How Installing Energy-Efficient Windows in Harwich Saves You Money
When you upgrade to energy-efficient windows, you may see several benefits, such as:
- Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out harmful UV rays.
- More efficient energy use in your home: Because the summers can get pretty warm in Harwich, homeowners usually rely on their air conditioner a lot. Energy-efficient windows reduce how much cool air is lost through your windows, making it easier to keep your home cool.
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its value.
- Save money on power bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you need less energy.
Estimated Cost of Window Replacement in Harwich
Windows come in various shapes, purposes and styles, so costs and services will differ tremendously based on several factors. Below, we go over the typical cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
Typically, Harwich homeowners can expect their window installations to range from $250 to $1,200. The most common installations sit at approximately $600. How much it will cost you depends on several factors, including type, the location of your home, number of windows, size, material and more.
Whether or not you pick energy-efficient windows is another factor that will determine the cost. These will typically cost more than other windows, but on the other hand, you can save about $338 a year on your energy bills in Harwich.
We advise getting free quotes from multiple window installers to find the one that works best for you.
What Services do Window Installers Offer?
There are generally two types of window installation services: full-frame and pocket installations.
A full-frame installation is a total window replacement. It involves removing the old window, the windowsill, and the exterior and interior trim. It also involves other materials, like insulation and drip edges, which raise 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. A pocket installation means replacing a window within the existing frame, which is usually cheaper than a full-frame installation.
Your window installation company should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Harwich
In our hunt to make your home improvements easier and more eco-friendly in Harwich, the EcoWatch team examined dozens of companies before landing on these. We have evaluated the best window installation companies in Harwich mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find the best window installation company near you.
Work Quality
We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each company featured in our guide to ensure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the most customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including quality of installation, professionalism, cost, quality of parts, warranty and more.
Cost
Cheaper windows certainly don't 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 awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a considerable 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 Harwich's climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of 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.
Harwich, MA Window Replacement FAQs
How much should a window install cost?
The average cost to install a window can range between $450 and $650. There are a variety of factors that influence the cost, including the number of windows, local labor costs, styles and sizes of windows, the materials used in designing the windows, your property's location and how energy-efficient the windows are.
Which type of window should I get?
A window's energy efficiency depends on 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 since they are certified by the U.S. Department of Energy.
Can you install your own windows?
Although you can install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Hiring a professional can help guarantee that the job is done properly and that you can avoid spending the time and effort of doing it yourself.
How long does it typically take to install windows?
Each window takes about 30 minutes to install depending on the type of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
How often should you replace windows?
Windows typically last 20 to 30 years, but anytime you notice 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.
