How Installing Energy-Efficient Windows in Modesto Saves You Money
There are quite a few benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the change include the following:
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if you have an older home.
- 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.
- Better temperature control in your home: Energy-efficient windows can decrease how hard your heating system needs to work to heat your home.
- Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 117 pounds.
Estimated Cost of Window Replacement in Modesto
Windows come in varying shapes and sizes, so costs and services will vary tremendously. Here are the average costs and services that you can find from window installation companies.
How Much Do New Windows Cost?
The average cost to install a single window is about $600 but can range anywhere from $200 to $1,200. How much it will cost you varies depending on several factors, including size, number of windows, material, type, the location of your home and more.
Whether or not you choose energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $594 a year on your energy bills in Modesto.
How much your window installation costs will also vary based on the type of window material you choose for the frames. Wood windows are usually the most expensive, but it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
The first thing to ask yourself when planning on installing new windows is: Do you need a full-frame installation or a pocket installation?
A full-frame installation is a replacement of the full window. It involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, such as insulation and drip edges, which increase the overall cost of the project. It's also worth noting that you may have to touch up the paint around the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.
Your window replacement company should be able to help you figure out what's best for your needs. In Modesto, the decision will mostly depend on how old your windows are and if there's any moisture damage. Wood can decay if 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 Modesto
EcoWatch differs from most reviewers, as we examine these companies through a sustainability lens. We have decided to assess the top window installation companies in Modesto mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve the Modesto area so you can find the best window installation company near you.
Work Quality
When it comes to new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand of window you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don't have nice feedback about their service from a certain installer, you won't see it featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a significant investment, so you'll want to be certain that investment is protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for a while. 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.
Modesto, CA Window Replacement FAQs
What is the average cost to install windows?
The national average cost to install one window is around $600 but can range from $200 to $1,200, based on a few different 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 initially but can save you hundreds of dollars a year in energy bills.
What are the different types of windows?
The most common kinds of windows for homes are transom windows, casement windows, slider windows, double-hung and single-hung windows, awning windows, bay windows and picture windows.
Can I replace my own windows?
Even though you can install your own windows, doing so is time-consuming and requires a lot of handiness. Hiring a professional 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 generally take to install windows?
Each window takes about 30 minutes to install based on the kind of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
When is the best time of year to replace windows?
Although you can install windows any time of year, warmer weather is usually better for installing replacement windows. Additionally, it shouldn't be raining, because rain can make the installation more difficult.
