How Installing Energy-Efficient Windows in Keene Saves You Money

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

  • Reduce your carbon footprint: In Keene, you can reduce your indirect greenhouse gas emissions by about 152 pounds per year once you switch to energy-efficient windows.
  • Save on energy bills: Because energy-efficient windows lower the amount of energy used to heat or cool your home, the switch can help you save around $489 annually on your energy bills in Keene.
  • Protect your investment: If you have a relatively old home, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help raise the value of your property if you decide to sell.
  • Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.

Estimated Cost of Window Replacement in Keene

When researching window installation, each company offers varying services and prices. Let’s take a look at some average costs and services.

How Much Do New Windows Cost?

Generally, Keene homeowners can expect their window installations to range from $250 to $1,200. The average cost is at about $600. But costs will differ significantly based on the quality of your products, the current condition of your home, the number of windows you need and your location. Many window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. Additional services will increase your overall project costs.

Keep in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.

Requesting free quotes from multiple providers is the best way to find out which one will work best for your budget.

What Services do Window Installers Offer?

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

A full-frame installation is a replacement of the total window. It involves taking out the old window, the sill, and the exterior and interior trim. It also involves additional materials, including insulation and drip edges, which raise the total cost of the project. It’s also worth noting that you may have to touch up the paint around the window after a full-frame installation. A pocket installation means replacing a window without taking out the complete frame, which is generally cheaper than a full-frame installation.

If you’re still trying to decide which type of installation you need, you can ask your provider and get their recommendation. The decision mostly depends on how old the frames are and if there’s any damage present.

How We Choose the Best Window Installers in Keene

In our search to find the most reliable, eco-friendly window installers in Keene, the EcoWatch Reviews team evaluated dozens of companies before landing on these. We have decided to assess the best window installers in Keene mostly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find a quality 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 installer featured on this list to make sure 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 patterns in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including quality of parts, professionalism, warranty, quality of installation, cost and more.

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 providers’ prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, 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 labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

Keene, NH Window Replacement FAQs

What is the typical cost to replace windows?

The national average cost to install a single window is around $600 but can range between $200 and $1,200, based on a variety of factors. The price is generally dependent on the size of the window, the location of your property and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

What kind of window is the best for energy efficiency?

A window’s energy efficiency is influenced 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 usually the most energy-efficient since they are certified by the U.S. Department of Energy.

Can I replace my own windows?

If you’re handy and have the time and patience to do the job right, it’s possible to install your own windows. But if you don’t have the time or experience, we don’t recommend it.

How do you know it’s time to replace your windows?

Windows usually have a lifespan of about 20 to 30 years, but anytime you notice damage on your windows, it’s a good time to have them checked by an expert to see if they need any repairs or replacements.

How long does it usually take to install windows?

Since the average installation time of a window is 30 minutes, about 16 windows can be installed during a typical 8-hour work day.
