How Installing Energy-Efficient Windows in Nantucket Saves You Money

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

• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Protect your investment: When you have an older home, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its value.
• Save on energy bills: Since energy-efficient windows lower how much energy you need to heat or cool your home, the switch can help you save about $280 annually on your energy bills in Nantucket.
• Reduce your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by about 139 pounds.

Estimated Cost of Window Replacement in Nantucket

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

How Much Do New Windows Cost?

On average, homeowners in Nantucket can expect that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. Costs will vary significantly based on the number of windows you need, the current condition of your home, your location and the quality of your products. Many window companies also offer door installations and other add-ons like shutters, baths, coating and more. These extra services will increase your overall project costs.

It's also worth bearing in mind that energy-efficient windows will typically cost more upfront, but Energy Star predicts that upgrading the windows on your Nantucket home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you'll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

What Services do Window Installers Offer?

The first step when planning a replacement is to clarify whether you need a full-frame or pocket installation.

Full-frame installations are usually recommended when you want a new style or your window has significant deterioration. With this service, your installers will replace the entire window, including the sill, trim and frame. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any damage or rot, you will most likely need a full-frame installation instead.

If you're unsure which kind of window installation service you need, your installer should be able to assist you. Generally, the decision depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Nantucket

In our hunt to find the most reliable, eco-friendly window installers in Nantucket, the EcoWatch Reviews team examined dozens of companies before settling on these. We have evaluated the top window replacement companies in Nantucket mainly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each company featured on this list to ensure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews to determine the companies with the most customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including professionalism, warranty, quality of parts, cost, quality of installation and more.

Cost

This one is a give-and-take: similar to other services, cheap window companies may not provide the most quality service. Still, 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 serious investment, so you'll want to make sure that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of Nantucket's climate, homeowners need to be wary of low efficiency, water damage and rot. We factored in local experience to reflect the ability of Nantucket window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
