How Installing Energy-Efficient Windows in Sunapee Saves You Money

Energy-efficient windows can offer benefits in more than one way. Here are a few reasons you may want to take the plunge and make the switch:

  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
  • Save money on electricity bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you need less energy.
  • Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Sunapee, that's about 152 pounds per year on average.
  • Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.

Estimated Cost of Window Replacement in Sunapee

Windows come in different styles, shapes and purposes, so costs and services will vary considerably based on your project. Below, we detail the typical cost and services that you can get from window installers.

How Much Do New Windows Cost?

According to our market research, the national average cost to replace a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. This is because the cost of window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to install, as well as where your property is located.

Whether or not you opt for 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 $520 a year on your energy bills in Sunapee.

The cost of your window installation will also vary based on the kind of material you choose for the frames. Wood windows are usually the most expensive, but it depends if 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?

The first thing to ask yourself when getting new windows is: Do you need a full-frame installation or a pocket installation?

Full-frame installations are usually recommended when you want to change the style of your windows or your window has a lot of deterioration. With this service, your installers will replace the total window, including the frame, sill and trim. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

Your window replacement company should be able to help you figure out what's best for your needs. In Sunapee, the decision will mostly be based on the age of your home and if there's any damage. Wood can decay if not maintained properly over the years, so it's a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Sunapee

The EcoWatch Reviews team differs from most reviewers, as we examine these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings based on the following methodology:

Service Area

Because this is a guide for Sunapee, we gave more points to companies that cover the city. There are certainly reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Sunapee.

Work Quality

When installing 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 get. 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

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have positive feedback about their service from 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 try to keep costs as low as possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

Protecting your investment in new windows is important to many homeowners. That's why window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a proven track record in the industry. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

Sunapee, NH Window Replacement FAQs

How much does a window install cost?

The typical cost to replace a window can range from $450 to $650. There are many factors that influence the price, including your property's location, the number of windows, styles and sizes of windows, the materials used in designing the windows, how energy-efficient the windows are and local labor costs.

What are the different kinds of windows?

The most common types of windows for homes include: transom windows, bay windows, slider windows, awning windows, picture windows, casement windows and double-hung and single-hung windows.

Can I install my own windows?

If you're handy and have experience with installing a replacement window, you may be able to install your own windows. However, if you don't have the time or skills, we recommend getting a professional to do it for you.

How long does it usually take to install windows?

Each window takes around 30 minutes to install depending on the type of window. However, the window installation can take two days or more if you have a lot of windows that need to be installed.

Should I replace all my windows at the same time?

If your windows are more than 20 years old, it's probably time to replace all of them. By that point, they are often less efficient, draftier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
