How Installing Energy-Efficient Windows in Oakley Saves You Money

When you switch to energy-efficient windows, you may see some perks, including:

  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if you have an older home.
  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Save on power bills: Because energy-efficient windows decrease the amount of energy needed to heat or cool your home, they can help you save about $579 annually on your energy bills in Oakley.
  • Decrease your carbon footprint: In Oakley, you can reduce your indirect greenhouse gas emissions by about 117 pounds per year once you upgrade to energy-efficient windows.

Estimated Cost of Window Replacement in Oakley

When researching window installation, each company offers different services and prices. Let’s take a look at some average costs and services.

How Much Do New Windows Cost?

Generally, Oakley homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost is at about $600. This is because the cost of window installations are based on several factors specific to your home, like the size, material and number of windows you need to replace, as well as the location of your property.

It’s important to note that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Oakley homeowners $579+ a year when replacing single-pane windows.

Costs will also vary based on the material of your frame. Aluminum frames have the lowest price. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made from 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 offer decent insulation for your home.

What Services do Window Installers Offer?

In general, there are two kinds of window replacement services companies offer: full-frame and pocket installations.

A full-frame installation replaces the entire window, such as the sill, frame, trim and the window panes. As this type of installation requires more time, it will cost more than a pocket installation. A pocket installation involves replacing a window within the existing frame, which is usually less expensive than a full-frame installation.

If you’re still debating which kind of installation you should get, you can consult with your provider and get their recommendation. The decision mostly is influenced by how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Oakley

In our hunt to make your home improvements easier and more eco-friendly in Oakley, the EcoWatch Reviews team assessed dozens of companies before deciding on these. We have assessed the best window installation companies in Oakley primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to cut 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 installation companies that serve a wide variety of states and cities so you can find the right window installation company near you.

Work Quality

We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company 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

Customer feedback is another very important review factor. If most customers don’t have nice things to say about their service from a certain installer, it won’t be featured on EcoWatch.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs as low as 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 hefty investment, so you’ll want to be certain that investment is protected. Window installation companies that offer 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 been in the industry for a while. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Oakley, CA Window Replacement FAQs

What is the average cost to replace windows?

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

What are the most common types of replacement windows?

The most common types of windows for homes are slider windows, bay windows, transom windows, casement windows, awning windows, picture windows and double-hung and single-hung windows.

What do window installers do?

Window installers visit your property to remove your old windows and replace them with new ones. Some providers install products sold by other companies, whereas others install their own windows. The installer will also clean up after the installation.

What time of year should I replace my windows?

Replacement windows can be installed during any season, but autumn might be best. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into the house, so the temperature outside isn’t necessarily a big factor. What’s more important than the temperature is that the weather should be dry.

How often should you replace your windows?

Windows usually last around 20 to 30 years, but anytime you notice damage on your windows, it’s a good time to have an expert take a look at them to determine if they need any repairs or replacements.
