How Installing Energy-Efficient Windows in Stow Saves You Money

There are several benefits of switching to energy-efficient windows. A few reasons you may want to consider making the change include the following:

  • Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 139 pounds.
  • Save on energy bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you need less energy.
  • Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.
  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if you have an older home.

Estimated Cost of Window Replacement in Stow

When researching window installation, each company provides varying services and costs. Let's look at some typical costs and services.

How Much Do New Windows Cost?

Although the typical of installing a single window is about $600, it can range from $200 to $1,200. How much it will cost you varies depending on several factors, like size, the location of your home, material, number of windows, type and more.

It's important to keep in mind that windows with the best efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Stow homeowners $396+ a year when replacing single-pane windows.

We recommend getting free quotes from several window companies to find the one that works best for your budget.

What Services do Window Installers Offer?

In general, there are two kinds of window replacement services you can get: full-frame and pocket installations.

Full-frame installations are necessary when you want to change the style of your windows or your window has significant deterioration. With this service, your installers will replace the full window, including the trim, frame and sill. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any damage or rot, you will likely need 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 Stow, the choice will mostly be based on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Stow

EcoWatch differs from other reviewers, as we assess these companies through a sustainability lens. Along with energy efficiency, we reviewed each installer and ranked them based on the following methodology:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the right window installation company near you.

Work Quality

We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer in our guide to make sure its technicians are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have positive things to say about their service from a certain window installation company, it won't be featured on EcoWatch.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers' prices, we gave higher scores 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 that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Stow, MA Window Replacement FAQs

What is the average cost to replace windows?

The typical cost to replace a single window can range between $450 and $650. There are a variety of factors that affect how much it costs, including how energy-efficient the windows are, the materials used in designing the windows, local labor costs, styles and sizes of windows, the number of windows and your property's location.

Which type of window is the best?

Generally, double-pane windows are more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. If you want to be sure you're getting the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.

Do you really need to use a window installation company?

You should use a window installation company whenever you want to replace your windows. Installing windows is a complex process that can be difficult and time-consuming, so it's best left to the professionals.

How long does window installation usually take?

Since the average installation time is 30 minutes per window, about 16 windows can be installed in an 8-hour work day.

Should I replace my windows all at the same time?

If you're upgrading your windows to save on your energy bills, replacing all your windows together is the only way to see a noticeable difference. However, if you have just a few windows that are damaged or drafty, you can replace just those.
