How Installing Energy-Efficient Windows in Berlin Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here are more ways upgrading your windows could help you:
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Installing energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
- 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 increase the value of your home if you decide to sell.
- 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.
- Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Berlin
Windows come in varying shapes and sizes, so costs and services will differ greatly. Here are the typical costs and the primary services that you can find from the average window installation company.
How Much Do New Windows Cost?
Generally, homeowners in Berlin can anticipate that most replacement window installations will cost between $250 and $1,200, with the average cost at around $600. How much it will cost varies based on several factors, including material, number of windows, type, size, the location of your home and more.
It's important to bear in mind that windows with the best 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 Berlin homeowners $446+ a year when replacing single-pane windows.
Asking for free quotes from several companies is the best way to figure out which one is right for you.
What Services do Window Installers Offer?
When it comes to window installations, there are generally two types that your installer will offer: full-frame and pocket installations.
Full-frame installations require replacing the full window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has a great amount of rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations are simpler and won't cost as much because they entail merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.
If you're hiring a reputable window installation company, your company can recommend the best type for your project. In Berlin, the decision will mostly be based on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Berlin
In our hunt to find the most reliable, eco-friendly window installers in Berlin, EcoWatch assessed dozens of companies before settling on these. We have decided to review the best window installation companies in Berlin mainly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve Berlin so you can find the right window installation company near you.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each company in our guide 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
Customer feedback is another very important review factor. If most customers don't have nice feedback about their service from a certain window installation company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window installation companies may not provide the most quality service. On the other hand, we want to make sure we're highlighting companies that provide a variety of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. That's why window installation companies that offer 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 earn higher rankings by our standards. We like to see at least ten years of experience.
Berlin, CT Window Replacement FAQs
How much should window installation cost?
The typical cost of replacing one window can range between $450 and $650. There are many factors that influence the price, which include how energy-efficient the windows are, your property's location, the materials used in designing the windows, local labor costs, styles and sizes of windows and the number of windows.
What are the different types of windows?
There are several different kinds of windows you can get for your house, such as slider windows, transom windows, awning windows, double-hung and single-hung windows, picture windows, bay windows and casement windows.
When do I need to use a window installation company?
Unless you're handy and have the tools needed to replace your own windows, we recommend hiring a professional. The process of installing windows is complex and can take anywhere from four to six hours for a single window. Although it's tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and much safer option.
How long does window installation usually take?
Since the average installation time of a window is 30 minutes, about 16 windows can be installed in a typical 8-hour work day.
Should I replace my windows all at once?
If your windows are more than 20 years old, it's probably time to replace all of them. By that point, they are often less efficient, draftier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.
