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

Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to take the plunge and make the switch:

• Decrease your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Los Altos, that’s about 117 pounds per year on average.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
• Save money on power bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Switching to energy-efficient models can help decrease that number, therefore saving you about 12% more on your bills.
• Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if your home is on the older side.

Estimated Cost of Window Replacement in Los Altos

Each window installation company offers varying services and has varying prices depending on a few factors.

How Much Do New Windows Cost?

On average, homeowners in Los Altos can expect that most window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. This is due to the fact that window installations are based on several factors specific to your home, including the size, material and number of windows you need to install, as well as the location of your property.

With windows, efficiency is one of the most important factors for many 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 give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Los Altos homeowners $562+ each year after replacing single-pane windows.

Costs will also vary depending on the material you want for your window frames. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made with 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?

Generally, there are two kinds of window installation services you can get: full-frame and pocket installations.

A full-frame installation is a total window replacement. It involves removing the old window, the sill, and the exterior and interior trim. It can also involve extra 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 surrounding the window after a full-frame installation. A pocket installation means replacing a window without removing the entire frame, which is generally cheaper than a full-frame installation.

Your window installer should be able to help you decide which type of installation you need.

Service Area

Since this is a guide for Los Altos, we only included companies that provide services to the city. There are other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Los Altos.

Work Quality

We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer included on this list to ensure its contractors are well-qualified and that the company has gotten lots 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 consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including warranty, cost, professionalism, quality of parts, quality of installation and more.

Cost

This one is a give-and-take: as with other services, cheap window installation companies won’t always provide the highest quality service. Still, we want to make sure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Los Altos’s climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Los Altos window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
