How Installing Energy-Efficient Windows in Kingston Saves You Money

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

  • Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
  • Save on electricity bills: After you install energy-efficient windows, you can expect a reduction in your bills by about 12% since you'll use less energy to heat or cool your home.
  • Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can reduce your carbon footprint by about 12%, according to Energy Star.
  • Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Kingston

Windows come in different shapes, purposes and styles, so costs and services will vary greatly based on your project. Below, we describe the typical cost and services that you'll find from window replacement companies.

How Much Do New Windows Cost?

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

It's important to remember that windows with higher efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Kingston homeowners $435+ a year when replacing single-pane windows.

Requesting free quotes from several companies is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

The first question to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?

A full-frame installation replaces the total window, including the sill, frame, trim and the window panes. As this type of installation is more involved, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won't carry as large a bill, but you can't do this type of installment if you have any pre-existing rot or water damage.

If you're still trying to decide which type of installation you need, you can ask your installer and get their recommendation. The decision mostly is influenced by how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Kingston

In our search to find the most reliable, eco-friendly window installers in Kingston, the EcoWatch team landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we reviewed window companies all across the state and assigned rankings based on the following methodology:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve the Kingston area so you can find the best window installation company near you.

Work Quality

We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each company featured on this list to ensure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don't have good feedback about their experience with a certain window installation company, it won't be featured on EcoWatch.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed, windows are a considerable investment, so you'll want to be certain that investment is well 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 proven track record in the industry. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Kingston, NH Window Replacement FAQs

How much should window installation cost?

The national average cost of replacing one window is around $600 but can range between $200 and $1,200, depending on several factors. The price is often influenced by the size of the window, the type and material of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

What type of window is the best for energy efficiency?

A window's energy efficiency is affected by a variety of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.

What services do window installation companies do?

Window installers go to your home to remove your old windows and replace them with new ones. Some companies install products manufactured by other companies, whereas others install their own windows. The installer will also clean up after the installation is done.

When is it time to replace your windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to operate, they may be in need of replacement.

Should I replace all my windows at the same time?

If you want to get more efficient windows and save money on your energy bills, replacing all of the windows at once is the only way to gain that benefit. On the other hand, if you have only one or two windows that are broken or drafty, you can replace just those.
