Attic Insulation Installation

Stop losing heat through your roof and start seeing the difference on your energy bill every single month.

Attic Insulation Installation

The attic is the single biggest source of heat loss in most Chicago-area homes — and most homeowners have no idea until the energy bills tell them. Cold seeping down from above, rooms that never quite reach the right temperature, a heating system that runs constantly but cannot keep up. These are not random problems. They are the result of insulation that is either missing, deteriorated, or was never installed correctly to begin with. We approach every attic the same way — look at what is actually there, assess what is working and what is not, and give you an honest picture of what your home needs.

No two attics are identical. Older homes in Des Plaines and Schaumburg often have original insulation that has compacted down to a fraction of its original R-value. Homes in Arlington Heights and Naperville with finished attic spaces have their own set of challenges around sloped ceilings and knee walls. We work with blown-in fiberglass, blown-in cellulose, and batt insulation depending on what the space requires and what will perform best long-term. Where existing insulation is damaged, contaminated, or past its useful life, we remove it completely before anything new goes in. The installation is done to the correct R-value for Illinois climate — not just enough to pass a quick visual check.

When the attic is done right, you feel it. Rooms hold temperature longer. The heating system does not have to work as hard. Your energy bills reflect it month after month. That is the outcome we are working toward on every attic job we take on across Chicago and the surrounding suburbs. If you are ready to find out what your attic actually needs — and get it fixed properly — reach out to OTS Chicago Insulation for a free estimate. We will tell you exactly what we find and exactly what it will take to fix it.

What We Offer:

  • Attic Insulation Assessment — We inspect your current attic insulation before recommending anything. This includes checking R-value, coverage gaps, moisture damage, and settling that reduces thermal performance.

  • Old Insulation Removal — Damaged, contaminated, or severely deteriorated insulation is removed completely before new material is installed. Starting clean means the new installation performs the way it should.

  • Blown-In Fiberglass Insulation — Ideal for achieving even, consistent coverage across irregular attic floors. Fills gaps and hard-to-reach areas that batt insulation cannot address effectively.

  • Blown-In Cellulose Insulation — A dense, tightly packed option that provides excellent thermal performance and works particularly well in older Chicago-area homes where air sealing is also a concern.

  • Batt Insulation Installation — Pre-cut fiberglass or rockwool panels installed between attic joists for open attic spaces and renovation projects requiring precise, fitted coverage.

  • Sloped Ceiling & Knee Wall Insulation — Finished attic spaces with sloped ceilings and knee walls require a different approach. We insulate these areas correctly so the entire upper level of your home performs consistently.

  • Air Sealing Alongside Insulation — Gaps around penetrations, fixtures, and the attic hatch are sealed before insulation goes in. Insulation without air sealing leaves energy loss paths open that material alone cannot fix.

Why Choose OTS Chicago Insulation for Attic Insulation Installation

  • Honest Assessment Before Any Work Begins — We look at your attic and tell you what it actually needs. If it only needs a top-up, that is what we recommend. We do not push full replacement when partial improvement is the right call.

  • Installed to the Correct R-Value for Illinois — Chicago winters require a specific thermal performance standard. We install to the R-value your home needs for this climate — not a minimum that just meets a basic requirement on paper.

  • Removal Done Right — Old, damaged insulation that stays under new material reduces the performance of everything above it. We remove what needs to come out completely and clean the space before installation begins.

  • One Team From Start to Finish — The same team that assesses your attic installs the insulation. There is no handoff to a separate crew and no drop in quality between what was promised and what gets delivered.

  • Serving Chicago and the Surrounding Suburbs — We work across Des Plaines, Schaumburg, Arlington Heights, Naperville, Evanston, Palatine, and more. Local experience means we understand the specific insulation challenges homes in this area face every winter.
