How Installing Energy-Efficient Windows in Denville Saves You Money

By switching to energy-efficient windows, you can benefit in several ways, such as:

• Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
• Save money on power bills: Because energy-efficient windows reduce how much energy you need to heat or cool your home, the switch can help you save about $287 annually on your energy bills in Denville.
• More efficient energy use in your household: Because the winters can get very cold in Denville, homeowners often rely on their heater during that time. Energy-efficient windows cut back on the amount of heat that is lost through your windows, which makes it easier to keep your house warm.

Estimated Cost of Window Replacement in Denville

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

How Much Do New Windows Cost?

Generally, Denville homeowners can anticipate their replacement window installations to range from $250 to $1,200. The most common installations sit at approximately $600. Costs will vary considerably based on the quality of your products, the number of windows you need, the current condition of your home and your location. A lot of window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. Additional services will increase overall project costs.

With windows, efficiency is the most important factor for most homeowners. Efficient windows 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, purchasing certified energy-efficient windows can save Denville homeowners $287+ a year after replacing single-pane windows.

Something else that influences the total cost is the material you choose for your frame. Aluminum frames are usually the least pricey and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

There are typically two types of window installation services: full-frame and pocket installations.

Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has a great amount of damage. Full-frame installations involve more time and labor and will increase overall costs. 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 damage or rot, you will likely need a full-frame installation instead.

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

How We Choose the Best Window Installers in Denville

In our hunt to find the most reliable, eco-friendly window installers in Denville, the EcoWatch team examined many companies before deciding on these. Along with energy efficiency, we evaluated several window installers in Denville and ranked them using the following methodology:

Service Area

Since this is a guide for Denville, we paid more attention to companies that serve the city. There are certainly reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Denville.

Work Quality

When it comes to new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand of window 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

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have nice things to say about their experience with a certain company, you won't see it featured on EcoWatch.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers' prices, we awarded 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 that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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