How Installing Energy-Efficient Windows in Avon Saves You Money
There are quite a few perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the switch are the following:
- Save on power bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of residential energy use. Installing energy-efficient windows can help lower that amount, which helps you save $446 a year on your bills.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Reduce your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 147 pounds per year on average.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help raise the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Avon
Each window installer offers varying services and has different price points depending on several factors.
How Much Do New Windows Cost?
Though the average of installing a single window is around $600, it can range from $200 to $1,200. This is because of the fact that the cost of window installations depend on several factors specific to your home, including the size, material and number of windows you need to install, as well as where your property is located.
It's important to remember that windows with the best efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save Avon homeowners $446+ a year when replacing single-pane windows.
We advise getting free quotes from multiple window installers to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
Generally, there are two types of window installation services companies offer: full-frame and pocket installations.
Full-frame installations involve replacing the complete window, including the sill, frame and trim. 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 full-frame installations are more involved, they will increase the total cost. Pocket installations are on the simpler end and won't cost as much because they involve simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may have to get a full-frame installation instead.
If you're hiring a reputable window installation company, your company will be able to recommend the best type for your project. In Avon, 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 Avon
EcoWatch reviews are different from most reviews, as we assess these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and ranked them using the following methodology:
Service Area
Since this is a guide for Avon, we gave more points to companies that provide services to the city. There are other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Avon.
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 featured in our guide to make sure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have good things to say about their service from a certain window installation company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window installation companies won't always provide the highest quality service. Still, 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
Protecting your investment in new windows is important. For that reason, window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
