How Installing Energy-Efficient Windows in Hamden Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here's more information on how upgrading your windows could help you:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Save money on power bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of household energy use. Switching to energy-efficient windows can help lower that amount, which helps you save some money on your bills.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help increase the value of your property if you decide to sell.
- Reduce your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 147 pounds.
Estimated Cost of Window Replacement in Hamden
Windows come in varying shapes and sizes, so costs and services will vary considerably. Here are the average costs and the primary services that you can find from the average window installation company.
How Much Do New Windows Cost?
Typically, Hamden homeowners can expect their window installations to range from $250 to $1,200. The most common installations sit at about $600. These figures vary based on specific characteristics of your installation, such as size, material, the location of your home, type, number of windows and more.
It's also worth noting that energy-efficient windows will cost more initially, but Energy Star estimates that switching out the windows on your Hamden home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Asking for free quotes from several companies is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first thing to ask yourself when planning a window installation is: Do you want a full-frame installation or a pocket installation?
A full-frame installation replaces the full window, such as the windowsill, frame, trim and the window panes. Because this type of installation is more involved, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won't cost as much, but you can't do this type of installment if you have any pre-existing rot or water damage.
Your window installer can help you choose which type of installation you should get.

How We Choose the Best Window Installers in Hamden
EcoWatch reviews are different from other reviews, as we assess these companies through a sustainability lens. We have decided to evaluate the best window replacement companies in Hamden mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for Hamden, we only included companies that cover the city. There are certainly reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Hamden.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each company featured in our guide to ensure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If most customers don't have good feedback about their service from a certain window installation company, it won't be featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. That's why window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Hamden, CT Window Replacement FAQs
What is the average cost to install new windows in a home?
The national average cost to install one window is around $600 but can range from $200 to $1,200, depending on a few different factors. The price is generally influenced by the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the different types of windows?
There are several different types of windows you can get for your house, such as double-hung and single-hung windows, picture windows, awning windows, casement windows, slider windows, transom windows and bay windows.
Do I really need to use a window installation company?
Unless you're handy and have the time needed to replace your own windows, we recommend hiring a professional. 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 company is a faster, more efficient and safer alternative.
How long does window installation take?
Each window takes about 30 minutes to install based on the type of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
What time of year is the best time to replace my windows?
Although you can install windows any time of year, warmer weather is often better for replacing windows. In addition, it shouldn't be raining, because rain can make the installation harder.
