Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Whether you're updating for aesthetics or have damaged windows, windows play a vital role in conserving energy in your home. The Department of Energy estimates that heat or cool air lost through traditional or outdated windows could account for nearly 30% of heating and cooling costs. In Merrimac, where the electric bills are an average of $35 per month, that's almost $$124 per year wasted.

Replacement windows improve the insulation in your home, not only making you and your family more comfortable during extreme temperatures, but also saving you money and helping the environment.

Unlike other review sites, EcoWatch ranks window replacement companies based on energy efficiency while also considering cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Merrimac Saves You Money

By switching to energy-efficient windows, you can benefit in several ways, including:

  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Save on energy bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of energy use in your home. Upgrading to energy-efficient windows can help lower that amount, which helps you save more on your bills.
  • Reduce your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 139 pounds.
  • Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its value.

Estimated Cost of Window Replacement in Merrimac

Each window replacement company provides varying services and has different price points based on a few factors.

How Much Do New Windows Cost?

Generally, homeowners in Merrimac can expect that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. This is because the cost of window installations depend on a variety of factors specific to your home, like the size, material and number of windows you need to replace, as well as the location of your property.

It's also worth keeping in mind that energy-efficient windows will typically cost more initially, but Energy Star estimates that upgrading the windows on your Merrimac home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you'll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Requesting free quotes from several installers is the best way to find out which one is right for you.

What Services do Window Installers Offer?

The first step of a window replacement is to think about whether you need a full-frame or pocket installation.

Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has a great amount of deterioration. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations are on the simpler end and won't carry as large a bill because they entail merely replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.

If you're not sure which window installation service you should get, your installer should be able to help you out. In general, the choice depends on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Merrimac

In our search to make your home improvements easier and more eco-friendly in Merrimac, the EcoWatch team chose the above companies as the top window installation companies in the city. We have evaluated the top window installation companies in Merrimac mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

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 looking for professionals who do a great job installing windows. We've vetted each company included in our guide to make sure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent customer feedback to determine the companies with the most consistent customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including cost, quality of installation, professionalism, warranty, quality of parts and more.

Cost

This one is a give-and-take: similar to other services, cheap window installers may not provide the most quality service. On the other hand, we want to ensure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.

Warranty

As discussed previously, windows are a significant investment, so you'll want to be certain that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a proven track record in the industry. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Merrimac, MA Window Replacement FAQs

How much should window installation cost?

The national average cost to install one window is around $600 but can range between $200 and $1,200, depending on a variety of factors. The price is often dependent on the size of the window, the type and material of the window and the location of your property. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

What type of window is the best for energy efficiency?

A window's energy efficiency depends on several factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.

Do I really have to use a window installation company?

You should hire a window installation company whenever you want to replace your windows. Installing windows is a complex process that can take a lot of time, so it's best handled by the professionals.

When is the best time of year to replace windows?

Though you can install windows any time of year, warmer weather is generally better for replacing windows. Additionally, the weather should be dry, as rain can make the installation harder.

How do you know it's time to replace your windows?

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to operate, they may need to be replaced.
