Why you can trust EcoWatch
A review of the best window installation companies in Northwood may not seem like the most interesting article on EcoWatch, but trust us, windows have a more direct impact on your life than you might think. The Department of Energy estimates that heat or cool air lost through outdated or drafty windows could represent around 30% of heating and cooling use. In Northwood, where the energy bills are an average of $36 per month, that's almost $$128 per year wasted.
That's also bad for the environment, as the extra energy required by old windows increases your carbon footprint.
We've put together this list of the best installation companies to help you in your research, so you can not only enjoy brand new windows, but also save money on your power bills.

How Installing Energy-Efficient Windows in Northwood Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here are more details about how upgrading your windows could help you:
- Reduce your carbon footprint: By using less energy after you switch to Energy Star certified windows, you'll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Save money on power bills: Once you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% since you'll need less energy to heat or cool your home.
- Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
Estimated Cost of Window Replacement in Northwood
Windows come in different styles, shapes and purposes, so costs and services will differ greatly based on several factors. Below, we go over the average cost and services that you'll find from window installers.
How Much Do New Windows Cost?
The national average cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. These figures vary based on the specifics of your installation, like material, type, size, number of windows, the location of your home and more.
It's important to keep in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Northwood homeowners $435+ a year when replacing single-pane windows.
We recommend getting free quotes from several window installers to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
In general, there are two kinds of window installation 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, such as insulation and drip edges, which increase the total cost of the project. It's also worth noting that it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations are simpler and won't cost as much, as they entail merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.
Your window installation company will be able to help you figure out what's best for your needs. In Northwood, the decision will mostly be based on the age of your home and if there's any moisture damage. Wood can decay if not properly maintained over the years, so it's a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Northwood
The EcoWatch Reviews team is different from most reviewers since we evaluate these companies through a sustainability lens. We have reviewed the top window installers in Northwood primarily based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve Northwood so you can find a quality window installation company near you.
Work Quality
When selecting new windows, the quality and range of services can often play just as important of a role in overall efficiency 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 super important review factor is customer feedback. If most customers don't have positive things to say 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 most services, cheap window companies won't always provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a serious investment, so you'll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Northwood's climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Northwood window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Northwood, NH Window Replacement FAQs
What is the average cost to replace windows?
The national average cost of installing a single window is about $600 but can range between $200 and $1,200, depending on a variety of factors. The price is usually influenced by the type and material of the window, the size of the window and the location of your property. Also, bear 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 different types of windows?
There are several different kinds of windows you can get for your home, including picture windows, bay windows, awning windows, double-hung and single-hung windows, casement windows, slider windows and transom windows.
When should I 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. The process of installing windows is complicated and can take anywhere from four to six hours for one window. Although it's tempting to try to save money by doing it yourself, hiring a professional is a faster, more efficient and much safer alternative.
How long does it generally take to install windows?
Since the average installation time of a window is 30 minutes, around 16 windows can be installed in a typical 8-hour work day.
When is the best time of year to replace windows?
Even though you can install windows any time of year, warmer weather is usually better for installing replacement windows. In addition, it shouldn't be raining, because rain can make the installation more difficult.
