How Installing Energy-Efficient Windows in Holtsville Saves You Money

There are several perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the change are the following:

  • Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Save on power bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of household energy use. Replacing your windows with energy-efficient models can help reduce that number, therefore saving you about 12% more on your bills.
  • Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
  • Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.

Estimated Cost of Window Replacement in Holtsville

Each window replacement company offers various services and has different price points depending on a few factors.

How Much Do New Windows Cost?

According to our research, the typical cost to replace a single window is about $600. However, window replacement costs can range from $200 to $1,200 for each window. How much it will cost is based on several factors, like material, size, type, number of windows, the location of your home and more.

With windows, efficiency is one of the most important factors for most 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 give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Holtsville homeowners $215+ per year after replacing single-pane windows.

How much your window installation costs will also vary depending on the kind of window material you choose for the frames. Wood windows are generally the most expensive, though it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

The first question to ask yourself when getting new windows is: Do you need a full-frame installation or a pocket installation?

A full-frame installation replaces the entire window, such as the windowsill, frame, trim and the window panes. As this kind of installation requires more time, it will cost more than a pocket installation. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.

If you’re still debating which kind of installation to get, you can consult with your installer and get their advice. The choice mostly depends on how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Holtsville

The EcoWatch Reviews team differs from other reviewers, as we look at these companies through a sustainability lens. We’ve assessed the best window installers in Holtsville primarily based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve Holtsville so you can find a quality window installation company near you.

Work Quality

We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each company featured on this list to ensure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the most consistent 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 most other categories, including quality of parts, quality of installation, cost, warranty, professionalism and more.

Cost

This one is a give-and-take: as with most services, cheap window companies won’t always provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that offer a spectrum of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed, windows are a significant investment, so you’ll want to be certain that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Holtsville, NY Window Replacement FAQs

What is the typical cost to install windows?

The average cost of installing a single window ranges from $450 to $650. There are many factors that affect the price, such as the number of windows, the materials used in designing the windows, your property’s location, styles and sizes of windows, how energy-efficient the windows are and local labor costs.

What are the most common types of replacement windows?

There are various types of windows you can get for your home, including bay windows, transom windows, slider windows, picture windows, casement windows, double-hung and single-hung windows and awning windows.

What do window installers do?

Window installation professionals go to your home to remove your old windows and replace them with new ones. Some companies install products made by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is complete.

When is the best time of year to replace windows?

Replacement windows can be installed any time of the year, 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 your house, so the temperature outside isn’t necessarily a big factor. What’s more important than the temperature is that the weather should be dry.
