How Installing Energy-Efficient Windows in Lowell Saves You Money

There are quite a few benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the change are the following:

  • 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.
  • Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by 139 pounds per year on average.
  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if your home is on the older side.
  • Save on power bills: Once you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% because you'll use less energy to heat or cool your home.

Estimated Cost of Window Replacement in Lowell

Windows come in varying shapes and sizes, so costs and services will vary tremendously. Here are the average costs and services that you'll find from the average window installation company.

How Much Do New Windows Cost?

Even though the typical of replacing one window is about $600, it can range from $200 to $1,200. How much it will cost varies based on several factors, including material, the location of your home, type, size, number of windows and more.

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

Getting free quotes from multiple providers is the best way to figure out which one will work best for your budget.

What Services do Window Installers Offer?

The first question to ask yourself when planning a window installation is: Do you want a full-frame installation or a pocket installation?

Full-frame installations involve replacing the complete window, including the trim, sill and frame. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable rot. Because full-frame installations are more involved, they will increase the total cost. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.

If you're hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Lowell, the decision 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 Lowell

The EcoWatch Reviews team is different from most reviewers, as we look at these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and ranked them using the following methodology:

Service Area

Since this is a guide for Lowell, we gave more points to companies that provide services to the city. There are other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Lowell.

Work Quality

When it comes to new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand of window you choose. 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

Customer feedback is another super important review factor. If most customers don't have positive things to say about their service from a certain window installation company, you won't see it featured on EcoWatch.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed previously, windows are a significant investment, so you'll want to make sure that investment is well protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Due to Lowell's climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Lowell window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Lowell, MA Window Replacement FAQs

What is the average cost to install windows in a home?

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

What kind of window is the most energy-efficient?

A window's energy efficiency is affected by a number of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.

What services do window replacement companies offer?

Window installation professionals travel to your property to remove your old windows and replace them with new ones. Some companies install products made by other companies, whereas others install their own windows. The installer will also clean up after the installation.

How long does it usually take to install windows?

Since the average installation time of a window is 30 minutes, around 16 windows can be installed during an 8-hour work day.

Should I replace all my windows at the same time?

If you're upgrading your windows because of energy-efficiency, replacing all your windows at the same time is the only way to gain that benefit. On the other hand, if you have just one or two windows that are damaged or leaky, you can replace just those.
