How Installing Energy-Efficient Windows in Berlin Saves You Money

There are quite a few benefits of switching to energy-efficient windows. A few reasons you may want to consider making the switch are the following:

  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, especially if your home is on the older side.
  • Save money on power bills: Since energy-efficient windows reduce the amount of energy needed to heat or cool your home, the switch can help you save about $599 annually on your energy bills in Berlin.

Estimated Cost of Window Replacement in Berlin

When looking into window installation, each company provides varying services and costs. Let's take a look at some typical costs and services.

How Much Do New Windows Cost?

The average cost to install one window is about $600 but can range anywhere from $200 to $1,200. These figures vary based on the specifics of your installation, including number of windows, material, the location of your home, size, type and more.

It's also worth noting that energy-efficient windows will usually cost more initially, but Energy Star predicts that upgrading the windows on your Berlin home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you'll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Something else that affects the overall cost is the material of the frame you select. Aluminum frames are usually the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

Generally, there are two types of window replacement services companies offer: full-frame and pocket installations.

A full-frame installation replaces the full window, including the sill, frame, trim and the window panes. Because this type of installation requires more time, it will cost more than a pocket installation. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

If you're not sure which window installation service you should get, your installer can assist you. Typically, the decision depends on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Berlin

EcoWatch reviews are different from other reviews because we examine these companies through a sustainability lens. We've assessed the best window replacement companies in Berlin primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is 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 willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each company in our guide to make sure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews to find the companies with the most consistent customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including warranty, quality of parts, professionalism, cost, quality of installation and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing the prices of providers, we awarded higher points 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 make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Berlin, NH Window Replacement FAQs

How much should a window install cost?

The average cost of installing a single window ranges between $450 and $650. There are a variety of factors that influence how much it costs, such as how energy-efficient the windows are, the materials used in designing the windows, the number of windows, your property's location, styles and sizes of windows and local labor costs.

What kind of window is the best for energy efficiency?

Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — this means they're certified energy-efficient by the U.S. Department of Energy.

What do window installation companies do?

Window installers go to your home to remove your old windows and replace them with new ones. Some companies install products made by other companies, whereas others install their own windows. The installer will also clean up after the installation is finished.

How often should you replace windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have any damage on them, or they have become difficult to operate, they may be in need of replacement.

Should I replace my windows all at once?

If your windows are more than 20 years old, you most likely need to replace all of them. By that point, they are often less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.
