How Installing Energy-Efficient Windows in Kennebunkport Saves You Money
When you upgrade to energy-efficient windows, you may see several perks, including:
- Reduce your carbon footprint: By using less energy once upgrading to energy-efficient windows, you'll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if you have an older home.
- Save money on power bills: Since energy-efficient windows decrease how much energy you need to heat or cool your home, the switch can help you save around $383 annually on your energy bills in Kennebunkport.
Estimated Cost of Window Replacement in Kennebunkport
Windows come in varying shapes and sizes, so costs and services will vary greatly. Here are the typical costs and the primary services that you'll find from the average window installation company.
How Much Do New Windows Cost?
Generally, homeowners in Kennebunkport can anticipate that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. How much it will cost varies depending on several factors, such as the location of your home, material, size, number of windows, type and more.
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 exact savings will vary based on your local climate, energy rates and individual home characteristics.
We recommend requesting free quotes from multiple window installers to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
When it comes to window installations, there are typically two types that your installer will offer: full-frame and pocket installations.
A full-frame installation replaces the complete window, including the windowsill, frame, trim and the window panes. As this type of installation is more involved, it will cost more than a pocket installation. A pocket installation entails replacing a window without taking out the complete frame, which is generally cheaper than a full-frame installation.
If you're unsure which type of window installation service you should get, your installer can assist you. Typically, the decision is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Kennebunkport
In our search to find the most reliable, eco-friendly window installers in Kennebunkport, EcoWatch examined dozens of companies before deciding on these. Along with energy efficiency, we reviewed each installer 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 Kennebunkport so you can find the best window installation company near you.
Work Quality
We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each company featured in our guide to make sure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including quality of parts, quality of installation, warranty, professionalism, cost and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers' prices, we awarded higher points 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
Because of Kennebunkport's climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Kennebunkport window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
