How Installing Energy-Efficient Windows in Norwalk Saves You Money
By upgrading to energy-efficient windows, you and your family can enjoy several benefits, including:
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
- Reduce your carbon footprint: In Norwalk, you can cut your indirect greenhouse gas emissions by about 147 pounds per year after you switch to energy-efficient windows.
- Save on energy bills: After you install energy-efficient windows, you can expect a reduction in your bills by about 12% because you'll need less energy to heat or cool your home.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
Estimated Cost of Window Replacement in Norwalk
Each window replacement company provides varying services and has varying costs based on a few factors.
How Much Do New Windows Cost?
According to our market research, the average cost of installing a single window is around $600. However, window installation costs can range from $200 to $1,200 for each window. How much it will cost you depends on several factors, including the location of your home, type, size, number of windows, material and more.
With windows, efficiency is one of the most important factors for most homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Norwalk homeowners $441+ per year after replacing single-pane windows.
How much your window installation costs will also vary depending on the type of window material you choose for the frames. Wood windows are usually the most expensive, though it depends if they are 100% 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 question to ask yourself when considering a window replacement is: Do you want a full-frame installation or a pocket installation?
Full-frame installations are necessary when you want to change the style of your windows or your window has a lot of rot or deterioration. With this service, your installers will replace the complete window, including the sill, trim and frame. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and won't cost as much, but you can't do this type of installment if you have any pre-existing rot or water damage.
If you're unsure which kind of window installation service you should get, your installer can advise you. Typically, the decision depends on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Norwalk
The EcoWatch Reviews team is different from most reviewers, as we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and ranked them based on the following methodology:
Service Area
Since this is a guide for Norwalk, we gave more points to companies that serve the city. There are certainly other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Norwalk.
Work Quality
When selecting new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand you opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including warranty, quality of installation, professionalism, quality of parts, cost and more.
Cost
Cheaper windows certainly don't 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 make sure that investment is protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Norwalk's climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Norwalk window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Norwalk, CT Window Replacement FAQs
What is the typical cost to replace windows?
The typical cost of installing one window can range between $450 and $650. There are a variety of factors that affect how much it costs, including how energy-efficient the windows are, local labor costs, the number of windows, your property's location, styles and sizes of windows and the materials used in designing the windows.
Which type of window should I get?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. To be sure you'll get the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.
Can I install my own windows?
If you're handy and know how to replace a window, it's possible to install your own windows. However, if you don't have the time or know-how, we recommend hiring a professional.
How long does it usually take to install windows?
Since the average installation time of a window is 30 minutes, around 16 windows can be installed in a typical 8-hour work day.
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. No matter when you install them, the contractors will take steps to make sure 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.
