RECENT WYANDOTTE PROJECT
A recent project in the Oak Street historic district highlights the versatility of our services. The homeowners were facing severe drafts and street noise in their 1920s craftsman home. We performed a complete retrofit, removing the old, settled dust and replacing it with modern insulation that preserves the home’s character while bringing it up to 21st-century energy standards.
Project Completed: Insulation removal of damaged material followed by the installation of closed-cell spray foam in the rim joists and attic slopes, significantly reducing air leakage and external noise.
