrading to energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.
  • Reduce your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by about 642 pounds.

Estimated Cost of Window Replacement in Pontiac

Windows come in varying purposes, shapes and styles, so costs and services will vary greatly depending on several factors. Below, we go over the typical cost and services that you'll find from window replacement companies.

How Much Do New Windows Cost?

On average, homeowners in Pontiac can anticipate that most window installations will cost between $250 and $1,200, with the average cost at about $600. These numbers vary based on specific characteristics of your installation, like the location of your home, size, material, type, number of windows and more.

It's also worth keeping in mind that energy-efficient windows will usually cost more upfront, but Energy Star estimates that upgrading the windows on your Pontiac home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

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

What Services do Window Installers Offer?

The first step of a window replacement is to figure out whether you should get a full-frame or pocket installation.

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

If you're still trying to decide which kind of installation you should get, you can ask your provider and get their recommendation. The choice mostly is influenced by how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Pontiac

EcoWatch reviews are different from most reviews, as we assess these companies through a sustainability lens. We've decided to review the top window installation companies in Pontiac mostly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

We're certain that you're looking for a company to do a great job installing windows. We've vetted each installer featured in our guide to ensure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including professionalism, quality of installation, quality of parts, warranty, cost and more.

Cost

Cheaper windows certainly don't 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 awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed, windows are a sizable investment, so you'll want to make sure that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Pontiac, IL Window Replacement FAQs

How much does window installation cost?

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

Which kind of window should I get?

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. To be sure you'll get the most energy-efficient windows, look for models that have the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.

Do I really need to use a window installation company?

Unless you have experience with home improvement projects and have all of the necessary tools to replace your own windows, we recommend hiring a professional. 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 safer option.

When is the best time of year to replace windows?

Replacement windows can be installed during any season, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your house, so the temperature outside doesn't necessarily matter that much. What's most important is that the weather should be dry.

Should I replace all my windows at the same time?

If you want to get more efficient windows and save money on your energy bills, replacing all of the windows together is the only way to see a noticeable difference. On the other hand, if you have just one or two windows that are broken or drafty, you can replace just those.
