How Installing Energy-Efficient Windows in Mercedes Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to make the switch:
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
- Save money on power bills: Installing energy-efficient windows reduces your energy bills by about 12% because you use less energy.
- Decrease your carbon footprint: By using less energy once upgrading to Energy Star certified windows, you’ll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
Estimated Cost of Window Replacement in Mercedes
Windows come in varying styles, shapes and purposes, so costs and services will vary considerably depending on your project. Below, we go over the average cost and services that you can get from window replacement companies.
How Much Do New Windows Cost?
The national average cost to install one window is about $600 but can range anywhere from $200 to $1,200. But costs will differ significantly based on the current condition of your home, your location, the number of windows you need and the quality of your products. Many window companies also offer replacement door installations and other add-ons like baths, shutters, coating and more. Additional services will increase your overall project costs.
It’s also worth noting that energy-efficient windows will almost always cost more upfront, but Energy Star predicts that switching out the windows on your Mercedes 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. How much you’ll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Another factor that influences the total cost is the material you pick for your frame. Aluminum frames are typically the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
In general, there are two types of window installation services companies offer: full-frame and pocket installations.
A full-frame installation replaces the complete window, such as the windowsill, frame, trim and the window panes. Because this kind of installation requires more time, it will be more expensive than a pocket installation. A pocket installation entails replacing a window without removing the whole frame, which is generally less expensive than a full-frame installation.
Your window installation company can advise you on the best type for your project. In Mercedes, the choice will mostly be influenced by how much damage there is currently and the condition of your existing frames.

How We Choose the Best Window Installers in Mercedes
In our search to make your home improvements easier and more eco-friendly in Mercedes, the EcoWatch team landed on the above companies as the best window installation companies in the city. We have assessed the top window installers in Mercedes mostly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve Mercedes so you can find the right window installation company near you.
Work Quality
We’re willing to bet 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 technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have nice feedback about their service from a certain installer, you won’t see it featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window installation companies are not going to provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed, windows are a considerable investment, so you’ll want to be certain that investment is well protected. Window installation companies that have 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 been in the industry for quite some time. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Mercedes, TX Window Replacement FAQs
How much should a window install cost?
The national average cost to replace a single window is about $600 but can range from $200 to $1,200, based on a variety of factors. The price is generally influenced by the location of your property, the type and material of the window and the size of the window. Also, keep 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?
There are several different types of windows you can get for your house, including double-hung and single-hung windows, casement windows, bay windows, transom windows, awning windows, slider windows and picture windows.
Can you install your own windows?
Although you can install your own windows, doing so requires a lot of time and experience with home improvement projects. Hiring a professional can help ensure that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.
Should I replace all my windows at the same time?
If your windows are greater than 20 years old, it’s probably time to replace all of them. At that point, they are often less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.
