How Installing Energy-Efficient Windows in Berlin Saves You Money
By switching to energy-efficient windows, you can benefit in several ways, such as:
- Protect your investment: If you have an older home, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help raise the value of your property if you decide to sell.
- Save on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of household energy use. Switching to energy-efficient windows can help decrease that amount, which helps you save some money on your bills.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Reduce your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 147 pounds.
Estimated Cost of Window Replacement in Berlin
When looking into window installation, each company offers different services and costs. Let’s go over some average costs and services.
How Much Do New Windows Cost?
The national average cost to install a single window is about $600 but can range anywhere from $200 to $1,200. But costs will differ significantly depending on the quality of your products, the number of windows you need, your location and the current condition of your home. Many window companies also offer replacement door installations and other add-ons like coating, baths, shutters and more. These extra services will increase your overall project costs.
It’s important to remember that windows with the best efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Berlin homeowners $446+ a year when replacing single-pane windows.
Something else that influences the overall cost is the material of the frame you select. 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 and cost somewhere between the other two.
What Services do Window Installers Offer?
The first step of a window installation is to figure out whether you should get a full-frame or pocket installation.
A full-frame installation replaces the entire window, such as the sill, frame, trim and the window panes. As this kind of installation requires more time, it will cost more than a pocket installation. A pocket installation entails installing a new window within the old frame. This means instead of taking out the whole unit and reinstalling it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company should be able to help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Berlin
EcoWatch reviews differ from other reviews because we’re examining these companies through a sustainability lens. We’ve evaluated the best window installation companies in Berlin primarily based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows have been shown to lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Because this is a guide for Berlin, we only included companies that provide services to the city. There are certainly reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Berlin.
Work Quality
When installing new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the type of window you opt for. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don’t have nice things to say about their service from a certain window installation 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 points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Berlin’s climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Berlin window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Berlin, CT Window Replacement FAQs
How much should a window install cost?
The national average cost of installing one window is around $600 but can range from $200 to $1,200, based on a variety of factors. The price is usually influenced by the size of the window, the type and material of the window and the location of your property. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What are the different types of windows?
The most common types of windows for homes include: bay windows, double-hung and single-hung windows, casement windows, slider windows, awning windows, picture windows and transom windows.
What do window installers do?
Window installation professionals visit your property to remove your old windows and replace them with new ones. Some providers install products sold by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is finished.
What time of year is a good time to replace my windows?
Although you can install windows any time of year, warmer weather is generally better for replacing windows. Additionally, it shouldn’t be raining, since rain can make the installation more difficult.
Should I replace my windows all at once?
If you’re upgrading your windows because of energy-efficiency, replacing all your windows at the same time is the only way to gain that benefit. On the other hand, if you have only a few windows that are broken or leaky, you can replace just those.
