How Installing Energy-Efficient Windows in Reliez Valley Saves You Money
By switching to energy-efficient windows, you 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 once you switch to energy-efficient windows.
- Protect your investment: When your home is on the older side, your windows could also be outdated or drafty.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: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
- Save money 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 lower how much you have to pay, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in Reliez Valley
Windows come in different purposes, shapes and styles, so costs and services will vary remarkably based on your project. Below, we go over the typical cost and services that you can get from window installers.
How Much Do New Windows Cost?
Typically, Reliez Valley homeowners can expect their replacement window installations to range from $250 to $1,200. The most common installations sit at approximately $600. This is because the cost of window installations depend on a variety of factors specific to your home, like the size, material and number of windows you need to install, as well as the location of your property.
Whether or not you want energy-efficient windows is another factor that will determine the cost. These will almost always cost more than other windows, but on the other hand, you can save about $579 a year on your energy bills in Reliez Valley.
Requesting free quotes from several installers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
In regard to window replacements, there are typically two types that your provider will offer: full-frame and pocket installations.
Full-frame installations entail replacing the total window, including the trim, frame and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has considerable damage or rot. Because full-frame installations are more involved, they will raise overall costs. Pocket installations are on the simpler end and won't cost as much because they entail simply 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 not sure which window installation service you should get, your installer can advise you. Typically, the decision depends on factors such as 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 are different from most reviews, as we look at these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Reliez Valley and ranked them based on the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve the Reliez Valley area so you can find a quality window installation company near you.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each installer featured on this list to ensure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including quality of parts, cost, quality of installation, professionalism, warranty and more.
Cost
This one is a give-and-take: as with most services, cheap window installation companies won't always provide the most quality service. On the other hand, we want to make sure we're highlighting companies that provide a range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Reliez Valley's climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Reliez Valley window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Reliez Valley, CA Window Replacement FAQs
How much should window installation cost?
The national average cost of installing one window is around $600 but can range from $200 to $1,200, based on several factors. The price is often dependent on the location of your property, the type and material of the window and the size of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
Which kind of window is the best?
Generally, double-pane windows are more efficient than single-pane windows and windows that don't open are more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification — they're certified energy-efficient by the U.S. Department of Energy.
When do I have to use a window installation company?
Unless you have home repair skills and have the time to replace your own windows, we recommend hiring the pros. The process of installing windows is quite involved and can take anywhere from four to six hours for one window. Although it's tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and much safer alternative.
How long does it usually take to install windows?
Each window takes about 30 minutes to install based on the type of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that need to be installed.
Should I replace all my windows at the same time?
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 only a few windows that are broken or leaky, you can replace just those.
