How Installing Energy-Efficient Windows in Stafford Saves You Money
There are quite a few benefits of switching to energy-efficient windows. Some reasons you may want to consider making the change are the following:
- Protect your investment: When you have an older home, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its value.
- Better temperature control in your home: When you live in a city like Stafford where the winters can be very cold, you often need to rely 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 reduce damage from the sun's UV rays to your floors, carpets and furniture.
- Save money on energy bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of household energy use. Upgrading to energy-efficient windows can help decrease that number, which helps you save $461 a year on your bills.
Estimated Cost of Window Replacement in Stafford
When researching window installation, each company provides varying services and costs. Let's look at some typical costs and services.
How Much Do New Windows Cost?
Generally, Stafford homeowners can expect their window installations to range from $250 to $1,200. The most common installations sit at about $600. Costs will differ significantly based on the current condition of your home, the quality of your products, your location and the number of windows you need. A lot of window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. Additional services will increase overall project costs.
Whether or not you opt for energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $461 a year on your energy bills in Stafford.
Costs will also vary depending on the material of your frame. Aluminum frames cost the least. They're sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
Generally, there are two types of window installation services you can get: full-frame and pocket installations.
A full-frame installation replaces the total window, such as the sill, frame, trim and the window panes. As this type of installation requires more time and labor, it will be more expensive than a pocket installation. A pocket installation means replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.
If you're unsure which window installation service you need, your installer can advise you. Typically, the decision is influenced by 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 Stafford
EcoWatch reviews are different from most reviews because we assess these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and assigned rankings using the following methodology:
Service Area
Since this is a guide for Stafford, we gave more points to companies that cover the city. There are certainly reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Stafford.
Work Quality
We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each company featured on this list to ensure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don't have good things to say about their service from a certain window installation company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window companies may not provide the highest quality service. Still, we want to ensure we're highlighting companies that offer a wide range 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 have 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 experience earn higher rankings by our standards. We like to see at least ten years of experience.
Stafford, CT Window Replacement FAQs
How much does a window install cost?
The average cost to replace a window ranges between $450 and $650. There are many factors that affect the cost, which include the number of windows, your property's location, local labor costs, styles and sizes of windows, how energy-efficient the windows are and the materials used in designing the windows.
What kind 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. 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 replace my own windows?
Even though you can install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Hiring a professional can help guarantee that the job is done properly and that you won't have to spend the time and effort to do it yourself.
How long does window installation take?
Each window takes around 30 minutes to install depending on the type of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that need to be installed.
