How Installing Energy-Efficient Windows in Oakland Saves You Money

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

• Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
• Save on power bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Replacing your windows with energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
• Decrease your carbon footprint: In Oakland, you can reduce your indirect greenhouse gas emissions by about 117 pounds per year when you install energy-efficient windows.

Estimated Cost of Window Replacement in Oakland

Windows come in different shapes and sizes, so costs and services will vary remarkably. Here are the average costs and services that you can find from window installers.

How Much Do New Windows Cost?

According to our market research, the national average cost to replace a single window is about $600. However, window replacement costs can range from $200 to $1,200 a window. These estimates vary based on the specifics of your installation, including the location of your home, material, size, number of windows, type and more.

With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Oakland homeowners $531+ each year after replacing single-pane windows.

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 if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

The first step when planning an installation is to clarify whether you should get a full-frame or pocket installation.

A full-frame installation replaces the entire window, such as the sill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.

Your window installation company can recommend the best type for your project. In Oakland, the decision will mostly depend on how much damage there is currently and the condition of your existing frames.

How We Choose the Best Window Installers in Oakland

In our hunt to make your home improvements easier and more eco-friendly in Oakland, the EcoWatch team examined many companies before settling on these. We've decided to evaluate the best window installation companies in Oakland mainly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installers that serve Oakland so you can find the best window installation company near you.

Work Quality

When installing new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the type of window you opt for. 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

Customer feedback is another super important review factor. If most customers don't have good things to say about their experience with a certain company, it won't be featured on EcoWatch.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs low when 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 considerable investment, so you'll want to make sure 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

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