No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Although environmentally friendly energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your house's efficiency can also have a large impact on home energy conservation. If you have traditional, outdated windows, your AC or heating system could be working overtime to heat or cool your house. This means spending more on electricity bills.

Thankfully, saving you money with efficient windows also aligns with our goals of reducing energy usage for the environment.

So if you're constructing a new home, renovating or updating your windows in Niagara, this is the best place to get started.

How Installing Energy-Efficient Windows in Niagara Saves You Money

Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to consider making the switch:

  • Save on power bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Replacing your windows with energy-efficient models can help reduce that amount, therefore saving you about 12% more on your bills.
  • Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out harmful UV rays.
  • Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
  • Reduce your carbon footprint: By using less energy once upgrading to energy-efficient windows, you'll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Niagara

Each window installation company offers varying services and has different price points based on a few factors.

How Much Do New Windows Cost?

According to our research, the national average cost to install a single window is about $600. However, window replacement costs can range from $200 to $1,200 for each window. These amounts vary depending on specific characteristics of your installation, including material, size, number of windows, type, the location of your home and more.

With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — particularly during the winter — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Niagara homeowners $335+ a year after replacing single-pane windows.

We advise requesting free quotes from multiple window installers to find the one that works best for you.

What Services do Window Installers Offer?

There are typically two kinds of window installation services: full-frame and pocket installations.

A full-frame installation replaces the total window, including the windowsill, frame, trim and the window panes. As this kind of installation is more involved, it will be more expensive than a pocket installation. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations more simple and affordable. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

Your window installation company will be able to help you figure out what's best for your needs. In Niagara, the decision will mostly depend on the age of your home and if there's any damage. Wood can decay if not properly maintained over the years, so it's a good idea to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Niagara

The EcoWatch Reviews team differs from other reviewers since we examine these companies through a sustainability lens. Along with energy efficiency, we reviewed window companies all across the state and assigned rankings based on the following methodology:

Service Area

Since this is a guide for Niagara, we only included companies that serve the city. There are other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Niagara.

Work Quality

When picking new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand of window you choose. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

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

Cost

This one is a give-and-take: as with most services, cheap window installation companies won't always provide the most quality service. On the other hand, we want to ensure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.

Warranty

As discussed previously, windows are a sizable investment, so you'll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have been in the industry for a while. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Niagara, NY Window Replacement FAQs

How much does window installation cost?

The national average cost of installing one window is about $600 but can range from $200 to $1,200, depending on several factors. The price is generally dependent on the size of the window, the type and material of the window and the location of your property. 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 types of windows?

There are several different kinds of windows you can get for your house, including slider windows, double-hung and single-hung windows, picture windows, bay windows, awning windows, transom windows and casement windows.

What do window installers do?

Window installation companies cover the entire process — from replacing old windows with brand new ones to cleaning up after the installation. Additionally, a lot of companies offer window manufacturing, customization and repairs.

How often do you need to replace your windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may need to be replaced.

Should I replace all my windows at the same time?

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