How Installing Energy-Efficient Windows in Trumbull Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here's more information on how upgrading your windows could benefit you:
- Save money on power bills: Since energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save around $441 annually on your energy bills in Trumbull.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
- Better temperature control in your home: Residing in a very cold place like Trumbull can often mean needing your heater to keep your house cool. Energy-efficient windows can cut back on how hard your heating system needs to work to heat your home.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
Estimated Cost of Window Replacement in Trumbull
Windows come in different shapes and sizes, so costs and services will vary remarkably. Here are the average costs and services that you can find from window installation companies.
How Much Do New Windows Cost?
Typically, Trumbull homeowners can expect their window installations to range from $250 to $1,200. The most common installations sit at around $600. Costs will vary considerably based on the quality of your products, your location, the number of windows you need and the current condition of your home. A lot of window companies also offer door installations and other add-ons like baths, coating, shutters and more. Additional services will increase your overall project costs.
It's important to note that windows with higher efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Trumbull homeowners $441+ a year when replacing single-pane windows.
We advise getting free quotes from multiple window installation companies to find the one that works best for your budget.
What Services do Window Installers Offer?
There are typically two kinds of window installation services: full-frame and pocket installations.
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 installers will replace the full window, including the frame, trim and sill. A pocket installation entails replacing a window within the existing frame, which is generally less expensive than a full-frame installation.
If you're unsure which kind of window installation service you need, your installer can assist you. In general, the choice is based 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 Trumbull
EcoWatch reviews differ from most reviews since we assess these companies through a sustainability lens. We have reviewed the top window installation companies in Trumbull mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to cut your electricity 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 Trumbull so you can find a quality window installation company near you.
Work Quality
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer included in our guide to make sure its technicians are well-qualified and that the company has received lots 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 installer, it won't be featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers' prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a substantial investment, so you'll want to make sure 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 a while. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
