How Installing Energy-Efficient Windows in Dellwood Saves You Money
When you upgrade to energy-efficient windows, you may see some benefits, such as:
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Dellwood, that's about 763 pounds per year on average.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Save money on energy bills: Because energy-efficient windows decrease the amount of energy needed to heat or cool your home, the switch can help you save about $376 annually on your energy bills in Dellwood.
- Protect your investment: If you have an older home, 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 home if you decide to sell.
Estimated Cost of Window Replacement in Dellwood
When researching window installation, each company offers varying services and costs. Let's take a look at some average costs and services.
How Much Do New Windows Cost?
According to our research, the average cost of replacing a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. This is because window installations are based on several factors specific to your home, like the size, material and number of windows you need to install, as well as where your property is located.
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 $376 a year on your energy bills in Dellwood.
The cost of your window installation will also vary based on the kind of window material you choose for the frames. Wood windows are typically the most expensive, but it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
When it comes to window installations, in general there are two kinds that your provider will offer: 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 new style for your windows or when it has significant damage. Full-frame installations are more involved and will increase overall costs. Pocket installations are simpler and won't cost as much because they entail simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may have to get a full-frame installation instead.
Your window installer can help you decide which type of installation you should get.

How We Choose the Best Window Installers in Dellwood
In our search to find the most reliable, eco-friendly window installers in Dellwood, the EcoWatch team landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we reviewed several window installers in Dellwood and ranked them using the following methodology:
Service Area
Since this is a guide for Dellwood, we paid more attention to companies that cover the city. There are certainly other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Dellwood.
Work Quality
When picking new windows, the quality and range of services can often play just as important of a role in overall efficiency 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
Customer feedback is another super important review factor. If the majority of customers don't have positive feedback about their service from a certain window installation company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window installers are not going to provide the highest quality service. Still, we want to make sure we're highlighting companies that provide a spectrum 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 offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Dellwood's climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Dellwood window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Dellwood, MO Window Replacement FAQs
What is the typical cost to install new windows?
The average cost of installing a single window ranges between $450 and $650. There are several factors that influence how much it costs, such as the number of windows, the materials used in designing the windows, local labor costs, how energy-efficient the windows are, styles and sizes of windows and your property's location.
What are the most common kinds of replacement windows?
The most common types of windows for homes are transom windows, double-hung and single-hung windows, casement windows, awning windows, slider windows, bay windows and picture windows.
When should I use a window installation company?
You should use a window installation professional whenever you need to upgrade your windows. Installing windows is a complicated process that can be difficult to do on your own, so it's best left to the professionals.
How often should you replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Other than that, if your windows have any damage on them, or they have become difficult to operate, they may be in need of replacement.
