That's not great for your wallet or the environment, but one of the best window installation companies can help you with that.

How Installing Energy-Efficient Windows in Westminster Saves You Money
Switching to energy-efficient windows can help 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:
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
- Decrease your carbon footprint: By using less energy once you upgrade to energy-efficient windows, you'll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Save on energy bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Switching to energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in Westminster
Each window installer provides varying services and has varying costs based on a few factors.
How Much Do New Windows Cost?
Even though the national average to replace a single window is about $600, it can range from $200 to $1,200. These figures vary based on specific characteristics of your installation, including size, the location of your home, material, number of windows, type and more.
Whether or not you want to install energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $482 a year on your energy bills in Westminster.
Something else that affects the overall cost is the material of the frame you select. Aluminum frames are typically the least pricey and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
Generally, there are two kinds of window replacement services companies offer: full-frame and pocket installations.
Full-frame installations are usually done when you want a new style or your window has significant rot or deterioration. With this service, your professionals will replace the whole window, including the sill, frame and trim. 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 replacement company should be able to help you figure out what's best for your needs. In Westminster, the decision will mostly depend on the age of your windows and if there's any damage. Wood can decay if not properly maintained over the years, so it's good to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Westminster
In our search to make your home improvements easier and more eco-friendly in Westminster, the EcoWatch Reviews team assessed many companies before deciding on these. We have evaluated the top window installation companies in Westminster mainly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can cut your power 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 installers that serve the Westminster area so you can find a quality window installation company near you.
Work Quality
We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each company included on this list 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 installer, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window companies may not provide the highest quality service. Still, we want to make sure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Westminster, MA Window Replacement FAQs
How much does window installation cost?
The typical cost to install one window can range between $450 and $650. There are a variety of factors that affect the cost, which include your property's location, how energy-efficient the windows are, local labor costs, styles and sizes of windows, the number of windows and the materials used in designing the windows.
What are the most common types of replacement windows?
The most common types of windows for homes are awning windows, transom windows, bay windows, slider windows, picture windows, double-hung and single-hung windows and casement windows.
When do I need to use a window installation company?
Unless you have home repair skills and have the tools needed to replace your own windows, we recommend hiring a professional installer. The process of installing windows is complicated and can take anywhere from four to six hours for a single window. Although it's tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and much safer option.
When is the best time of year to replace windows?
Replacement windows can be installed at any time, but warmer weather is typically better. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your house, so the temperature outside isn't necessarily a big factor. What's most important is that the weather should be dry.
Should I replace all my windows at the same time?
If you're upgrading your windows to get more efficient windows, replacing all your windows at the same time is the only way to see a noticeable difference. However, if you have just one or two windows that are broken or leaky, you can replace just those.
