How Installing Energy-Efficient Windows in Marin City Saves You Money

There are several perks of switching to energy-efficient windows. Some reasons you may want to consider making the switch include the following:

• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Protect your investment: When you have an older home, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its value.
• Save money on energy bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, the switch can help you save around $635 annually on your energy bills in Marin City.
• Reduce your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Marin City, that's about 117 pounds per year on average.

Estimated Cost of Window Replacement in Marin City

Windows come in different shapes, purposes and styles, so costs and services will differ remarkably depending on your project. Below, we go over the typical cost and services that you'll find from window installation companies.

How Much Do New Windows Cost?

According to our research, the average cost of installing a single window is around $600. However, window installation costs can range from $200 to $1,200 a window. These figures vary depending on the specifics of your installation, such as the location of your home, number of windows, material, size, type and more.

Keep in mind that energy-efficient windows may have a higher price, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.

Another factor that influences the total cost is the material of the frame you select. Aluminum frames are generally the least pricey 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 as well and cost somewhere between the other two.

What Services do Window Installers Offer?

When considering window installations, there are typically two types that your installer will offer: full-frame and pocket installations.

Full-frame installations involve replacing the total window, including the sill, frame and trim. Full-frame installations are necessary when you want a new style or your window has noticeable damage or rot. Because full-frame installations are more involved, they will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are simpler and won't carry as large a bill, but you can't do this type of installment if you have any pre-existing rot or water damage.

Your window installation company will be able to help you understand what's best for your needs. In Marin City, the decision will mostly be based on how old your windows are and if there's any damage. Wood can decay if not maintained properly over the years, so it's good to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Marin City

In our hunt to find the most reliable, eco-friendly window installers in Marin City, EcoWatch examined dozens of companies before landing on these. Along with energy efficiency, we evaluated each installer and ranked them using the following methodology:

Service Area

Because this is a guide for Marin City, we only included companies that cover the city. There are certainly reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Marin City.

Work Quality

When picking new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the type of window you choose. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including professionalism, quality of parts, quality of installation, warranty, cost and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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