Oakville Window Cost Calculator

Calculate how much you can expect to pay for window installation and replacement in Oakville, MO using our customized window cost calculator.

Estimated Window Cost:
161 homeowners have requested a free estimate in the last 3 days.

Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.

How Installing Energy-Efficient Windows in Oakville Saves You Money

By switching to energy-efficient windows, you and your family can take advantage of several benefits, including:

  • Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Save money on energy bills: Once you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll use less energy to heat or cool your house.
  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if you have an older home.
  • Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.

Estimated Cost of Window Replacement in Oakville

When researching window installation, each company offers varying services and costs. Let’s go over some average costs and services.

How Much Do New Windows Cost?

The national average cost to replace a single window is about $600 but can range from $200 to $1,200. These amounts are based on the specifics of your installation, such as the location of your home, size, type, number of windows, material and more.

Keep in mind that energy-efficient windows may have a higher price, 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 per year when you replace double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.

Getting free quotes from multiple companies is the best way to find out which one is right for you.

What Services do Window Installers Offer?

In general, there are two types of window installation services companies offer: full-frame and pocket installations.

Full-frame installations entail replacing the complete window, including the sill, frame and trim. You most likely need a full-frame installation when you want to change the style of your windows or your window has significant rot or deterioration. Because these installations are more involved, they will raise overall costs. A pocket installation entails replacing a window without replacing the frame. This means instead of taking out the whole unit and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company should be able to help you figure out what’s best for your needs. In Oakville, the decision will mostly be based on how old your home is and if there’s any damage. Wood can decay if not maintained properly over the years, so it’s a good idea to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Oakville

EcoWatch reviews are different from most reviews because we look at these companies through a sustainability lens. We’ve decided to review the best window replacement companies in Oakville primarily based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows have been shown to lower electricity 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 installation companies that serve Oakville so you can find a quality window installation company near you.

Work Quality

We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer included in our guide to make sure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent customer feedback to find the companies with the most customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including warranty, quality of installation, cost, quality of parts, professionalism and more.

Cost

This one is a give-and-take: similar to most services, cheap window installation companies are not going to provide the most quality service. Still, 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. For that reason, 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 been in the industry for quite some time. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Oakville, MO Window Replacement FAQs

How much should a window install cost?

The national average cost to replace a single window is about $600 but can range from $200 to $1,200, depending on several factors. The price is usually influenced by the location of your property, the size of the window and the type and material 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 types of replacement windows?

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

What do window installation companies do?

Window installation professionals go to your property to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others install their own windows. The installer will also clean up after the installation is complete.

Should I replace all my windows at once?

If your windows are greater than 20 years old, you probably need to replace all of them. At that point, they are often less efficient, leakier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less time.

How long does window installation generally take?

Each window takes around 30 minutes to install depending on the type of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
