August Window Cost Calculator

Calculate how much you can expect to pay for window installation and replacement in August, CA using our customized window cost calculator.

Estimated Window Cost:
161 homeowners have requested a free estimate in the last 3 days.

Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.

How Installing Energy-Efficient Windows in August 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 valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Decrease your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In August, that's about 117 pounds per year on average.
  • Save on electricity bills: Once you install energy-efficient windows, you can see a reduction in your bills by about 12% because you'll need less energy to heat or cool your home.
  • Protect your investment: If you have an older home, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.

Estimated Cost of Window Replacement in August

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

How Much Do New Windows Cost?

The average cost to install one window is about $600 but can range from $200 to $1,200. Costs will differ considerably depending on the number of windows you need, your location, the current condition of your home and the quality of your products. A lot of window companies also offer door installations and other add-ons like shutters, coating, baths and more. Additional services will increase overall project costs.

It's important to keep 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 certified energy-efficient windows can save August homeowners $690+ a year when replacing single-pane windows.

Another factor that influences the total cost is the material you choose for your frame. Aluminum frames are typically 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?

In general, there are two kinds of window replacement services you can get: full-frame and pocket installations.

Full-frame installations involve replacing the total window, including the frame, sill and trim. You most likely need a full-frame installation when you want to change the style of your windows or your window has considerable deterioration. Because full-frame installations are more involved, they will raise the overall cost. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won't cost as much, but you can't do this type of installment if you have any pre-existing rot or water damage.

If you're still trying to decide which kind of installation you should get, you can consult with your provider and get their advice. The choice mostly is influenced by how old the frames are and if there's any damage.

How We Choose the Best Window Installers in August

In our search to make your home improvements easier and more eco-friendly in August, EcoWatch assessed dozens of companies before settling on these. Along with energy efficiency, we evaluated each installer and ranked them based on the following methodology:

Service Area

Because this is a guide for August, we paid more attention to companies that provide services to the city. There are other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in August.

Work Quality

We're certain that you're looking for a company to do a great job installing windows. We've vetted each company in our guide to make sure its technicians are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have good things to say about their service from a certain window installation company, you won't see it 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 providers' prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

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 offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

August, CA Window Replacement FAQs

What is the average cost to replace windows in a home?

The typical cost to replace a single window can range between $450 and $650. There are many factors that affect the cost, such as how energy-efficient the windows are, your property's location, the materials used in designing the windows, local labor costs, the number of windows and styles and sizes of windows.

Which kind of window should I get?

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

Can I replace my own windows?

Although you can install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Hiring a professional can help guarantee that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.

Should I replace all my windows at once?

If you're upgrading your windows to get more efficient windows, replacing all of your windows together is the only way to see a noticeable difference. However, if you have just a few windows that are damaged or leaky, you can replace just those.
