How Installing Energy-Efficient Windows in Ofallon Saves You Money

There are quite a few perks of switching to energy-efficient windows. Some reasons you may want to consider making the switch include the following:

  • Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Replacing your windows with energy-efficient models can help decrease that amount, therefore saving you about 12% more on your bills.
  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
  • Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if you have an older home.
  • Decrease your carbon footprint: In Ofallon, you can cut your indirect greenhouse gas emissions by about 763 pounds per year once you switch to energy-efficient windows.

Estimated Cost of Window Replacement in Ofallon

When looking into window installation, each company provides varying services and costs. Let's look at some average costs and services.

How Much Do New Windows Cost?

According to our market research, the average cost to replace a single window is around $600. However, window installation costs can range from $200 to $1,200 for each window. These amounts vary based on the specifics of your installation, including material, the location of your home, size, number of windows, type and more.

With windows, efficiency is one of the most important factors for most homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — especially during the summer and winter — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Ofallon homeowners $382+ per year after replacing single-pane windows.

Something else that influences the overall cost is the material you pick for your frame. Aluminum frames are typically the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

The first step when planning a window replacement is to decide whether you want a full-frame or pocket installation.

Full-frame installations require replacing the full window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has significant deterioration. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are simpler and won't carry as large a bill, but you can't do this kind of installment if you have any pre-existing rot or water damage.

Your window installer should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Ofallon

EcoWatch differs from other reviewers because we examine these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and ranked them using the following methodology:

Service Area

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

Work Quality

When installing new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand of window you get. 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

We analyzed trends in recent customer feedback to determine the companies with the highest rates of customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including quality of installation, warranty, quality of parts, cost, professionalism and more.

Cost

This one is a give-and-take: similar to most services, cheap window installers are not going to provide the most quality service. On the other hand, we want to ensure we're highlighting companies that offer a range of price and financing options so they're accessible to most homeowners.

Warranty

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

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

Ofallon, MO Window Replacement FAQs

How much should a window install cost?

The national average cost to install a window is about $600 but can range between $200 and $1,200, depending on a variety of factors. The price is typically influenced by the location of your property, the type and material of the window and the size of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

What are the kinds of windows?

The most common types of windows for homes include: bay windows, double-hung and single-hung windows, picture windows, awning windows, slider windows, casement windows and transom windows.

Can you install your own windows?

While it is possible to install your own windows, doing so is time-consuming and requires a lot of handiness. Hiring a professional can help ensure that the job is done properly and that you won't have to spend the time and effort to do it yourself.

When is it time to replace your windows?

Windows usually have a lifespan of 20 to 30 years, but anytime you notice damage on your windows, it's a good idea to have an expert take a look at them to determine if they are in need of a repair or replacement.

Should I replace all my windows at once?

If you want to get more efficient windows and save money on your energy bills, replacing all the windows at once is the only way to gain that benefit. On the other hand, if you have just one or two windows that are damaged or drafty, you can replace just those.
