How Installing Energy-Efficient Windows in Antioch Saves You Money

Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to think about making the switch:

• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, especially if you have an older home.
• Save money on electricity bills: Because energy-efficient windows lower the amount of energy used to heat or cool your home, they can help you save about $579 annually on your energy bills in Antioch.
• Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can reduce your carbon footprint by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Antioch

Windows come in different styles, purposes and shapes, so costs and services will differ remarkably based on your project. Below, we detail the typical cost and services that you’ll find from window installers.

How Much Do New Windows Cost?

Typically, Antioch homeowners can expect their window installations to range from $250 to $1,200. The most common installations sit at around $600. How much it will cost depends on several factors, like the location of your home, material, type, size, number of windows and more.

It’s also worth keeping in mind that energy-efficient windows will usually cost more upfront, but Energy Star estimates that upgrading the windows on your Antioch home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

How much your window installation costs will also vary based on the type of window material you choose for the frames. Wood windows are typically the most expensive, though 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 shown to be more efficient.

What Services do Window Installers Offer?

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

A full-frame installation is a replacement of the full window. It involves taking out the old window, the sill, and the exterior and interior trim. It also involves additional materials, including insulation and drip edges, which raise the overall cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. 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 kind of installment if you have any pre-existing rot or water damage.

If you’re still trying to decide which type of installation to get, you can talk to your installer and get their advice. The choice mostly is influenced by the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Antioch

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

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

When it comes to new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the type of window you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent online reviews to find the companies with the most customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including quality of installation, professionalism, cost, warranty, quality of parts and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers want 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, windows are a significant investment, so you’ll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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