How Installing Energy-Efficient Windows in Wethersfield Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more ways switching out your windows could benefit you:
- Decrease your carbon footprint: By using less energy after you switch to Energy Star certified windows, you’ll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
- Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of household energy use. Upgrading to energy-efficient windows can help reduce that amount, which helps you save more on your bills.
Estimated Cost of Window Replacement in Wethersfield
Each window installation company offers varying services and has varying prices based on several factors.
How Much Do New Windows Cost?
Generally, Wethersfield homeowners can expect their window replacements to range from $250 to $1,200. The average cost is at around $600. This is because of the fact that the cost of window installations depend on several factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.
Whether or not you want energy-efficient windows is another factor that will affect the cost. These will usually cost more than other windows, but on the other hand, you can save about $446 a year on your energy bills in Wethersfield.
Something else that influences the overall cost is the material you pick for your frame. Aluminum frames are typically the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
There are typically two kinds of window installation services: full-frame and pocket installations.
Full-frame installations involve replacing the full window, including the trim, sill and frame. You most likely need a full-frame installation when you want a new style or your window has considerable damage or rot. These installations are more involved and will raise overall costs. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are simpler and will be less expensive, but you can’t do this type of installment if you have any pre-existing rot or water damage.
Your window replacement company will be able to help you choose what’s best for your needs. In Wethersfield, the decision will mostly depend on how old your windows are and if there’s any damage. Wood can decay if not properly maintained over the years, so it’s a good idea to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Wethersfield
In our hunt to find the most reliable, eco-friendly window installers in Wethersfield, EcoWatch assessed dozens of companies before deciding on these. We have assessed the best window installation companies in Wethersfield mainly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for Wethersfield, we paid more attention to companies that provide services to the city. There are certainly reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Wethersfield.
Work Quality
We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each company on this list 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
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have positive feedback about their service from a certain window installation company, you won’t see it featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window installation companies won’t always provide the most 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
As discussed previously, windows are a considerable investment, so you’ll want to be certain that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
