How Installing Energy-Efficient Windows in Durham Saves You Money

When you upgrade to energy-efficient windows, you may see a few perks, including:

  • Save on power bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Installing energy-efficient models can help decrease that amount, therefore saving you about 12% more on your bills.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help increase the value of your property if you decide to sell.
  • Reduce your carbon footprint: In Durham, you can reduce your indirect greenhouse gas emissions by about 152 pounds per year when you install energy-efficient windows.

Estimated Cost of Window Replacement in Durham

Each window installation company offers various services and has varying prices depending on several factors.

How Much Do New Windows Cost?

According to our market research, the typical cost to replace a single window is about $600. However, window installation costs can range from $200 to $1,200 a window. This is due to the fact that window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to install, as well as the location of your property.

With windows, efficiency is one of the most important factors for most homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — particularly during the winter — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Durham homeowners $459+ a year after replacing single-pane windows.

Costs will also vary depending on the material of your frame. Aluminum frames have the lowest price. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

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

A full-frame installation replaces the entire window, such as the windowsill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will cost more than a pocket installation. A pocket installation entails replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.

If you're still debating which kind of installation to get, 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.

How We Choose the Best Window Installers in Durham

In our search to find the most reliable, eco-friendly window installers in Durham, EcoWatch examined many companies before deciding on these. Along with energy efficiency, we assessed window companies all across the state and ranked them using the following methodology:

Service Area

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

Work Quality

When choosing new windows, the quality and range of services can often play 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

We analyzed trends in recent customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including cost, quality of installation, professionalism, warranty, quality of parts and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed previously, windows are a hefty investment, so you'll want to make sure that investment is protected. Window installation companies that give you 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 will earn higher rankings by our standards. We like to see at least ten years of experience.

Durham, NH Window Replacement FAQs

How much should a window install cost?

The national average cost to replace one window is about $600 but can range from $200 to $1,200, depending on a few different factors. The price is generally dependent on the size of the window, the type and material of the window and the location of your property. Also, keep 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 kind of window is the most energy-efficient?

A window's energy efficiency depends on a variety of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.

Can you replace your own windows?

If you're handy and have experience with similar home improvement projects, you may be able to install your own windows. However, if you don't have the time or know-how, we recommend hiring a professional.

When is it time to replace your windows?

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

Should I replace all my windows at the same time?

If your windows are greater than 20 years old, it's probably time to replace all of them. At that point, they are typically less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.
