How Installing Energy-Efficient Windows in Algonquin Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to take the plunge and make the switch:
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
- 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.
- Save on electricity bills: Because energy-efficient windows lower how much energy you need to heat or cool your home, the switch can help you save around $317 annually on your energy bills in Algonquin.
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Algonquin, that’s about 449 pounds per year on average.
Estimated Cost of Window Replacement in Algonquin
Let’s take a look at the cost of window installation and the types of services offered by installers.
How Much Do New Windows Cost?
According to our market research, the national average cost to install a single window is about $600. However, window replacement costs can range from $200 to $1,200 a window. How much it will cost depends on several factors, such as size, type, the location of your home, number of windows, material and more.
With windows, efficiency is one of the most important factors for many homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — especially during the summer and winter — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Algonquin homeowners $317+ a year after replacing single-pane windows.
Getting free quotes from multiple providers is the best way to figure out which one is right for you.
What Services do Window Installers Offer?
The first question to ask yourself when considering a window replacement is: Do you want a full-frame installation or a pocket installation?
Full-frame installations entail 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 noticeable rot. Because these installations are more involved, they will raise overall costs. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any rot or deterioration, you will most 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 Algonquin
The EcoWatch Reviews team differs from most reviewers, as we assess these companies through a sustainability lens. We have reviewed the best window replacement companies in Algonquin primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for Algonquin, we paid more attention to companies that cover the city. There are certainly other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Algonquin.
Work Quality
When it comes to new windows, the quality and range of services can often play just as important of a role in insulation and performance as the type of window you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have good feedback about their service from a certain company, it won’t be featured on EcoWatch.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important. That’s why window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Algonquin’s climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Algonquin window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
