How Installing Energy-Efficient Windows in Syosset Saves You Money

Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to take the plunge and make the switch:

• Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
• Decrease your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by about 307 pounds.
• Save on power bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
• Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in Syosset

Windows come in different shapes and sizes, so costs and services will differ greatly. Here are the average costs and services that you can find from window installation companies.

How Much Do New Windows Cost?

Typically, Syosset homeowners can anticipate their window installations to range from $250 to $1,200. The average cost is at approximately $600. But costs will vary significantly depending on your location, the current condition of your home, the quality of your products and the number of windows you need. A lot of window companies also offer door installations and other add-ons like baths, coating, shutters and more. Additional services will increase overall project costs.

With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Syosset homeowners $283+ a year after replacing single-pane windows.

We recommend requesting free quotes from several window installation companies to find the one that works best for your budget.

What Services do Window Installers Offer?

Generally, there are two types of window replacement services companies provide: full-frame and pocket installations.

A full-frame installation is a replacement of the full window. This service involves removing the old window, the windowsill, and the exterior and interior trim. It also involves additional materials, such as insulation and drip edges, which raise the overall 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. A pocket installation entails replacing a window within the existing frame. This means instead of taking out the whole window and reinstalling it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company will be able to help you decide what’s best for your needs. In Syosset, the decision will mostly be based on the age of your windows and if there’s any damage. Wood can decay if not maintained properly over the years, so it’s good to have a professional evaluate your frames and window sills.

We’ve reviewed the top window installers in Syosset mostly 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 can cut your power 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 Syosset, we only included companies that cover the city. There are other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Syosset.

Work Quality

When choosing 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 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

We analyzed trends in recent customer feedback to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including quality of installation, cost, professionalism, quality of parts, warranty and more.

Cost

This one is a give-and-take: similar to most services, cheap window installation companies are not going to provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that offer a wide range of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed previously, windows are a hefty investment, so you’ll want to make sure that investment is protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a proven track record in the industry. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
