How Installing Energy-Efficient Windows in Concord Saves You Money
Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to take the plunge and make the switch:
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out harmful UV rays.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
- More efficient energy usage in your home: Because the winters can get very cold in Concord, homeowners usually depend on their heater a lot. Energy-efficient windows decrease how much heat is lost through your windows, which makes it easier to keep your home warm.
- Save money on energy bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of energy use in your home. Switching to energy-efficient windows can help reduce that number, which helps you save $464 a year on your bills.
Estimated Cost of Window Replacement in Concord
Windows come in varying purposes, styles and shapes, so costs and services will vary greatly depending on several factors. Below, we describe the average cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
Typically, Concord homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost sits at about $600. But prices differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations and replacements, which will add extra costs to your project.
It's important to keep in mind that windows with the best efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Concord homeowners $464+ a year when replacing single-pane windows.
Another factor that affects the overall cost is the material you select for your frame. Aluminum frames are typically the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
When it comes to window installations, there are generally two types that your provider will have: full-frame and pocket installations.
A full-frame installation is a total window replacement. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves other materials, like insulation and drip edges, which increase the total cost of the project. Also worth noting: it's not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any damage or rot, you will likely need a full-frame installation instead.
Your window installation company will be able to help you choose what's best for your needs. In Concord, the decision will mostly depend on how old your windows are and if there's any damage. Wood can decay if not properly maintained 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 Concord
In our search to find the most reliable, eco-friendly window installers in Concord, the EcoWatch Reviews team evaluated many companies before landing on these. We've assessed the top window installers in Concord mainly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows have been shown to cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each company featured in our guide to ensure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If most customers don't have positive feedback about their service from a certain company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installation companies may not provide the most quality service. Still, we want to ensure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a serious investment, so you'll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. 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.
