How Installing Energy-Efficient Windows in Thomas Saves You Money
There are several benefits of switching to energy-efficient windows. Some reasons you may want to consider making the switch include the following:
- 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. Switching to energy-efficient windows can help decrease that amount, which helps you save $459 a year on your bills.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can lower your carbon footprint by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Thomas
Let’s go over the cost of updating your windows and the types of services you may need for your home.
How Much Do New Windows Cost?
Even though the national average cost to replace a single window is about $600, it can range from $200 to $1,200. How much it will cost depends on several factors, such as material, the location of your home, number of windows, size, type and more.
It’s also worth noting that energy-efficient windows will typically cost more initially, but Energy Star predicts that upgrading the windows on your Thomas home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you’ll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Something else that influences the overall cost is the material of the frame you choose. Aluminum frames are typically the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
When considering window replacements, in general there are two types that your provider will offer: full-frame and pocket installations.
A full-frame installation replaces the complete window, including the sill, frame, trim and the window panes. As this type of installation is more involved, it will be more expensive than a pocket installation. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
Your window replacement company should be able to help you figure out what’s best for your needs. In Thomas, the decision will mostly depend on how old your home is and if there’s any damage. Wood can decay if it’s not maintained properly over the years, so it’s a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Thomas
In our hunt to make your home improvements easier and more eco-friendly in Thomas, EcoWatch landed on the above companies as the top window installation companies in the city. We’ve assessed the top window installation companies in Thomas mainly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows have been shown to reduce 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 installation companies that serve a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
When it comes to new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the type of window you choose. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the highest rates of customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including professionalism, warranty, quality of installation, quality of parts, cost and more.
Cost
This one is a give-and-take: similar to most services, cheap window installation companies are not going to provide the highest quality service. Still, we want to ensure we’re highlighting companies that offer a variety 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 have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Thomas’s climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Thomas window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Thomas, MI Window Replacement FAQs
How much should window installation cost?
The typical cost of replacing a window ranges from $450 to $650. There are a variety of factors that affect how much it costs, such as styles and sizes of windows, local labor costs, how energy-efficient the windows are, the number of windows, the materials used in designing the windows and your property’s location.
What type of window is the most energy-efficient?
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 often the most energy-efficient and are certified by the U.S. Department of Energy.
What services do window replacement companies do?
Window installation professionals cover the entire process — from replacing old windows with brand-new ones to cleaning up after the windows have been put in place. Additionally, some companies offer window manufacturing, customization and repairs.
Should I replace all my windows at the same time?
If your windows are greater than 20 years old, you most likely need to replace all of them. At that point, they are typically less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
