How Installing Energy-Efficient Windows in St John Saves You Money

Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to take the plunge and make the switch:

  • 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.
  • Reduce your carbon footprint: By using less energy once upgrading to energy-efficient windows, you'll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Save money on electricity bills: Installing energy-efficient windows reduces your energy bills by about 12% because you use less energy.

Estimated Cost of Window Replacement in St John

When considering window installation, each company provides different services and costs. Let's go over some average costs and services.

How Much Do New Windows Cost?

The average cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. These estimates vary based on the specifics of your installation, like size, material, the location of your home, type, number of windows and more.

With windows, efficiency is one of the most important factors for most homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — especially 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 St John homeowners $376+ each year after replacing single-pane windows.

Something else that influences the overall cost is the material of the frame you choose. Aluminum frames are usually the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

When it comes to window replacements, there are generally two types that your provider will offer: full-frame and pocket installations.

A full-frame installation is a replacement of the full window. This service involves removing the old window, the sill, and the exterior and interior trim. It also involves extra materials, like insulation and drip edges, which raise the total cost of the project. It's also worth noting that it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. A pocket installation entails replacing a window without removing the entire frame, which tends to be less expensive than a full-frame installation.

Your window installation company can help you decide which type of installation you should get.

How We Choose the Best Window Installers in St John

In our search to find the most reliable, eco-friendly window installers in St John, the EcoWatch team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we assessed window companies all across the state and assigned rankings based on the following methodology:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer included in our guide to make sure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including quality of installation, warranty, professionalism, cost, quality of parts and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers' prices, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

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

Years of Experience

Last but not least, we like to see companies that have been in the industry for a while. 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.

What time of year is a good time to replace my windows?

Replacement windows can be installed at any time, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into the home, so the temperature outside doesn't necessarily matter that much. What's most important is that the weather should be dry.

Should I replace all my windows at once?

If your windows are greater than 20 years old, you probably need to replace all of them. At that point, they are usually less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less time.
