How Installing Energy-Efficient Windows in Lathrop Saves You Money
By upgrading to energy-efficient windows, you and your family can benefit in several ways, such as:
- Save on energy bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of household energy use. Installing energy-efficient windows can help lower that number, which helps you save $661 a year on your bills.
- Reduce your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 117 pounds.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
Estimated Cost of Window Replacement in Lathrop
Windows come in various styles, purposes and shapes, so costs and services will vary tremendously depending on several factors. Below, we go over the typical cost and services that you'll find from window installers.
How Much Do New Windows Cost?
Though the national average of installing a single window is around $600, it can range anywhere from $200 to $1,200. But costs will vary significantly depending on your location, the current condition of your home, the quality of your products and the number of windows you need. A lot of window companies also offer door installations and other add-ons like shutters, baths, coating and more. These extra services will increase overall project costs.
It's also worth bearing in mind that energy-efficient windows will almost always cost more initially, but Energy Star predicts that switching out the windows on your Lathrop home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you'll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Requesting free quotes from several companies is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
There are typically two types of window replacement services: full-frame and pocket installations.
Full-frame installations are usually done when you want a new style or your window has significant rot or deterioration. With this service, your professionals will replace the full window, including the frame, sill and trim. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.
If you're unsure which kind of window installation service you should get, your installer can assist you. Generally, the choice is based 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 Lathrop
EcoWatch differs from other reviewers since we're examining these companies through a sustainability lens. We have decided to assess the top window installation companies in Lathrop 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 can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
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 a quality window installation company near you.
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 in our guide to ensure its technicians are well-qualified and that the company has received tons 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 positive feedback about their service from a certain company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window installation companies may not provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a serious investment, so you'll want to be certain that investment is protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Lathrop's climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Lathrop window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Lathrop, CA Window Replacement FAQs
What is the typical cost to install new windows in a home?
The average cost of installing one window ranges between $450 and $650. There are many factors that affect how much it costs, including styles and sizes of windows, local labor costs, the materials used in designing the windows, your property's location, the number of windows and how energy-efficient the windows are.
What kind of window is the most energy-efficient?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. To be sure you're getting 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.
Can you replace your own windows?
Although you can install your own windows, doing so requires a lot of time and experience with home improvement projects. Using a window replacement company can help ensure that the job is done properly and that you won't have to spend the time and effort to do it yourself.
How long does it typically take to install windows?
Each window takes about 30 minutes to install based 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.
How often should you replace windows?
Windows typically last around 20 to 30 years, but anytime you notice damage on your windows, it's a good time to have an expert take a look at them to determine if they need any repairs or replacements.
