How Installing Energy-Efficient Windows in San Juan Saves You Money

By upgrading to energy-efficient windows, you can benefit in several ways, such as:

• Decrease your carbon footprint: By using less energy after you switch to energy-efficient windows, you’ll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Save money on energy bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of household energy use. Upgrading to energy-efficient windows can help lower that number, which helps you save more on your bills.
• Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.
• Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in San Juan

Windows come in all shapes and sizes, so costs and services will vary greatly. Here are the average costs and services that you’ll find from window installers.

How Much Do New Windows Cost?

Typically, San Juan homeowners can expect their replacement window installations to range from $250 to $1,200. The average cost is at approximately $600. Costs will differ considerably depending on the quality of your products, the current condition of your home, your location and the number of windows you need. Many window companies also offer replacement door installations and other add-ons like baths, shutters, coating and more. These extra services will increase your overall project costs.

It’s also worth keeping in mind that energy-efficient windows will typically cost more upfront, but Energy Star predicts that upgrading the windows on your San Juan home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you’ll save by switching 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 depending on the type of window material you choose for the frames. Wood windows are typically the most expensive, although it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

The first step when planning a window replacement is to clarify whether you need a full-frame or pocket installation.

Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has significant deterioration. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you’re hiring a reputable window installation company, your company can advise you on the best type for your project. In San Juan, the decision will mostly be influenced by how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in San Juan

The EcoWatch Reviews team differs from most reviewers, as we evaluate these companies through a sustainability lens. We have assessed the top window replacement companies in San Juan mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

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

Work Quality

When it comes to new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand you opt for. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

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

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers’ prices, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

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

Years of Experience

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