Why you can trust EcoWatch
Whether you're updating for aesthetics or have damaged windows, windows play a key role in conserving your home's energy. The Department of Energy estimates that heat gained or lost through old or damaged windows could represent about 30% of residential energy climate use. In Norwich, where the electric bills are an average of $40 per month, that's almost $$142 per year wasted.
Installing efficient windows on your house can help you save money every month on your power bills — and you can help the environment, too.
Efficient windows are particularly important in Norwich, where the temperature varies throughout the year. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $424 each year.

How Installing Energy-Efficient Windows in Norwich Saves You Money
Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to take the plunge and make the switch:
- Save money on energy bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
- Better temperature control in your home: When you live in a place like Norwich where the winters can be very cold, you often have to depend on your heater to keep your home warm. Energy-efficient windows can cut back on how hard your heater needs to work to heat 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.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Norwich
When researching window installation, each company offers varying services and prices. Let's look at some typical costs and services.
How Much Do New Windows Cost?
Generally, homeowners in Norwich can anticipate that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. Costs will vary significantly based on the quality of your products, the number of windows you need, your location and the current condition of your home. Many window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. Additional services will increase your overall project costs.
It's also worth bearing in mind that energy-efficient windows will almost always cost more initially, but Energy Star predicts that switching out the windows on your Norwich home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you'll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Something else that influences the overall cost is the material of the frame you pick. Aluminum frames are generally the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
The first step of a window installation is to clarify whether you need a full-frame or pocket installation.
Full-frame installations are usually recommended when you want to change the style of your windows or your window has significant rot. With this service, your professionals will replace the total window, including the sill, trim and frame. Pocket installations are simpler and won't carry as large a bill, as they entail merely replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.
Your window installer can help you choose which type of installation you need.

How We Choose the Best Window Installers in Norwich
In our search to make your home improvements easier and more eco-friendly in Norwich, the EcoWatch Reviews team chose the above companies as the best window installation companies in the city. We've evaluated the best window installation companies in Norwich mainly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each installer on this list to ensure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the most customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including quality of installation, warranty, quality of parts, professionalism, cost and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a sizable investment, so you'll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
