Why you can trust EcoWatch
Although renewable energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your home's efficiency can also have a considerable impact on home energy conservation.

Installing new, efficient windows on your home can help you save money every month on your electric bills — and you can help the environment as well.
Efficient windows are particularly important in Loch Lomond, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $360 per year.

How Installing Energy-Efficient Windows in Loch Lomond 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 on electricity bills: Because energy-efficient windows reduce how much energy you need to heat or cool your home, the switch can help you save around $360 annually on your energy bills in Loch Lomond.
- Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can cut your carbon footprint by about 12%, according to Energy Star.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if your home is on the older side.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
Estimated Cost of Window Replacement in Loch Lomond
Let's go over the cost of window replacement and the kinds of services you may need for your home.
How Much Do New Windows Cost?
The typical cost to install a single window is about $600 but can range anywhere from $200 to $1,200. How much it will cost you varies based on several factors, such as material, type, number of windows, size, the location of your home and more.
It's important to bear in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Loch Lomond homeowners $360+ a year when replacing single-pane windows.
Costs will also vary based on the material of your frame. Aluminum frames are the least expensive. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
There are generally two kinds of window replacement services: full-frame and pocket installations.
Full-frame installations involve replacing the total window, including the sill, trim and frame. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable damage or rot. Full-frame installations are more involved and will raise the total cost. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.
If you're not sure which window installation service you need, your installer can help you out. In general, the choice depends 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 Loch Lomond
In our hunt to find the most reliable, eco-friendly window installers in Loch Lomond, EcoWatch evaluated dozens of companies before landing on these. Along with energy efficiency, we analyzed 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 Loch Lomond so you can find a quality window installation company near you.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each company included on this list to make sure its contractors are well-qualified and that the company has gotten lots 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 reflects the quality of services across most other categories, including cost, quality of installation, warranty, professionalism, quality of parts and more.
Cost
This one is a give-and-take: as with other services, cheap window installation companies won't always provide the most quality service. Still, we want to make sure we're highlighting companies that offer a wide range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. That's why window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for a while. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Loch Lomond, VA Window Replacement FAQs
How much should a window install cost?
The national average cost of replacing a single window is about $600 but can range between $200 and $1,200, depending on a variety of factors. The price is generally influenced by the type and material of the window, the location of your property and the size of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What are the different types of windows?
The most common kinds of windows for homes are casement windows, awning windows, bay windows, slider windows, transom windows, picture windows and double-hung and single-hung windows.
When do I 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 a professional. The window installation process is complicated and can take anywhere from four to six hours for a single window. Although it's tempting to try to save money by doing it yourself, hiring a company is a faster, more efficient and safer option.
When is the best time of year to replace windows?
While you can install windows any time of year, warmer weather is generally better for installing replacement windows. Additionally, it shouldn't be raining, as rain can make the installation more difficult.
Should I replace all my windows at once?
If your windows are greater than 20 years old, it's probably time to replace all of them. At that point, they are typically less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
