20 Best Window Companies in Lowell, MA (2025 Reviews)

How Installing Energy-Efficient Windows in Lowell Saves You Money

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

• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
• Save money on energy bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of residential energy use. Installing energy-efficient windows can help decrease that amount, which helps you save some money on your bills.
• Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Lowell

Windows come in different styles, purposes and shapes, so costs and services will vary considerably based on several factors. Below, we describe the typical cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

Generally, homeowners in Lowell can expect that most window installations will cost between $250 and $1,200, with the average cost sitting at about $600. These amounts vary based on the specifics of your installation, like number of windows, type, material, the location of your home, size and more.

With windows, efficiency is one of the most important factors for many homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Lowell homeowners $464+ per year after replacing single-pane windows.

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

What Services do Window Installers Offer?

Generally, there are two types of window replacement services companies provide: full-frame and pocket installations.

Full-frame installations involve replacing the total window, including the sill, trim and frame. You most likely need a full-frame installation when you want a new style or your window has considerable rot. Because these installations are more involved, they will increase the overall cost. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won’t cost as much, but you can’t do this type of installment if you have any pre-existing rot or water damage.

Your window installation company will be able to help you figure out what’s best for your needs. In Lowell, the decision will mostly be based on how old your home is and if there’s any moisture damage. Wood can decay if not maintained properly over the years, so it’s a good idea to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Lowell

EcoWatch reviews differ from other reviews, as we look at these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and ranked them using the following methodology:

Service Area

This one is 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

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

Customer Reviews

We analyzed patterns in recent online reviews to find the companies with the most customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including professionalism, quality of parts, quality of installation, cost, warranty and more.

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. For that reason, window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. Window installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
