How Installing Energy-Efficient Windows in Henniker Saves You Money
Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to take the plunge and make the switch:
- Save money on electricity bills: After you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% because you'll need less energy to heat or cool your house.
- Better temperature control in your home: Residing in a warm city like Henniker can often mean needing your air conditioner to keep your home cool. Energy-efficient windows can cut back on how hard your AC needs to work to cool your home.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Henniker
Let's go over the cost of installing new windows and the types of services you may need for your home.
How Much Do New Windows Cost?
Even though the national average of replacing one window is around $600, it can range from $200 to $1,200. Costs will differ considerably based on the number of windows you need, the quality of your products, the current condition of your home and your location. Many window companies also offer replacement door installations and other add-ons like shutters, baths, coating and more. Additional services will increase overall project costs.
Keep in mind that energy-efficient windows may come at a higher price point, but Energy Star estimates the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
Another factor that influences the overall cost is the material you select for your frame. Aluminum frames are typically the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most, as 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?
There are typically two kinds of window replacement services: full-frame and pocket installations.
Full-frame installations involve replacing the total window, including the trim, sill and frame. You most likely need a full-frame installation when you want a new style or your window has considerable damage. Full-frame installations are more involved and will increase overall costs. Pocket installations are on the simpler end and won't carry as large a bill because they involve merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.
Your window installer should be able to help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Henniker
The EcoWatch Reviews team differs from other reviewers since we look at these companies through a sustainability lens. Along with energy efficiency, we reviewed each installer and assigned rankings using the following methodology:
Service Area
Because this is a guide for Henniker, we only included companies that cover the city. There are certainly reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Henniker.
Work Quality
When installing new windows, the quality and range of services often plays just as important of a role in insulation and performance as the type of window you choose. 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 the majority of customers don't have nice things to say about their service from a certain window installation company, it won't be featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. That's why window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Henniker's climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Henniker window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Henniker, NH Window Replacement FAQs
How much should window installation cost?
The national average cost of replacing a window is around $600 but can range from $200 to $1,200, depending on a variety of factors. The price is often dependent on the size of the window, the location of your property and the type and material of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What are the kinds of windows?
The most common kinds of windows for homes include: bay windows, awning windows, picture windows, slider windows, transom windows, casement windows and double-hung and single-hung windows.
Do I really have to use a window installation company?
Unless you have home repair skills and have all the tools you need to replace your own windows, we recommend hiring a professional installer. The window installation process is complicated and can take anywhere from four to six hours for a single window. Although it's tempting to try to save money by doing it yourself, hiring a professional is a faster, more efficient and safer option.
How long does window installation take?
Because the average installation time of a window is 30 minutes, around 16 windows can be installed in a typical 8-hour work day.
