Our Services
At HPG, we specialize in upgrading aging building systems—restoring reliability, improving efficiency, and extending the long-term value of your property.
Drain, Waste & Vent Systems
Aging cast iron pipes can lead to leaks, water damage, and expensive repairs. If your building is over 35 years old, it may be time to replace the DWV system.
Fire Sprinkler Systems
As a licensed C-20 contractor, we provide complete in-house fire sprinkler services—designed for safety, compliance, and peace of mind.
Fire Alarm Systems
With a lifespan of about 15 years, fire alarm systems require timely upgrades to stay reliable and code-compliant.
Fan Coil Units
Aging FCUs can lead to mold, odors, and leaks. After 20–25 years, inspection or replacement is key to maintaining indoor air quality.
