How Installing Energy-Efficient Windows in Greenwich Saves You Money
When you switch to energy-efficient windows, you may see some perks, including:
- Decrease your carbon footprint: In Greenwich, you can cut your indirect greenhouse gas emissions by about 286 pounds per year once you install energy-efficient windows.
- Save money on energy bills: Because energy-efficient windows lower the amount of energy used to heat or cool your home, the switch can help you save around $303 annually on your energy bills in Greenwich.
- Protect your investment: If you have a relatively old home, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
Estimated Cost of Window Replacement in Greenwich
Windows come in various shapes and sizes, so costs and services will vary considerably. Here are the typical costs and services that you'll find from the average window installation company.
How Much Do New Windows Cost?
Typically, Greenwich homeowners can anticipate their replacement window installations to range from $250 to $1,200. The average cost sits at approximately $600. But costs vary remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door installations and replacements, which will add extra costs to your project.
Whether or not you want to install energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $303 a year on your energy bills in Greenwich.
Something else that influences the total cost is the material you select for your frame. Aluminum frames are generally the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
The first step of an installation is to clarify whether you should get a full-frame or pocket installation.
A full-frame installation replaces the full window, including the sill, frame, trim and the window panes. As this kind of installation requires more time, it will cost more than a pocket installation. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations more simple and affordable. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.
Your window installation company will be able to recommend the best type for your project. In Greenwich, the choice will mostly depend on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Greenwich
EcoWatch differs from most reviewers since we evaluate these companies through a sustainability lens. We've decided to evaluate the top window installation companies in Greenwich mostly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to reduce your energy 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 Greenwich, we paid more attention to companies that serve the city. There are certainly reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Greenwich.
Work Quality
We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each installer included on this list to make sure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including warranty, quality of installation, quality of parts, cost, professionalism and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers' prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a considerable investment, so you'll want to be certain that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Greenwich's climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Greenwich window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Greenwich, PA Window Replacement FAQs
What is the typical cost to install new windows in a home?
The average cost of replacing a window ranges between $450 and $650. There are several factors that affect how much it costs, including the materials used in designing the windows, the number of windows, how energy-efficient the windows are, styles and sizes of windows, local labor costs and your property's location.
What are the different kinds of windows?
There are various kinds of windows you can get for your home, such as picture windows, awning windows, bay windows, slider windows, transom windows, double-hung and single-hung windows and casement windows.
What do window installation companies do?
Window installation professionals travel to your property to remove your old windows and replace them with new ones. Some companies install products made by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.
How often do you need to replace windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may need to be replaced.
Should I replace my windows all at the same time?
If your windows are more than 20 years old, it's most likely time to replace all of them. At that point, they are typically 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.
