For more than three decades, Alpha Development Group has helped homeowners and businesses throughout the Chicagoland area create buildings that are not only beautiful and durable, but also efficient and resilient. As energy costs rise and sustainability becomes increasingly important, weatherization has emerged as one of the smartest investments property owners can make.
At its core, weatherization is about sealing, insulating, and upgrading a building so it can perform at its best year-round — keeping warm air inside during winter, cool air in during summer, and energy waste out all year long. Alpha Development Group brings its 30+ years of construction expertise and its deep understanding of Illinois climate conditions to every weatherization project.
Whether we’re air sealing a century-old bungalow, installing a heat pump system in a modern townhouse, or electrifying an entire commercial property, we deliver results that improve comfort, reduce utility costs, and strengthen Chicagoland’s energy future — one building at a time.
Service Overview: Comprehensive Weatherization Solutions
Weatherization goes beyond simple insulation. It’s a whole-building strategy that ensures every component — from the walls and ducts to the mechanical systems — works efficiently together. At Alpha Development Group, our weatherization services are designed to enhance energy performance while preserving the structural integrity and comfort of your space.
Our weatherization services include:
- Air Sealing – We identify and seal leaks around doors, windows, attics, basements, and crawl spaces to stop conditioned air from escaping. Proper air sealing prevents drafts, improves indoor comfort, and reduces heating and cooling costs.
- Duct Sealing – Leaky ducts waste up to 30% of conditioned air. Our technicians use advanced testing and sealing techniques to improve air distribution and HVAC efficiency.
- Heat Pump HVAC & Water Heaters – We install modern, high-efficiency heat pumps that provide both heating and cooling, reducing reliance on expensive fuels and lowering long-term utility costs.
- Whole-Home Electrification – Transition your home or building away from gas by upgrading systems to electric heat pumps, induction stoves, and smart energy management tools.
- Retrofitting Mechanicals – We modernize outdated systems for better energy performance, safety, and reliability — from boilers and furnaces to ventilation systems and water heaters.
- EV Chargers – As electric vehicles become more common, we help clients prepare by installing efficient, code-compliant charging stations for homes and commercial properties.
- Program Enrollment Assistance – We help you access available state and federal energy incentive programs, including rebates and grants that offset upgrade costs.
- Building Performance Testing – Using diagnostic tools, we assess how your building performs as a complete system, pinpointing areas where energy losses occur.
- Blower Door Testing – This specialized test measures how airtight your building is, helping us target improvements for maximum energy savings.
- Duct Leakage Testing – We test and repair ductwork to ensure your HVAC system operates efficiently, providing balanced airflow throughout your property.
Every weatherization project starts with a thorough assessment of your building’s envelope and systems, allowing us to tailor improvements that deliver measurable results — greater comfort, lower costs, and reduced environmental impact.

Our technicians conduct energy audits, blower door tests, and duct leakage assessments to identify where improvements will have the most impact.
2. Design & Planning
Based on the results, we create a customized weatherization plan. This may include sealing strategies, insulation upgrades, HVAC or mechanical retrofits, and electrification opportunities. We also provide guidance on rebates and energy-efficiency programs available through local utilities and government initiatives.
3. Construction & Implementation
Our certified installers and construction specialists carry out all improvements with precision and care. From advanced air sealing and ductwork upgrades to new heat pump installations, we handle each phase in-house to ensure quality control and code compliance.
4. Final Testing & Verification
After installation, we conduct performance tests — including blower door and duct leakage testing — to confirm measurable results. We verify that all systems meet energy codes and operate at peak efficiency.
Throughout the process, we communicate clearly with homeowners, property managers, and business owners, ensuring every detail is understood and every goal is met.

Case Study: Weatherizing a Historic Chicago Home
When a homeowner in Chicago’s Logan Square neighborhood contacted Alpha Development Group, their 100-year-old brick home was drafty, unevenly heated, and costly to maintain. The family wanted to preserve the home’s charm while making it more efficient and environmentally friendly.
Our team began with blower door and duct leakage tests, identifying significant air loss through the attic, basement, and original window framing. We developed a comprehensive weatherization plan:
- Air sealed attics and crawl spaces.
- Installed a ducted heat pump HVAC system.
- Replaced the gas water heater with a high-efficiency electric model.
- Added smart controls and a home EV charger.
After project completion, the homeowner saw a 35% reduction in annual energy costs and a dramatic improvement in comfort. The home maintained its historic look — but now performed like a modern, efficient building.
This project exemplifies what Alpha Development Group delivers: practical, sustainable solutions tailored to each property’s unique character and needs.
