How Installing Energy-Efficient Windows in Foster Saves You Money
There are several perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch include the following:
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
- Save on energy bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of energy use in your home. Upgrading to energy-efficient windows can help lower that amount, which helps you save some money on your bills.
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
- Decrease your carbon footprint: By using less energy after switching to energy-efficient windows, you'll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Foster
Let's take a look at the cost of installing new windows and the types of services offered by installers.
How Much Do New Windows Cost?
Though the national average of installing one window is around $600, it can range anywhere from $200 to $1,200. But costs differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations, which have a higher price tag.
Keep in mind that energy-efficient windows may come at a higher price point, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.
How much your window installation costs will also vary based on the kind of material you choose for the frames. Wood windows are typically the most expensive, although it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
In regard to window replacements, there are typically two types that your installer will offer: full-frame and pocket installations.
Full-frame installations entail replacing the full window, including the frame, trim and sill. You most likely need a full-frame installation when you want a new style or your window has considerable rot or deterioration. Because full-frame installations are more involved, they will increase overall costs. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any damage or rot, you will likely need a full-frame installation instead.
If you're unsure which kind of window installation service you should get, your installer should be able to assist you. Generally, the decision is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Foster
In our search to find the most reliable, eco-friendly window installers in Foster, the EcoWatch Reviews team landed on the above companies as the top window installation companies in the city. We've reviewed the top window installation companies in Foster mostly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Because this is a guide for Foster, 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 Foster.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each installer in our guide to make sure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have positive things to say about their service from a certain company, you won't see it featured on EcoWatch.
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 providers' prices, we awarded 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
Because of Foster's climate, homeowners need to be wary of low efficiency, water damage and rot. We factored in local experience to reflect the ability of Foster window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Foster, IL Window Replacement FAQs
What is the average cost to install new windows in a home?
The average cost to replace one window can range from $450 to $650. There are a variety of factors that affect how much it costs, such as the number of windows, styles and sizes of windows, local labor costs, the materials used in designing the windows, how energy-efficient the windows are and your property's location.
Which type of window is the best?
A window's energy efficiency depends on several factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.
Can I install my 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. However, if you don't have the time or skills, we recommend getting a professional to do it for you.
How long does it take to install windows?
Since the average installation time of a window is 30 minutes, about 16 windows can be installed during an 8-hour work day.
Should I replace all my windows at once?
If your windows are greater than 20 years old, it's probably time to replace all of them. By that point, they are usually less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
