How Installing Energy-Efficient Windows in Merrimack Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to take the plunge and make the switch:
- Save on power bills: Since energy-efficient windows decrease the amount of energy needed to heat or cool your home, the switch can help you save about $463 annually on your energy bills in Merrimack.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Merrimack, that’s about 152 pounds per year on average.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Merrimack
Let’s go over the cost of window replacement and the kinds of services you may need for your home.
How Much Do New Windows Cost?
On average, homeowners in Merrimack can anticipate that most window installations will range from $250 to $1,200, with the average cost sitting at around $600. These numbers are based on specific characteristics of your installation, including the location of your home, type, size, material, number of windows and more.
Whether or not you choose energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $463 a year on your energy bills in Merrimack.
Asking for free quotes from several companies is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
Generally, there are two types of window replacement services companies offer: full-frame and pocket installations.
A full-frame installation is a replacement of the total window. It involves removing the old window, the sill, and the exterior and interior trim. It also involves additional materials, like insulation and drip edges, which raise the overall cost of the project. It’s also worth noting that it’s not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any damage or rot, you will most likely need a full-frame installation instead.
If you’re not sure which type of window installation service you need, your installer can advise you. Typically, the decision is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Merrimack
In our search to make your home improvements easier and more eco-friendly in Merrimack, the EcoWatch Reviews team evaluated many companies before deciding on these. We’ve reviewed the top window installation companies in Merrimack mostly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows have been shown to lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Because this is a guide for Merrimack, we only included companies that cover the city. There are certainly other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Merrimack.
Work Quality
We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer featured in our guide to ensure its contractors are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have good things to say about their experience with a certain installer, it won’t be featured on EcoWatch.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Merrimack’s climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Merrimack window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Merrimack, NH Window Replacement FAQs
What is the average cost to install new windows?
The national average cost to install a single window is around $600 but can range from $200 to $1,200, based on a few different factors. The price is usually influenced by the location of your property, the size of the window and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
Which type of window should I get?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you’ll get the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — that means they’re certified energy-efficient by the U.S. Department of Energy.
Can you replace your own windows?
While it is possible to install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Using a window replacement company can help ensure that the installation is done properly and that you won’t have to spend the time and effort to do it yourself.
Should I replace all my windows at once?
If your windows are more than 20 years old, you probably need to replace all of them. At that point, they are typically less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.
How long does it take to install windows?
Each window takes around 30 minutes to install based on the type of window. However, the window installation can take two days or more if you have a lot of windows that must be installed.
