How Installing Energy-Efficient Windows in Reliez Valley Saves You Money
By upgrading to energy-efficient windows, you and your family can benefit in several ways, including:
- Decrease your carbon footprint: In Reliez Valley, you can lower your indirect greenhouse gas emissions by about 117 pounds per year when you upgrade to energy-efficient windows.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- 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 Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
- Save on power bills: After you upgrade to 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 house.
Estimated Cost of Window Replacement in Reliez Valley
Let's take a look at the cost of window installation and the kinds of services you may need for your home.
How Much Do New Windows Cost?
According to our research, the typical cost of replacing a single window is about $600. However, window replacement costs can range from $200 to $1,200 for each window. This is because the cost of window installations depend on several factors specific to your home, such as the size, material and number of windows you need to install, as well as where your property is located.
Whether or not you pick energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $657 a year on your energy bills in Reliez Valley.
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 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?
There are typically two types of window replacement services: full-frame and pocket installations.
Full-frame installations require replacing the full window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has significant rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations are simpler and won't cost as much, as they involve merely 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.
If you're unsure which kind of window installation service you need, your installer can advise you. Typically, the decision depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Reliez Valley
EcoWatch reviews differ from most reviews because we examine these companies through a sustainability lens. We've reviewed the top window installers in Reliez Valley primarily based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to lower energy 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 Reliez Valley, we only included companies that serve the city. There are certainly other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Reliez Valley.
Work Quality
When picking new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand of window you opt for. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don't have good 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 are not going to provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that provide a variety 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 that offer lengthy warranties for products, parts and installation (aka workmanship) 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.
Reliez Valley, CA Window Replacement FAQs
What is the typical cost to install windows?
The national average cost of replacing one window is about $600 but can range between $200 and $1,200, depending on a few different factors. The price is generally influenced by the type and material of the window, the location of your property and the size of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What type of window is the best for energy efficiency?
A window's energy efficiency is affected by a variety of 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 replacement companies provide?
Window installation professionals cover the entire process — from replacing your old windows with new ones to cleaning up after the windows have been put in place. In addition, many companies offer window manufacturing, customization and repairs.
When is it time to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to open or close, they may need to be replaced.
Should I replace all my windows at once?
If your windows are greater than 20 years old, it's probably time to replace all of them. By that point, they are often less efficient, draftier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
