How Installing Energy-Efficient Windows in Sunnyside Saves You Money

When you switch to energy-efficient windows, you may see a few benefits, including:

• Save on power bills: After you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll need less energy to heat or cool your house.
• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if you have an older home.
• Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Sunnyside

When considering window installation, each company provides different services and prices. Let’s take a look at some typical costs and services.

How Much Do New Windows Cost?

Generally, homeowners in Sunnyside can expect that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. 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 make your project cost 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 $387 a year on your energy bills in Sunnyside.

We recommend requesting free quotes from multiple window installers to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

When it comes to window replacements, there are typically two types that your installer will offer: full-frame and pocket installations.

Full-frame installations entail replacing the total window, including the sill, frame and trim. You most likely need a full-frame installation when you want to change the style of your windows or your window has considerable deterioration. Because these installations are more involved, they will increase overall costs. A pocket installation entails replacing a window within the frame that’s already there. This means instead of removing the whole unit and rebuilding it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.

If you’re still debating which type of installation you need, you can talk to your installer and get their recommendation. The choice mostly depends on the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Sunnyside

In our search to make your home improvements easier and more eco-friendly in Sunnyside, the EcoWatch team evaluated dozens of companies before landing on these. Along with energy efficiency, we reviewed window companies all across the state and assigned rankings based on the following methodology:

Service Area

Since this is a guide for Sunnyside, we paid more attention to companies that cover the city. There are certainly reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Sunnyside.

Work Quality

When it comes to new windows, the quality and breadth of services often plays just as important of a role in overall efficiency 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

Customer feedback is another super important review factor. If the majority of customers don’t have good things to say about their service from a certain company, it won’t be featured on EcoWatch.

Cost

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

Warranty

As discussed previously, windows are a serious investment, so you’ll want to make sure that investment is protected. Window installation companies that offer lengthy warranties for products, parts and labor 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 are going to earn higher rankings by our standards. We like to see at least ten years of experience.
