How Installing Energy-Efficient Windows in Oceanside Saves You Money

By upgrading to energy-efficient windows, you and your family can enjoy several benefits, such as:

• 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 harmful UV rays, preventing fading of your furniture, carpet and other valuables.
• Save on energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of energy use in your home. Installing energy-efficient windows can help lower that number, which helps you save $283 a year on your bills.
• Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
• Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Oceanside, that’s about 307 pounds per year on average.

Estimated Cost of Window Replacement in Oceanside

Windows come in various shapes and sizes, so costs and services will differ considerably. Here are the typical costs and the primary services that you’ll find from window installation companies.

How Much Do New Windows Cost?

According to our market research, the typical cost of replacing a single window is about $600. However, window replacement costs can range from $200 to $1,200 for each window. How much it will cost depends on several factors, including the location of your home, number of windows, size, type, material and more.

Bear in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 per year when replacing single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.

Costs will also vary based on the material you choose for your window frames. Aluminum frames cost the least. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

The first thing to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?

Full-frame installations involve replacing the complete window, including the sill, trim and frame. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable rot. These installations are more involved and will increase overall costs. A pocket installation means replacing a window without taking out the whole frame, which tends to be cheaper than a full-frame installation.

Your window installer should be able to help you figure out which type of installation you need.

How We Choose the Best Window Installers in Oceanside

EcoWatch reviews differ from most reviews because we assess these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and ranked them based on the following methodology:

Service Area

Because this is a guide for Oceanside, we gave more points to companies that cover the city. There are certainly reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Oceanside.

Work Quality

When choosing new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand of window you get. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends 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 reflects the quality of services across nearly every category, including quality of installation, cost, professionalism, quality of parts, warranty and more.

Cost

This one is a give-and-take: similar to other services, cheap window companies are not going to provide the most quality service. Still, we want to make sure we’re highlighting companies that provide a range of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important. That’s why window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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