Window Benefits

Aesthetics. Quality windows and superior window installation services enhance your home’s look on both the inside and outside.

Energy Efficiency. Many Chicago-area homes have drafty, rattling windows that leak heat in the winter and cool air in the summer. New energy-efficient windows from Marvin can significantly reduce your heating and cooling bills.

Maintenance. Older windows necessitate maintenance: scraping, painting, caulking, and weather-stripping to increase energy efficiency. Many newer windows feature low-maintenance frames that require only minimal maintenance.

Performance. You’ll notice a significant increase in comfort once your windows are installed. No more drafts that give you the chills! You’ll also enjoy seeing the crisp clarity of the great outdoors through your new, high-quality windows.

Door Benefits

Aesthetics. Because your front door is the centerpiece of your home’s entrance, a new door is a worthwhile investment in the beauty of your home. And if you plan to sell your house in the future, keep in mind that a door upgrade enhances curb appeal, adding value and increasing buyer interest.

Energy Efficiency. Old doors reduce your home’s energy efficiency. Drafts are one of the biggest drains on the energy efficiency of your home, adding up to real dollars on your heating and cooling bills. A new, energy-efficient door helps lower your utility bills.

Maintenance. Older doors have seen a lot of use and therefore require maintenance: scraping and painting. Newer doors feature low-maintenance cladding, which is a protective exterior covering that requires minimal maintenance.

Performance. This is perhaps the most compelling reason to replace a door. On top of testing your patience, damaged or inferior doors can impact your safety, and they aren’t giving you the optimum benefit in terms of convenience and efficiency.
