Why you can trust EcoWatch
Although environmentally friendly energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your house's energy efficiency can also have a big impact on home energy conservation. Potential leaks or drafts can reduce your home's energy efficiency by up to 30%, according to the Department of Energy. In Berlin, that's about $205 a year that you could save on your electricity bills after making the switch.
That's not great for your wallet or the environment, but one of the best window installation companies can help with that.
Efficient windows are of particular importance in Berlin, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $205 each year.

How Installing Energy-Efficient Windows in Berlin Saves You Money
Energy-efficient windows can offer benefits in more than one way. Here are some reasons you may want to make the switch:
- More efficient energy use in your household: Because the winters can get very cold in Berlin, homeowners usually depend on their heater a lot. Energy-efficient windows lower how much heat is lost through your windows, making it easier to keep your house warm.
- Save on power bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
Estimated Cost of Window Replacement in Berlin
Each window installer provides varying services and has varying prices based on several factors.
How Much Do New Windows Cost?
According to our research, the average cost to replace a single window is about $600. However, window installation costs can range from $200 to $1,200 a window. These numbers vary depending on the specifics of your installation, such as type, number of windows, size, material, the location of your home and more.
With windows, efficiency is the most important factor for many homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Berlin homeowners $205+ each year after replacing single-pane windows.
Something else that affects the total cost is the material you choose for your frame. Aluminum frames are typically the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive, 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?
There are generally two types of window installation services: full-frame and pocket installations.
A full-frame installation replaces the complete window, such as the sill, frame, trim and the window panes. As this type of installation requires more time and labor, it will be more expensive than a pocket installation. A pocket installation means replacing a window within the existing frame, which is generally less expensive than a full-frame installation.
Your window installer should be able to help you decide which type of installation you need.

How We Choose the Best Window Installers in Berlin
EcoWatch reviews are different from most reviews because we evaluate these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Berlin and ranked them based on the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve Berlin so you can find the right 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 featured in our guide to ensure its technicians are well-qualified and that the company has received tons 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 positive things to say about their experience with 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 installation companies won't always provide the most quality service. Still, we want to make sure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that give you 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 low efficiency, water damage 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, MD Window Replacement FAQs
How much does a window install cost?
The typical cost to install one window ranges between $450 and $650. There are several factors that influence how much it costs, which include styles and sizes of windows, the number of windows, your property's location, the materials used in designing the windows, local labor costs and how energy-efficient the windows are.
What kind of window is the best for energy efficiency?
A window's energy efficiency is influenced by a number of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.
When should I use a window installation company?
You should use a window installation company whenever you want to upgrade your windows. Installing windows is a complicated process that can take a lot of time, so it's best handled by the professionals.
Should I replace my windows all at the same time?
If your windows are more than 20 years old, it's probably time to replace all of them. At that point, they are often less efficient, draftier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less stress.
