How Installing Energy-Efficient Windows in Alum Rock Saves You Money
Energy-efficient windows can offer benefits in several ways. Here are some reasons you may want to think about making the switch:
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Reduce your carbon footprint: By using less energy once switching to energy-efficient windows, you'll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Save money on energy 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 amount, which helps you save more on your bills.
Estimated Cost of Window Replacement in Alum Rock
Let's take a look at the cost of installing new windows and the types of services offered by installers.
How Much Do New Windows Cost?
Typically, homeowners in Alum Rock can anticipate that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. Costs will vary considerably depending on the quality of your products, your location, the current condition of your home and the number of windows you need. A lot of window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. These extra services will increase overall project costs.
With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more initially, 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 Alum Rock homeowners $562+ a year after replacing single-pane windows.
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?
The first step of a window replacement is to think about whether you need a full-frame or pocket installation.
A full-frame installation is a replacement of the total window. It involves removing the old window, the sill, and the exterior and interior trim. It can also involve other materials, including insulation and drip edges, which increase the overall 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 replacing the frame. So, instead of tearing out the whole unit and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company will be able to advise you on the best type for your project. In Alum Rock, the choice will mostly be based on the efficiency of your home and the age of your existing frames.

How We Choose the Best Window Installers in Alum Rock
In our hunt to make your home improvements easier and more eco-friendly in Alum Rock, the EcoWatch team evaluated many companies before landing on these. We have decided to evaluate the best window installers in Alum Rock primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can reduce your power 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 the right window installation company near you.
Work Quality
When picking 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 give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including warranty, cost, quality of installation, quality of parts, professionalism and more.
Cost
This one is a give-and-take: similar to other services, cheap window companies won't always provide the highest quality service. Still, we want to ensure we're highlighting companies that offer a range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. That's why window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Alum Rock's climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Alum Rock window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Alum Rock, CA Window Replacement FAQs
How much should window installation cost?
The typical cost of installing a single window can range between $450 and $650. There are many factors that affect how much it costs, such as your property's location, styles and sizes of windows, the number of windows, how energy-efficient the windows are, local labor costs and the materials used in designing the windows.
Which kind of window is the best?
A window's energy efficiency depends on a number of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.
Can I install my own windows?
Even though it is possible to install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Hiring a professional can help ensure that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.
How long does it generally take to install windows?
Since the average installation time of a window is 30 minutes, about 16 windows can be installed during an 8-hour work day.
Should I replace all my windows at once?
If you want to get more efficient windows and save money on energy costs, replacing all of your windows together is the only way to gain that benefit. However, if you have only a few windows that are broken or leaky, you can replace just those.
