How Installing Energy-Efficient Windows in Harwich Saves You Money
By switching to energy-efficient windows, you and your family can take advantage of several benefits, such as:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
- Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can lower your carbon footprint by about 12%, according to Energy Star.
- Save on energy bills: Once you switch to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll need less energy to heat or cool your home.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if your home is on the older side.
Estimated Cost of Window Replacement in Harwich
Windows come in various shapes and sizes, so costs and services will differ greatly. Here are the average costs and services that you’ll find from the average window installation company.
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 about $600. How much it will cost is based on several factors, such as type, size, the location of your home, material, number of windows and more.
With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows 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 Harwich homeowners $338+ each year after replacing single-pane windows.
Asking for free quotes from multiple installers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
When it comes to window replacements, there are generally two kinds that your provider will offer: full-frame and pocket installations.
A full-frame installation is a total window replacement. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves other materials, including insulation and drip edges, which increase the total cost of the project. It’s also worth noting that you may have to touch up the paint around the window after a full-frame installation. Pocket installations are on the simpler end and won’t cost as much, as they entail merely replacing the window within its existing frame. But if the frame has any damage, you should opt for a full-frame installation instead.
If you’re hiring a reputable window installation company, your company will be able to recommend the best type for your project. In Harwich, the choice will mostly be based on the efficiency of your home and the age and condition of your existing frames.

How We Choose the Best Window Installers in Harwich
EcoWatch differs from most reviewers because we examine these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in Harwich and ranked them using the following methodology:
Service Area
Since this is a guide for Harwich, we only included companies that serve the city. There are other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Harwich.
Work Quality
When picking new windows, the quality and breadth of services can often play 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
Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have nice things to say about their experience with a certain installer, it won’t be featured on EcoWatch.
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 scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important. That’s why window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Harwich’s climate, homeowners will want to mitigate water damage, low efficiency and rot. 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
What is the average cost to replace windows?
The national average cost of replacing a single window is about $600 but can range between $200 and $1,200, based on a few different factors. The price is often dependent on the type and material of the window, the size of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.

The most common types of windows for homes are slider windows, transom windows, double-hung and single-hung windows, awning windows, bay windows, picture windows and casement windows.
