How Installing Energy-Efficient Windows in Berlin Saves You Money

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here are more ways upgrading your windows could help you:

  • Protect your investment: If you have an older home, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.
  • Save on power bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of energy use in your home. Switching to energy-efficient windows can help reduce that amount, which helps you save some money on your bills.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Reduce your carbon footprint: By using less energy after switching to energy-efficient windows, you’ll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Berlin

When looking into window installation, each company offers different services and prices. Let’s take a look at some average costs and services.

How Much Do New Windows Cost?

On average, Berlin homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at approximately $600. These figures vary depending on the specifics of your installation, such as number of windows, size, type, the location of your home, material and more.

It’s also worth keeping in mind that energy-efficient windows will almost always cost more initially, but Energy Star estimates that upgrading the windows on your Berlin home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

We advise getting free quotes from several window companies to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

There are generally two types of window replacement services: full-frame and pocket installations.

A full-frame installation replaces the entire window, such as the windowsill, frame, trim and the window panes. Because this kind of installation requires more time, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won’t cost as much, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

Your window installation company will be able to advise you on the best type for your project. In Berlin, the decision will mostly be influenced by the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Berlin

In our search to find the most reliable, eco-friendly window installers in Berlin, EcoWatch examined dozens of companies before settling on these. Along with energy efficiency, we reviewed several window installers in Berlin and ranked them using 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

When picking new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the type of window you get. 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 good feedback about their service from a certain company, it won’t be 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 previously, windows are a substantial investment, so you’ll want to be certain that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of 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, CT Window Replacement FAQs

How much does a window install cost?

The average cost to replace a window can range between $450 and $650. There are several factors that affect how much it costs, including your property’s location, local labor costs, how energy-efficient the windows are, styles and sizes of windows, the materials used in designing the windows and the number of windows.

What are the most common kinds of replacement windows?

The most common kinds of windows for homes include: casement windows, double-hung and single-hung windows, bay windows, transom windows, slider windows, awning windows and picture windows.

What services do window installation companies do?

Window installation companies will do the entire process — from replacing your old windows with brand-new ones to cleaning up after the installation. Additionally, many companies offer window manufacturing, customization and repairs.

What time of year is the best time to replace my windows?

Replacement windows can be installed at any time, but autumn might be the best season. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into your home, so the temperature outside isn’t necessarily a big factor. What’s most important is that the weather should be dry.

Should I replace my windows all at the same time?

If your windows are greater than 20 years old, you probably need to replace all of them. By that point, they are typically less efficient, leakier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less stress.
