How Installing Energy-Efficient Windows in Port Washington Saves You Money

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

• Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Save on power bills: Once you install energy-efficient windows, you can see a reduction in your bills by about 12% since you’ll need less energy to heat or cool your house.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if you have an older home.

Estimated Cost of Window Replacement in Port Washington

Let’s take a look at the cost of window replacement and the types of services you may need for your home.

How Much Do New Windows Cost?

Typically, Port Washington homeowners can expect their window replacements to range from $250 to $1,200. The average cost is at approximately $600. How much it will cost is based on several factors, such as type, size, material, number of windows, the location of your home and more.

Whether or not you want to install energy-efficient windows is another factor that will influence the cost. These will typically cost more than other windows, but on the other hand, you can save about $283 a year on your energy bills in Port Washington.

The cost of your window installation will also vary based on the type of material you choose for the frames. Wood windows are typically the most expensive, but it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

When considering window installations, in general there are two types that your installer will have: full-frame and pocket installations.

Full-frame installations are necessary when you want a new style or your window has a lot of rot or deterioration. With this service, your installers will replace the complete window, including the sill, frame and trim. A pocket installation means replacing a window without removing the complete frame, which is usually cheaper than a full-frame installation.

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

How We Choose the Best Window Installers in Port Washington

EcoWatch reviews differ from other reviews because we’re examining these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and ranked them based on the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve the Port Washington area so you can find a quality window installation company near you.

Work Quality

When picking new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand of window you choose. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

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

Cost

This one is a give-and-take: similar to other services, cheap window installers won’t always provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that offer a 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 be certain that investment is well protected. Window installation companies with 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 installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
