    How Installing Energy-Efficient Windows in Ottawa Saves You Money

    Switching to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more details about how upgrading your windows could help you:

    • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
    • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if you have an older home.
    • Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Ottawa, that’s about 642 pounds per year on average.
    • Save on energy bills: After you switch 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.

    Estimated Cost of Window Replacement in Ottawa

    Let’s take a look at the cost of window replacement and the types of services you may need for your home.

    How Much Do New Windows Cost?

    Even though the average cost to replace one window is around $600, it can range anywhere from $200 to $1,200. How much it will cost is based on several factors, such as number of windows, type, material, the location of your home, size and more.

    It’s also worth noting that energy-efficient windows will typically cost more initially, but Energy Star predicts that upgrading the windows on your Ottawa home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

    How much your window installation costs will also vary depending on the type of window material you choose for the frames. Wood windows are typically the most expensive, although it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.

    What Services do Window Installers Offer?

    In regard to window installations, there are generally two kinds that your installer will have: full-frame and pocket installations.

    Full-frame installations involve replacing the complete 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 considerable rot or deterioration. Because these installations are more involved, they will raise the total cost. A pocket installation means replacing a window without removing the complete frame, which is generally cheaper than a full-frame installation.

    Your window installer can help you choose which type of installation you need.

    How We Choose the Best Window Installers in Ottawa

    EcoWatch reviews are different from most reviews because we look at these companies through a sustainability lens. We’ve decided to assess the top window replacement companies in Ottawa mostly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

    Service Area

    This one is self-explanatory, but we’ve chosen to highlight window installers that serve Ottawa so you can find the best 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 company featured on this list to ensure its technicians are well-qualified and that the company has received tons 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 consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including warranty, cost, quality of parts, quality of installation, professionalism and more.

    Cost

    Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers’ prices, we awarded 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. For that reason, window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

    Years of Experience

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

    Ottawa, IL Window Replacement FAQs

    How much does a window install cost?

    The national average cost of installing a window is around $600 but can range from $200 to $1,200, depending on a variety of factors. The price is usually influenced by the type and material of the window, the size of the window and the location of your property. Also, keep in mind 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?

    The most common kinds of windows for homes include: bay windows, double-hung and single-hung windows, slider windows, picture windows, transom windows, awning windows and casement windows.

    Can you install your own windows?

    Even though you can install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Hiring a professional can help ensure that the job is done properly and that you won’t have to spend the time and effort to do it yourself.

    Should I replace my windows all at once?

    If you want to get more efficient windows and save money on your energy bills, replacing all the windows at once is the only way to see a noticeable difference. However, if you have just a few windows that are damaged or leaky, you can replace just those.

    How long does window installation typically take?

    Because a window takes about 30 minutes to install, about 16 windows can be installed during an 8-hour work day.
