All The Benefits Of Replacing Your Windows

According to EnergyStar “Heat gain and heat loss through windows are responsible for 25%–30% of residential heating and cooling energy use.” We have found that upgrading our clients to energy-efficient windows boosted comfort, reduced their energy bills by 9 to 13 percent, and blended their home’s historic charm with modern efficiency.

Creve Coeur home values have steadily increased 13.82% over the last 2 years which gives us confidence in the data from that homeowners can expect a return on investment of roughly 78% of window replacement cost when they sell their home. If you are replacing single pane or drafty windows, it’s estimated you could save between $101 and $583 on energy bills with an average of $265 in the Creve Coeur MO Region. (take that Ameren and carbon footprint).

For Creve Coeur residents, it appears that for the year 2024, a small $1200 tax credit is still available. ($250 per door max $500), (windows max $600) and home energy audits ($150).

Common Reasons Homes in 63141 Need New Windows

The homes we serve most often in Creve Coeur were built between 1945 and 1990s. Many of these homes, while rich in character, are burdened with outdated windows, leading to the energy inefficiencies we talked about. Another reason the residents of Creve Coeur replace their windows is before selling their homes. While Fernwood has a middle-class median home price of $398,722, City Center of Creve Coeur and Creve Coeur West have an average real estate price of $761,927, which is more expensive than 98.2% of Missouri neighborhoods. An NAHB study found that 61% of home buyers in the $500k + price range expect new windows to be in the home. Provia windows are perfect for this situation.

In our experience, here are the top signs that indicate it’s time to replace your outdated or failing windows:

If your current windows use old tech and lack multiple Low-E coatings, heat can pass through the glass – forcing your HVAC system to work harder. Upgrading to Energy Star-rated double-paned windows provides better insulation.

Foggy glass or condensation between window panes indicates failing seals and the loss of argon gas. Allowing excess moisture buildup can lead to rot, mold, and significant structural issues over time. We’re ready to assist with practical solutions.

Modern window technology effectively helps dampen unwanted outside noise pollution. If you currently hear a lot of street noise, replacing it with advanced noise-reducing windows will restore peace and quiet back into your home.

Over years of use, window mechanisms can begin sticking or not working smoothly. Installing new replacement windows can restore effortless and reliable functionality, ensuring ease of use.

Indoor-Drafts from broken window seals

Dated, cheaply made, or improperly installed windows allow airflow to pass around weather stripping, causing a breeze or noticeable change in interior temperature.
