How Installing Energy-Efficient Windows in Merrimack Saves You Money

Upgrading to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here's more information on how upgrading your windows could help you:

• Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 152 pounds.
• Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Installing energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
• Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
• Protect your investment: When you have an older home, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its real estate value.

Estimated Cost of Window Replacement in Merrimack

Let's take a look at the cost of window replacement and the types of services you may need for your home.

How Much Do New Windows Cost?

According to our market research, the national average cost to install a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. But costs will vary considerably depending on the number of windows you need, your location, the quality of your products and the current condition of your home. Many window companies also offer door installations and other add-ons like baths, coating, shutters and more. These extra services will increase overall project costs.

Keep in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.

Getting free quotes from several providers is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

The first step of an installation is to figure out whether you should get 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 a new style for your windows or when it has a great amount of rot or deterioration. Full-frame installations are more comprehensive and will increase overall costs. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

If you're unsure which type of window installation service you need, your installer should be able to help you out. Generally, the decision is based 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 Merrimack

In our search to make your home improvements easier and more eco-friendly in Merrimack, EcoWatch evaluated many companies before landing on these. Along with energy efficiency, we evaluated several window installers in Merrimack and assigned rankings based on the following methodology:

Service Area

Because this is a guide for Merrimack, we paid more attention to companies that provide services to the city. There are certainly other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Merrimack.

Work Quality

When selecting new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand you get. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don't have nice feedback 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 awarded 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. For that reason, window installation companies with 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 installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
