How Installing Energy-Efficient Windows in Friendly Saves You Money

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

  • Save on energy bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of energy use in your home. Upgrading to energy-efficient windows can help lower that amount, which helps you save some money on your bills.
  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, especially if your home is on the older side.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
  • Reduce your carbon footprint: In Friendly, you can cut your indirect greenhouse gas emissions by about 249 pounds per year after you install energy-efficient windows.

Estimated Cost of Window Replacement in Friendly

Windows come in different shapes and sizes, so costs and services will differ considerably. Here are the typical costs and services that you can find from window installation companies.

How Much Do New Windows Cost?

On average, Friendly homeowners can anticipate their replacement window installations to range from $250 to $1,200. The average cost is at about $600. This is because the cost of window installations depend on several factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.

With windows, efficiency is one of the most important factors for most homeowners. High efficiency windows may cost more upfront, 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 Friendly homeowners $283+ each year after replacing single-pane windows.

Costs will also vary based on the material of your frame. Aluminum frames have the lowest price. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

In regard to window replacements, in general there are two types that your provider will offer: full-frame and pocket installations.

Full-frame installations entail replacing the total window, including the sill, trim and frame. You most likely need a full-frame installation when you want to change the style of your windows or your window has considerable deterioration. Because these installations are more involved, they will raise the overall cost. A pocket installation entails installing a new window without replacing the frame. This means instead of taking out the whole unit and reinstalling it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company will be able to advise you on the best type for your project. In Friendly, the choice will mostly be influenced by how much damage there is currently and the condition of your existing frames.

How We Choose the Best Window Installers in Friendly

In our hunt to make your home improvements easier and more eco-friendly in Friendly, EcoWatch evaluated dozens of companies before deciding on these. We’ve evaluated the top window installation companies in Friendly mainly 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

Because this is a guide for Friendly, we gave more points to companies that serve the city. There are certainly other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Friendly.

Work Quality

When selecting new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand you choose. We do give window installers higher marks 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 most customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including professionalism, quality of installation, quality of parts, warranty, cost and more.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like 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 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

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

Friendly, MD Window Replacement FAQs

How much does window installation cost?

The average cost of replacing a single window can range between $450 and $650. There are several factors that affect how much it costs, which include styles and sizes of windows, your property’s location, local labor costs, how energy-efficient the windows are, the number of windows and the materials used in designing the windows.

What are the most common kinds of replacement windows?

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

When do I have to use a window installation company?

Unless you have home repair skills and have the tools needed to replace your own windows, we recommend hiring a professional installer. The process of installing windows is complicated and can take anywhere from four to six hours for one window. Although it’s tempting to try to save some money by doing it yourself, hiring a professional is a faster, more efficient and much safer option.

What time of year should I replace my windows?

Although you can install windows any time of year, warmer weather is usually better for replacing windows. Additionally, it shouldn’t be raining, as rain can make the installation harder.

How do you know it’s time to replace your windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to operate, they may need to be replaced.
