How Installing Energy-Efficient Windows in Concord Saves You Money
By switching to energy-efficient windows, you and your family can benefit in several ways, including:
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out 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: In Concord, you can cut your indirect greenhouse gas emissions by about 117 pounds per year once you upgrade to energy-efficient windows.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, especially if your home is on the older side.
Estimated Cost of Window Replacement in Concord
When considering window installation, each company provides varying services and costs. Let's take a look at some average costs and services.
How Much Do New Windows Cost?
Though the national average of replacing one window is about $600, it can range from $200 to $1,200. Costs will vary considerably depending on the number of windows you need, your location, the current condition of your home and the quality of your products. A lot of window companies also offer replacement door installations and other add-ons like shutters, baths, coating and more. These extra services will increase overall project costs.
It's also worth keeping in mind that energy-efficient windows will cost more upfront, but Energy Star predicts that upgrading the windows on your Concord 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. How much you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Costs will also vary based on the material of your frame. Aluminum frames have the lowest price. They're sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made using 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?
The first step when planning an installation is to figure out whether you should get a full-frame or pocket installation.
Full-frame installations are usually done when you want to change the style of your windows or your window has significant rot or deterioration. With this service, your professionals will replace the full window, including the sill, frame and trim. Pocket installations are on the simpler end and won't carry as large a bill, as they involve merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you may have to get a full-frame installation instead.
If you're still trying to decide which kind of installation you need, you can ask your installer and get their advice. The choice mostly is influenced by how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Concord
EcoWatch reviews differ from most reviews because we're examining these companies through a sustainability lens. We have reviewed the top window replacement companies in Concord mostly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for Concord, we only included companies that serve the city. There are certainly reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Concord.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each company included on this list to ensure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including warranty, cost, quality of installation, professionalism, quality of parts and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers' prices, we gave higher scores 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 be certain 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 a proven track record in the industry. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

There are a variety of factors that influence the price, which include your property's location, the materials used in designing the windows, the number of windows, local labor costs, styles and sizes of windows and how energy-efficient the windows are.
Which type of window should I get?
A window's energy efficiency depends on several factors, including 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 since they are certified by the U.S. Department of Energy.

How long does window installation take?
Each window takes about 30 minutes to install based on the type of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
How do you know it's time to replace your windows?
Windows generally last 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have them checked by an expert to see if they need any repairs or replacements.
