Insulation That Performs—See the Results

Our Process for Insulation Installation

These are the steps our insulation contractor in Mattoon, IL takes for any commercial or residential project:

1. Initial conversation and scheduling: Contact our office and we’ll set up a convenient time to visit. We offer flexible appointment windows and provide a free estimate by the next business day so you can move forward quickly.
2. On-site assessment: Our technician walks the property, reviews attic, wall, crawl space, and basement conditions, and discusses your comfort goals, moisture concerns, and budget. We also note ventilation and code requirements.
3. Customized recommendations: Based on your space and performance targets, we propose the right mix of spray foam, fiberglass wall, or blown-in insulation. You’ll receive a clear scope, timeline, and pricing—no surprises.
4. Preparation and protection: Before any work begins, we cover walkways and work areas, protect finishes, and stage equipment. Safety is a priority, and our fully insured crew follows strict jobsite protocols.
5. Air sealing and detail work: We seal obvious gaps, penetrations, and rim joists where applicable. Addressing leaks first helps your new insulation perform better and keeps conditioned air where it belongs.
6. Professional installation: Our team installs the specified materials to the targeted R-values and depths, with even coverage and clean edges. We pay special attention to thermal bypasses, transitions, and hard-to-reach areas.
7. Quality checks during the job: We verify coverage, depth, and adhesion (for foam) as we go, and confirm that baffles, vents, and service clearances remain accessible for future maintenance.
8. Clean, careful wrap-up: After installation, we tidy the space, remove debris, and return access points to their original condition. We walk you through the completed work and answer any questions.
9. Post-install verification: We review the results, discuss expected comfort and energy savings, and provide documentation for rebates or tax credits when applicable. We can also schedule follow-up checks on request.
10. Clear handoff and support: You’ll receive a detailed invoice, product information, and our contact details for future service. With easy scheduling and competitive pricing, we’re here whenever you need us.
