Why you can trust EcoWatch
Although eco-friendly 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 considerable impact on home energy conservation. The Department of Energy estimates that heat or cool air lost through traditional or outdated windows could account for close to 30% of heating and cooling use. In Ledyard, where the power bills are an average of $36 per month, that's almost $$130 per year wasted.
Replacement windows improve your home's insulation, not only making you and your family more comfortable during extreme temperatures, but also saving you money and helping the environment.
As windows are so important for your home, picking the right company for you is a big decision to make. That's why the EcoWatch team has created this list of the top window installation companies, so you can make an informed decision more easily.

How Installing Energy-Efficient Windows in Ledyard Saves You Money
By switching to energy-efficient windows, you and your family can benefit in several ways, such as:
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Ledyard, that's about 147 pounds per year on average.
- 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 damaging UV rays.
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Switching to energy-efficient models can help lower that number, therefore saving you about 12% more on your bills.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Ledyard
Each window installation company provides varying services and has different price points based on several factors.
How Much Do New Windows Cost?
Generally, Ledyard homeowners can anticipate their window installations to range from $250 to $1,200. The average cost sits at approximately $600. This is because the cost of window installations depend on several factors specific to your home, such as the size, material and number of windows you need to install, as well as the location of your property.
With windows, efficiency is one of the most important factors for most homeowners. High efficiency windows may cost more initially, but by increasing the efficiency of your home — especially during the summer and winter — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Ledyard homeowners $424+ each year after replacing single-pane windows.
The cost of your window installation will also vary based on the kind of material you choose for the frames. Wood windows are usually the most expensive, although it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
The first thing to ask yourself when considering a window replacement is: Do you need a full-frame installation or a pocket installation?
Full-frame installations entail replacing the total 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 considerable rot. Full-frame installations are more involved and will raise overall costs. A pocket installation involves replacing a window without replacing the frame. This means instead of removing the whole window and reinstalling it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.
If you're hiring a reputable window installation company, your company will be able to recommend the best type for your project. In Ledyard, the choice will mostly be influenced by the efficiency of your home and the age of your existing frames.

How We Choose the Best Window Installers in Ledyard
The EcoWatch Reviews team differs from most reviewers, as we evaluate these companies through a sustainability lens. We have evaluated the best window installation companies in Ledyard mostly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve the Ledyard area so you can find the best window installation company near you.
Work Quality
When selecting new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand of window you opt for. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don't have nice feedback about their experience with a certain company, you won't see it featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try 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 provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Ledyard's climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Ledyard window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Ledyard, CT Window Replacement FAQs
How much does a window install cost?
The national average cost of replacing a window is about $600 but can range from $200 to $1,200, depending on several factors. The price is typically dependent on the type and material of the window, the location of your property and the size of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What type of window is the most energy-efficient?
A window's energy efficiency is affected by a variety of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.
What do window installers do?
Window installation companies cover the entire process — from replacing your old windows with brand new ones to cleaning up after the installation. Additionally, some companies offer window manufacturing, customization and repairs.
How long does window installation usually take?
Each window takes around 30 minutes to install based on the kind of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
Should I replace my windows all at once?
If your windows are greater than 20 years old, you probably need to replace all of them. By that point, they are often less efficient, draftier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
