How Installing Energy-Efficient Windows in Largo Saves You Money

There are quite a few benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch are the following:

  • Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 249 pounds per year on average.
  • Protect your investment: If you have an older home, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.
  • Save on power bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of residential energy use. Upgrading to energy-efficient windows can help decrease that number, which helps you save more on your bills.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Largo

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

How Much Do New Windows Cost?

According to our research, the average cost of installing a single window is around $600. However, window replacement costs can range from $200 to $1,200 per window. This is because of the fact that window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as the location of your property.

With windows, efficiency is one of the most important factors for most homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Largo homeowners $283+ per year after replacing single-pane windows.

We recommend getting free quotes from multiple window companies to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

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

A full-frame installation replaces the entire window, including the sill, frame, trim and the window panes. Because this type of installation requires more time, it will be more expensive than a pocket installation. A pocket installation involves replacing a window without replacing the frame. So, instead of removing the whole unit and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you’re still debating which type of installation you need, you can consult with your installer and get their recommendation. The decision mostly depends on how old the frames are and if there’s any damage present.

How We Choose the Best Window Installers in Largo

EcoWatch reviews differ from most reviews because we’re examining these companies through a sustainability lens. Along with energy efficiency, we reviewed window companies all across the state and assigned rankings based on the following methodology:

Service Area

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

Work Quality

When it comes to new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the type of window you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent customer feedback to determine the companies with the most customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including cost, quality of installation, warranty, quality of parts, professionalism 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 previously, windows are a considerable 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

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

Largo, MD Window Replacement FAQs

How much should window installation cost?

The typical cost to replace a single window ranges from $450 to $650. There are several factors that affect how much it costs, including local labor costs, the materials used in designing the windows, the number of windows, how energy-efficient the windows are, your property’s location and styles and sizes of windows.

What are the kinds of windows?

The most common types of windows for homes are picture windows, bay windows, slider windows, double-hung and single-hung windows, transom windows, awning windows and casement windows.

What do window installers do?

Window installers will do the entire process — from replacing old windows with new ones to cleaning up after the windows have been put in place. Additionally, a lot of companies offer window manufacturing, customization and repairs.

When is it time to replace your windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Other than that, if your windows have any damage on them, or they have become difficult to open or close, they may be in need of replacement.

Should I replace my windows all at once?

If you want to get more efficient windows and save money on your energy bills, replacing all of your windows at once is the only way to gain that benefit. On the other hand, if you have just one or two windows that are damaged or leaky, you can replace just those.
