How Installing Energy-Efficient Windows in Berkley Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to think about making the switch:
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Save on electricity bills: Switching to energy-efficient windows reduces your energy bills by about 12% because you use less energy.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Berkley, that's about 460 pounds per year on average.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Berkley
Each window installation company offers various services and has varying costs depending on a few factors.
How Much Do New Windows Cost?
Typically, Berkley homeowners can expect their replacement window installations to range from $250 to $1,200. The most common installations sit at approximately $600. But costs differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations, which carry a higher price tag.
It's important to remember that windows with higher efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Berkley homeowners $453+ a year when replacing single-pane windows.
Getting free quotes from several providers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first step of a replacement is to think about whether you need a full-frame or pocket installation.
A full-frame installation replaces the complete window, including the windowsill, frame, trim and the window panes. Because this type of installation is more involved, it will be more expensive than a pocket installation. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.
Your window installation company can help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Berkley
EcoWatch reviews differ from most reviews because we evaluate these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings using the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.
Work Quality
We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each installer featured on this list to ensure its technicians are well-qualified and that the company has gotten lots 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 customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including professionalism, quality of parts, cost, quality of installation, warranty and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. That's why window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Berkley's climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Berkley window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Berkley, CO Window Replacement FAQs
How much does window installation cost?
The national average cost of installing a single window is around $600 but can range between $200 and $1,200, based on a variety of factors. The price is often dependent on the type and material of the window, the size of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What kind of window is the most energy-efficient?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. If you want to be sure you'll get the most energy-efficient windows, look for models that have the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.
Do I really need to use a window installation company?
Unless you have experience with home improvement projects and have the time needed to replace your own windows, we recommend hiring the pros. The process of installing windows is quite involved 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 safer alternative.
How long does it usually take to install windows?
Because the average installation time is 30 minutes per window, about 16 windows can be installed in an 8-hour work day.
How often do you need to replace your windows?
Windows generally have a lifespan of about 20 to 30 years, but anytime you see damage on your windows, it's a good time to have them checked by an expert to determine if they need any repairs or replacements.
