How Installing Energy-Efficient Windows in Oakville Saves You Money

Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to make the switch:

  • Reduce your carbon footprint: By using less energy after you upgrade to Energy Star certified windows, you’ll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
  • Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Replacing your windows with energy-efficient models can help lower that amount, therefore saving you about 12% more on your bills.
  • 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: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Oakville

When researching window installation, each company provides different services and prices. Let’s go over some average costs and services.

How Much Do New Windows Cost?

The typical cost to install a single window is about $600 but can range anywhere from $200 to $1,200. How much it will cost is based on several factors, such as size, number of windows, the location of your home, type, material and more.

With windows, efficiency is one of the most important factors for many homeowners. Efficient 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 Oakville homeowners $376+ each year after replacing single-pane windows.

Costs will also vary based on the material you want for your window frames. Aluminum frames have the lowest price. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

There are typically two types of window replacement services: 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 noticeable rot. These installations are more involved and will increase the overall cost. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are on the simpler end and won’t cost as much, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

Your window installation company should be able to help you choose which type of installation you should get.

How We Choose the Best Window Installers in Oakville

EcoWatch reviews are different from most reviews because we assess 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

This one is self-explanatory, but we’ve chosen to highlight window installers that serve the Oakville area so you can find a quality window installation company near you.

Work Quality

We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer featured in our guide to ensure its technicians 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 super important review factor is customer feedback. If the majority of customers don’t have positive feedback about their service from a certain company, it won’t be featured on EcoWatch.

Cost

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

Warranty

As discussed, windows are a considerable investment, so you’ll want to make sure that investment is protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Due to Oakville’s climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Oakville window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Oakville, MO Window Replacement FAQs

What is the typical cost to replace windows?

The national average cost to install one window is around $600 but can range between $200 and $1,200, depending on several factors. The price is usually dependent on the size of the window, the type and material of the window and the location of your property. 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 several different kinds of windows you can get for your house, including slider windows, bay windows, double-hung and single-hung windows, casement windows, picture windows, transom windows and awning windows.

What do window installation companies do?

Window installation professionals visit your house to remove your old windows and replace them with new ones. Some providers install products made by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.

Should I replace all my windows at the same time?

If you’re upgrading your windows because of energy-efficiency, replacing all of your windows at once is the only way to see a noticeable difference. On the other hand, if you have just one or two windows that are damaged or leaky, you can replace just those.

How long does it usually take to install windows?

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