Why you can trust EcoWatch
A guide on the top window installation companies in Freeport may not seem like the most compelling article on EcoWatch, but trust us, windows impact your life more than you might realize. If your house has old or damaged windows, your HVAC system could be working extra hard to heat or cool your house. This means spending more on energy bills.
That’s also bad for the environment, as the additional energy required by old windows increases your carbon footprint.
So if you’re building a new home, renovating or replacing your windows in Freeport, this is the best place to get started.

How Installing Energy-Efficient Windows in Freeport Saves You Money
By upgrading to energy-efficient windows, you and your family can enjoy several benefits, such as:
- Reduce your carbon footprint: In Freeport, you can cut your indirect greenhouse gas emissions by about 307 pounds per year when you upgrade to energy-efficient windows.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help increase the value of your property if you decide to sell.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Save on energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of energy use in your home. Switching to energy-efficient windows can help reduce that amount, which helps you save more on your bills.
Estimated Cost of Window Replacement in Freeport
Each window installation company provides various services and has different prices based on several factors.
How Much Do New Windows Cost?
On average, Freeport homeowners can expect their replacement window installations to range from $250 to $1,200. The most common installations sit at approximately $600. But prices vary considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations and replacements, which will add extra costs to your project.
With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more upfront, 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, purchasing certified energy-efficient windows can save Freeport homeowners $283+ each year after 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 generally 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 step when considering a window replacement is to decide whether you need a full-frame or pocket installation.
Full-frame installations involve replacing the full window, including the sill, trim and frame. Full-frame installations are necessary when you want a new style or your window has considerable deterioration. Because these installations are more involved, they will raise the total cost. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you will most likely need a full-frame installation instead.
Your window installation company should be able to help you decide which type of installation you need.

How We Choose the Best Window Installers in Freeport
In our search to make your home improvements easier and more eco-friendly in Freeport, EcoWatch chose the above companies as the top window installation companies in the city. We have assessed the top window replacement companies in Freeport mainly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Because this is a guide for Freeport, we only included companies that cover the city. There are other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Freeport.
Work Quality
When selecting new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand you opt for. 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
We analyzed trends in recent customer feedback to determine the companies with the highest rates of 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 cost, professionalism, quality of parts, warranty, quality of installation and more.
Cost
This one is a give-and-take: similar to most services, cheap window installers may not provide the highest quality service. Still, we want to make sure 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. 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 Freeport’s climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Freeport window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
