How Installing Energy-Efficient Windows in Derby Saves You Money
Energy-efficient windows can provide benefits in several ways. Here are a few reasons you may want to consider making the switch:
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 147 pounds per year on average.
- 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.
- Save money on energy bills: Switching to energy-efficient windows lowers your energy bills by about 12% because you need less energy.
Estimated Cost of Window Replacement in Derby
Windows come in varying shapes and sizes, so costs and services will vary remarkably. Here are the typical costs and services that you can find from the average window installation company.
How Much Do New Windows Cost?
According to our market research, the national average cost to install a single window is around $600. However, window installation costs can range from $200 to $1,200 for each window. How much it will cost you varies based on several factors, including the location of your home, number of windows, size, type, material and more.
It's also worth noting that energy-efficient windows will cost more initially, but Energy Star estimates that upgrading the windows on your Derby home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you'll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
The cost of your window installation will also vary based on the type of window material you choose for the frames. Wood windows are generally the most expensive, though it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
There are generally two kinds of window installation services: full-frame and pocket installations.
Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has a great amount of rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.
If you're still trying to decide which kind of installation you should get, you can consult with your installer and get their advice. The choice mostly is influenced by the age of your window frames and if there's any damage.

How We Choose the Best Window Installers in Derby
EcoWatch reviews are different from other reviews since we assess these companies through a sustainability lens. We've decided to assess the top window replacement companies in Derby 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 energy 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 installation companies that serve a wide variety of states and cities so you can find the right window installation company near you.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each company included on this list to make sure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including quality of installation, professionalism, quality of parts, cost, warranty and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a hefty investment, so you'll want to be certain that investment is well protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Derby's climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Derby window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Derby, CT Window Replacement FAQs
How much does window installation cost?
The national average cost to replace a window is about $600 but can range from $200 to $1,200, based on several factors. The price is generally influenced by the location of your property, the type and material of the window and the size of the window. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What are the most common kinds of replacement windows?
There are various types of windows you can get for your home, such as picture windows, awning windows, casement windows, slider windows, transom windows, double-hung and single-hung windows and bay windows.
When do I have to use a window installation company?
Unless you're handy and have the time to replace your own windows, we recommend hiring a professional installer. The window installation process is quite involved and can take anywhere from four to six hours for a single window. Although it's tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and much safer option.
Should I replace my windows all at the same time?
If you want to get more efficient windows and save money on energy costs, replacing all your windows at the same time is the only way to see a noticeable difference. However, if you have only a few windows that are damaged or drafty, you can replace just those.
