How Installing Energy-Efficient Windows in Cottage Lake Saves You Money

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

• Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Installing energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.
• Protect your investment: If you have a relatively old home, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
• 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.
• Decrease your carbon footprint: By using less energy once you upgrade to Energy Star certified windows, you’ll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Cottage Lake

When researching window installation, each company provides varying services and costs. Let’s take a look at some typical costs and services.

How Much Do New Windows Cost?

Although the national average cost to replace one window is about $600, it can range anywhere from $200 to $1,200. Costs will differ significantly based on your location, the quality of your products, the current condition of your home and the number of windows you need. A lot of window companies also offer door installations and other add-ons like coating, shutters, baths and more. These extra services will increase your overall project costs.

It’s important to note that windows with the best efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Cottage Lake homeowners $366+ a year when replacing single-pane windows.

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

What Services do Window Installers Offer?

The first question to ask yourself when getting new windows is: Do you want a full-frame installation or a pocket installation?

A full-frame installation is a total window replacement. This service involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, like insulation and drip edges, which increase the overall cost of the project. It’s also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.

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

How We Choose the Best Window Installers in Cottage Lake

EcoWatch is different from most reviewers because we examine these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Cottage Lake and assigned rankings using the following methodology:

Service Area

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

Work Quality

When installing new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand of window you opt for. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

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

Cost

This one is a give-and-take: as with most services, cheap window installers are not going to provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that provide a spectrum of price and financing options so they’re accessible to most homeowners.

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 installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
