How Installing Energy-Efficient Windows in Hillsborough Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here are more ways upgrading your windows could benefit you:
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Switching to energy-efficient models can help reduce that amount, therefore saving you about 12% more on your bills.
- Better temperature control in your home: When you live in a place like Hillsborough where the winters can get very cold, you usually need to depend on your heater to keep your home warm. Energy-efficient windows can decrease the amount of heat lost through your windows when heating your home.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if you have an older home.
Estimated Cost of Window Replacement in Hillsborough
Windows come in various styles, shapes and purposes, so costs and services will vary considerably depending on several factors. Below, we detail the average cost and services that you can get from window installers.
How Much Do New Windows Cost?
According to our research, the typical cost to replace a single window is around $600. However, window installation costs can range from $200 to $1,200 a window. These amounts vary based on specific characteristics of your installation, including the location of your home, type, size, number of windows, material and more.
With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Hillsborough homeowners $440+ each year after replacing single-pane windows.
We recommend requesting free quotes from several window installers to find the one that works best for your budget.
What Services do Window Installers Offer?
When it comes to window installations, in general there are two kinds that your installer will have: full-frame and pocket installations.
A full-frame installation replaces the entire window, including the windowsill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are on the simpler end 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.
If you're not sure which kind of window installation service you should get, your installer should be able to assist you. Generally, the decision is based 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 Hillsborough
The EcoWatch Reviews team is different from most reviewers since we're examining these companies through a sustainability lens. We've evaluated the best window replacement companies in Hillsborough mainly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find the best 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 insulation and performance as the type of window you opt for. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the most customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including quality of installation, quality of parts, cost, professionalism, warranty 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 providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a proven track record in the industry. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
