How Installing Energy-Efficient Windows in Monmouth Saves You Money
Energy-efficient windows can provide benefits in more than one way. Here are a few reasons you may want to take the plunge and make the switch:
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
- Reduce your carbon footprint: In Monmouth, you can cut your indirect greenhouse gas emissions by about 163 pounds per year once you switch to energy-efficient windows.
- Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Switching to energy-efficient models can help decrease how much you have to pay, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in Monmouth
Windows come in varying shapes and sizes, so costs and services will vary remarkably. Here are the typical costs and the primary services that you can find from the average window installation company.
How Much Do New Windows Cost?
According to our market research, the average cost of installing a single window is around $600. However, window replacement costs can range from $200 to $1,200 for each window. But costs will vary considerably based on the number of windows you need, the quality of your products, the current condition of your home and your location. Many window companies also offer door installations and other add-ons like coating, baths, shutters and more. These extra services will increase overall project costs.
It's also worth noting that energy-efficient windows will cost more initially, but Energy Star estimates that upgrading the windows on your Monmouth home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
We recommend requesting free quotes from several window companies to find the one that works best for you.
What Services do Window Installers Offer?
When considering window replacements, in general there are two kinds that your installer will have: full-frame and pocket installations.
Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has a great amount of deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are on the simpler end and won't carry as large a bill, but you can't do this kind of installment if you have any pre-existing rot or water damage.
Your window replacement company will be able to help you understand what's best for your needs. In Monmouth, the decision will mostly be based on how old your windows are and if there's any damage. Wood can decay if not properly maintained 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 Monmouth
EcoWatch reviews are different from other reviews, as we're examining these companies through a sustainability lens. Along with energy efficiency, we reviewed each installer and assigned rankings using the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve Monmouth so you can find the right window installation company near you.
Work Quality
When picking new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the type of window you choose. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent customer feedback to find 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 nearly every category, including warranty, quality of parts, professionalism, quality of installation, cost and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing the prices of providers, 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 to many homeowners. That's why window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Monmouth's climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Monmouth window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Monmouth, ME Window Replacement FAQs
How much should window installation cost?
The typical cost of replacing one window can range between $450 and $650. There are many factors that influence the cost, such as local labor costs, how energy-efficient the windows are, the number of windows, your property's location, styles and sizes of windows and the materials used in designing the windows.
What are the most common kinds of replacement windows?
The most common kinds of windows for homes are casement windows, transom windows, bay windows, picture windows, slider windows, awning windows and double-hung and single-hung windows.
Do you really need to use a window installation company?
Unless you have experience with home improvement projects and have the time to replace your own windows, we recommend hiring the pros. The window installation process is complicated and can take anywhere from four to six hours for one window. Although it's tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and safer option.
How long does it typically take to install windows?
Since a window takes about 30 minutes to install, around 16 windows can be installed in an 8-hour work day.
