How Installing Energy-Efficient Windows in Farmington Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here are more ways upgrading your windows could help you:
- Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its value.
- Better temperature control in your home: Energy-efficient windows can reduce how hard your AC needs to work to cool your home.
- Better temperature control in your home: Residing in a cold place like Farmington can often mean depending on your heater to keep your house cool. Energy-efficient windows can cut back on how hard your heating system needs to work to heat your home.
- Save on power bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Installing energy-efficient models can help decrease how much you have to pay, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in Farmington
Each window replacement company provides various services and has varying costs based on a few factors.
How Much Do New Windows Cost?
Typically, Farmington homeowners can expect their window replacements to range from $250 to $1,200. The average cost is at around $600. But costs will vary considerably depending on the quality of your products, the number of windows you need, your location and the current condition of your home. A lot of window companies also offer replacement door installations and other add-ons like baths, coating, shutters and more. Additional services will increase your overall project costs.
It's important to remember that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Farmington homeowners $495+ a year when replacing single-pane windows.
Costs will also vary based on the material you choose for your window frames. Aluminum frames have the lowest price. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
When it comes to window replacements, in general there are two kinds that your installer will have: full-frame and pocket installations.
Full-frame installations require replacing the full window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has a great amount of rot or deterioration. Full-frame installations are more comprehensive and will increase overall costs. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
If you're not sure which kind of window installation service you should get, your installer can assist you. In general, the choice depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Farmington
EcoWatch differs from most reviewers since we evaluate these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and ranked them based on the following methodology:
Service Area
Because this is a guide for Farmington, we gave more points to companies that cover the city. There are other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Farmington.
Work Quality
We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each company featured on this list to make sure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very 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
This one is a give-and-take: similar to other services, cheap window installation companies won't always provide the most quality service. Still, we want to make sure we're highlighting companies that offer a wide range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. That's why window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Farmington, ME Window Replacement FAQs
How much does window installation cost?
The typical cost to install a single window can range from $450 to $650. There are many factors that influence the cost, which include local labor costs, the materials used in designing the windows, the number of windows, how energy-efficient the windows are, your property's location and styles and sizes of windows.
What are the different types of windows?
The most common kinds of windows for homes include: picture windows, casement windows, double-hung and single-hung windows, awning windows, transom windows, slider windows and bay windows.
When do I have to use a window installation company?
You should hire a window installation company whenever you need to upgrade your windows. Installing windows is a complicated process that can be difficult and time-consuming, so it's best left to the professionals.
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. Additionally, it shouldn't be raining, as rain can make the installation more difficult.
Should I replace my windows all at the same time?
If your windows are more than 20 years old, you probably need to replace all of them. At that point, they are often less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.
