That's bad news for both your bank account and the environment, but one of the best window installation companies can help with that.

We've compiled a list of the best installation companies to help you in your search, so you can not only take advantage of brand new windows, but also save money on your power bills.

How Installing Energy-Efficient Windows in Pleasanton Saves You Money

There are quite a few perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch are the following:

  • Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its real estate value.
  • Decrease your carbon footprint: In Pleasanton, you can cut your indirect greenhouse gas emissions by about 117 pounds per year once you install energy-efficient windows.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Save on energy bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Replacing your windows with energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Pleasanton

Windows come in varying purposes, shapes and styles, so costs and services will vary greatly based on several factors. Below, we describe the average cost and services that you'll find from window installers.

How Much Do New Windows Cost?

The national average cost to replace a single window is about $600 but can range from $200 to $1,200. But prices differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door replacements, which will add extra costs to your project.

It's important to bear in mind that windows with the best efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Pleasanton homeowners $531+ a year when replacing single-pane windows.

Costs will also vary depending on the material you choose for your window frames. Aluminum frames cost the least. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and provide 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 replaces the complete window, including the sill, frame, trim and the window panes. Because this type of installation is more involved, it will cost more than a pocket installation. Pocket installations are simpler and won't cost as much because they entail simply replacing the window within its existing frame. But if the frame has any damage, you may have to get a full-frame installation instead.

Your window installation company should be able to help you choose what's best for your needs. In Pleasanton, the decision will mostly be based on the age of your windows and if there's any damage. Wood can decay if not properly maintained over the years, so it's a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Pleasanton

EcoWatch reviews are different from most reviews because we examine these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and assigned rankings based on the following methodology:

Service Area

Because this is a guide for Pleasanton, we gave more points to companies that serve the city. There are certainly reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Pleasanton.

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 company on this list to ensure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don't have positive things to say 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 would like to keep costs low when possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed, windows are a substantial investment, so you'll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Pleasanton, CA Window Replacement FAQs

What is the typical cost to install windows in a home?

The national average cost to install one window is about $600 but can range from $200 to $1,200, based on a variety of factors. The price is generally influenced by the size of the window, the location of your property and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

Which kind of window should I get?

Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.

When do I have to use a window installation company?

You should hire a window installation professional whenever you need to replace your windows. Installing windows is a complex process that can be difficult and time-consuming, so it's best handled by the professionals.

How long does it take to install windows?

Since the average installation time is 30 minutes per window, around 16 windows can be installed in an 8-hour work day.

Should I replace all my windows at the same time?

If your windows are more than 20 years old, it's probably time to replace all of them. By that point, they are usually less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less time.
