How Installing Energy-Efficient Windows in Old Town Saves You Money
Energy-efficient windows can provide benefits in several ways. Here are a few reasons you may want to take the plunge and make the switch:
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Installing energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its value.
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Old Town, that's about 163 pounds per year on average.
Estimated Cost of Window Replacement in Old Town
Windows come in various shapes and sizes, so costs and services will vary tremendously. Here are the average costs and services that you'll find from window installers.
How Much Do New Windows Cost?
Generally, homeowners in Old Town can anticipate that most window installations will cost between $250 and $1,200, with the average cost at around $600. Costs will differ significantly depending on your location, the quality of your products, the current condition of your home and the number of windows you need. Many window companies also offer replacement door installations and other add-ons like coating, baths, shutters and more. Additional services will increase overall project costs.
Keep in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.
Another factor that influences the total cost is the material you select for your frame. Aluminum frames are generally the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
The first question to ask yourself when planning a window installation is: Do you need a full-frame installation or a pocket installation?
Full-frame installations entail replacing the complete 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 or deterioration. Full-frame installations are more involved and will increase the overall cost. A pocket installation entails replacing a window within the existing frame, which is generally cheaper than a full-frame installation.
If you're still trying to decide which kind of installation you need, you can talk to your installer and get their recommendation. The decision mostly is influenced by how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Old Town
In our search to find the most reliable, eco-friendly window installers in Old Town, the EcoWatch team examined many companies before landing on these. We have assessed the top window installers in Old Town primarily based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Because this is a guide for Old Town, we paid more attention to companies that serve the city. There are other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Old Town.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each company featured in our guide to ensure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don't have nice things to say about their service from a certain installer, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window installers won't always provide the highest quality service. On the other hand, 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. That's why window installation companies that provide 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 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.
