Oak Park is known for its beautiful historic architecture, but those same charming older homes often come with serious insulation gaps. Our crew has worked inside countless century-old properties in this area, and we understand the specific challenges they present. From balloon-frame walls to unfinished attics with zero insulation, we've seen it all and know how to address it effectively. Every project we take on starts with a thorough assessment so we can recommend the right materials and methods for your specific property.




A homeowner on the east side of Oak Park contacted us about persistent cold spots and high heating bills in their 1920s bungalow. Our team performed a Home Performance Evaluation and found that the attic had only a thin layer of deteriorated insulation and multiple air leaks around the chimney and recessed lights. We removed the old material, air-sealed all penetrations, and installed Blown-In Cellulose Insulation to the recommended R-value. The homeowner reported noticeably warmer rooms and lower energy use within the first billing cycle.
