How Installing Energy-Efficient Windows in East Harwich Saves You Money
There are several perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the change are the following:
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can cut your carbon footprint by about 12%, according to Energy Star.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help raise the value of your property if you decide to sell.
- Save on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Upgrading to energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
Estimated Cost of Window Replacement in East Harwich
When researching window installation, each company provides different services and costs. Let's look at some typical costs and services.
How Much Do New Windows Cost?
Although the average of replacing a single window is around $600, it can range from $200 to $1,200. These numbers vary depending on the specifics of your installation, such as size, type, the location of your home, material, number of windows and more.
With windows, efficiency is one of the most important factors for many homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — particularly during the winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save East Harwich homeowners $338+ per year after replacing single-pane windows.
Something else that affects the total cost is the material you choose for your frame. Aluminum frames are generally the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames are the most expensive because 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?
In general, there are two types of window replacement services companies offer: full-frame and pocket installations.
Full-frame installations are usually done when you want a new style or your window has significant rot. With this service, your professionals will replace the whole window, including the frame, sill and trim. Pocket installations are on the simpler end and won't carry as large a bill because they involve merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.
If you're still trying to decide which kind of installation to get, you can ask your installer and get their advice. The choice mostly is influenced by the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in East Harwich
EcoWatch differs from most reviewers, as we evaluate these companies through a sustainability lens. We've assessed the best window installers in East Harwich mainly based on energy efficiency, 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 electricity 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 East Harwich, we paid more attention to companies that serve the city. There are other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in East Harwich.
Work Quality
When choosing new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the type of window you choose. 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
Another self-explanatory yet very important review factor is customer feedback. If most customers don't have positive feedback about their experience with a certain window installation company, you won't see it featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, 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 to many homeowners. That's why 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 been in the industry for a while. Window installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
East Harwich, MA Window Replacement FAQs
How much should a window install cost?
The national average cost of installing one window is around $600 but can range from $200 to $1,200, depending on several factors. The price is generally dependent on the location of your property, the size of the window and the type and material of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
Which type of window is the best?
A window's energy efficiency is influenced by a variety of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.
Can you replace your own windows?
If you're handy and know how to replace a window, it's possible to install your own windows. However, if you don't have the time or experience, we don't recommend it.
What time of year should I replace my windows?
Replacement windows can be installed at any time, but autumn might be the best season. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your house, so the temperature outside isn't necessarily a big factor. Most importantly, the weather should be dry.
How often should you replace your windows?
Windows usually last around 20 to 30 years, but anytime you see damage on your windows, it's a good time to have an expert take a look at them to determine if they are in need of a repair or replacement.
