Valid Line Office

This Chicago insulation contractor helps eliminate drafts, reduce noise, and lower energy bills with spray foam, blown-in cellulose, and thorough air sealing for attics, walls, and crawl spaces. Book an evaluation and ask for infrared scans, R-value targets by area, and a written quote that includes estimated payback, available ComEd/Nicor rebates, and federal tax credits. During installation, expect dust-controlled prep, proper ventilation baffles, meticulous air sealing around lights and penetrations, and a post-job blower door test to verify results. Call to confirm licensing and insurance, product/labor warranties, and a typical 1–3 day turnaround with clean-up and disposal included.
