How Installing Energy-Efficient Windows in Lake St. Louis Saves You Money

Switching to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here's more information on how switching out your windows could help you:

• Save money on energy bills: Once you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll need less energy to heat or cool your house.
• Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help raise the value of your property if you decide to sell.
• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.

Estimated Cost of Window Replacement in Lake St. Louis

Let’s go over the cost of installing new windows and the kinds of services you may need for your home.

How Much Do New Windows Cost?

Though the national average cost of replacing a single window is about $600, it can range from $200 to $1,200. But costs will vary significantly depending on your location, the number of windows you need, the quality of your products and the current condition of your home. A lot of window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. These extra services will increase overall project costs.

Whether or not you opt for energy-efficient windows is another factor that will determine the cost. These will almost always cost more than other windows, but on the other hand, you can save about $382 a year on your energy bills in Lake St. Louis.

We advise getting free quotes from several window installation companies to find the right windows and the company that works best for your budget.

What Services do Window Installers Offer?

There are generally two types of window installation services: full-frame and pocket installations.

Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has significant deterioration. Full-frame installations are more comprehensive and will increase overall costs. A pocket installation involves replacing a window within the existing frame, which is usually less expensive than a full-frame installation.

If you’re unsure which kind of window installation service you need, your installer should be able to help you out. In general, the choice depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Lake St. Louis

In our search to find the most reliable, eco-friendly window installers in Lake St. Louis, the EcoWatch Reviews team examined many companies before deciding on these. Along with energy efficiency, we reviewed window companies all across the state and assigned rankings using the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve Lake St. Louis so you can find the right window installation company near you.

Work Quality

When it comes to new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand you opt for. 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

Customer feedback is another super important review factor. If the majority of customers don’t have nice things to say about their experience with a certain installer, it won’t be featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers want 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. That’s why window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
