Where We Always Start

Comprehensive Air Sealing

Insulation slows heat transfer. Air sealing stops it. Without sealing the gaps first, even the thickest insulation underperforms — because warm air finds every crack it can.

Before a single fiber of insulation goes in, our technicians conduct a thorough inspection of your attic floor, identifying every point where conditioned air can escape into unconditioned space. We then apply high-grade two-component foam sealant to close those pathways permanently.

Common problem areas include gaps around light fixtures, plumbing and electrical penetrations, attic hatch frames, top plates at interior walls, and chimney chases. These are small openings — but collectively they can account for a significant share of your home’s total heat loss.

Why this matters: The U.S. Department of Energy estimates that air leakage is responsible for 25–40% of heating and cooling energy loss in a typical home. No amount of added insulation compensates for unaddressed air movement.
  • Full attic floor inspection before any work begins
  • Two-component expanding foam applied to all penetrations
  • Light fixture and recessed can sealing
  • Interior wall top plate gap sealing
  • Attic hatch weatherstripping and frame sealing
  • Chimney and flue gap treatment with fire-rated materials where required

Protecting Your Roof

Soffit Vent Cleaning & Airflow Verification

A well-insulated attic that can’t breathe is a problem. Blocked soffit vents trap moisture, raise attic temperatures, and accelerate shingle deterioration — sometimes by years.

Soffit vents sit along the underside of your roofline and form one half of your attic’s passive ventilation system. When they’re blocked — by settled insulation, debris, pests, or previous improper work — air cannot flow from the eaves to the ridge, and the entire attic becomes a closed environment where heat and moisture accumulate.

Before we install insulation, we clear and verify every soffit vent channel to ensure continuous airflow is possible. This is a step that many insulation contractors either skip or address only partially, because it adds time to the job. We include it because cutting it short produces premature failures.

  • Visual inspection and clearing of all soffit vent channels
  • Removal of debris, compressed old insulation, and blockages
  • Verification of ridge vent or exhaust vent function
  • Documentation of ventilation ratio relative to attic square footage
Signs your soffits may be blocked: Ice dams forming along your roofline in winter, unusually high attic temperatures in summer, or visible moisture or mold near the eaves are all indicators that airflow has been compromised.

Keeping Airflow Clear

Baffle Installation

Baffles are channels installed between your roof rafters at the eaves. They create a physical pathway that keeps blown-in insulation from migrating into — and blocking — the soffit vents we just cleared.

Without baffles, blown-in insulation gradually shifts toward the eaves over time, undoing the ventilation work and creating warm, stagnant pockets at the roof deck edge. This is one of the most common causes of ice dams in colder climates, and one of the most preventable.

We install rigid foam or cardboard baffles in every rafter bay that runs to an exterior soffit vent, stapled securely to the roof deck and sealed at the top plate to prevent air bypasses. This ensures the airflow channel remains clear not just on day one, but for the life of the insulation.

  • Rigid baffles installed in all applicable rafter bays
  • Secured and sealed to prevent insulation migration
  • Extends from top plate to clear of insulation depth
  • Coordinates with Step 4 fill depth to maintain airflow channel
  • Prevents ice dam formation at eaves in winter
The long view: Baffles add time and material cost to any job. They’re also the difference between insulation that performs well for 20 years and insulation that starts degrading the roof underneath it within a few.

The Final Layer

Premium R-60 Blown-In Fiberglass Insulation

Only after the attic is sealed, vented, and baffled do we bring in the insulation. By this point, every dollar of material you’re paying for is actually working — not compensating for problems we left behind.

We install premium blown-in fiberglass insulation to R-60, which represents the highest standard for attic thermal resistance recommended for cold-climate regions including northern Illinois. R-60 insulation significantly outperforms the R-38 or R-49 that many contractors install as standard, especially through the temperature extremes this region sees from December through February.

Blown-in fiberglass fills irregularly shaped spaces, flows around obstructions, and settles into a uniform depth across the entire attic floor — providing consistent coverage that batts and rolls can’t always deliver. Our technicians work in calculated passes to reach the correct depth without over-applying or leaving low spots.

Why fiberglass over cellulose: Fiberglass is dimensionally stable, does not absorb moisture, and will not settle or compact significantly over time. In attics with any moisture risk, it outperforms cellulose on longevity.
  • Premium blown-in fiberglass to R-60 standard
  • Depth gauges installed across attic floor for verification
  • Uniform coverage including corners, eave areas, and around obstructions
  • Does not compact significantly over time
  • Moisture-resistant — will not absorb or retain water
  • Compatible with full range of attic configurations

What Every Job Includes

These aren’t add-ons or upgrades. They’re standard on every project we take on.

01

Full Air Sealing Before Insulation

We foam-seal every penetration we can access in the attic floor. Insulation goes in only after this is done.

02

Soffit Vent Clearing & Verification

Every soffit vent channel is cleared and confirmed open before we begin. We don’t fill over blocked ventilation.

03

Baffle Installation in All Rafter Bays

Rigid baffles are installed to keep the airflow channel open at the eaves once insulation is in place.

04

R-60 Premium Blown-In Fiberglass

We install to R-60 — not the code minimum. Depth gauges are placed so you can see the result yourself.

Common Questions

Answers to what homeowners across the western suburbs ask us most.

A few reliable signs: your heating or cooling bills have increased without a change in usage habits, your home feels drafty or has uneven temperatures from room to room, you can see your attic floor joists (they should be buried), or your existing insulation appears compressed, discolored, or wet. If your home was built before 1990 and the insulation hasn’t been touched, it’s almost certainly underperforming by today’s standards. We offer free inspections — we’ll tell you honestly what we find.
It depends on the condition of the existing material. If the old insulation is dry, undamaged, and free of pest activity, we can typically install on top of it and air seal around it — this is the most common scenario. If there’s evidence of moisture damage, significant settling, or pest contamination, removal may be warranted. We assess this during the free inspection and include our recommendation in the written quote.
For a typical single-story home with an accessible attic, the full process — air sealing, vent cleaning, baffle installation, and blown-in fiberglass — generally takes between four and seven hours. Larger homes, homes with complex attic configurations, or projects involving removal of existing material will take longer. We’ll give you a realistic time estimate at the quote stage so you can plan accordingly.
Building codes set the legal minimum — not the performance optimum. In a climate like northern Illinois, where winter temperatures routinely drop well below zero and summers hit the upper 90s, R-49 is a floor, not a target. The additional material cost to go from R-49 to R-60 is modest relative to the incremental energy savings, and R-60 provides meaningful headroom against future utility rate increases. We install to the standard we’d want in our own homes.
Very little. Clear a path to the attic hatch and move any stored items you have in the attic space away from the eaves and attic floor. If you have attic-mounted HVAC equipment or mechanical systems, let us know in advance so we can plan around them. Everything else is on us.
Yes. We’re on call for emergency situations — if a winter storm has exposed a gap or a roof event has compromised your attic, call us at (708) 990-8031. We operate Monday through Saturday, 8am to 8pm, and maintain emergency availability outside those hours for urgent situations.
