Energy Efficient

Infinity from Marvin windows are engineered to significantly improve a home's energy efficiency. Made with Ultrex^® fiberglass frames and advanced glass technology, these windows minimize heat transfer, helping to maintain a consistent indoor temperature throughout the year. Their tight seals prevent air leaks, reducing the strain on heating and cooling systems and lowering overall energy consumption. Homeowners benefit from a more comfortable living environment and potentially reduced utility bills. By choosing Infinity from Marvin, you invest in energy-efficient replacement windows that contribute to a greener home.

Durable

Infinity from Marvin windows are designed to withstand harsh weather conditions, including intense heat, heavy rain, and strong winds, without warping, cracking, or fading. Ultrex resists expanding and contracting with temperature changes, which helps maintain a secure, airtight fit year after year. This advanced material ensures that Infinity windows deliver lasting performance with minimal maintenance, providing homeowners with peace of mind and long-term value.

Renovation Work on Homes Built Before 1978

Custom Exteriors is EPA Lead-Safe Renovation, Repair, and Painting (RRP) Certified, a federal certification required for renovation work on homes built before 1978, where lead-based paint may still be present. Many homes across Pleasanton, Livermore, Walnut Creek, and other established East Bay neighborhoods fall into this category. Before installation begins, our team confirms whether lead-safe procedures apply to your project and follows the required practices to protect your home, your family, and our crew. It's one more credential that separates a certified, accountable contractor from one that isn't.
