How Installing Energy-Efficient Windows in Wake Forest Saves You Money

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

  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Wake Forest, that’s about 345 pounds per year on average.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
  • Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Upgrading to energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Wake Forest

When researching window installation, each company provides varying services and prices. Let’s take a look at some typical costs and services.

How Much Do New Windows Cost?

The average cost to replace one window is about $600 but can range from $200 to $1,200. This is because the cost of window installations are based on several factors specific to your home, like 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 many homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Wake Forest homeowners $358+ a year after replacing single-pane windows.

Something else that influences the total cost is the material of the frame you choose. Aluminum frames are generally the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most 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?

Generally, there are two types of window replacement services you can get: 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 noticeable rot. Because these installations are more involved, they will raise the overall cost. Pocket installations are simpler and won’t cost as much, as they involve merely replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.

If you’re hiring a reputable window installation company, your company will be able to recommend the best type for your project. In Wake Forest, the choice will mostly be based on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Wake Forest

EcoWatch is different from most reviewers since we assess these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Wake Forest and assigned rankings based on the following methodology:

Service Area

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

Work Quality

We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company featured in our guide to ensure its contractors are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

Customer Reviews

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

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important to many homeowners. That’s why window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Wake Forest, NC Window Replacement FAQs

What is the average cost to replace windows?

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

What are the different types of windows?

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

What do window installers do?

Window installers go to your property to remove your old windows and replace them with new ones. Some providers install products sold by other companies, whereas others install their own windows. The installer will also clean up after the installation.

Should I replace my windows all at the same time?

If you’re upgrading your windows because of energy-efficiency, replacing all the windows at the same time is the only way to gain that benefit. However, if you have only one or two windows that are broken or leaky, you can replace just those.
