How Installing Energy-Efficient Windows in Stanford Saves You Money
By switching to energy-efficient windows, you can benefit in several ways, including:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: When you have an older home, your windows could also be outdated or damaged.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.
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Stanford, that's about 117 pounds per year on average.
- Save on power bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of energy use in your home. Switching to energy-efficient windows can help decrease that number, which helps you save some money on your bills.
Estimated Cost of Window Replacement in Stanford
Windows come in various shapes, styles and purposes, so costs and services will differ remarkably based on several factors. Below, we describe the typical cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
Though the average of installing a single window is around $600, it can range from $200 to $1,200. These figures are based on specific characteristics of your installation, such as size, number of windows, the location of your home, type, material and more.
With windows, efficiency is one of the most important factors for most homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — especially if you live in a hot climate — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Stanford homeowners $624+ each year after replacing single-pane windows.
Costs will also vary depending on the material you pick for your window frames. Aluminum frames are the least expensive. They're sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
The first step when planning a window installation is to figure out whether you should get a full-frame or pocket installation.
A full-frame installation is a replacement of the total window. This service involves removing the old window, the sill, and the exterior and interior trim. It also involves other materials, including insulation and drip edges, which raise the total cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. A pocket installation entails replacing a window without removing the whole frame, which is usually less expensive than a full-frame installation.
If you're still debating which type of installation you should get, you can ask your installer and get their recommendation. The decision mostly depends on the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in Stanford
In our hunt to make your home improvements easier and more eco-friendly in Stanford, the EcoWatch team landed on the above companies as the top window installation companies in the city. We've evaluated the best window replacement companies in Stanford 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 energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for Stanford, we gave more points to companies that provide services to the city. There are certainly other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Stanford.
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 included on this list 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
We analyzed trends in recent customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including warranty, quality of parts, cost, quality of installation, professionalism and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. That's why window installation companies that have lengthy warranties for products, parts and labor 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 installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Stanford, CA Window Replacement FAQs
How much does a window install cost?
The national average cost of replacing a single window is around $600 but can range between $200 and $1,200, depending on a variety of factors. The price is generally influenced by the type and material of the window, the location of your property and the size of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
Which kind of window is the best?
A window's energy efficiency depends on several 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 and are certified by the U.S. Department of Energy.
When do I have to use a window installation company?
Unless you have experience with home improvement projects and have the tools needed to replace your own windows, we recommend hiring a professional. The process of installing windows is complicated and can take anywhere from four to six hours for a single 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 option.
What time of year is the best time to replace my windows?
Even though you can install windows any time of year, warmer weather is typically better for replacing windows. Additionally, the weather should be dry, as rain can make the installation more difficult.
