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.

Manchester Homeowners See Real Value with Our Services!

Over the past two years, home values in Manchester have risen by nearly 20%, a trend that underscores the solid investment of upgrading your windows. According to energystar.gov, homeowners can anticipate recouping about 78% of the cost of window replacements at sale time.

For those replacing single-pane or inefficient windows, the savings is even more compelling. Manchester residents can expect to save between $101 and $583 annually on their energy bills, with an average saving of $265. This not only means more money in your pocket but also a significant reduction in your home’s energy consumption. (Take that Ameren and carbon footprint).

For Missouri 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 This Area Need New Windows

Manchester’s architectural diversity, from the modern apartments and homes in Twin Oaks to the charming, historical residences in South and East Manchester, presents unique challenges and opportunities. Many homes, especially those built between 1940 and 1969, boast distinct character but often come with less efficient, outdated windows.

In our experience, these common reasons prompt homeowners to consider replacing their outdated or failing windows: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.

Schedule a free inspection to have us inspect your windows. A window specialist will give an honest opinion if you need simple repairs or if it’s time to invest in replacement windows.
