OTS Chicago Insulation was started by Ofer Tsemah after spending more than a decade working directly inside homes, fixing comfort issues and improving energy efficiency across the Chicago area. Years in the field taught him that homeowners need clear answers and honest guidance, not quick sales. He built the company around that promise. Today, we remain a locally owned team that uses quality materials, careful installation, and proven building science to deliver long-lasting results. Our goal is simple: help homeowners enjoy healthier air, steadier temperatures, and a more efficient home they can rely on for years.
Our attic insulation process boosts R-value, limits heat transfer, and helps your home maintain steady comfort levels through every season.
We insulate and encapsulate crawl spaces to manage moisture, reduce energy loss, and protect your property’s foundation.
Spray foam insulation expands to seal gaps and create a strong thermal barrier. This improves energy efficiency and indoor comfort.
We install acoustic insulation to quiet rooms, reduce outside noise, and improve sound clarity throughout your space.
Wall insulation increases thermal resistance, enhances comfort, and lowers energy bills by reducing heat escape.
We add insulation to rim joists and basement walls to eliminate cold spots and moisture issues, improving home performance.
Air sealing minimizes unwanted airflow and supports insulation efficiency. This boosts comfort and reduces HVAC stress.
Duct insulation keeps heated and cooled air contained, improving HVAC performance and lowering energy consumption.
Better insulation helps your home hold temperature longer, which lowers heating and cooling use.
Well-sealed attics, walls, and crawl spaces keep every room feeling stable and comfortable.
Quality materials limit noise intrusion and support healthier indoor air by reducing drafts and moisture.
“I live in Buffalo Grove, IL, and recently hired OTS Chicago Insulation to insulate my crawl space and I’m extremely happy with the results! After doing some research and calling a few companies, I chose OTS because of their professional approach and detailed consultation. Ofer, the technician who came out, was knowledgeable and explained the benefits of crawl space insulation, including how it would improve energy efficiency and reduce moisture issues in my home.It’s been a few months since the installation, and I’ve noticed a big difference. The floors on the first level are no longer cold, the air quality has improved, and our heating system isn’t working as hard. This means real energy savings!

Seasonal heat can expose weak attic or wall insulation that winter temperatures hide. Warm air enters faster, making rooms uneven. An insulation inspection can show which areas need stronger materials.
Yes. Uneven floors usually mean attic insulation is thin or airflow is poor. Adding the right insulation service can balance temperatures and reduce strain on your cooling system.
Many older homes near areas like Uptown have aging insulation or air gaps behind walls. Upgrading insulation can reduce heat loss and make the home feel steady during cold seasons.
Musty smells often come from moisture under the home. Crawl space insulation or encapsulation can block moisture and help protect the structure. A quick check is the safest first step.
Repair is enough when only a small area is damaged. Full replacement is better when insulation is wet, old, or sagging. A contractor can explain the cost difference after inspecting your attic or crawl space.
