How Installing Energy-Efficient Windows in Mcnair Saves You Money
By switching to energy-efficient windows, you and your family can take advantage of several benefits, such as:
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
- Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can lower your carbon footprint by about 12%, according to Energy Star.
- Protect your valuables from fading: When you upgrade 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.
- Save on energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of energy use in your home. Installing energy-efficient windows can help reduce that number, which helps you save some money on your bills.
Estimated Cost of Window Replacement in Mcnair
Let's take a look at the cost of window replacement and the kinds of services you may need for your home.
How Much Do New Windows Cost?
The national average cost to install one window is about $600 but can range from $200 to $1,200. But prices differ considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations and replacements, which carry a higher price tag.
It's also worth bearing in mind that energy-efficient windows will typically cost more initially, but Energy Star estimates that switching out the windows on your Mcnair home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you'll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
We advise requesting free quotes from several window installation companies to find the one that works best for your budget.
What Services do Window Installers Offer?
In general, there are two kinds of window replacement services companies offer: full-frame and pocket installations.
Full-frame installations are usually recommended when you want to change the style of your windows or your window has a lot of deterioration. With this service, your installers will replace the entire window, including the sill, trim and frame. Pocket installations are on the simpler end and won't cost as much, as they involve simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.
Your window installation company will be able to advise you on the best type for your project. In Mcnair, the decision will mostly be influenced by how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Mcnair
In our hunt to make your home improvements easier and more eco-friendly in Mcnair, the EcoWatch Reviews team examined dozens of companies before deciding on these. We have assessed the best window installation companies in Mcnair mainly 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 have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Because this is a guide for Mcnair, we gave more points to companies that cover the city. There are certainly other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Mcnair.
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 included on this list to ensure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don't have positive feedback about their service from a certain installer, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installation companies are not going to provide the most quality service. Still, we want to ensure we're highlighting companies that provide a wide range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a significant investment, so you'll want to make sure that investment is protected. Window installation companies that have 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 are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Mcnair, VA Window Replacement FAQs
How much does window installation cost?
The typical cost of installing one window ranges from $450 to $650. There are many factors that influence how much it costs, such as the materials used in designing the windows, how energy-efficient the windows are, your property's location, styles and sizes of windows, local labor costs and the number of windows.
What kind of window is the best for energy efficiency?
A window's energy efficiency is influenced by several 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 since they are certified by the U.S. Department of Energy.
What services do window installation companies offer?
Window installation professionals travel to your home to remove your old windows and replace them with new ones. Some companies install products sold by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.
How long does window installation typically take?
Each window takes around 30 minutes to install depending 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.
Should I replace my windows all at once?
If you're upgrading your windows to save on your energy bills, replacing all of your windows at once is the only way to see a noticeable difference. On the other hand, if you have just a few windows that are damaged or leaky, you can replace just those.
