Open & closed-cell spray foam — applied in controlled layers to seal gaps and cavities for an airtight envelope.

We start by inspecting the area, fixing moisture issues, and masking off surfaces. Crews wear full protective gear with proper ventilation set up. We mix and calibrate the foam equipment for correct temperature and pressure, then apply it evenly in controlled layers. Finally we trim excess and confirm the install is airtight and meets performance standards. (Jamie adding closed-cell spray foam to knee walls — 5.5" R38, to code.)

Blown-in fiberglass or cellulose, evenly distributed to the right depth for the desired R-value.

We inspect attic or wall cavities for air leaks, moisture, and proper ventilation. Gaps around pipes, wires, and openings are sealed first to improve efficiency. Then we set up the blowing machine and prepare the loose-fill material — fiberglass or cellulose — and blow it in evenly to the correct depth. We confirm vents stay clear and coverage is uniform. (Jamie blowing insulation.)

Top-down attic systems — air seal, insulate, and ventilate. The right way, every time.

We start by inspecting the space for air leaks, moisture issues, and proper ventilation. The crew seals gaps and cracks around ducts, wiring, and openings to improve energy efficiency. We then choose the appropriate insulation material and R-value for the climate and code, install with even coverage (without blocking vents or compressing material), and verify consistent thickness and proper airflow.

Safe, contained removal of old, damaged, or contaminated insulation — including varmint-infested loose fill.

We inspect the attic for hazards like mold, pests, or asbestos and set up proper ventilation. Crews wear gloves, goggles, and respirators. Specialized vacuums remove the old insulation while minimizing dust and debris. Material is sealed in heavy-duty bags and disposed of per local regulations. The space is then cleaned and sanitized, ready for new insulation if needed. (Denni in proper gear removing varmint-infested loose fill.)

Vapor barrier, sealing, and insulation that ends cold floors and humidity issues for good.

We inspect for moisture, standing water, pests, and structural issues. Vents and gaps get sealed, then a heavy-duty vapor barrier is installed across the ground and up the walls. Seams are overlapped and taped tight, with the liner secured to create a continuous moisture barrier. We may add insulation and a dehumidifier to control humidity. Finally we confirm the space is fully sealed and dry. (Mr. Martinez's crawl space in Illinois — 3 days of work.)

Spray foam, fiberglass, or rigid board for commercial buildings — coordinated to your construction schedule.

We review building plans and assess energy codes, safety, and site conditions. We coordinate with other trades so insulation work fits the construction schedule and system layouts. Materials are selected based on performance and building use. Specialized equipment lets us cover large areas efficiently while sealing air leaks and thermal bridges. We finish with full inspection for compliance, coverage, and energy-efficiency standards. (Luis, Juan, and Jamie filling a commercial building.)

High-density wall fills that stop drafts cold in older Chicagoland homes — no drywall demo.

We drill small access holes in the siding or interior wall, then inject cellulose at high density (3.5+ lbs/cu ft) so the wall cavity is packed solid with no settling or voids. Holes are plugged and finished. You get a quieter, draft-free wall with a real R-value upgrade — without tearing into your finished living space. Ideal for bungalows, foursquares, and pre-1970s ranches.

Standard and high-density fiberglass batts for new construction and renovations.

We size batts to fit each cavity precisely — no compression, no gaps, no fishmouths around wiring or plumbing. Vapor barriers are installed per code for your climate zone. Best fit for new construction, additions, garages, and finished basements where stud bays are open and accessible.

Duct sealing and HVAC services that pair with your insulation upgrade.

Leaky ducts can waste 20–30% of conditioned air before it reaches your rooms. We seal supply and return ducts with mastic and metal tape, insulate ducts in unconditioned spaces, and verify static pressure. Combined with attic air sealing, this is one of the highest-ROI moves you can make in an older home.

Gutter installation and protection — keep water away from your envelope.

Bad drainage is the #1 enemy of insulation. We install seamless 5" or 6" aluminum gutters, properly pitched downspouts, and gutter guards to keep leaves out. Done together with your insulation work, your home stays dry, your basement stays dry, and your walls stop wicking moisture into the cavities we just packed.

Humane wildlife removal and entry-point sealing for attics and crawl spaces.

Squirrels, raccoons, mice, bats — they get into attics and contaminate insulation with droppings, urine, and chewed wiring. We trap or exclude them humanely, identify and seal every entry point (eaves, soffits, roof vents, foundation gaps), then remove and replace the contaminated insulation. Pairs with our Insulation Removal service.

Mold remediation and proper attic / bath ventilation done to code.

Most attic mold isn't a mold problem — it's a moisture problem caused by bad ventilation and bath fans dumping into the attic. We remediate the mold, then fix the root cause: balanced soffit-to-ridge ventilation, baffles to keep airflow open, and bath/dryer fans ducted properly through the roof or wall. The mold doesn't come back.

Stop drafts at the source — caulk, foam, and weatherstripping at every leak point.

Air sealing is the single highest-ROI move in any older home. We trace airflow at top plates, can lights, attic hatches, rim joists, and around HVAC penetrations — then seal each one with the right material (fire-rated foam at chases, caulk at framing, gasket kits at hatches). Pairs with attic and wall insulation for a real envelope upgrade. Verified with a blower door test before-and-after.

Full BPI-style diagnostic — thermal imaging + blower door + moisture mapping.

We bring a calibrated blower door, thermal camera, moisture meters, and a CO/combustion analyzer. You get a written report showing exactly where energy and dollars are leaving — with a prioritized fix list and rebate eligibility flagged for each item. This is the same audit format the energy auditors use, performed by a BPI-certified owner-operator.

Up to $1,800 in NICOR rebates — we file the paperwork for you.

We are an approved NICOR Gas and ComEd rebate contractor. Eligible attic insulation and air-sealing jobs typically qualify for $1,000–$1,800 back, with bonus rebates stacked on for low-income and high-efficiency homes. We pre-qualify your home, file all paperwork, and the check comes directly to you — usually within 6–8 weeks of completion.
