20 Best Window Companies in Rockville Centre, NY (2025 Reviews)

How Installing Energy-Efficient Windows in Rockville Centre Saves You Money

When you switch to energy-efficient windows, you may see several benefits, such as:

• Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
• Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading and repairing your windows is an important part of maintaining your property and its value.
• Decrease your carbon footprint: In Rockville Centre, you can cut your indirect greenhouse gas emissions by about 307 pounds per year once you switch to energy-efficient windows.
• Save on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of household energy use. Upgrading to energy-efficient windows can help reduce that amount, which helps you save $283 a year on your bills.

Estimated Cost of Window Replacement in Rockville Centre

Windows come in all shapes and sizes, so costs and services will vary tremendously. 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?

Though the average cost to replace a single window is about $600, it can range from $200 to $1,200. But costs vary remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door replacements, which will add extra costs to your project.

Keep in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.

Something else that influences the total cost is the material you pick for your frame. Aluminum frames are usually the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames are the most expensive, 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?

In general, there are two types 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 windowsill, and the exterior and interior trim. It can also involve other materials, like insulation and drip edges, which increase the overall cost of the project. It’s also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation means replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.

Your window installer should be able to help you choose which type of installation you should get.

How We Choose the Best Window Installers in Rockville Centre

EcoWatch is different from other reviewers, as we assess these companies through a sustainability lens. We’ve evaluated the best window installers in Rockville Centre primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for Rockville Centre, we gave more points to 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 Rockville Centre.

Work Quality

We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each installer featured in our guide to make sure its contractors are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another very important review factor. If most customers don’t have positive things to say about their experience with a certain installer, 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, windows are a significant investment, so you’ll want to be certain that investment is protected. Window installation companies that give you 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 quite some time. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
