How Installing Energy-Efficient Windows in Frontenac Saves You Money

By upgrading to energy-efficient windows, you and your family can enjoy several benefits, such as:

  • 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 Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
  • Save money on power bills: Since energy-efficient windows lower how much energy you need to heat or cool your home, the switch can help you save around $328 annually on your energy bills in Frontenac.
  • Reduce your carbon footprint: In Frontenac, you can reduce your indirect greenhouse gas emissions by about 763 pounds per year when you install energy-efficient windows.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.

Estimated Cost of Window Replacement in Frontenac

Let's go over the cost of installing new windows and the kinds of services you may need for your home.

How Much Do New Windows Cost?

According to our market research, the average cost of installing a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. How much it will cost depends on several factors, including type, number of windows, size, the location of your home, material and more.

It's important to note that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Frontenac homeowners $328+ a year when replacing single-pane windows.

We recommend getting free quotes from multiple window installers to find the right windows and the company that works best for your budget.

What Services do Window Installers Offer?

The first step when planning a window installation is to think about whether you need a full-frame or pocket installation.

Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has a great amount of damage. Full-frame installations are more time-consuming and 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. But, if the frame has any damage or rot, you will likely need a full-frame installation instead.

If you're unsure which type of window installation service you need, your installer should be able to advise you. 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 Frontenac

In our hunt to find the most reliable, eco-friendly window installers in Frontenac, the EcoWatch team assessed many companies before deciding on these. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings using the following methodology:

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 a quality 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

Another self-explanatory yet very important review factor is customer feedback. If most customers don't have positive things to say about their experience with a certain company, it won't be featured on EcoWatch.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers' prices, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

Protecting your investment in new windows is important to many homeowners. That's why window installation companies that provide lengthy warranties for products, parts and labor 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 experience earn higher rankings by our standards. We like to see at least ten years of experience.

Frontenac, MO Window Replacement FAQs

What is the average cost to install windows in a home?

The average cost of installing a single window can range from $450 to $650. There are many factors that influence the cost, which include the materials used in designing the windows, your property's location, local labor costs, the number of windows, styles and sizes of windows and how energy-efficient the windows are.

What are the kinds of windows?

There are various kinds of windows you can get for your home, such as slider windows, bay windows, picture windows, transom windows, awning windows, double-hung and single-hung windows and casement windows.

Do I really need to use a window installation company?

Unless you're handy and have the tools needed to replace your own windows, we recommend hiring the pros. The process of installing windows is complex and can take anywhere from four to six hours for one window. Although it's tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and safer alternative.

How long does window installation usually take?

Each window takes around 30 minutes to install based on the kind of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
