How Installing Energy-Efficient Windows in Newcastle 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: 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 Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
• Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
• Decrease your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by 271 pounds per year on average.
• Save on power bills: Because energy-efficient windows decrease the amount of energy used to heat or cool your home, the switch can help you save around $366 annually on your energy bills in Newcastle.

Estimated Cost of Window Replacement in Newcastle

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

How Much Do New Windows Cost?

Generally, homeowners in Newcastle can anticipate that most replacement window installations will range from $250 to $1,200, with the average cost sitting at around $600. These amounts are based on the specifics of your installation, like size, the location of your home, material, type, number of windows and more.

With windows, efficiency is one of the most important factors for most homeowners. High efficiency windows may cost more initially, but by increasing the efficiency of your home — particularly during the winter — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Newcastle homeowners $366+ per year after replacing single-pane windows.

We advise getting free quotes from several window installers to find the one that works best for your budget.

What Services do Window Installers Offer?

Generally, there are two kinds of window replacement services you can get: full-frame and pocket installations.

A full-frame installation replaces the complete window, such as the windowsill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will be more expensive than a pocket installation. A pocket installation entails replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.

If you’re hiring a reputable window installation company, your company will be able to recommend the best type for your project. In Newcastle, the decision will mostly be based on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Newcastle

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

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve Newcastle 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 company on this list to make sure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don’t have positive feedback about their service from a certain installer, you won’t see it featured on EcoWatch.

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 gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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