Illinois' climate, with its cold winters and hot summers, requires window installations that provide superior insulation and prevent air infiltration. Our installation process begins with a thorough assessment of your current windows and framing. We then carefully remove the old window unit, ensuring a clean and protected work environment. The window opening is meticulously prepared to create a solid, level surface for the new installation. New windows are precisely measured, fitted, and secured. The final steps involve applying high-quality sealants and insulation to create a weather-tight barrier, crucial for minimizing heat loss in winter and heat gain in summer for Chicago homes.
