How Installing Energy-Efficient Windows in Brentwood Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here's more information on how switching out your windows could help you:
- Decrease your carbon footprint: In Brentwood, you can cut your indirect greenhouse gas emissions by about 763 pounds per year after you switch to energy-efficient windows.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: When you have an older home, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
- Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Upgrading to energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in Brentwood
Windows come in various purposes, shapes and styles, so costs and services will vary tremendously based on several factors. Below, we describe the average cost and services that you'll find from window installers.
How Much Do New Windows Cost?
The typical cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. This is because the cost of window installations depend on several factors specific to your home, such as the size, material and number of windows you need to install, as well as the location of your property.
With windows, efficiency is the most important factor for many homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Brentwood homeowners $376+ each year after replacing single-pane windows.
Requesting free quotes from multiple companies is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
The first question to ask yourself when planning a window installation is: Should you get a full-frame installation or a pocket installation?
Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has a great amount of deterioration. Full-frame installations are more comprehensive and will increase overall costs. A pocket installation means replacing a window within the existing frame, which is usually less expensive than a full-frame installation.
Your window installation company can recommend the best type for your project. In Brentwood, the decision will mostly be influenced by how much damage there is currently and the age of your existing frames.

How We Choose the Best Window Installers in Brentwood
In our hunt to find the most reliable, eco-friendly window installers in Brentwood, the EcoWatch team landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we evaluated several window installers in Brentwood and ranked them based on the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the right window installation company near you.
Work Quality
When it comes to new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand of window you opt for. We do give window installers higher marks 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 determine the companies with the most customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including quality of installation, professionalism, quality of parts, cost, warranty 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. On the other hand, we want to ensure 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. That's why window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Brentwood's climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Brentwood window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Brentwood, MO Window Replacement FAQs
What is the typical cost to replace windows in a home?
The average cost of replacing a window ranges from $450 to $650. There are several factors that affect how much it costs, which include styles and sizes of windows, the number of windows, your property's location, how energy-efficient the windows are, local labor costs and the materials used in designing the windows.
What are the different kinds of windows?
The most common kinds of windows for homes are transom windows, double-hung and single-hung windows, picture windows, bay windows, casement windows, awning windows and slider windows.
Can I replace my own windows?
Even though you can install your own windows, doing so requires a lot of time and handiness. Using a window replacement company can help guarantee that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.
When is it time to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may be in need of replacement.
Should I replace my windows all at once?
If your windows are more than 20 years old, it's probably time to replace all of them. At that point, they are usually less efficient, draftier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
