How Installing Energy-Efficient Windows in Northwest Harwich Saves You Money
By switching to energy-efficient windows, you can enjoy several benefits, such as:
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, especially if you have an older home.
- Save on energy bills: Because energy-efficient windows reduce the amount of energy needed to heat or cool your home, they can help you save about $338 annually on your energy bills in Northwest Harwich.
- Better temperature control in your home: When you live in a city like Northwest Harwich where the winters can be cold, you often have to depend on your heater to keep your home warm. Energy-efficient windows can reduce how much heat is lost through your windows when heating your home.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Northwest Harwich
Let's go over the cost of window replacement and the types of services you may need for your home.
How Much Do New Windows Cost?
The average cost to replace one window is about $600 but can range from $200 to $1,200. But prices vary considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations, which will make your project cost more.
Bear in mind that energy-efficient windows may cost more, but Energy Star estimates the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
How much your window installation costs will also vary based on the type of material you choose for the frames. Wood windows are typically the most expensive, although it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
The first question to ask yourself when planning a window installation is: Do you need a full-frame installation or a pocket installation?
Full-frame installations are usually done when you want to change the style of your windows or your window has a lot of deterioration. With this service, your installers will replace the full window, including the frame, trim and sill. A pocket installation entails replacing a window without removing the whole frame, which is generally cheaper than a full-frame installation.
If you're still debating which kind of installation to get, you can talk to your installer and get their advice. The decision mostly depends on the age of your window frames and if there's any damage.

How We Choose the Best Window Installers in Northwest Harwich
EcoWatch reviews differ from other reviews because we examine these companies through a sustainability lens. We have assessed the top window installers in Northwest Harwich mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Because this is a guide for Northwest Harwich, we gave more points to companies that cover the city. There are certainly reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Northwest Harwich.
Work Quality
When picking new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand you opt for. 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
We analyzed trends in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including warranty, professionalism, cost, quality of installation, quality of parts and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a significant investment, so you'll want to make sure that investment is well protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Northwest Harwich's climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Northwest Harwich window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
