OTS Chicago Insulation

OTS Chicago Insulation is a reliable Insulation contractor and General contractor serving Chicago, helping homeowners and businesses boost comfort and cut energy costs with attic, wall, and crawl space upgrades plus air sealing. Ask them about the ideal R-values for Chicago’s climate (attics often target around R-49), whether spray foam, blown-in cellulose, or fiberglass best fits your project, and how they address ventilation and moisture to prevent drafts and ice dams. Request a written proposal that includes an infrared scan to verify coverage, before/after photos, and guidance on available utility rebates or tax credits. Schedule an on-site assessment, confirm cleanup and disposal are included, and get warranty and timeline details in writing so your investment is protected.
