How Installing Energy-Efficient Windows in Oak Harbor Saves You Money

Upgrading to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here are more ways switching out your windows could benefit you:

• Save money on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Installing energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.
• Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its real estate value.
• Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.
• Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Oak Harbor

Each window installer provides various services and has different prices depending on several factors.

How Much Do New Windows Cost?

The national average cost to replace a single window is about $600 but can range from $200 to $1,200. This is because 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 the location of your property.

With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Oak Harbor homeowners $249+ each year after replacing single-pane windows.

How much your window installation costs will also vary based on the type of window material you choose for the frames. Wood windows are generally the most expensive, although it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

The first thing to ask yourself when planning to replace your windows is: Do you need a full-frame installation or a pocket installation?

A full-frame installation is a replacement of the total window. This service involves taking out the old window, the sill, and the exterior and interior trim. It can also involve extra materials, such as insulation and drip edges, which increase the overall cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. Pocket installations are simpler and won’t carry as large a bill because they entail simply replacing the window within its existing frame. But if the frame has any damage, you may have to get 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 Oak Harbor, the choice will mostly be based on how much damage there is currently and the age and condition of your existing frames.

How We Choose the Best Window Installers in Oak Harbor

EcoWatch reviews differ from other reviews since we assess these companies through a sustainability lens. We’ve assessed the top window installers in Oak Harbor mainly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Since this is a guide for Oak Harbor, we paid more attention to companies that provide services to the city. There are certainly reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Oak Harbor.

Work Quality

When it comes to new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand of window you opt for. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent customer feedback to determine the companies with the highest rates of 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 warranty, quality of installation, professionalism, cost, quality of parts and more.

Cost

This one is a give-and-take: similar to other services, cheap window installation companies may not provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that provide a variety of price and financing options so they’re accessible to most homeowners.

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

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