How Installing Energy-Efficient Windows in Branford Saves You Money
Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to make the switch:
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Save on power bills: Installing energy-efficient windows lowers your energy bills by about 12% since you need less energy.
- Decrease your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by about 147 pounds.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if your home is on the older side.
Estimated Cost of Window Replacement in Branford
Let’s take a look at the cost of installing new windows and the types of services you may need for your home.
How Much Do New Windows Cost?
On average, homeowners in Branford can expect that most window installations will range from $250 to $1,200, with the most common installations sitting at around $600. These numbers vary depending on the specifics of your installation, including the location of your home, number of windows, size, type, material and more.
It’s important to note that windows with higher efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Branford homeowners $420+ a year when replacing single-pane windows.
We recommend requesting free quotes from multiple window companies to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
There are typically two types of window replacement services: full-frame and pocket installations.
Full-frame installations involve replacing the full window, including the sill, trim and frame. Full-frame installations are necessary when you want to change the style of your windows or your window has significant damage or rot. These installations are more involved and will raise overall costs. 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 carry as large a bill, but you can’t do this kind of installment if you have any pre-existing rot or water damage.
If you’re unsure which window installation service you need, your installer should be able to advise you. Generally, the choice 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 Branford
In our search to make your home improvements easier and more eco-friendly in Branford, EcoWatch landed on the above companies as the best window installation companies in the city. We have evaluated the best window replacement companies in Branford primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Because this is a guide for Branford, we only included companies that serve the city. There are certainly reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Branford.
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 on this list to make sure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If most customers don’t have nice things to say about their service from a certain installer, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window companies are not going to provide the highest quality service. On the other hand, we want to make sure we’re highlighting companies that provide a range of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a hefty investment, so you’ll want to be certain that investment is protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Branford’s climate, homeowners will want to mitigate low efficiency, water damage and rot. We factored in local experience to reflect the ability of Branford window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Branford, CT Window Replacement FAQs
What is the average cost to install windows?
The average cost of installing a window ranges between $450 and $650. There are many factors that influence how much it costs, such as your property’s location, the number of windows, local labor costs, how energy-efficient the windows are, styles and sizes of windows and the materials used in designing the windows.
What are the types of windows?
The most common kinds of windows for homes include: double-hung and single-hung windows, transom windows, casement windows, awning windows, bay windows, slider windows and picture windows.
Can you replace your own windows?
If you’re handy and know how to replace a window, you may be able to install your own windows. However, if you don’t have the time or know-how, we recommend hiring a professional.
What time of year should I 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 doesn’t necessarily matter that much. What’s most important is that the weather should be dry.
How often do you need to replace your windows?
Windows usually have a lifespan of around 20 to 30 years, but anytime you notice damage on your windows, it’s a good idea to have them looked at by an expert to see if they need any repairs or replacements.
