What We Do

Our Services

Every service backed by the same promise — fast scheduling, transparent pricing, and a seamless experience from quote to completion.

Concrete Lifting (Polyjacking)

Polyurethane foam injection raises sunken concrete slabs back to level in a single day. No demolition, no mess — walk on it in 15 minutes and save up to 70% vs. full slab replacement.

  • Apartment ComplexesMulti-unit property concrete maintenance
  • Void FillingFill underground voids to prevent future settling

Industry average: $3–$8 per sq ft for polyurethane foam injection — up to 70% less than full slab replacement. Every project includes a free estimate.

Blown Insulation

Loose-fill blown insulation — cellulose or fiberglass — is pumped into attics, walls, and hard-to-reach cavities. It fills every gap and irregular space completely, providing excellent thermal coverage at a cost-effective price point.

Ideal for existing homes where you can't easily open walls. Our specialist crews can insulate an average attic in a single day with minimal disruption to your home.

  • Cellulose (recycled) or fiberglass options
  • Ideal for attic floors and hard-to-reach cavities
  • Fills around obstructions, joists, and wiring
  • R-value up to R-60 in attic applications
  • Fire-resistant cellulose treatment available
  • Reduces heating & cooling bills up to 25%

Attic Floors

The #1 most effective insulation upgrade in any home. Stop conditioned air from escaping through the ceiling.

Knee Walls

Finished attic spaces with slanted knee walls are notorious for energy loss — blown insulation seals them completely.

Wall Cavities

Small holes are drilled into exterior walls, insulation is blown in, holes are patched — no drywall demo.

Garage Ceilings

Insulate above attached garages to prevent heat transfer into living spaces above.

Industry average: Blown-in insulation: $1.00–$2.00 per sq ft installed. One of the most cost-effective ways to improve home energy efficiency.

Spray Foam Insulation

Open-Cell Spray Foam

Best for Interior

Expands dramatically, filling every crack and void. Excellent soundproofing. Ideal for interior walls and attic underside applications. R-3.7 per inch.

Closed-Cell Spray Foam

Best for Moisture

Dense, rigid foam with a vapor barrier built in. Highest R-value per inch (R-6.5+). Ideal for crawl spaces, basement walls, and exterior applications.

Rim Joist Sealing

High Impact

The rim joist at the foundation perimeter is one of the leakiest areas in any home. Spray foam here delivers an immediate comfort improvement.

Spray polyurethane foam is the highest-performance insulation available. It simultaneously insulates, air-seals, and — in closed-cell form — acts as a vapor barrier. One product solving three problems.

Illinois homes lose an enormous amount of energy through air infiltration. Spray foam is the only product that can stop both conductive heat loss and air leakage at the same time.

  • Highest R-value per inch of any insulation
  • Air sealing & insulation in a single application
  • Closed-cell acts as a Class II vapor retarder
  • Adds structural rigidity to walls
  • 25–35% energy bill reduction typical
  • Ideal for new construction and retrofits

Industry average: Open-cell: $1.00–$1.50 per sq ft · Closed-cell: $2.00–$3.50 per sq ft. Most homeowners see energy bill reductions of 25–35% after spray foam installation.

Fiberglass Batt Insulation

Fiberglass batt and roll insulation is the proven, cost-effective solution for attic floors, wall cavities, crawl space floor joists, and basement ceilings. Installed in batts that fit precisely between framing members, it delivers reliable thermal performance with fast installation.

Attic Floors

Laid between ceiling joists to create a thermal barrier between living space and unconditioned attic.

  • R-13 to R-38 options
  • Easy access for future work
  • Cost-effective coverage

Exterior Walls

Fitted into wall cavities during new construction or renovation — standard code requirement for exterior walls.

  • R-13, R-15, R-21 options
  • Fire-resistant facing
  • Vapor retarder facing available

Crawl Space Joists

Installed between floor joists to insulate the floor above a crawl space, reducing cold floors above.

  • R-13 to R-30 options
  • Wire support systems included
  • Reduces cold floor syndrome

Basement Ceilings

Insulate between basement ceiling joists to keep heat in living spaces above unfinished basements.

  • Improves first-floor comfort
  • Simple installation
  • Works with any framing

Knee Walls

Finished attic spaces with knee walls benefit from batt insulation on both the wall and floor of these tricky spaces.

  • Stops drafts in finished attics
  • Combined with rigid board
  • Vapor barrier options

Garage Ceilings

Insulate above attached garages to reduce heat transfer into bedrooms or living spaces above.

  • Fire-code compliant facing
  • Reduces HVAC load
  • Quick installation

Industry average: Fiberglass batt insulation: $0.50–$1.50 per sq ft installed. The most affordable insulation option with reliable thermal performance.

Duct Sealing & Cleaning

Duct Sealing

Leaky ductwork can waste 20–30% of conditioned air before it reaches your rooms. We seal joints, connections, and gaps throughout your duct system to maximize HVAC efficiency and eliminate hot and cold spots.

  • Seal leaking joints and connections
  • Reduce energy waste by up to 30%
  • Eliminate uneven heating and cooling
  • Improve overall HVAC performance
  • Extend the life of your HVAC system

Duct Cleaning

Over time, dust, allergens, mold spores, and debris accumulate inside your ducts — recirculating through your home every time the system runs. Professional cleaning restores healthy indoor air quality.

  • Remove dust, debris, and allergen buildup
  • Improve indoor air quality
  • Reduce allergy and respiratory triggers
  • Restore proper airflow throughout home
  • Recommended every 3–5 years

Pro tip: Combine duct sealing with insulation upgrades for maximum energy savings — sealed ducts ensure all that conditioned air actually reaches your living spaces.

Crawl Space & Inspections

Crawl Space Encapsulation

An unencapsulated crawl space is one of the biggest sources of moisture, mold, and energy loss in Chicagoland homes. We seal, insulate, and protect this critical space.

  • Heavy-duty vapor barrier installation
  • Spray foam or rigid board on foundation walls
  • Insulation of floor joists above
  • Moisture control and drainage solutions
  • Eliminates cold floors in winter
  • Improves indoor air quality throughout home

Home Energy Inspection

We use infrared thermal imaging to show you exactly where your home is losing heat or cool air — before recommending any solution. You see the data, you make the call.

  • Infrared camera thermal imaging scan
  • Full written report of findings
  • Identifies hidden air leaks and voids
  • No-pressure: findings are yours to keep
  • Prioritized recommendations by ROI
  • Included with qualifying insulation estimates

Industry average: Crawl space encapsulation: $3–$7 per sq ft depending on scope. Energy inspections are often included free with a qualifying insulation estimate.
