How Installing Energy-Efficient Windows in Holtsville Saves You Money
By switching to energy-efficient windows, you and your family can benefit in several ways, such as:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its value.
- Save on power bills: Since energy-efficient windows lower how much energy you need to heat or cool your home, the switch can help you save about $215 annually on your energy bills in Holtsville.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Holtsville, that's about 307 pounds per year on average.
Estimated Cost of Window Replacement in Holtsville
Windows come in varying shapes and sizes, so costs and services will differ considerably. Here are the average costs and the primary services that you'll find from the average window installation company.
How Much Do New Windows Cost?
According to our research, the average cost to install a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. How much it will cost varies based on several factors, including number of windows, material, the location of your home, type, size and more.
Keep in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.
How much your window installation costs will also vary depending on the kind of material you choose for the frames. Wood windows are usually the most expensive, but it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
In regard to window replacements, there are generally two kinds that your installer will offer: 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 additional materials, like insulation and drip edges, which raise the total cost of the project. Also worth noting: it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
If you're still debating which type of installation you need, you can talk to your installer and get their advice. The choice mostly depends on how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Holtsville
EcoWatch reviews are different from most reviews, as we assess these companies through a sustainability lens. We've reviewed the best window installation companies in Holtsville mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for Holtsville, we gave more points to companies that serve the city. There are certainly other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Holtsville.
Work Quality
When selecting new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand of window you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don't have nice feedback about their service from a certain window installation company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window installation companies may not provide the highest quality service. Still, we want to make sure we're highlighting companies that provide a range 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 protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a good track record in the industry. 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.
Holtsville, NY Window Replacement FAQs
What is the typical cost to replace windows?
The national average cost of replacing a single window is around $600 but can range from $200 to $1,200, depending on several factors. The price is typically influenced by the size of the window, the location of your property and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
Which kind of window should I get?
A window's energy efficiency is affected by several factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.
Can you replace your own windows?
While it is possible to install your own windows, doing so requires a lot of time and experience with home improvement projects. Hiring a professional can help guarantee that the job is done properly and that you can avoid spending the time and effort of doing it yourself.
How long does it usually take to install windows?
Each window takes around 30 minutes to install based on the kind of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
How often should you replace windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to operate, they may be in need of replacement.
