How Installing Energy-Efficient Windows in Mammoth Lakes Saves You Money
By switching to energy-efficient windows, you and your family can enjoy several benefits, including:
- Save on power bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of household energy use. Replacing your windows with energy-efficient models can help decrease how much you have to pay, therefore saving you about 12% more on your bills.
- Reduce your carbon footprint: By using less energy after switching to energy-efficient windows, you'll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
- Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Mammoth Lakes
Let's take a look at the cost of window installation and the kinds of services offered by installers.
How Much Do New Windows Cost?
According to our research, the national average cost to install a single window is around $600. However, window installation costs can range from $200 to $1,200 a window. But costs will differ significantly depending on your location, the current condition of your home, the quality of your products and the number of windows you need. Many window companies also offer replacement door installations and other add-ons like baths, shutters, coating and more. These extra services will increase your overall project costs.
It's important to bear in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Mammoth Lakes homeowners $634+ a year when replacing single-pane windows.
The cost of your window installation will also vary depending on the kind of material you choose for the frames. Wood windows are generally the most expensive, although it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
There are typically two kinds of window replacement services: full-frame and pocket installations.
Full-frame installations are usually recommended when you want a new style or your window has significant rot. With this service, your professionals will replace the entire window, including the trim, frame and sill. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are on the simpler end and won't cost as much, but you can't do this type of installment if you have any pre-existing rot or water damage.
Your window installation company will be able to advise you on the best type for your project. In Mammoth Lakes, the choice will mostly depend on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Mammoth Lakes
The EcoWatch Reviews team differs from most reviewers since we look at these companies through a sustainability lens. Along with energy efficiency, we reviewed window companies all across the state and assigned rankings based on the following methodology:
Service Area
Since this is a guide for Mammoth Lakes, we only included companies that cover the city. There are certainly other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Mammoth Lakes.
Work Quality
When picking new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the type of window you get. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don't have positive things to say about their experience with a certain window installation company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window companies won't always provide the most quality service. Still, we want to ensure we're highlighting companies that offer a wide range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. That's why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, 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.
Mammoth Lakes, CA Window Replacement FAQs
How much should a window install cost?
The national average cost to replace a single window is about $600 but can range between $200 and $1,200, based on several factors. The price is usually influenced by the location of your property, the type and material of the window and the size of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What are the most common types of replacement windows?
The most common types of windows for homes are picture windows, transom windows, awning windows, casement windows, slider windows, double-hung and single-hung windows and bay windows.
What services do window installation companies offer?
Window installers will do the entire process — from replacing your old windows with brand new ones to cleaning up afterward. Additionally, some companies offer window manufacturing, customization and repairs.
What time of year is the best time to replace my windows?
Replacement windows can be installed at any time, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into your home, so the temperature outside isn't necessarily a big factor. What's more important than the temperature is that the weather should be dry.
Should I replace my windows all at once?
If you want to get more efficient windows and save money on your energy bills, replacing all of the windows together is the only way to gain that benefit. However, if you have just a few windows that are broken or drafty, you can replace just those.
