Why you can trust EcoWatch
Although renewable energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your house's efficiency can also have a large impact on home energy conservation. The Department of Energy estimates that heat gained or lost through old or damaged windows could account for nearly 30% of residential energy climate usage. In Woodstock, where the energy bills are an average of $36 per month, that's almost $$129 per year wasted.
Replacement windows improve the insulation in your home, not only making you more comfortable during extreme temperatures, but also saving you money and helping the environment.
As windows are so important for your home, choosing the best company for you is a big decision to make. That's why the EcoWatch team has curated this list of the best window replacement companies, so you can make an informed decision more easily.

How Installing Energy-Efficient Windows in Woodstock Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to think about making the switch:
- Protect your investment: If you have an older home, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
- Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Replacing your windows with energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
- Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Woodstock, that's about 147 pounds per year on average.
Estimated Cost of Window Replacement in Woodstock
Let's take a look at the cost of replacing your windows and the types of services offered by installers.
How Much Do New Windows Cost?
Typically, homeowners in Woodstock can anticipate that most window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. How much it will cost you varies depending on several factors, including size, number of windows, type, material, the location of your home and more.
It's also worth noting that energy-efficient windows will typically cost more initially, but Energy Star estimates that upgrading the windows on your Woodstock 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. The amount of money you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Getting free quotes from multiple installers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first step when considering a replacement is to think about whether you want a full-frame or pocket installation.
Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has significant rot or deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations are on the simpler end and won't carry as large a bill because they involve merely replacing the window within its existing frame. But if the frame has any damage, you may have to get a full-frame installation instead.
If you're still trying to decide which type of installation to get, you can talk to your installer and get their advice. The choice mostly is influenced by the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in Woodstock
EcoWatch differs from most reviewers since we look at these companies through a sustainability lens. We have decided to assess the best window installers in Woodstock mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
When installing new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the type of window you get. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don't have positive feedback about their experience with a certain window installation company, you won't see it 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 points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a sizable investment, so you'll want to make sure that investment is well protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Woodstock's climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Woodstock window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Woodstock, CT Window Replacement FAQs
What is the typical cost to install new windows in a home?
The typical cost of installing a window ranges from $450 to $650. There are a variety of factors that affect how much it costs, including the materials used in designing the windows, your property's location, how energy-efficient the windows are, styles and sizes of windows, local labor costs and the number of windows.
What are the different kinds of windows?
The most common types of windows for homes are slider windows, awning windows, double-hung and single-hung windows, transom windows, bay windows, picture windows and casement windows.
Can you replace your own windows?
Even though it is possible to install your own windows, doing so is time-consuming and requires a lot of handiness. Hiring a professional can help ensure that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.
What time of year should I replace my windows?
Replacement windows can be installed during any season, but autumn might be best. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into the home, so the temperature outside doesn't necessarily matter that much. Most importantly, the weather should be dry.
Should I replace my windows all at once?
If you're upgrading your windows because of energy-efficiency, replacing all of the windows at once is the only way to see a noticeable difference. However, if you have just one or two windows that are damaged or leaky, you can replace just those.
