How Installing Energy-Efficient Windows in Oakville Saves You Money

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

  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
  • Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.
  • Save on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Replacing your windows with energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
  • Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can reduce your carbon footprint by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Oakville

Each window installation company offers various services and has varying price points based on several factors.

How Much Do New Windows Cost?

On average, Oakville homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost sits at about $600. How much it will cost you varies depending on several factors, like number of windows, the location of your home, type, size, material and more.

With windows, efficiency is one of the most important factors for most homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Oakville homeowners $335+ a year after replacing single-pane windows.

Another factor that affects the overall cost is the material you pick for your frame. Aluminum frames are generally the least expensive and are sturdy and relatively maintenance-free, 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 question to ask yourself when planning to replace your windows is: Should you get a full-frame installation or a pocket installation?

Full-frame installations entail replacing the total window, including the trim, frame and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable deterioration. Because full-frame installations are more involved, they will increase the total cost. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any damage or rot, you will most likely need a full-frame installation instead.

Your window installation company can recommend the best type for your project. In Oakville, the decision will mostly be influenced by the efficiency of your home and the age of your existing frames.

How We Choose the Best Window Installers in Oakville

The EcoWatch Reviews team is different from other reviewers, as we're examining these companies through a sustainability lens. Along with energy efficiency, we reviewed window companies all across the state and ranked them based on the following methodology:

Service Area

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

Work Quality

We're willing to bet that you're looking for a company to 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

We analyzed trends in recent customer feedback to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including professionalism, cost, quality of parts, quality of installation, warranty and more.

Cost

This one is a give-and-take: similar to other services, cheap window installation companies won't always provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that provide a variety 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 be certain that investment is well protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Oakville's climate, homeowners will want to mitigate low efficiency, water damage 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

How much does a window install cost?

The national average cost to replace a window is around $600 but can range between $200 and $1,200, depending on several factors. The price is often dependent on the size of the window, the location of your property and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.

Which type of window is the best?

A window's energy efficiency is affected by a number of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.

What do window installers do?

Window installers go to your home to remove your old windows and replace them with new ones. Some companies install products distributed by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is finished.

How long does window installation typically take?

Because the average installation time is 30 minutes per window, about 16 windows can be installed in an 8-hour work day.

When is the best time of year to replace windows?

Replacement windows can be installed at any time, but autumn might be the best season. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into the home, so the temperature outside isn't necessarily a big factor. Most importantly, the weather should be dry.
