How Installing Energy-Efficient Windows in North Merrick Saves You Money
When you upgrade to energy-efficient windows, you may see a few perks, including:
- Save money on power bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of residential energy use. Upgrading to energy-efficient windows can help lower that amount, which helps you save some money on your bills.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
- 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.
- Reduce your carbon footprint: By using less energy after you switch to energy-efficient windows, you’ll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in North Merrick
Windows come in all shapes and sizes, so costs and services will vary remarkably. Here are the average costs and services that you can find from window installation companies.
How Much Do New Windows Cost?
On average, homeowners in North Merrick can anticipate that most window installations will range from $250 to $1,200, with the most common installations sitting at about $600. How much it will cost varies based on several factors, including the location of your home, type, number of windows, material, size and more.
Whether or not you opt for energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $283 a year on your energy bills in North Merrick.
Another factor that affects the total cost is the material of the frame you select. Aluminum frames are usually the least pricey and are sturdy and light, 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 and cost somewhere between the other two.
What Services do Window Installers Offer?
Generally, there are two kinds of window installation services companies provide: full-frame and pocket installations.
A full-frame installation is a total window replacement. It involves removing the old window, the sill, and the exterior and interior trim. It also involves other materials, such as insulation and drip edges, which increase the total cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. A pocket installation entails replacing a window within the frame that’s already there. This means instead of tearing out the whole unit and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you’re unsure which kind of window installation service you should get, your installer can help you out. Typically, the decision is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in North Merrick
In our search to make your home improvements easier and more eco-friendly in North Merrick, the EcoWatch team chose the above companies as the best window installation companies in the city. Along with energy efficiency, we evaluated each installer and assigned rankings using the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve North Merrick so you can find the best window installation company near you.
Work Quality
When it comes to new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand of window you choose. 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
We analyzed trends in recent customer feedback to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including quality of parts, quality of installation, warranty, professionalism, cost and more.
Cost
This one is a give-and-take: as with most services, cheap window installers won’t always provide the most quality service. Still, we want to ensure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a significant investment, so you’ll want to be certain that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for a while. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
North Merrick, NY Window Replacement FAQs
What is the typical cost to replace windows in a home?
The national average cost to install one window is around $600 but can range from $200 to $1,200, depending on a variety of factors. The price is generally dependent on the size of the window, the location of your property and the type and material of the window. 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 most common kinds of replacement windows?
There are several different types of windows you can get for your home, including double-hung and single-hung windows, awning windows, casement windows, transom windows, bay windows, slider windows and picture windows.
Can you replace your own windows?
If you’re handy and have the time and patience to do the job right, it’s possible to install your own windows. But if you don’t have the time or know-how, we recommend getting a professional to do it for you.
What time of year should I replace my windows?
Although you can install windows any time of year, warmer weather is typically better for replacing windows. Additionally, the weather should be dry, because rain can make the installation more difficult.
Should I replace all my windows at the same time?
If you want to get more efficient windows and save money on energy costs, replacing all the windows at once is the only way to see a noticeable difference. On the other hand, if you have just a few windows that are broken or drafty, you can replace just those.
