How Installing Energy-Efficient Windows in Norwalk Saves You Money
There are several perks of switching to energy-efficient windows. A few reasons you may want to consider making the change are the following:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its real estate value.
- Save money on energy bills: Since energy-efficient windows lower how much energy you need to heat or cool your home, they can help you save around $509 annually on your energy bills in Norwalk.
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Norwalk, that’s about 117 pounds per year on average.
Estimated Cost of Window Replacement in Norwalk
Windows come in various shapes, purposes and styles, so costs and services will vary remarkably depending on several factors. Below, we describe the typical cost and services that you can get from window installers.
How Much Do New Windows Cost?
Typically, Norwalk homeowners can anticipate their window installations to range from $250 to $1,200. The most common installations sit at approximately $600. This is due to the fact that window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as the location of your property.
With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — especially if you live in a hot climate — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Norwalk homeowners $509+ per year after replacing single-pane windows.
Something else that influences the total cost is the material you select for your frame. Aluminum frames are generally the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive, as 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?
Generally, there are two types of window replacement services you can get: full-frame and pocket installations.
Full-frame installations entail replacing the complete window, including the sill, trim and frame. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable rot. Because these installations are more involved, they will raise the total cost. A pocket installation involves replacing a window within the existing frame. So, instead of taking out the whole window and reinstalling it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you’re still debating which kind of installation you need, you can consult with your installer and get their advice. The decision mostly depends on how old the frames are and if there’s any damage present.

The EcoWatch Reviews team differs from other reviewers since we’re examining these companies through a sustainability lens. We’ve reviewed the top window replacement companies in Norwalk primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers that serve the Norwalk area so you can find the right window installation company near you.
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 included in our guide to ensure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
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 may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including cost, quality of parts, professionalism, warranty, quality of installation and more.
Cost
This one is a give-and-take: as with 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 range of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. That’s why window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) 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 installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Norwalk, CA Window Replacement FAQs
How much does a window install cost?
The national average cost of replacing a window is around $600 but can range between $200 and $1,200, depending on several 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, bear 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 different types of windows?
The most common types of windows for homes are double-hung and single-hung windows, bay windows, transom windows, casement windows, awning windows, slider windows and picture windows.
Do you really need to use a window installation company?
Unless you have home repair skills and have all the tools you need to replace your own windows, we recommend hiring the pros. The process of installing windows is quite involved and can take anywhere from four to six hours for one window. Although it’s tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and much safer alternative.
When is the best time of year to replace windows?
Replacement windows can be installed any time of the year, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into your home, so the temperature outside isn’t necessarily a big factor. Most importantly, the weather should be dry.
