How Installing Energy-Efficient Windows in Delano Saves You Money
By switching to energy-efficient windows, you can take advantage of several benefits, such as:
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, particularly if you have an older home.
- 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 due to their ability to filter out damaging UV rays.
- Save on energy bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Replacing your windows with energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Delano, that’s about 117 pounds per year on average.
Estimated Cost of Window Replacement in Delano
Windows come in various styles, purposes and shapes, so costs and services will vary greatly based on your project. Below, we detail the average cost and services that you can get from window installers.
How Much Do New Windows Cost?
On average, homeowners in Delano can expect that most replacement window installations will range from $250 to $1,200, with the average cost at about $600. This is because window installations depend on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as where your property is located.
Bear in mind that energy-efficient windows may come at a higher price point, but Energy Star estimates the upgrade will save you between $101 and $583 a year when installing single-pane windows and between $27 and $197 per year when you install double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.
We advise getting free quotes from several window companies to find the one that works best for you.
What Services do Window Installers Offer?
The first step when considering a replacement is to decide whether you need a full-frame or pocket installation.
Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has a great amount of damage. Full-frame installations are more involved and will increase overall costs. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you will likely need a full-frame installation instead.
Your window replacement company will be able to help you figure out what’s best for your needs. In Delano, the decision will mostly depend on how old your home is and if there’s any moisture damage. Wood can decay if it’s not properly maintained over the years, so it’s good to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Delano
In our search to find the most reliable, eco-friendly window installers in Delano, EcoWatch evaluated many companies before deciding on these. We have decided to assess the top window installation companies in Delano mainly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers that serve Delano so you can find the right window installation company near you.
Work Quality
We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each company on this list to make sure its contractors are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don’t have nice feedback about their experience with a certain installer, it won’t be featured on EcoWatch.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a substantial investment, so you’ll want to make sure 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
Lastly, we like to see companies that have a good track record in the industry. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Delano, CA Window Replacement FAQs
What is the average cost to install new windows in a home?
The national average cost of replacing a single window is around $600 but can range between $200 and $1,200, depending on several factors. The price is often 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 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?
A window’s energy efficiency depends on a variety of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.
Can I replace my own windows?
While it is possible to install your own windows, doing so is time-consuming and requires a lot of handiness. Using a window replacement company can help guarantee that the job is done properly and that you won’t have to spend the time and effort to do it yourself.
How often should you replace your windows?
Windows generally last 20 to 30 years, but anytime you notice damage on your windows, it’s a good time to have them checked by an expert to determine if they are in need of a repair or replacement.
