How Installing Energy-Efficient Windows in Peru Saves You Money

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

• Protect your valuables: Many energy-efficient 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.
• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
• Save money on energy bills: Since energy-efficient windows reduce the amount of energy used to heat or cool your home, they can help you save about $308 annually on your energy bills in Peru.
• Decrease your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Peru, that’s about 642 pounds per year on average.

Estimated Cost of Window Replacement in Peru

When looking into window installation, each company offers varying services and prices. Let’s look at some typical costs and services.

How Much Do New Windows Cost?

Typically, homeowners in Peru can anticipate that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at around $600. How much it will cost varies based on several factors, including the location of your home, material, type, size, number of windows and more.

With windows, efficiency is one of the most important factors for many homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Peru homeowners $308+ each year after replacing single-pane windows.

What Services do Window Installers Offer?

The first thing to ask yourself when considering a window replacement is: Do you want a full-frame installation or a pocket installation?

A full-frame installation is a total window replacement. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, including insulation and drip edges, which increase 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 are on the simpler end and won’t cost as much because they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.

Your window installation company can help you choose which type of installation you need.

How We Choose the Best Window Installers in Peru

EcoWatch differs from most reviewers, as we assess these companies through a sustainability lens. We have reviewed the best window installers in Peru mostly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Since this is a guide for Peru, we paid more attention to companies that cover the city. There are other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Peru.

Work Quality

When choosing new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand of window you choose. 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

We analyzed trends in recent customer feedback to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including cost, warranty, quality of parts, professionalism, quality of installation and more.

Cost

This one is a give-and-take: as with most services, cheap window installers won’t always provide the most quality service. Still, we want to ensure we’re highlighting companies that offer a range 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 be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a proven track record in the industry. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
