How Installing Energy-Efficient Windows in Trumbull Saves You Money
By upgrading to energy-efficient windows, you and your family can enjoy several benefits, including:
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Decrease your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 147 pounds per year on average.
- Save money on energy bills: Switching to energy-efficient windows reduces your energy bills by about 12% since you need less energy.
Estimated Cost of Window Replacement in Trumbull
Windows come in varying shapes and sizes, so costs and services will differ greatly. Here are the average costs and services that you'll find from window installers.
How Much Do New Windows Cost?
Generally, Trumbull homeowners can expect their window replacements to range from $250 to $1,200. The average cost is at about $600. But prices differ considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations and replacements, which will add extra costs to your project.
Keep in mind that energy-efficient windows may have a higher price, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.
Another factor that affects the overall cost is the material of the frame you choose. Aluminum frames are generally the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
The first step of a replacement is to figure out whether you should get a full-frame or pocket installation.
A full-frame installation replaces the full window, including the windowsill, frame, trim and the window panes. As this type of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.
Your window installation company should be able to help you figure out which type of installation you need.

How We Choose the Best Window Installers in Trumbull
The EcoWatch Reviews team differs from most reviewers, as we assess these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Trumbull and ranked them using the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve the Trumbull area so you can find a quality window installation company near you.
Work Quality
We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each installer 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 very important review factor is customer feedback. If most customers don't have nice things to say about their experience with a certain company, you won't see it featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, we gave 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 give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Trumbull's climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Trumbull window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Trumbull, CT Window Replacement FAQs
What is the typical cost to install new windows?
The average cost to replace a single window can range from $450 to $650. There are many factors that influence how much it costs, including the materials used in designing the windows, local labor costs, the number of windows, styles and sizes of windows, how energy-efficient the windows are and your property's location.
What kind of window is the most energy-efficient?
A window's energy efficiency is affected by several factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.
Do I really need to use a window installation company?
Unless you're handy and have the time needed to replace your own windows, we recommend hiring a professional installer. The window installation process is complicated and can take anywhere from four to six hours for a single window. Although it's tempting to try to save money by doing it yourself, hiring a professional is a faster, more efficient and much safer option.
How often should you replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to operate, they may be in need of replacement.
Should I replace all my windows at once?
If your windows are greater than 20 years old, it's most likely time to replace all of them. By that point, they are usually less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
