How Installing Energy-Efficient Windows in Rocky Hill Saves You Money
By upgrading to energy-efficient windows, you and your family can enjoy several benefits, including:
- Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can reduce your carbon footprint by about 12%, according to Energy Star.
- 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 on energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of household energy use. Switching to energy-efficient windows can help decrease that amount, which helps you save $446 a year on your bills.
- Protect your investment: Keeping your windows up to date 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 Rocky Hill
Windows come in various styles, purposes and shapes, so costs and services will differ greatly depending on your project. Below, we detail the average cost and services that you can get from window replacement companies.
How Much Do New Windows Cost?
Though the average cost to install one window is around $600, it can range anywhere from $200 to $1,200. How much it will cost varies depending on several factors, such as size, material, type, the location of your home, number of windows and more.
Whether or not you want energy-efficient windows is another factor that will affect the cost. These will usually cost more than other windows, but on the other hand, you can save about $446 a year on your energy bills in Rocky Hill.
We recommend getting free quotes from multiple window installers to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
There are typically two kinds of window replacement services: full-frame and pocket installations.
Full-frame installations require replacing the whole 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 a great amount of deterioration. Full-frame installations are more involved and will increase overall costs. A pocket installation involves replacing a window without removing the complete frame, which is usually cheaper than a full-frame installation.
If you’re still debating which type of installation you need, you can ask your provider and get their advice. The decision mostly depends on how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Rocky Hill
The EcoWatch Reviews team is different from other reviewers since we assess these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in Rocky Hill and assigned rankings based on the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve Rocky Hill so you can find the right window installation company near you.
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 technicians are well-qualified and that the company has gotten plenty 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 good feedback about their experience with a certain 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 low when possible. When analyzing providers’ prices, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a sizable investment, so you’ll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Rocky Hill’s climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Rocky Hill window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Rocky Hill, CT Window Replacement FAQs
What is the average cost to replace windows in a home?
The typical cost of installing a window ranges between $450 and $650. There are a variety of factors that influence how much it costs, including local labor costs, the number of windows, styles and sizes of windows, how energy-efficient the windows are, your property’s location and the materials used in designing the windows.
What kind of window is the most energy-efficient?
Generally, double-pane windows are more efficient than single-pane windows and windows that don’t open are more efficient than windows that do. To be sure you’ll get the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — this means they’re certified energy-efficient by the U.S. Department of Energy.
Can I install my own windows?
If you’re handy and have the time and patience to do the job right, you may be able to install your own windows. However, if you don’t have the time or experience, we don’t recommend doing it on your own.
What time of year is a good time to replace my windows?
Although you can install windows any time of year, warmer weather is often better for installing replacement windows. In addition, the weather should be dry, since rain can make the installation harder.
Should I replace my windows all at the same time?
If your windows are more than 20 years old, you most likely need to replace all of them. At that point, they are usually less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.
