20 Best Window Companies in Rosemont, CA (2025 Reviews)

How Installing Energy-Efficient Windows in Rosemont Saves You Money

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

• Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can reduce your carbon footprint by about 12%, according to Energy Star.
• Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.
• Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, especially if you have an older home.
• Save on electricity bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of energy use in your home. Switching to energy-efficient windows can help reduce that amount, which helps you save some money on your bills.

Estimated Cost of Window Replacement in Rosemont

Windows come in all shapes and sizes, so costs and services will vary greatly. Here are the typical costs and services that you can find from the average window installation company.

How Much Do New Windows Cost?

Typically, homeowners in Rosemont can expect that most window installations will cost between $250 and $1,200, with the average cost sitting at around $600. But costs differ 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 will make your project cost more.

With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Rosemont homeowners $688+ each year after replacing single-pane windows.

Something else that influences the total cost is the material of the frame you pick. Aluminum frames are usually the least pricey and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

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

A full-frame installation replaces the complete window, such as the windowsill, frame, trim and the window panes. Because this kind of installation requires more time, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the old 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.

Your window replacement company should be able to help you figure out what’s best for your needs. In Rosemont, the decision will mostly depend on the age of your windows and if there’s any damage. Wood can decay if not properly maintained 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 Rosemont

EcoWatch reviews are different from other reviews since we look at these companies through a sustainability lens. We’ve decided to evaluate the top window installers in Rosemont mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to lower 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 the Rosemont area so you can find the right window installation company near you.

Work Quality

We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each company featured on this list to make sure its contractors are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have nice things to say about their experience with a certain window installation company, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: as with most services, cheap window installers may not provide the most quality service. Still, 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 previously, windows are a sizable investment, so you’ll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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