How Installing Energy-Efficient Windows in Bristol Saves You Money
By upgrading to energy-efficient windows, you can take advantage of several benefits, including:
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Save money on electricity bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of energy use in your home. Installing energy-efficient windows can help reduce that number, which helps you save more on your bills.
- Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 147 pounds per year on average.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
Estimated Cost of Window Replacement in Bristol
Each window installation company offers varying services and has different price points based on several factors.
How Much Do New Windows Cost?
Generally, homeowners in Bristol can expect that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. But costs vary considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations, which will add extra costs to your project.
It’s important to bear in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Bristol homeowners $446+ a year when replacing single-pane windows.
Costs will also vary based on the material you pick for your window frames. Aluminum frames are the least expensive. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer 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?
The first thing to ask yourself when considering a window replacement is: Should you get a full-frame installation or a pocket installation?
Full-frame installations involve replacing the total window, including the trim, frame and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has considerable deterioration. These installations are more involved and will increase overall costs. A pocket installation means replacing a window without taking out the complete frame, which tends to be cheaper than a full-frame installation.
If you’re still trying to decide which type of installation you should get, you can consult with your installer and get their recommendation. The decision mostly is influenced by the age of your window frames and if there’s any damage present.

How We Choose the Best Window Installers in Bristol
In our hunt to find the most reliable, eco-friendly window installers in Bristol, the EcoWatch Reviews team assessed many companies before settling on these. Along with energy efficiency, we analyzed several window installers in Bristol and assigned rankings using the following methodology:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers 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 included on this list to ensure its contractors are well-qualified and that the company has received 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 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 installers are not going to provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that provide a spectrum of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed, windows are a significant 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
Because of Bristol’s climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Bristol window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Bristol, CT Window Replacement FAQs
How much does a window install cost?
The typical cost to install a single window ranges from $450 to $650. There are many factors that affect how much it costs, such as local labor costs, styles and sizes of windows, your property’s location, the number of windows, the materials used in designing the windows and how energy-efficient the windows are.
What are the different types of windows?
The most common kinds of windows for homes are awning windows, transom windows, picture windows, casement windows, slider windows, double-hung and single-hung windows and bay windows.
Can I replace my own windows?
If you’re handy and know how to replace a window, it’s possible to install your own windows. But if you don’t have the time or skills, we recommend getting a professional to do it for you.
What time of year is the best time to replace my windows?
Replacement windows can be installed any time of the year, but autumn might be the best season. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into your house, so the temperature outside isn’t necessarily a big factor. Most importantly, the weather should be dry.
How often should you replace your windows?
Windows generally last about 20 to 30 years, but anytime you notice damage on your windows, it’s a good time to have an expert take a look at them to determine if they are in need of a repair or replacement.
