Why you can trust EcoWatch
Although clean 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 considerable impact on home energy conservation. If you have traditional, outdated windows, your HVAC system could be working extra hard to heat or cool your house. This means higher electricity bills.
Replacement windows improve the insulation in your home, not only making you more comfortable during extreme temperatures, but also saving you some money and helping the environment.
Unlike other sites, EcoWatch ranks window companies based on energy efficiency while also balancing cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Flora 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 change are the following:
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
- Save on power bills: Once you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% because you'll require less energy to heat or cool your home.
- Decrease your carbon footprint: By using less energy after upgrading to Energy Star certified windows, you'll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.
Estimated Cost of Window Replacement in Flora
Each window installer offers various services and has different costs based on several factors.
How Much Do New Windows Cost?
According to our research, the average cost to install a single window is around $600. However, window installation costs can range from $200 to $1,200 a window. These numbers vary based on specific characteristics of your installation, including number of windows, the location of your home, material, size, type and more.
Whether or not you want to install energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $302 a year on your energy bills in Flora.
The cost of your window installation will also vary depending on the kind of material you choose for the frames. Wood windows are typically the most expensive, although it depends if they are solid 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?
There are typically two kinds of window installation services: full-frame and pocket installations.
Full-frame installations involve replacing the complete window, including the sill, frame and trim. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable rot or deterioration. Full-frame installations are more involved and will raise the total cost. Pocket installations are simpler and won't cost as much, as they entail simply replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.
If you're still debating which type of installation you should get, you can consult with your provider and get their advice. The choice mostly depends on how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Flora
In our search to make your home improvements easier and more eco-friendly in Flora, the EcoWatch team evaluated many companies before deciding on these. Along with energy efficiency, we reviewed each installer and assigned rankings using the following methodology:
Service Area
Because this is a guide for Flora, we paid more attention to companies that serve the city. There are other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Flora.
Work Quality
When selecting new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand you choose. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another super important review factor. If most customers don't have positive 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: as with most services, cheap window companies are not going to provide the highest quality service. Still, we want to ensure we're highlighting companies that provide a range 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 provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Flora's climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Flora window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Flora, IL Window Replacement FAQs
What is the average cost to install windows?
The national average cost to install one window is around $600 but can range between $200 and $1,200, based on a variety of factors. The price is generally 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 initially but can save you a decent amount of money a year in energy bills.
What are the most common types of replacement windows?
The most common types of windows for homes are bay windows, double-hung and single-hung windows, awning windows, casement windows, picture windows, transom windows and slider windows.
Do you really have to use a window installation company?
You should use a window installation professional whenever you want to replace your windows. Installing windows is a involved process that can be difficult and time-consuming, so it's best left to the professionals.
How do you know it's time to replace your windows?
Windows usually have a lifespan of 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have an expert take a look at them to see if they are in need of a repair or replacement.
Should I replace all my windows at once?
If your windows are greater than 20 years old, you most likely need to replace all of them. At that point, they are typically less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.
