How Installing Energy-Efficient Windows in Newmarket Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here are more details about how upgrading your windows could help you:
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Save money on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Upgrading to energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Newmarket, that's about 152 pounds per year on average.
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its value.
Estimated Cost of Window Replacement in Newmarket
Each window replacement company provides various services and has different price points based on several factors.
How Much Do New Windows Cost?
Typically, homeowners in Newmarket can expect that most window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. How much it will cost is based on several factors, such as material, number of windows, the location of your home, type, size and more.
It's also worth keeping in mind that energy-efficient windows will usually cost more initially, but Energy Star estimates that switching out the windows on your Newmarket home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you'll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Another factor that affects the overall cost is the material you choose for your frame. Aluminum frames are generally the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
The first step when considering a window installation is to think about whether you should get a full-frame or pocket installation.
Full-frame installations entail replacing the total window, including the trim, frame and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has considerable damage or rot. Because full-frame installations are more involved, they will increase the total cost. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.
Your window installation company should be able to help you figure out what's best for your needs. In Newmarket, the decision will mostly depend on the age of your windows and if there's any moisture damage. Wood can decay if not maintained properly over the years, so it's a good idea to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Newmarket
EcoWatch reviews are different from most reviews since we evaluate these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in Newmarket and assigned rankings using the following methodology:
Service Area
Because this is a guide for Newmarket, we only included companies that provide services to the city. There are certainly other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Newmarket.
Work Quality
When it comes to new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand of window you opt for. We do give window installers higher marks 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 the majority of customers don't have nice things to say about their service from a certain company, you won't see it featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a sizable investment, so you'll want to make sure that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Newmarket's climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Newmarket window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Newmarket, NH Window Replacement FAQs
What is the average cost to install new windows in a home?
The national average cost of replacing a window is around $600 but can range between $200 and $1,200, depending on a few different factors. The price is generally influenced by the type and material of the window, the size of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What kind of window is the best for energy efficiency?
A window's energy efficiency depends on several factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.
What services do window replacement companies provide?
Window installers travel to your property to remove your old windows and replace them with new ones. Some providers install products made by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is complete.
When is the best time of year to replace windows?
Replacement windows can be installed any time of the year, but warmer weather is typically better. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into the home, so the temperature outside doesn't necessarily matter that much. What's most important is that the weather should be dry.
When is it time to replace your windows?
Windows generally have a lifespan of around 20 to 30 years, but anytime you notice damage on your windows, it's a good time to have an expert take a look at them to determine if they are in need of a repair or replacement.
