How Installing Energy-Efficient Windows in Novato Saves You Money

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

• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, particularly if your home is on the older side.
• Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
• Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of household energy use. Installing energy-efficient windows can help reduce that number, which helps you save more on your bills.

Estimated Cost of Window Replacement in Novato

Let’s take a look at the cost of updating your windows and the types of services you may need for your home.

How Much Do New Windows Cost?

Typically, Novato homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at approximately $600. But prices vary considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations, which will add extra costs to your project.

It’s also worth noting that energy-efficient windows will almost always cost more initially, but Energy Star estimates that upgrading the windows on your Novato home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you’ll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

How much your window installation costs will also vary depending on the type of material you choose for the frames. Wood windows are usually the most expensive, but it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

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

Full-frame installations involve replacing the complete window, including the trim, sill and frame. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable damage or rot. These installations are more involved and will increase the total cost. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.

If you’re hiring a reputable window installation company, your company can advise you on the best type for your project. In Novato, the choice will mostly be based on the efficiency of your home and how old your existing frames are.

This one is a give-and-take: similar to most 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 wide range 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 protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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