How Installing Energy-Efficient Windows in Southbury Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more ways switching out your windows could help you:
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Save on energy bills: Because energy-efficient windows decrease the amount of energy used to heat or cool your home, the switch can help you save about $420 annually on your energy bills in Southbury.
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Southbury, that's about 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 increase the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Southbury
When looking into window installation, each company provides varying services and costs. Let's look at some typical costs and services.
How Much Do New Windows Cost?
Typically, Southbury homeowners can expect their window replacements to range from $250 to $1,200. The average cost sits at around $600. This is due to the fact that the cost of window installations are based on several factors specific to your home, such as the size, material and number of windows you need to replace, as well as where your property is located.
With windows, efficiency is one of the most important factors 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 provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Southbury homeowners $420+ a year after replacing single-pane windows.
Something else that influences the overall cost is the material you pick for your frame. Aluminum frames are generally the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
In general, there are two kinds of window replacement services companies provide: full-frame and pocket installations.
Full-frame installations are necessary when you want to change the style of your windows or your window has significant deterioration. With this service, your installers will replace the whole window, including the frame, sill and trim. Pocket installations are on the simpler end and won't carry as large a bill 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 not sure which kind of window installation service you need, your installer can assist you. In general, the decision is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Southbury
In our hunt to make your home improvements easier and more eco-friendly in Southbury, the EcoWatch Reviews team evaluated dozens of companies before deciding on these. We've evaluated the best window replacement companies in Southbury 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 electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve the Southbury area so you can find the right window installation company near you.
Work Quality
When selecting new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand of window you choose. We do rate window installers higher 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. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including cost, warranty, quality of installation, professionalism, quality of parts and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a significant investment, so you'll want to be certain that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for quite some time. Window installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Southbury, CT Window Replacement FAQs
What is the average cost to install windows in a home?
The national average cost of installing a single window is about $600 but can range from $200 to $1,200, depending on a few different factors. The price is usually dependent on 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 upfront but can save you a decent amount of money a year in energy bills.
What type of window is the most energy-efficient?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — this means they're certified energy-efficient by the U.S. Department of Energy.
What services do window installation companies do?
Window installation professionals cover the entire process — from replacing old windows with new ones to cleaning up afterward. In addition, some companies offer window manufacturing, customization and repairs.
How long does it typically take to install windows?
Because the average installation time of a window is 30 minutes, about 16 windows can be installed in an 8-hour work day.
Should I replace all my windows at once?
If you want to get more efficient windows and save money on energy costs, replacing all of the windows at the same time is the only way to gain that benefit. On the other hand, if you have only one or two windows that are broken or leaky, you can replace just those.
