How Installing Energy-Efficient Windows in Fullerton Saves You Money

There are quite a few benefits of switching to energy-efficient windows. A few reasons you may want to consider making the change include the following:

• Reduce your carbon footprint: By using less energy after you switch to energy-efficient windows, you’ll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
• 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 Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
• Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
• Save money on power bills: Installing energy-efficient windows reduces your energy bills by about 12% because you use less energy.

Estimated Cost of Window Replacement in Fullerton

Windows come in varying purposes, styles and shapes, so costs and services will differ greatly depending on several factors. Below, we go over the average cost and services that you can get from window installers.

How Much Do New Windows Cost?

Although the typical cost to replace one window is around $600, it can range from $200 to $1,200. But costs vary remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door replacements, which have a higher price tag.

With windows, efficiency is the most important factor for many homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Fullerton homeowners $303+ each year after replacing single-pane windows.

The cost of your window installation will also vary depending on the type of window material you choose for the frames. Wood windows are generally 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 more efficient.

What Services do Window Installers Offer?

The first question to ask yourself when planning on installing new windows is: Do you want a full-frame installation or a pocket installation?

A full-frame installation is a replacement of the total window. It involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves other materials, including insulation and drip edges, which increase the overall cost of the project. It’s also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

Your window installation company should be able to help you decide what’s best for your needs. In Fullerton, the decision will mostly depend 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 Fullerton

In our search to make your home improvements easier and more eco-friendly in Fullerton, the EcoWatch team examined many companies before deciding on these. We’ve assessed the top window installation companies in Fullerton mostly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows have been shown to lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for Fullerton, we only included companies that cover the city. There are certainly other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Fullerton.

Work Quality

We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company on this list to ensure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have nice feedback about their service from a certain window installation company, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: as with other services, cheap window installation companies may not provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed, windows are a serious investment, so you’ll want to be certain that investment is protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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