How Installing Energy-Efficient Windows in Sussex Saves You Money

By switching to energy-efficient windows, you can take advantage of several benefits, including:

• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
• Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Sussex, that’s about 497 pounds per year on average.
• Save money on power bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of energy use in your home. Switching to energy-efficient windows can help decrease that number, which helps you save some money on your bills.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Sussex

Windows come in various shapes and sizes, so costs and services will differ remarkably. Here are the average costs and services that you’ll find from the average window installation company.

How Much Do New Windows Cost?

The average cost to install one window is about $600 but can range anywhere from $200 to $1,200. Costs will differ significantly depending on your location, the number of windows you need, the current condition of your home and the quality of your products. A lot of window companies also offer door installations and other add-ons like coating, shutters, baths and more. Additional services will increase overall project costs.

With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more initially, but by increasing the efficiency of your home — especially during the winter — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Sussex homeowners $483+ each year after replacing single-pane windows.

Another factor that affects the total cost is the material you choose for your frame. Aluminum frames are typically the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

There are generally two kinds of window installation services: full-frame and pocket installations.

Full-frame installations are necessary when you want to change the style of your windows or your window has significant deterioration. With this service, your installers will replace the whole window, including the frame, sill and trim. A pocket installation involves replacing a window within the existing frame. This means instead of tearing out the whole unit and rebuilding it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window replacement company should be able to help you choose what’s best for your needs. In Sussex, the decision will mostly be based on the age of your windows and if there’s any moisture damage. Wood can decay if not maintained properly over the years, so it’s good to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Sussex

The EcoWatch Reviews team is different from other reviewers because we examine these companies through a sustainability lens. We’ve reviewed the top window installation companies in Sussex mainly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve Sussex so you can find the best window installation company near you.

Work Quality

When picking new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand you choose. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another very important review factor. If most customers don’t have positive things to say about their experience with a certain company, it won’t be featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers’ prices, 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. For that reason, window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a good track record in the industry. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
