How Installing Energy-Efficient Windows in Lakeport Saves You Money
By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, including:
- Save money on energy bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% because you'll use less energy to heat or cool your home.
- Decrease your carbon footprint: In Lakeport, you can reduce your indirect greenhouse gas emissions by about 117 pounds per year when you switch to energy-efficient windows.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if you have an older home.
Estimated Cost of Window Replacement in Lakeport
Windows come in varying purposes, styles and shapes, so costs and services will vary greatly depending on your project. Below, we describe the average cost and services that you can get from window installers.
How Much Do New Windows Cost?
Generally, Lakeport homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at about $600. But costs vary remarkably 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 provide door replacements, which will add extra costs to your project.
It's also worth keeping in mind that energy-efficient windows will cost more initially, but Energy Star predicts that upgrading the windows on your Lakeport home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you'll save by upgrading 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 installers to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
In general, there are two kinds of window replacement services you can get: 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 new style for your windows or when it has significant damage. Full-frame installations require more time and labor and will increase overall costs. A pocket installation means replacing a window without taking out the entire frame, which is generally cheaper than a full-frame installation.
If you're not sure which type of window installation service you need, your installer should be able to help you out. Generally, the decision is influenced by 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 Lakeport
EcoWatch reviews differ from other reviews, as we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings using the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find the best 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 in our guide to make sure its technicians are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don't have good things to say about their service from a certain window installation company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window companies may not provide the highest quality service. On the other hand, 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
Protecting your investment in new windows is important. For that reason, window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a proven track record in the industry. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Lakeport, CA Window Replacement FAQs
How much does window installation cost?
The national average cost to replace a single 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, keep in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What type of window is the best for energy efficiency?
Generally, double-pane windows are more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. To be sure you'll get the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — this means they're certified energy-efficient by the U.S. Department of Energy.
When should I use a window installation company?
Unless you have experience with home improvement projects and have the time needed to replace your own windows, we recommend hiring the pros. The window installation process is complex and can take anywhere from four to six hours for a single window. Although it's tempting to try to save some money by doing it yourself, hiring a professional is a faster, more efficient and much safer alternative.
How long does window installation typically take?
Each window takes about 30 minutes to install depending on the type of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
What time of year is a good time to replace my windows?
Replacement windows can be installed during any season, but autumn might be best. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your house, so the temperature outside doesn't necessarily matter that much. What's more important than the temperature is that the weather should be dry.
