How Installing Energy-Efficient Windows in Strafford Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here's more information on how switching out your windows could benefit you:
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Strafford, that's about 152 pounds per year on average.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.
- Save money on power bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you use less energy.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Strafford
Let's go over the cost of window installation and the types of services offered by installers.
How Much Do New Windows Cost?
Even though the typical of replacing a single window is about $600, it can range anywhere from $200 to $1,200. This is because the cost of window installations depend on several factors specific to your home, like the size, material and number of windows you need to replace, as well as the location of your property.
Whether or not you pick energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $459 a year on your energy bills in Strafford.
Another factor that affects the overall cost is the material of the frame you pick. Aluminum frames are typically the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
The first step of an installation is to think about whether you need a full-frame or pocket installation.
Full-frame installations involve replacing the complete window, including the frame, trim and sill. Full-frame installations are necessary when you want a new style or your window has considerable damage or rot. Full-frame installations are more involved and will increase overall costs. A pocket installation involves replacing a window without removing the complete frame, which tends to be cheaper than a full-frame installation.
Your window installation company can advise you on the best type for your project. In Strafford, the choice will mostly be based on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Strafford
EcoWatch reviews are different from other reviews because we look at these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and ranked them based on the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve Strafford so you can find the best window installation company near you.
Work Quality
When it comes to new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don't have nice things to say about their service from a certain company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window installers may not provide the highest quality service. Still, we want to make sure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. That's why window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Strafford's climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Strafford window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Strafford, NH Window Replacement FAQs
What is the typical cost to replace windows?
The typical cost of installing a single window ranges from $450 to $650. There are a variety of factors that affect how much it costs, including the materials used in designing the windows, styles and sizes of windows, the number of windows, how energy-efficient the windows are, your property's location and local labor costs.
Which kind of window should I get?
A window's energy efficiency depends on a variety of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.
Can you replace your own windows?
If you're handy and have experience with installing a replacement window, it's possible to install your own windows. However, if you don't have the time or experience, we don't recommend it.
How long does it generally take to install windows?
Because the average installation time is 30 minutes per window, around 16 windows can be installed in a typical 8-hour work day.
When is it time to replace your windows?
Windows generally last around 20 to 30 years, but anytime you notice damage on your windows, it's a good idea to have them looked at by an expert to see if they are in need of a repair or replacement.
