How Installing Energy-Efficient Windows in Westmont Saves You Money
There are several benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch include the following:
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
- Save on electricity bills: Since energy-efficient windows reduce the amount of energy used to heat or cool your home, they can help you save around $300 annually on your energy bills in Westmont.
- Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
- Decrease your carbon footprint: By using less energy once upgrading to Energy Star certified windows, you'll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Westmont
Let's take a look at the cost of window replacement and the types of services offered by installers.
How Much Do New Windows Cost?
According to our research, the typical cost of installing a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. This is due to the fact that window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as where your property is located.
It's also worth noting that energy-efficient windows will typically cost more initially, but Energy Star estimates that upgrading the windows on your Westmont 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. How much you'll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
The cost of your window installation will also vary based on the kind of window material you choose for the frames. Wood windows are usually the most expensive, although it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
The first step when planning a replacement is to think about whether you should get a full-frame or pocket installation.
Full-frame installations entail replacing the complete window, including the frame, sill and trim. You most likely need a full-frame installation when you want a new style or your window has noticeable damage or rot. Full-frame installations are more involved and will increase the total cost. Pocket installations are on the simpler end and won't carry as large a bill because they entail simply replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.
If you're not sure which kind of window installation service you need, your installer can help you out. Generally, the choice depends on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Westmont
In our search to find the most reliable, eco-friendly window installers in Westmont, the EcoWatch Reviews team evaluated many companies before settling on these. Along with energy efficiency, we reviewed each installer and ranked them using the following methodology:
Service Area
Because this is a guide for Westmont, we paid more attention to companies that provide services to the city. There are other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Westmont.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each company on this list to make sure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don't have nice things to say about their experience with a certain installer, you won't see it featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs as low as 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 offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Westmont's climate, homeowners will want to mitigate low efficiency, water damage and rot. We factored in local experience to reflect the ability of Westmont window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Westmont, IL Window Replacement FAQs
What is the average cost to replace windows in a home?
The national average cost to install a single window is around $600 but can range between $200 and $1,200, based on a few different factors. The price is often influenced by the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the most common kinds of replacement windows?
The most common kinds of windows for homes are casement windows, double-hung and single-hung windows, slider windows, bay windows, transom windows, awning windows and picture windows.
Can I replace 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 know-how, we recommend hiring a professional.
How long does window installation take?
Because a window takes about 30 minutes to install, about 16 windows can be installed during a typical 8-hour work day.
Should I replace my windows all at the same time?
If your windows are more than 20 years old, you probably need to replace all of them. At that point, they are typically less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.
