How Installing Energy-Efficient Windows in Los Altos Hills Saves You Money

Upgrading to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here's more information on how upgrading your windows could benefit you:

  • Save money on power bills: After you install energy-efficient windows, you can see a reduction in your bills by about 12% since you'll use less energy to heat or cool your home.
  • Decrease your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Los Altos Hills, that's about 117 pounds per year on average.
  • Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if you have an older home.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in Los Altos Hills

Windows come in various shapes and sizes, so costs and services will vary greatly. Here are the typical costs and services that you can find from window installers.

How Much Do New Windows Cost?

Generally, Los Altos Hills homeowners can expect their replacement window installations to range from $250 to $1,200. The average cost is at about $600. This is because window installations depend on several factors specific to your home, including the size, material and number of windows you need to install, as well as where your property is located.

With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Los Altos Hills homeowners $636+ per year after replacing single-pane windows.

Another factor that affects the total cost is the material of the frame you select. Aluminum frames are generally the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

The first question to ask yourself when planning to replace your windows is: Do you want a full-frame installation or a pocket installation?

Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has a great amount of damage. Full-frame installations are more comprehensive and will increase overall costs. A pocket installation entails replacing a window within the existing frame, which is generally cheaper than a full-frame installation.

Your window installation company will be able to recommend the best type for your project. In Los Altos Hills, the decision will mostly be influenced by how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Los Altos Hills

EcoWatch reviews differ from other reviews, as we assess these companies through a sustainability lens. We have assessed the top window replacement companies in Los Altos Hills primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installers that serve Los Altos Hills so you can find a quality window installation company near you.

Work Quality

We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer 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

We analyzed trends in recent online reviews to determine the companies with the most customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including professionalism, warranty, quality of parts, quality of installation, cost and more.

Cost

This one is a give-and-take: similar to other services, cheap window installers are not going to 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 previously, windows are a substantial investment, so you'll want to be certain that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Los Altos Hills, CA Window Replacement FAQs

How much should window installation cost?

The national average cost to replace a single window is around $600 but can range from $200 to $1,200, based on several factors. The price is usually influenced by the location of your property, the type and material of the window and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

What are the different kinds of windows?

There are several different kinds of windows you can get for your home, including double-hung and single-hung windows, transom windows, awning windows, bay windows, casement windows, slider windows and picture windows.

When do I need to use a window installation company?

Unless you're handy and have all the tools you need to replace your own windows, we recommend hiring a professional installer. The window installation process is complicated and can take anywhere from four to six hours for a single window. Although it's tempting to try to save money by doing it yourself, hiring a company is a faster, more efficient and safer option.

How long does window installation generally take?

Because a window takes about 30 minutes to install, about 16 windows can be installed during a typical 8-hour work day.

Should I replace all my windows at the same time?

If you're upgrading your windows to get more efficient windows, replacing all of your windows at once is the only way to see a noticeable difference. On the other hand, if you have just a few windows that are broken or drafty, you can replace just those.
